| 3 | This file is built by metaconfig. |
| 4 | |
| 5 | This file contains a description of all the shell variables whose value is |
| 6 | determined by the Configure script. Variables intended for use in C |
| 7 | programs (e.g. I_UNISTD) are already described in config_h.SH. [`configpm' |
| 8 | generates pod documentation for Config.pm from this file--please try to keep |
| 9 | the formatting regular.] |
| 10 | |
| 11 | _a (Unix.U): |
| 12 | This variable defines the extension used for ordinary library files. |
| 13 | For unix, it is '.a'. The '.' is included. Other possible |
| 14 | values include '.lib'. |
| 15 | |
| 16 | _exe (Unix.U): |
| 17 | This variable defines the extension used for executable files. |
| 18 | DJGPP, Cygwin and OS/2 use '.exe'. Stratus VOS uses '.pm'. |
| 19 | On operating systems which do not require a specific extension |
| 20 | for executable files, this variable is empty. |
| 21 | |
| 22 | _o (Unix.U): |
| 23 | This variable defines the extension used for object files. |
| 24 | For unix, it is '.o'. The '.' is included. Other possible |
| 25 | values include '.obj'. |
| 26 | |
| 27 | afs (afs.U): |
| 28 | This variable is set to 'true' if AFS (Andrew File System) is used |
| 29 | on the system, 'false' otherwise. It is possible to override this |
| 30 | with a hint value or command line option, but you'd better know |
| 31 | what you are doing. |
| 32 | |
| 33 | afsroot (afs.U): |
| 34 | This variable is by default set to '/afs'. In the unlikely case |
| 35 | this is not the correct root, it is possible to override this with |
| 36 | a hint value or command line option. This will be used in subsequent |
| 37 | tests for AFSness in the configure and test process. |
| 38 | |
| 39 | alignbytes (alignbytes.U): |
| 40 | This variable holds the number of bytes required to align a |
| 41 | double-- or a long double when applicable. Usual values are |
| 42 | 2, 4 and 8. The default is eight, for safety. |
| 43 | |
| 44 | ansi2knr (ansi2knr.U): |
| 45 | This variable is set if the user needs to run ansi2knr. |
| 46 | Currently, this is not supported, so we just abort. |
| 47 | |
| 48 | aphostname (d_gethname.U): |
| 49 | This variable contains the command which can be used to compute the |
| 50 | host name. The command is fully qualified by its absolute path, to make |
| 51 | it safe when used by a process with super-user privileges. |
| 52 | |
| 53 | api_revision (patchlevel.U): |
| 54 | The three variables, api_revision, api_version, and |
| 55 | api_subversion, specify the version of the oldest perl binary |
| 56 | compatible with the present perl. In a full version string |
| 57 | such as '5.6.1', api_revision is the '5'. |
| 58 | Prior to 5.5.640, the format was a floating point number, |
| 59 | like 5.00563. |
| 60 | |
| 61 | perl.c:incpush() and lib/lib.pm will automatically search in |
| 62 | $sitelib/.. for older directories back to the limit specified |
| 63 | by these api_ variables. This is only useful if you have a |
| 64 | perl library directory tree structured like the default one. |
| 65 | See INSTALL for how this works. The versioned site_perl |
| 66 | directory was introduced in 5.005, so that is the lowest |
| 67 | possible value. The version list appropriate for the current |
| 68 | system is determined in inc_version_list.U. |
| 69 | |
| 70 | XXX To do: Since compatibility can depend on compile time |
| 71 | options (such as bincompat, longlong, etc.) it should |
| 72 | (perhaps) be set by Configure, but currently it isn't. |
| 73 | Currently, we read a hard-wired value from patchlevel.h. |
| 74 | Perhaps what we ought to do is take the hard-wired value from |
| 75 | patchlevel.h but then modify it if the current Configure |
| 76 | options warrant. patchlevel.h then would use an #ifdef guard. |
| 77 | |
| 78 | api_subversion (patchlevel.U): |
| 79 | The three variables, api_revision, api_version, and |
| 80 | api_subversion, specify the version of the oldest perl binary |
| 81 | compatible with the present perl. In a full version string |
| 82 | such as '5.6.1', api_subversion is the '1'. See api_revision for |
| 83 | full details. |
| 84 | |
| 85 | api_version (patchlevel.U): |
| 86 | The three variables, api_revision, api_version, and |
| 87 | api_subversion, specify the version of the oldest perl binary |
| 88 | compatible with the present perl. In a full version string |
| 89 | such as '5.6.1', api_version is the '6'. See api_revision for |
| 90 | full details. As a special case, 5.5.0 is rendered in the |
| 91 | old-style as 5.005. (In the 5.005_0x maintenance series, |
| 92 | this was the only versioned directory in $sitelib.) |
| 93 | |
| 94 | api_versionstring (patchlevel.U): |
| 95 | This variable combines api_revision, api_version, and |
| 96 | api_subversion in a format such as 5.6.1 (or 5_6_1) suitable |
| 97 | for use as a directory name. This is filesystem dependent. |
| 98 | |
| 99 | ar (Loc.U): |
| 100 | This variable is used internally by Configure to determine the |
| 101 | full pathname (if any) of the ar program. After Configure runs, |
| 102 | the value is reset to a plain "ar" and is not useful. |
| 103 | |
| 104 | archlib (archlib.U): |
| 105 | This variable holds the name of the directory in which the user wants |
| 106 | to put architecture-dependent public library files for $package. |
| 107 | It is most often a local directory such as /usr/local/lib. |
| 108 | Programs using this variable must be prepared to deal |
| 109 | with filename expansion. |
| 110 | |
| 111 | archlibexp (archlib.U): |
| 112 | This variable is the same as the archlib variable, but is |
| 113 | filename expanded at configuration time, for convenient use. |
| 114 | |
| 115 | archname (archname.U): |
| 116 | This variable is a short name to characterize the current |
| 117 | architecture. It is used mainly to construct the default archlib. |
| 118 | |
| 119 | archname64 (use64bits.U): |
| 120 | This variable is used for the 64-bitness part of $archname. |
| 121 | |
| 122 | archobjs (Unix.U): |
| 123 | This variable defines any additional objects that must be linked |
| 124 | in with the program on this architecture. On unix, it is usually |
| 125 | empty. It is typically used to include emulations of unix calls |
| 126 | or other facilities. For perl on OS/2, for example, this would |
| 127 | include os2/os2.obj. |
| 128 | |
| 129 | asctime_r_proto (d_asctime_r.U): |
| 130 | This variable encodes the prototype of asctime_r. |
| 131 | It is zero if d_asctime_r is undef, and one of the |
| 132 | REENTRANT_PROTO_T_ABC macros of reentr.h if d_asctime_r |
| 133 | is defined. |
| 134 | |
| 135 | awk (Loc.U): |
| 136 | This variable is used internally by Configure to determine the |
| 137 | full pathname (if any) of the awk program. After Configure runs, |
| 138 | the value is reset to a plain "awk" and is not useful. |
| 139 | |
| 140 | baserev (baserev.U): |
| 141 | The base revision level of this package, from the .package file. |
| 142 | |
| 143 | bash (Loc.U): |
| 144 | This variable is defined but not used by Configure. |
| 145 | The value is the empty string and is not useful. |
| 146 | |
| 147 | bin (bin.U): |
| 148 | This variable holds the name of the directory in which the user wants |
| 149 | to put publicly executable images for the package in question. It |
| 150 | is most often a local directory such as /usr/local/bin. Programs using |
| 151 | this variable must be prepared to deal with ~name substitution. |
| 152 | |
| 153 | bin_ELF (dlsrc.U): |
| 154 | This variable saves the result from configure if generated binaries |
| 155 | are in ELF format. Only set to defined when the test has actually |
| 156 | been performed, and the result was positive. |
| 157 | |
| 158 | binexp (bin.U): |
| 159 | This is the same as the bin variable, but is filename expanded at |
| 160 | configuration time, for use in your makefiles. |
| 161 | |
| 162 | bison (Loc.U): |
| 163 | This variable is used internally by Configure to determine the |
| 164 | full pathname (if any) of the bison program. After Configure runs, |
| 165 | the value is reset to a plain "bison" and is not useful. |
| 166 | |
| 167 | byacc (Loc.U): |
| 168 | This variable is used internally by Configure to determine the |
| 169 | full pathname (if any) of the byacc program. After Configure runs, |
| 170 | the value is reset to a plain "byacc" and is not useful. |
| 171 | |
| 172 | byteorder (byteorder.U): |
| 173 | This variable holds the byte order in a UV. In the following, |
| 174 | larger digits indicate more significance. The variable byteorder |
| 175 | is either 4321 on a big-endian machine, or 1234 on a little-endian, |
| 176 | or 87654321 on a Cray ... or 3412 with weird order ! |
| 177 | |
| 178 | c (n.U): |
| 179 | This variable contains the \c string if that is what causes the echo |
| 180 | command to suppress newline. Otherwise it is null. Correct usage is |
| 181 | $echo $n "prompt for a question: $c". |
| 182 | |
| 183 | castflags (d_castneg.U): |
| 184 | This variable contains a flag that precise difficulties the |
| 185 | compiler has casting odd floating values to unsigned long: |
| 186 | 0 = ok |
| 187 | 1 = couldn't cast < 0 |
| 188 | 2 = couldn't cast >= 0x80000000 |
| 189 | 4 = couldn't cast in argument expression list |
| 190 | |
| 191 | cat (Loc.U): |
| 192 | This variable is used internally by Configure to determine the |
| 193 | full pathname (if any) of the cat program. After Configure runs, |
| 194 | the value is reset to a plain "cat" and is not useful. |
| 195 | |
| 196 | cc (cc.U): |
| 197 | This variable holds the name of a command to execute a C compiler which |
| 198 | can resolve multiple global references that happen to have the same |
| 199 | name. Usual values are 'cc' and 'gcc'. |
| 200 | Fervent ANSI compilers may be called 'c89'. AIX has xlc. |
| 201 | |
| 202 | cccdlflags (dlsrc.U): |
| 203 | This variable contains any special flags that might need to be |
| 204 | passed with 'cc -c' to compile modules to be used to create a shared |
| 205 | library that will be used for dynamic loading. For hpux, this |
| 206 | should be +z. It is up to the makefile to use it. |
| 207 | |
| 208 | ccdlflags (dlsrc.U): |
| 209 | This variable contains any special flags that might need to be |
| 210 | passed to cc to link with a shared library for dynamic loading. |
| 211 | It is up to the makefile to use it. For sunos 4.1, it should |
| 212 | be empty. |
| 213 | |
| 214 | ccflags (ccflags.U): |
| 215 | This variable contains any additional C compiler flags desired by |
| 216 | the user. It is up to the Makefile to use this. |
| 217 | |
| 218 | ccflags_uselargefiles (uselfs.U): |
| 219 | This variable contains the compiler flags needed by large file builds |
| 220 | and added to ccflags by hints files. |
| 221 | |
| 222 | ccname (Checkcc.U): |
| 223 | This can set either by hints files or by Configure. If using |
| 224 | gcc, this is gcc, and if not, usually equal to cc, unimpressive, no? |
| 225 | Some platforms, however, make good use of this by storing the |
| 226 | flavor of the C compiler being used here. For example if using |
| 227 | the Sun WorkShop suite, ccname will be 'workshop'. |
| 228 | |
| 229 | ccsymbols (Cppsym.U): |
| 230 | The variable contains the symbols defined by the C compiler alone. |
| 231 | The symbols defined by cpp or by cc when it calls cpp are not in |
| 232 | this list, see cppsymbols and cppccsymbols. |
| 233 | The list is a space-separated list of symbol=value tokens. |
| 234 | |
| 235 | ccversion (Checkcc.U): |
| 236 | This can set either by hints files or by Configure. If using |
| 237 | a (non-gcc) vendor cc, this variable may contain a version for |
| 238 | the compiler. |
| 239 | |
| 240 | cf_by (cf_who.U): |
| 241 | Login name of the person who ran the Configure script and answered the |

| 243 | |
| 244 | cf_email (cf_email.U): |
| 245 | Electronic mail address of the person who ran Configure. This can be |
| 246 | used by units that require the user's e-mail, like MailList.U. |
| 247 | |
| 248 | cf_time (cf_who.U): |
| 249 | Holds the output of the "date" command when the configuration file was |
| 250 | produced. This is used to tag both config.sh and config_h.SH. |
| 251 | |
| 252 | charbits (charsize.U): |
| 253 | This variable contains the value of the CHARBITS symbol, which |
| 254 | indicates to the C program how many bits there are in a character. |
| 255 | |
| 256 | charsize (charsize.U): |
| 257 | This variable contains the value of the CHARSIZE symbol, which |
| 258 | indicates to the C program how many bytes there are in a character. |
| 259 | |

| 263 | |
| 264 | chmod (Loc.U): |
| 265 | This variable is used internally by Configure to determine the |
| 266 | full pathname (if any) of the chmod program. After Configure runs, |

| 271 | The value is the empty string and is not useful. |
| 272 | |
| 273 | clocktype (d_times.U): |
| 274 | This variable holds the type returned by times(). It can be long, |
| 275 | or clock_t on BSD sites (in which case <sys/types.h> should be |
| 276 | included). |
| 277 | |
| 278 | comm (Loc.U): |
| 279 | This variable is used internally by Configure to determine the |
| 280 | full pathname (if any) of the comm program. After Configure runs, |
| 281 | the value is reset to a plain "comm" and is not useful. |

| 296 | |
| 297 | config_args (Options.U): |
| 298 | This variable contains a single string giving the command-line |
| 299 | arguments passed to Configure. Spaces within arguments, |
| 300 | quotes, and escaped characters are not correctly preserved. |
| 301 | To reconstruct the command line, you must assemble the individual |
| 302 | command line pieces, given in config_arg[0-9]*. |
| 303 | |
| 304 | contains (contains.U): |
| 305 | This variable holds the command to do a grep with a proper return |
| 306 | status. On most sane systems it is simply "grep". On insane systems |
| 307 | it is a grep followed by a cat followed by a test. This variable |
| 308 | is primarily for the use of other Configure units. |
| 309 | |
| 310 | cp (Loc.U): |
| 311 | This variable is used internally by Configure to determine the |
| 312 | full pathname (if any) of the cp program. After Configure runs, |

| 330 | when it calls cpp. The symbols defined by the cc alone or cpp |
| 331 | alone are not in this list, see ccsymbols and cppsymbols. |
| 332 | The list is a space-separated list of symbol=value tokens. |
| 333 | |
| 334 | cppflags (ccflags.U): |
| 335 | This variable holds the flags that will be passed to the C pre- |
| 336 | processor. It is up to the Makefile to use it. |
| 337 | |
| 338 | cpplast (cppstdin.U): |
| 339 | This variable has the same functionality as cppminus, only it applies |
| 340 | to cpprun and not cppstdin. |
| 341 | |
| 342 | cppminus (cppstdin.U): |
| 343 | This variable contains the second part of the string which will invoke |
| 344 | the C preprocessor on the standard input and produce to standard |
| 345 | output. This variable will have the value "-" if cppstdin needs |
| 346 | a minus to specify standard input, otherwise the value is "". |
| 347 | |
| 348 | cpprun (cppstdin.U): |
| 349 | This variable contains the command which will invoke a C preprocessor |
| 350 | on standard input and put the output to stdout. It is guaranteed not |
| 351 | to be a wrapper and may be a null string if no preprocessor can be |
| 352 | made directly available. This preprocessor might be different from the |
| 353 | one used by the C compiler. Don't forget to append cpplast after the |
| 354 | preprocessor options. |
| 355 | |
| 356 | cppstdin (cppstdin.U): |
| 357 | This variable contains the command which will invoke the C |
| 358 | preprocessor on standard input and put the output to stdout. |
| 359 | It is primarily used by other Configure units that ask about |
| 360 | preprocessor symbols. |
| 361 | |
| 362 | cppsymbols (Cppsym.U): |
| 363 | The variable contains the symbols defined by the C preprocessor |
| 364 | alone. The symbols defined by cc or by cc when it calls cpp are |
| 365 | not in this list, see ccsymbols and cppccsymbols. |

| 367 | |
| 368 | crypt_r_proto (d_crypt_r.U): |
| 369 | This variable encodes the prototype of crypt_r. |
| 370 | It is zero if d_crypt_r is undef, and one of the |
| 371 | REENTRANT_PROTO_T_ABC macros of reentr.h if d_crypt_r |
| 372 | is defined. |
| 373 | |
| 374 | cryptlib (d_crypt.U): |
| 375 | This variable holds -lcrypt or the path to a libcrypt.a archive if |

| 377 | up to the Makefile to use this. |
| 378 | |
| 379 | csh (Loc.U): |
| 380 | This variable is used internally by Configure to determine the |
| 381 | full pathname (if any) of the csh program. After Configure runs, |

| 897 | that pass sprintf-%g-like behaviour tests. If perl is using |
| 898 | long doubles, the macro uses the first of the following |
| 899 | functions that pass Configure's tests: qgcvt, sprintf (if |
| 900 | Configure knows how to make sprintf format long doubles--see |
| 901 | sPRIgldbl), gconvert, gcvt, and sprintf (casting to double). |
| 902 | The gconvert_preference and gconvert_ld_preference variables |

| 909 | specific function. If this function expects a double, a |
| 910 | different value may need to be set by the uselongdouble.cbu |
| 911 | call-back unit so that long doubles can be formatted without |
| 912 | loss of precision. |

| 3360 | the list are separated by spaces. This is only useful |
| 3361 | if you have a perl library directory tree structured like the |
| 3362 | default one. See INSTALL for how this works. The versioned |
| 3363 | site_perl directory was introduced in 5.005, so that is the |
| 3364 | lowest possible value. |
| 3365 | |
| 3366 | This list includes architecture-dependent directories back to |
| 3367 | version $api_versionstring (e.g. 5.5.640) and |
| 3368 | architecture-independent directories all the way back to |
| 3369 | 5.005. |
| 3370 | |
| 3371 | inc_version_list_init (inc_version_list.U): |
| 3372 | This variable holds the same list as inc_version_list, but |
| 3373 | each item is enclosed in double quotes and separated by commas, |
| 3374 | suitable for use in the PERL_INC_VERSION_LIST initialization. |
| 3375 | |
| 3376 | incpath (usrinc.U): |
| 3377 | This variable must precede the normal include path to get the |
| 3378 | right one, as in "$incpath/usr/include" or "$incpath/usr/lib". |
| 3379 | Value can be "" or "/bsd43" on mips. |
| 3380 | |
| 3381 | inews (Loc.U): |
| 3382 | This variable is defined but not used by Configure. |
| 3383 | The value is the empty string and is not useful. |
| 3384 | |
| 3385 | initialinstalllocation (bin.U): |
| 3386 | When userelocatableinc is true, this variable holds the location |
| 3387 | that make install should copy the perl binary to, with all the |
| 3388 | run-time relocatable paths calculated from this at install time. |
| 3389 | When used, it is initialised to the original value of binexp, and |
| 3390 | then binexp is set to '.../', as the other binaries are found |
| 3391 | relative to the perl binary. |
| 3392 | |
| 3393 | installarchlib (archlib.U): |
| 3394 | This variable is really the same as archlibexp but may differ on |
| 3395 | those systems using AFS. For extra portability, only this variable |
| 3396 | should be used in makefiles. |
| 3397 | |
| 3398 | installbin (bin.U): |
| 3399 | This variable is the same as binexp unless AFS is running in which case |
| 3400 | the user is explicitly prompted for it. This variable should always |
| 3401 | be used in your makefiles for maximum portability. |
| 3402 | |
| 3403 | installhtml1dir (html1dir.U): |
| 3404 | This variable is really the same as html1direxp, unless you are |
| 3405 | using a different installprefix. For extra portability, you |
| 3406 | should only use this variable within your makefiles. |
| 3407 | |
| 3408 | installhtml3dir (html3dir.U): |
| 3409 | This variable is really the same as html3direxp, unless you are |
| 3410 | using a different installprefix. For extra portability, you |
| 3411 | should only use this variable within your makefiles. |
| 3412 | |
| 3413 | installman1dir (man1dir.U): |
| 3414 | This variable is really the same as man1direxp, unless you are using |
| 3415 | AFS in which case it points to the read/write location whereas |
| 3416 | man1direxp only points to the read-only access location. For extra |
| 3417 | portability, you should only use this variable within your makefiles. |
| 3418 | |
| 3419 | installman3dir (man3dir.U): |
| 3420 | This variable is really the same as man3direxp, unless you are using |
| 3421 | AFS in which case it points to the read/write location whereas |
| 3422 | man3direxp only points to the read-only access location. For extra |
| 3423 | portability, you should only use this variable within your makefiles. |
| 3424 | |
| 3425 | installprefix (installprefix.U): |
| 3426 | This variable holds the name of the directory below which |
| 3427 | "make install" will install the package. For most users, this |
| 3428 | is the same as prefix. However, it is useful for |
| 3429 | installing the software into a different (usually temporary) |
| 3430 | location after which it can be bundled up and moved somehow |
| 3431 | to the final location specified by prefix. |
| 3432 | |
| 3433 | installprefixexp (installprefix.U): |
| 3434 | This variable holds the full absolute path of installprefix |
| 3435 | with all ~-expansion done. |
| 3436 | |
| 3437 | installprivlib (privlib.U): |
| 3438 | This variable is really the same as privlibexp but may differ on |
| 3439 | those systems using AFS. For extra portability, only this variable |
| 3440 | should be used in makefiles. |
| 3441 | |
| 3442 | installscript (scriptdir.U): |
| 3443 | This variable is usually the same as scriptdirexp, unless you are on |
| 3444 | a system running AFS, in which case they may differ slightly. You |
| 3445 | should always use this variable within your makefiles for portability. |
| 3446 | |
| 3447 | installsitearch (sitearch.U): |
| 3448 | This variable is really the same as sitearchexp but may differ on |
| 3449 | those systems using AFS. For extra portability, only this variable |
| 3450 | should be used in makefiles. |
| 3451 | |
| 3452 | installsitebin (sitebin.U): |
| 3453 | This variable is usually the same as sitebinexp, unless you are on |
| 3454 | a system running AFS, in which case they may differ slightly. You |
| 3455 | should always use this variable within your makefiles for portability. |
| 3456 | |
| 3457 | installsitehtml1dir (sitehtml1dir.U): |
| 3458 | This variable is really the same as sitehtml1direxp, unless you are using |
| 3459 | AFS in which case it points to the read/write location whereas |
| 3460 | html1direxp only points to the read-only access location. For extra |
| 3461 | portability, you should only use this variable within your makefiles. |
| 3462 | |
| 3463 | installsitehtml3dir (sitehtml3dir.U): |
| 3464 | This variable is really the same as sitehtml3direxp, unless you are using |
| 3465 | AFS in which case it points to the read/write location whereas |
| 3466 | html3direxp only points to the read-only access location. For extra |
| 3467 | portability, you should only use this variable within your makefiles. |
| 3468 | |
| 3469 | installsitelib (sitelib.U): |
| 3470 | This variable is really the same as sitelibexp but may differ on |
| 3471 | those systems using AFS. For extra portability, only this variable |
| 3472 | should be used in makefiles. |
| 3473 | |
| 3474 | installsiteman1dir (siteman1dir.U): |
| 3475 | This variable is really the same as siteman1direxp, unless you are using |
| 3476 | AFS in which case it points to the read/write location whereas |
| 3477 | man1direxp only points to the read-only access location. For extra |
| 3478 | portability, you should only use this variable within your makefiles. |
| 3479 | |
| 3480 | installsiteman3dir (siteman3dir.U): |
| 3481 | This variable is really the same as siteman3direxp, unless you are using |
| 3482 | AFS in which case it points to the read/write location whereas |
| 3483 | man3direxp only points to the read-only access location. For extra |
| 3484 | portability, you should only use this variable within your makefiles. |
| 3485 | |
| 3486 | installsitescript (sitescript.U): |
| 3487 | This variable is usually the same as sitescriptexp, unless you are on |
| 3488 | a system running AFS, in which case they may differ slightly. You |
| 3489 | should always use this variable within your makefiles for portability. |
| 3490 | |
| 3491 | installstyle (installstyle.U): |
| 3492 | This variable describes the "style" of the perl installation. |
| 3493 | This is intended to be useful for tools that need to |
| 3494 | manipulate entire perl distributions. Perl itself doesn't use |
| 3495 | this to find its libraries -- the library directories are |
| 3496 | stored directly in Config.pm. Currently, there are only two |
| 3497 | styles: "lib" and "lib/perl5". The default library locations |
| 3498 | (e.g. privlib, sitelib) are either $prefix/lib or |
| 3499 | $prefix/lib/perl5. The former is useful if $prefix is a |
| 3500 | directory dedicated to perl (e.g. /opt/perl), while the latter |
| 3501 | is useful if $prefix is shared by many packages, e.g. if |
| 3502 | $prefix=/usr/local. |
| 3503 | |
| 3504 | Unfortunately, while this "style" variable is used to set |
| 3505 | defaults for all three directory hierarchies (core, vendor, and |
| 3506 | site), there is no guarantee that the same style is actually |
| 3507 | appropriate for all those directories. For example, $prefix |
| 3508 | might be /opt/perl, but $siteprefix might be /usr/local. |
| 3509 | (Perhaps, in retrospect, the "lib" style should never have been |
| 3510 | supported, but it did seem like a nice idea at the time.) |
| 3511 | |
| 3512 | The situation is even less clear for tools such as MakeMaker |
| 3513 | that can be used to install additional modules into |
| 3514 | non-standard places. For example, if a user intends to install |
| 3515 | a module into a private directory (perhaps by setting PREFIX on |
| 3516 | the Makefile.PL command line), then there is no reason to |
| 3517 | assume that the Configure-time $installstyle setting will be |
| 3518 | relevant for that PREFIX. |
| 3519 | |
| 3520 | This may later be extended to include other information, so |
| 3521 | be careful with pattern-matching on the results. |
| 3522 | |
| 3523 | For compatibility with perl5.005 and earlier, the default |
| 3524 | setting is based on whether or not $prefix contains the string |
| 3525 | "perl". |
| 3526 | |
| 3527 | installusrbinperl (instubperl.U): |
| 3528 | This variable tells whether Perl should be installed also as |
| 3529 | /usr/bin/perl in addition to |
| 3530 | $installbin/perl |
| 3531 | |
| 3532 | installvendorarch (vendorarch.U): |
| 3533 | This variable is really the same as vendorarchexp but may differ on |
| 3534 | those systems using AFS. For extra portability, only this variable |
| 3535 | should be used in makefiles. |
| 3536 | |
| 3537 | installvendorbin (vendorbin.U): |
| 3538 | This variable is really the same as vendorbinexp but may differ on |

| 3568 | This variable is really the same as vendorscriptexp but may differ on |
| 3569 | those systems using AFS. For extra portability, only this variable |

| 3593 | the package. |
| 3594 | |
| 3595 | ksh (Loc.U): |
| 3596 | This variable is defined but not used by Configure. |
| 3597 | The value is the empty string and is not useful. |
| 3598 | |
| 3599 | ld (dlsrc.U): |
| 3600 | This variable indicates the program to be used to link |
| 3601 | libraries for dynamic loading. On some systems, it is 'ld'. |
| 3602 | On ELF systems, it should be $cc. Mostly, we'll try to respect |
| 3603 | the hint file setting. |
| 3604 | |
| 3605 | lddlflags (dlsrc.U): |
| 3606 | This variable contains any special flags that might need to be |
| 3607 | passed to $ld to create a shared library suitable for dynamic |
| 3608 | loading. It is up to the makefile to use it. For hpux, it |
| 3609 | should be '-b'. For sunos 4.1, it is empty. |
| 3610 | |

| 3620 | This variable holds the name of the shared library |
| 3621 | search path, often LD_LIBRARY_PATH. To get an empty |
| 3622 | string, the hints file must set this to 'none'. |
| 3623 | |
| 3624 | less (Loc.U): |
| 3625 | This variable is used internally by Configure to determine the |
| 3626 | full pathname (if any) of the less program. After Configure runs, |

| 3628 | |
| 3629 | lib_ext (Unix.U): |
| 3630 | This is an old synonym for _a. |
| 3631 | |

| 3637 | libperl, any static extensions (usually just DynaLoader), |
| 3638 | and any other libraries needed on this system. libperl |
| 3639 | is usually libperl.a, but can also be libperl.so.xxx if |
| 3640 | the user wishes to build a perl executable with a shared |
| 3641 | library. |
| 3642 | |
| 3643 | libpth (libpth.U): |
| 3644 | This variable holds the general path (space-separated) used to find |

| 3646 | |
| 3647 | libs (libs.U): |
| 3648 | This variable holds the additional libraries we want to use. |
| 3649 | It is up to the Makefile to deal with it. The list can be empty. |
| 3650 | |
| 3651 | libsdirs (libs.U): |
| 3652 | This variable holds the directory names aka dirnames of the libraries |
| 3653 | we found and accepted, duplicates are removed. |

| 3669 | ahead of ucb or bsd libraries for SVR4. |
| 3670 | |
| 3671 | libswanted_uselargefiles (uselfs.U): |
| 3672 | This variable contains the libraries needed by large file builds |
| 3673 | and added to ldflags by hints files. It is a space separated list |
| 3674 | of the library names without the "lib" prefix or any suffix, just |
| 3675 | like libswanted.. |
| 3676 | |
| 3677 | line (Loc.U): |
| 3678 | This variable is defined but not used by Configure. |
| 3679 | The value is the empty string and is not useful. |
| 3680 | |

| 3688 | |
| 3689 | ln (Loc.U): |
| 3690 | This variable is used internally by Configure to determine the |
| 3691 | full pathname (if any) of the ln program. After Configure runs, |

| 3700 | This variable encodes the prototype of localtime_r. |
| 3701 | It is zero if d_localtime_r is undef, and one of the |
| 3702 | REENTRANT_PROTO_T_ABC macros of reentr.h if d_localtime_r |
| 3703 | is defined. |
| 3704 | |
| 3705 | locincpth (ccflags.U): |
| 3706 | This variable contains a list of additional directories to be |
| 3707 | searched by the compiler. The appropriate '-I' directives will |
| 3708 | be added to ccflags. This is intended to simplify setting |
| 3709 | local directories from the Configure command line. |
| 3710 | It's not much, but it parallels the loclibpth stuff in libpth.U. |
| 3711 | |
| 3712 | loclibpth (libpth.U): |
| 3713 | This variable holds the paths (space-separated) used to find local |
| 3714 | libraries. It is prepended to libpth, and is intended to be easily |
| 3715 | set from the command line. |
| 3716 | |
| 3717 | longdblsize (d_longdbl.U): |
| 3718 | This variable contains the value of the LONG_DOUBLESIZE symbol, which |
| 3719 | indicates to the C program how many bytes there are in a long double, |
| 3720 | if this system supports long doubles. |
| 3721 | |
| 3722 | longlongsize (d_longlong.U): |
| 3723 | This variable contains the value of the LONGLONGSIZE symbol, which |
| 3724 | indicates to the C program how many bytes there are in a long long, |
| 3725 | if this system supports long long. |
| 3726 | |
| 3727 | longsize (intsize.U): |

| 3737 | The value is the empty string and is not useful. |
| 3738 | |
| 3739 | ls (Loc.U): |
| 3740 | This variable is used internally by Configure to determine the |
| 3741 | full pathname (if any) of the ls program. After Configure runs, |
| 3742 | the value is reset to a plain "ls" and is not useful. |
| 3743 | |
| 3744 | lseeksize (lseektype.U): |
| 3745 | This variable defines lseektype to be something like off_t, long, |
| 3746 | or whatever type is used to declare lseek offset's type in the |
| 3747 | kernel (which also appears to be lseek's return type). |
| 3748 | |
| 3749 | lseektype (lseektype.U): |
| 3750 | This variable defines lseektype to be something like off_t, long, |
| 3751 | or whatever type is used to declare lseek offset's type in the |
| 3752 | kernel (which also appears to be lseek's return type). |
| 3753 | |
| 3754 | mad (mad.U): |
| 3755 | This variable indicates that the Misc Attribute Definition code is to |
| 3756 | be compiled. |
| 3757 | |
| 3758 | madlyh (mad.U): |
| 3759 | If the Misc Attribute Decoration is to be compiled, this variable is |
| 3760 | set to the name of the extra header files to be used, else it is '' |
| 3761 | |
| 3762 | madlyobj (mad.U): |
| 3763 | If the Misc Attribute Decoration is to be compiled, this variable is |
| 3764 | set to the name of the extra object files to be used, else it is '' |

| 3766 | madlysrc (mad.U): |
| 3767 | If the Misc Attribute Decoration is to be compiled, this variable is |

| 3776 | The value is the empty string and is not useful. |
| 3777 | |
| 3778 | make (Loc.U): |
| 3779 | This variable is used internally by Configure to determine the |
| 3780 | full pathname (if any) of the make program. After Configure runs, |
| 3781 | the value is reset to a plain "make" and is not useful. |
| 3782 | |
| 3783 | make_set_make (make.U): |
| 3784 | Some versions of 'make' set the variable MAKE. Others do not. |
| 3785 | This variable contains the string to be included in Makefile.SH |
| 3786 | so that MAKE is set if needed, and not if not needed. |
| 3787 | Possible values are: |
| 3788 | |
| 3789 | make_set_make='#' # If your make program handles this for you, |
| 3790 | |
| 3791 | make_set_make="MAKE=$make" # if it doesn't. |
| 3792 | |
| 3793 | This uses a comment character so that we can distinguish a |
| 3794 | 'set' value (from a previous config.sh or Configure '-D' option) |
| 3795 | from an uncomputed value. |
| 3796 | |
| 3797 | mallocobj (mallocsrc.U): |
| 3798 | This variable contains the name of the malloc.o that this package |
| 3799 | generates, if that malloc.o is preferred over the system malloc. |
| 3800 | Otherwise the value is null. This variable is intended for generating |
| 3801 | Makefiles. See mallocsrc. |
| 3802 | |
| 3803 | mallocsrc (mallocsrc.U): |
| 3804 | This variable contains the name of the malloc.c that comes with |
| 3805 | the package, if that malloc.c is preferred over the system malloc. |
| 3806 | Otherwise the value is null. This variable is intended for generating |
| 3807 | Makefiles. |
| 3808 | |
| 3809 | malloctype (mallocsrc.U): |
| 3810 | This variable contains the kind of ptr returned by malloc and realloc. |
| 3811 | |
| 3812 | man1dir (man1dir.U): |
| 3813 | This variable contains the name of the directory in which manual |
| 3814 | source pages are to be put. It is the responsibility of the |
| 3815 | Makefile.SH to get the value of this into the proper command. |
| 3816 | You must be prepared to do the ~name expansion yourself. |
| 3817 | |
| 3818 | man1direxp (man1dir.U): |
| 3819 | This variable is the same as the man1dir variable, but is filename |
| 3820 | expanded at configuration time, for convenient use in makefiles. |
| 3821 | |
| 3822 | man1ext (man1dir.U): |
| 3823 | This variable contains the extension that the manual page should |
| 3824 | have: one of 'n', 'l', or '1'. The Makefile must supply the '.'. |
| 3825 | See man1dir. |
| 3826 | |
| 3827 | man3dir (man3dir.U): |
| 3828 | This variable contains the name of the directory in which manual |
| 3829 | source pages are to be put. It is the responsibility of the |
| 3830 | Makefile.SH to get the value of this into the proper command. |
| 3831 | You must be prepared to do the ~name expansion yourself. |
| 3832 | |
| 3833 | man3direxp (man3dir.U): |
| 3834 | This variable is the same as the man3dir variable, but is filename |
| 3835 | expanded at configuration time, for convenient use in makefiles. |
| 3836 | |
| 3837 | man3ext (man3dir.U): |
| 3838 | This variable contains the extension that the manual page should |
| 3839 | have: one of 'n', 'l', or '3'. The Makefile must supply the '.'. |
| 3840 | See man3dir. |
| 3841 | |
| 3842 | mips_type (usrinc.U): |
| 3843 | This variable holds the environment type for the mips system. |
| 3844 | Possible values are "BSD 4.3" and "System V". |
| 3845 | |
| 3846 | mistrustnm (Csym.U): |
| 3847 | This variable can be used to establish a fallthrough for the cases |
| 3848 | where nm fails to find a symbol. If usenm is false or usenm is true |
| 3849 | and mistrustnm is false, this variable has no effect. If usenm is true |
| 3850 | and mistrustnm is "compile", a test program will be compiled to try to |
| 3851 | find any symbol that can't be located via nm lookup. If mistrustnm is |
| 3852 | "run", the test program will be run as well as being compiled. |
| 3853 | |
| 3854 | mkdir (Loc.U): |
| 3855 | This variable is used internally by Configure to determine the |
| 3856 | full pathname (if any) of the mkdir program. After Configure runs, |
| 3857 | the value is reset to a plain "mkdir" and is not useful. |
| 3858 | |
| 3859 | mmaptype (d_mmap.U): |
| 3860 | This symbol contains the type of pointer returned by mmap() |
| 3861 | (and simultaneously the type of the first argument). |
| 3862 | It can be 'void *' or 'caddr_t'. |
| 3863 | |
| 3864 | modetype (modetype.U): |
| 3865 | This variable defines modetype to be something like mode_t, |
| 3866 | int, unsigned short, or whatever type is used to declare file |
| 3867 | modes for system calls. |
| 3868 | |
| 3869 | more (Loc.U): |
| 3870 | This variable is used internally by Configure to determine the |
| 3871 | full pathname (if any) of the more program. After Configure runs, |
| 3872 | the value is reset to a plain "more" and is not useful. |
| 3873 | |
| 3874 | multiarch (multiarch.U): |
| 3875 | This variable conditionally defines the MULTIARCH symbol |
| 3876 | which signifies the presence of multiplatform files. |
| 3877 | This is normally set by hints files. |
| 3878 | |
| 3879 | mv (Loc.U): |
| 3880 | This variable is defined but not used by Configure. |
| 3881 | The value is the empty string and is not useful. |
| 3882 | |
| 3883 | myarchname (archname.U): |
| 3884 | This variable holds the architecture name computed by Configure in |
| 3885 | a previous run. It is not intended to be perused by any user and |
| 3886 | should never be set in a hint file. |
| 3887 | |
| 3888 | mydomain (myhostname.U): |
| 3889 | This variable contains the eventual value of the MYDOMAIN symbol, |
| 3890 | which is the domain of the host the program is going to run on. |
| 3891 | The domain must be appended to myhostname to form a complete host name. |
| 3892 | The dot comes with mydomain, and need not be supplied by the program. |
| 3893 | |
| 3894 | myhostname (myhostname.U): |
| 3895 | This variable contains the eventual value of the MYHOSTNAME symbol, |
| 3896 | which is the name of the host the program is going to run on. |
| 3897 | The domain is not kept with hostname, but must be gotten from mydomain. |
| 3898 | The dot comes with mydomain, and need not be supplied by the program. |
| 3899 | |
| 3900 | myuname (Oldconfig.U): |
| 3901 | The output of 'uname -a' if available, otherwise the hostname. On Xenix, |
| 3902 | pseudo variables assignments in the output are stripped, thank you. The |
| 3903 | whole thing is then lower-cased. |
| 3904 | |
| 3905 | n (n.U): |
| 3906 | This variable contains the '-n' flag if that is what causes the echo |
| 3907 | command to suppress newline. Otherwise it is null. Correct usage is |
| 3908 | $echo $n "prompt for a question: $c". |
| 3909 | |
| 3910 | need_va_copy (need_va_copy.U): |
| 3911 | This symbol, if defined, indicates that the system stores |
| 3912 | the variable argument list datatype, va_list, in a format |
| 3913 | that cannot be copied by simple assignment, so that some |
| 3914 | other means must be used when copying is required. |
| 3915 | As such systems vary in their provision (or non-provision) |
| 3916 | of copying mechanisms, handy.h defines a platform- |
| 3917 | independent macro, Perl_va_copy(src, dst), to do the job. |
| 3918 | |
| 3919 | netdb_hlen_type (netdbtype.U): |
| 3920 | This variable holds the type used for the 2nd argument to |
| 3921 | gethostbyaddr(). Usually, this is int or size_t or unsigned. |
| 3922 | This is only useful if you have gethostbyaddr(), naturally. |
| 3923 | |
| 3924 | netdb_host_type (netdbtype.U): |
| 3925 | This variable holds the type used for the 1st argument to |
| 3926 | gethostbyaddr(). Usually, this is char * or void *, possibly |
| 3927 | with or without a const prefix. |
| 3928 | This is only useful if you have gethostbyaddr(), naturally. |
| 3929 | |
| 3930 | netdb_name_type (netdbtype.U): |
| 3931 | This variable holds the type used for the argument to |
| 3932 | gethostbyname(). Usually, this is char * or const char *. |
| 3933 | This is only useful if you have gethostbyname(), naturally. |
| 3934 | |
| 3935 | netdb_net_type (netdbtype.U): |
| 3936 | This variable holds the type used for the 1st argument to |
| 3937 | getnetbyaddr(). Usually, this is int or long. |
| 3938 | This is only useful if you have getnetbyaddr(), naturally. |
| 3939 | |
| 3940 | nm (Loc.U): |
| 3941 | This variable is used internally by Configure to determine the |
| 3942 | full pathname (if any) of the nm program. After Configure runs, |
| 3943 | the value is reset to a plain "nm" and is not useful. |
| 3944 | |
| 3945 | nm_opt (usenm.U): |
| 3946 | This variable holds the options that may be necessary for nm. |
| 3947 | |
| 3948 | nm_so_opt (usenm.U): |
| 3949 | This variable holds the options that may be necessary for nm |
| 3950 | to work on a shared library but that can not be used on an |
| 3951 | archive library. Currently, this is only used by Linux, where |
| 3952 | nm --dynamic is *required* to get symbols from an ELF library which |
| 3953 | has been stripped, but nm --dynamic is *fatal* on an archive library. |
| 3954 | Maybe Linux should just always set usenm=false. |
| 3955 | |
| 3956 | nonxs_ext (Extensions.U): |
| 3957 | This variable holds a list of all non-xs extensions included |
| 3958 | in the package. All of them will be built. |
| 3959 | |
| 3960 | nroff (Loc.U): |
| 3961 | This variable is used internally by Configure to determine the |
| 3962 | full pathname (if any) of the nroff program. After Configure runs, |
| 3963 | the value is reset to a plain "nroff" and is not useful. |
| 3964 | |
| 3965 | nv_overflows_integers_at (perlxv.U): |
| 3966 | This variable gives the largest integer value that NVs can hold |
| 3967 | as a constant floating point expression. |

| 3995 | This variable contains the format string used for printing |
| 3996 | a Perl NV using %G-ish floating point format. |
| 3997 | |
| 3998 | nvsize (perlxv.U): |
| 3999 | This variable is the size of an NV in bytes. |
| 4000 | |
| 4001 | nvtype (perlxv.U): |
| 4002 | This variable contains the C type used for Perl's NV. |
| 4003 | |
| 4004 | o_nonblock (nblock_io.U): |
| 4005 | This variable bears the symbol value to be used during open() or fcntl() |
| 4006 | to turn on non-blocking I/O for a file descriptor. If you wish to switch |
| 4007 | between blocking and non-blocking, you may try ioctl(FIOSNBIO) instead, |
| 4008 | but that is only supported by some devices. |
| 4009 | |
| 4010 | obj_ext (Unix.U): |
| 4011 | This is an old synonym for _o. |
| 4012 | |
| 4013 | old_pthread_create_joinable (d_pthrattrj.U): |
| 4014 | This variable defines the constant to use for creating joinable |
| 4015 | (aka undetached) pthreads. Unused if pthread.h defines |
| 4016 | PTHREAD_CREATE_JOINABLE. If used, possible values are |
| 4017 | PTHREAD_CREATE_UNDETACHED and __UNDETACHED. |
| 4018 | |
| 4019 | optimize (ccflags.U): |
| 4020 | This variable contains any optimizer/debugger flag that should be used. |
| 4021 | It is up to the Makefile to use it. |
| 4022 | |
| 4023 | orderlib (orderlib.U): |
| 4024 | This variable is "true" if the components of libraries must be ordered |
| 4025 | (with `lorder $* | tsort`) before placing them in an archive. Set to |
| 4026 | "false" if ranlib or ar can generate random libraries. |
| 4027 | |
| 4028 | osname (Oldconfig.U): |
| 4029 | This variable contains the operating system name (e.g. sunos, |
| 4030 | solaris, hpux, etc.). It can be useful later on for setting |
| 4031 | defaults. Any spaces are replaced with underscores. It is set |
| 4032 | to a null string if we can't figure it out. |
| 4033 | |
| 4034 | osvers (Oldconfig.U): |
| 4035 | This variable contains the operating system version (e.g. |
| 4036 | 4.1.3, 5.2, etc.). It is primarily used for helping select |
| 4037 | an appropriate hints file, but might be useful elsewhere for |
| 4038 | setting defaults. It is set to '' if we can't figure it out. |
| 4039 | We try to be flexible about how much of the version number |
| 4040 | to keep, e.g. if 4.1.1, 4.1.2, and 4.1.3 are essentially the |
| 4041 | same for this package, hints files might just be os_4.0 or |
| 4042 | os_4.1, etc., not keeping separate files for each little release. |
| 4043 | |
| 4044 | otherlibdirs (otherlibdirs.U): |
| 4045 | This variable contains a colon-separated set of paths for the perl |
| 4046 | binary to search for additional library files or modules. |
| 4047 | These directories will be tacked to the end of @INC. |
| 4048 | Perl will automatically search below each path for version- |
| 4049 | and architecture-specific directories. See inc_version_list |
| 4050 | for more details. |
| 4051 | A value of ' ' means 'none' and is used to preserve this value |
| 4052 | for the next run through Configure. |
| 4053 | |
| 4054 | package (package.U): |
| 4055 | This variable contains the name of the package being constructed. |
| 4056 | It is primarily intended for the use of later Configure units. |
| 4057 | |
| 4058 | pager (pager.U): |
| 4059 | This variable contains the name of the preferred pager on the system. |
| 4060 | Usual values are (the full pathnames of) more, less, pg, or cat. |
| 4061 | |
| 4062 | passcat (nis.U): |
| 4063 | This variable contains a command that produces the text of the |
| 4064 | /etc/passwd file. This is normally "cat /etc/passwd", but can be |
| 4065 | "ypcat passwd" when NIS is used. |
| 4066 | On some systems, such as os390, there may be no equivalent |
| 4067 | command, in which case this variable is unset. |
| 4068 | |
| 4069 | patchlevel (patchlevel.U): |
| 4070 | The patchlevel level of this package. |
| 4071 | The value of patchlevel comes from the patchlevel.h file. |
| 4072 | In a version number such as 5.6.1, this is the "6". |
| 4073 | In patchlevel.h, this is referred to as "PERL_VERSION". |
| 4074 | |
| 4075 | path_sep (Unix.U): |

| 4077 | used to separate elements in the command shell search PATH. |
| 4078 | |
| 4079 | perl (Loc.U): |
| 4080 | This variable is used internally by Configure to determine the |

| 4084 | perl5 (perl5.U): |
| 4085 | This variable contains the full path (if any) to a previously |
| 4086 | installed perl5.005 or later suitable for running the script |
| 4087 | to determine inc_version_list. |
| 4088 | |
| 4089 | PERL_API_REVISION (patchlevel.h): |
| 4090 | This number describes the earliest compatible PERL_REVISION of |
| 4091 | Perl ("compatibility" here being defined as sufficient binary/API |
| 4092 | compatibility to run XS code built with the older version). |
| 4093 | Normally this does not change across maintenance releases. |
| 4094 | Please read the comment in patchlevel.h. |
| 4095 | |
| 4096 | PERL_API_SUBVERSION (patchlevel.h): |
| 4097 | This number describes the earliest compatible PERL_SUBVERSION of |
| 4098 | Perl ("compatibility" here being defined as sufficient binary/API |

| 4100 | Normally this does not change across maintenance releases. |
| 4101 | Please read the comment in patchlevel.h. |
| 4102 | |
| 4103 | PERL_API_VERSION (patchlevel.h): |
| 4104 | This number describes the earliest compatible PERL_VERSION of |
| 4105 | Perl ("compatibility" here being defined as sufficient binary/API |
| 4106 | compatibility to run XS code built with the older version). |
| 4107 | Normally this does not change across maintenance releases. |
| 4108 | Please read the comment in patchlevel.h. |
| 4109 | |
| 4110 | PERL_CONFIG_SH (Oldsyms.U): |
| 4111 | This is set to 'true' in config.sh so that a shell script |
| 4112 | sourcing config.sh can tell if it has been sourced already. |
| 4113 | |
| 4114 | PERL_PATCHLEVEL (Oldsyms.U): |
| 4115 | This symbol reflects the patchlevel, if available. Will usually |
| 4116 | come from the .patch file, which is available when the perl |
| 4117 | source tree was fetched with rsync. |
| 4118 | |
| 4119 | perl_patchlevel (patchlevel.U): |
| 4120 | This is the Perl patch level, a numeric change identifier, |
| 4121 | as defined by whichever source code maintenance system |
| 4122 | is used to maintain the patches; currently Perforce. |
| 4123 | It does not correlate with the Perl version numbers or |
| 4124 | the maintenance versus development dichotomy except |
| 4125 | by also being increasing. |
| 4126 | |
| 4127 | PERL_REVISION (Oldsyms.U): |
| 4128 | In a Perl version number such as 5.6.2, this is the 5. |
| 4129 | This value is manually set in patchlevel.h |
| 4130 | |
| 4131 | perl_static_inline (d_static_inline.U): |
| 4132 | This variable defines the PERL_STATIC_INLINE symbol to |
| 4133 | the best-guess incantation to use for static inline functions. |
| 4134 | Possibilities include |
| 4135 | static inline (c99) |

| 4137 | static __inline (MSVC) |
| 4138 | static _inline (older MSVC) |
| 4139 | static (c89 compilers) |
| 4140 | |
| 4141 | PERL_SUBVERSION (Oldsyms.U): |
| 4142 | In a Perl version number such as 5.6.2, this is the 2. |
| 4143 | Values greater than 50 represent potentially unstable |
| 4144 | development subversions. |
| 4145 | This value is manually set in patchlevel.h |
| 4146 | |
| 4147 | PERL_VERSION (Oldsyms.U): |
| 4148 | In a Perl version number such as 5.6.2, this is the 6. |
| 4149 | This value is manually set in patchlevel.h |

| 4156 | by extensions only will by dropped, if using dynamic loading). |
| 4157 | |
| 4158 | perlpath (perlpath.U): |
| 4159 | This variable contains the eventual value of the PERLPATH symbol, |
| 4160 | which contains the name of the perl interpreter to be used in |
| 4161 | shell scripts and in the "eval 'exec'" idiom. This variable is |
| 4162 | not necessarily the pathname of the file containing the perl |
| 4163 | interpreter; you must append the executable extension (_exe) if |
| 4164 | it is not already present. Note that Perl code that runs during |
| 4165 | the Perl build process cannot reference this variable, as Perl |
| 4166 | may not have been installed, or even if installed, may be a |
| 4167 | different version of Perl. |
| 4168 | |
| 4169 | pg (Loc.U): |
| 4170 | This variable is used internally by Configure to determine the |
| 4171 | full pathname (if any) of the pg program. After Configure runs, |
| 4172 | the value is reset to a plain "pg" and is not useful. |
| 4173 | |
| 4174 | phostname (myhostname.U): |
| 4175 | This variable contains the eventual value of the PHOSTNAME symbol, |
| 4176 | which is a command that can be fed to popen() to get the host name. |
| 4177 | The program should probably not presume that the domain is or isn't |
| 4178 | there already. |
| 4179 | |
| 4180 | pidtype (pidtype.U): |
| 4181 | This variable defines PIDTYPE to be something like pid_t, int, |
| 4182 | ushort, or whatever type is used to declare process ids in the kernel. |
| 4183 | |
| 4184 | plibpth (libpth.U): |
| 4185 | Holds the private path used by Configure to find out the libraries. |
| 4186 | Its value is prepend to libpth. This variable takes care of special |
| 4187 | machines, like the mips. Usually, it should be empty. |
| 4188 | |
| 4189 | pmake (Loc.U): |
| 4190 | This variable is defined but not used by Configure. |
| 4191 | The value is the empty string and is not useful. |
| 4192 | |
| 4193 | pr (Loc.U): |
| 4194 | This variable is defined but not used by Configure. |
| 4195 | The value is the empty string and is not useful. |
| 4196 | |
| 4197 | prefix (prefix.U): |
| 4198 | This variable holds the name of the directory below which the |
| 4199 | user will install the package. Usually, this is /usr/local, and |

| 4212 | this directory while performing installation (with ~ substitution). |
| 4213 | |
| 4214 | privlibexp (privlib.U): |
| 4215 | This variable is the ~name expanded version of privlib, so that you |

| 4263 | rd_nodata (nblock_io.U): |
| 4264 | This variable holds the return code from read() when no data is |
| 4265 | present. It should be -1, but some systems return 0 when O_NDELAY is |

| 4285 | |
| 4286 | rm (Loc.U): |
| 4287 | This variable is used internally by Configure to determine the |

| 4311 | This variable defines the way to yield the execution |
| 4312 | of the current thread. |

| 4314 | scriptdir (scriptdir.U): |
| 4315 | This variable holds the name of the directory in which the user wants |
| 4316 | to put publicly scripts for the package in question. It is either |

| 4336 | That is, if you do select(n, ...), how many bits at least will be |
| 4337 | cleared in the masks if some activity is detected. Usually this |
| 4338 | is either n or 32*ceil(n/32), especially many little-endians do |
| 4339 | the latter. This is only useful if you have select(), naturally. |
| 4340 | |
| 4341 | selecttype (selecttype.U): |
| 4342 | This variable holds the type used for the 2nd, 3rd, and 4th |
| 4343 | arguments to select. Usually, this is 'fd_set *', if HAS_FD_SET |

| 4363 | setlocale_r_proto (d_setlocale_r.U): |
| 4364 | This variable encodes the prototype of setlocale_r. |
| 4365 | It is zero if d_setlocale_r is undef, and one of the |

| 4386 | |
| 4387 | setservent_r_proto (d_setservent_r.U): |
| 4388 | This variable encodes the prototype of setservent_r. |

| 4406 | D:/bin/sh.exe. |
| 4407 | This unit comes before Options.U, so you can't set sh with a '-D' |
| 4408 | option, though you can override this (and startsh) |
| 4409 | with '-O -Dsh=/bin/whatever -Dstartsh=whatever' |
| 4410 | |
| 4411 | shar (Loc.U): |
| 4412 | This variable is defined but not used by Configure. |

| 4428 | If the user builds a shared libperl.so, then we need to tell the |
| 4429 | 'perl' executable where it will be able to find the installed libperl.so. |
| 4430 | One way to do this on some systems is to set the environment variable |
| 4431 | LD_RUN_PATH to the directory that will be the final location of the |
| 4432 | shared libperl.so. The makefile can use this with something like |
| 4433 | $shrpenv $(CC) -o perl perlmain.o $libperl $libs |
| 4434 | Typical values are |
| 4435 | shrpenv="env LD_RUN_PATH=$archlibexp/CORE" |
| 4436 | or |
| 4437 | shrpenv='' |
| 4438 | See the main perl Makefile.SH for actual working usage. |
| 4439 | Alternatively, we might be able to use a command line option such |
| 4440 | as -R $archlibexp/CORE (Solaris) or -Wl,-rpath |

| 5029 | should be used when available. |
| 5030 | |
| 5031 | usemultiplicity (usemultiplicity.U): |
| 5032 | This variable conditionally defines the MULTIPLICITY symbol, |
| 5033 | and indicates that Perl should be built to use multiplicity. |
| 5034 | |
| 5035 | usemymalloc (mallocsrc.U): |
| 5036 | This variable contains y if the malloc that comes with this package |
| 5037 | is desired over the system's version of malloc. People often include |
| 5038 | special versions of malloc for efficiency, but such versions are often |
| 5039 | less portable. See also mallocsrc and mallocobj. |
| 5040 | If this is 'y', then -lmalloc is removed from $libs. |
| 5041 | |
| 5042 | usenm (usenm.U): |
| 5043 | This variable contains 'true' or 'false' depending whether the |
| 5044 | nm extraction is wanted or not. |
| 5045 | |
| 5046 | useopcode (Extensions.U): |
| 5047 | This variable holds either 'true' or 'false' to indicate |
| 5048 | whether the Opcode extension should be used. The sole |
| 5049 | use for this currently is to allow an easy mechanism |
| 5050 | for users to skip the Opcode extension from the Configure |
| 5051 | command line. |
| 5052 | |
| 5053 | useperlio (useperlio.U): |
| 5054 | This variable conditionally defines the USE_PERLIO symbol, |
| 5055 | and indicates that the PerlIO abstraction should be |
| 5056 | used throughout. |
| 5057 | |
| 5058 | useposix (Extensions.U): |
| 5059 | This variable holds either 'true' or 'false' to indicate |
| 5060 | whether the POSIX extension should be used. The sole |
| 5061 | use for this currently is to allow an easy mechanism |
| 5062 | for hints files to indicate that POSIX will not compile |
| 5063 | on a particular system. |
| 5064 | |
| 5065 | usereentrant (usethreads.U): |
| 5066 | This variable conditionally defines the USE_REENTRANT_API symbol, |
| 5067 | which indicates that the thread code may try to use the various |
| 5068 | _r versions of library functions. This is only potentially |
| 5069 | meaningful if usethreads is set and is very experimental, it is |
| 5070 | not even prompted for. |
| 5071 | |
| 5072 | userelocatableinc (bin.U): |
| 5073 | This variable is set to true to indicate that perl should relocate |
| 5074 | @INC entries at runtime based on the path to the perl binary. |
| 5075 | Any @INC paths starting ".../" are relocated relative to the directory |
| 5076 | containing the perl binary, and a logical cleanup of the path is then |
| 5077 | made around the join point (removing "dir/../" pairs) |
| 5078 | |
| 5079 | usesfio (d_sfio.U): |
| 5080 | This variable is set to true when the user agrees to use sfio. |
| 5081 | It is set to false when sfio is not available or when the user |
| 5082 | explicitly requests not to use sfio. It is here primarily so |
| 5083 | that command-line settings can override the auto-detection of |
| 5084 | d_sfio without running into a "WHOA THERE". |
| 5085 | |
| 5086 | useshrplib (libperl.U): |
| 5087 | This variable is set to 'true' if the user wishes |
| 5088 | to build a shared libperl, and 'false' otherwise. |
| 5089 | |
| 5090 | usesitecustomize (d_sitecustomize.U): |
| 5091 | This variable is set to true when the user requires a mechanism that |
| 5092 | allows the sysadmin to add entries to @INC at runtime. This variable |
| 5093 | being set, makes perl run '$sitelib/sitecustomize.pl' at startup. |
| 5094 | |
| 5095 | usesocks (usesocks.U): |
| 5096 | This variable conditionally defines the USE_SOCKS symbol, |
| 5097 | and indicates that Perl should be built to use SOCKS. |
| 5098 | |
| 5099 | usethreads (usethreads.U): |
| 5100 | This variable conditionally defines the USE_THREADS symbol, |
| 5101 | and indicates that Perl should be built to use threads. |
| 5102 | |
| 5103 | usevendorprefix (vendorprefix.U): |
| 5104 | This variable tells whether the vendorprefix |
| 5105 | and consequently other vendor* paths are in use. |
| 5106 | |
| 5107 | usevfork (d_vfork.U): |
| 5108 | This variable is set to true when the user accepts to use vfork. |
| 5109 | It is set to false when no vfork is available or when the user |
| 5110 | explicitly requests not to use vfork. |
| 5111 | |
| 5112 | usrinc (usrinc.U): |
| 5113 | This variable holds the path of the include files, which is |
| 5114 | usually /usr/include. It is mainly used by other Configure units. |
| 5115 | |
| 5116 | uuname (Loc.U): |
| 5117 | This variable is defined but not used by Configure. |
| 5118 | The value is the empty string and is not useful. |
| 5119 | |
| 5120 | uvoformat (perlxvf.U): |
| 5121 | This variable contains the format string used for printing |
| 5122 | a Perl UV as an unsigned octal integer. |
| 5123 | |
| 5124 | uvsize (perlxv.U): |
| 5125 | This variable is the size of a UV in bytes. |
| 5126 | |
| 5127 | uvtype (perlxv.U): |
| 5128 | This variable contains the C type used for Perl's UV. |
| 5129 | |
| 5130 | uvuformat (perlxvf.U): |
| 5131 | This variable contains the format string used for printing |
| 5132 | a Perl UV as an unsigned decimal integer. |
| 5133 | |
| 5134 | uvxformat (perlxvf.U): |
| 5135 | This variable contains the format string used for printing |
| 5136 | a Perl UV as an unsigned hexadecimal integer in lowercase abcdef. |
| 5137 | |
| 5138 | uvXUformat (perlxvf.U): |
| 5139 | This variable contains the format string used for printing |
| 5140 | a Perl UV as an unsigned hexadecimal integer in uppercase ABCDEF. |
| 5141 | |
| 5142 | vaproto (vaproto.U): |
| 5143 | This variable conditionally defines CAN_VAPROTO on systems supporting |
| 5144 | prototype declaration of functions with a variable number of |
| 5145 | arguments. See also prototype. |
| 5146 | |
| 5147 | vendorarch (vendorarch.U): |
| 5148 | This variable contains the value of the PERL_VENDORARCH symbol. |
| 5149 | It may have a ~ on the front. |
| 5150 | The standard distribution will put nothing in this directory. |
| 5151 | Vendors who distribute perl may wish to place their own |
| 5152 | architecture-dependent modules and extensions in this directory with |
| 5153 | MakeMaker Makefile.PL INSTALLDIRS=vendor |
| 5154 | or equivalent. See INSTALL for details. |
| 5155 | |
| 5156 | vendorarchexp (vendorarch.U): |
| 5157 | This variable is the ~name expanded version of vendorarch, so that you |
| 5158 | may use it directly in Makefiles or shell scripts. |
| 5159 | |
| 5160 | vendorbin (vendorbin.U): |
| 5161 | This variable contains the eventual value of the VENDORBIN symbol. |
| 5162 | It may have a ~ on the front. |
| 5163 | The standard distribution will put nothing in this directory. |
| 5164 | Vendors who distribute perl may wish to place additional |
| 5165 | binaries in this directory with |

| 5167 | or equivalent. See INSTALL for details. |
| 5168 | |
| 5169 | vendorbinexp (vendorbin.U): |
| 5170 | This variable is the ~name expanded version of vendorbin, so that you |
| 5171 | may use it directly in Makefiles or shell scripts. |
| 5172 | |
| 5173 | vendorhtml1dir (vendorhtml1dir.U): |
| 5174 | This variable contains the name of the directory for html |
| 5175 | pages. It may have a ~ on the front. |
| 5176 | The standard distribution will put nothing in this directory. |
| 5177 | Vendors who distribute perl may wish to place their own |
| 5178 | html pages in this directory with |
| 5179 | MakeMaker Makefile.PL INSTALLDIRS=vendor |
| 5180 | or equivalent. See INSTALL for details. |
| 5181 | |
| 5182 | vendorhtml1direxp (vendorhtml1dir.U): |
| 5183 | This variable is the ~name expanded version of vendorhtml1dir, so that you |
| 5184 | may use it directly in Makefiles or shell scripts. |
| 5185 | |

| 5196 | This variable is the ~name expanded version of vendorhtml3dir, so that you |
| 5197 | may use it directly in Makefiles or shell scripts. |
| 5198 | |
| 5199 | vendorlib (vendorlib.U): |
| 5200 | This variable contains the eventual value of the VENDORLIB symbol, |
| 5201 | which is the name of the private library for this package. |
| 5202 | The standard distribution will put nothing in this directory. |
| 5203 | Vendors who distribute perl may wish to place their own |
| 5204 | modules in this directory with |
| 5205 | MakeMaker Makefile.PL INSTALLDIRS=vendor |
| 5206 | or equivalent. See INSTALL for details. |
| 5207 | |
| 5208 | vendorlib_stem (vendorlib.U): |
| 5209 | This variable is $vendorlibexp with any trailing version-specific component |
| 5210 | removed. The elements in inc_version_list (inc_version_list.U) can |
| 5211 | be tacked onto this variable to generate a list of directories to search. |
| 5212 | |
| 5213 | vendorlibexp (vendorlib.U): |
| 5214 | This variable is the ~name expanded version of vendorlib, so that you |

| 5238 | |
| 5239 | vendorman3direxp (vendorman3dir.U): |
| 5240 | This variable is the ~name expanded version of vendorman3dir, so that you |
| 5241 | may use it directly in Makefiles or shell scripts. |
| 5242 | |
| 5243 | vendorprefix (vendorprefix.U): |
| 5244 | This variable holds the full absolute path of the directory below |
| 5245 | which the vendor will install add-on packages. |
| 5246 | See INSTALL for usage and examples. |
| 5247 | |
| 5248 | vendorprefixexp (vendorprefix.U): |

| 5257 | executable scripts in this directory with |
| 5258 | MakeMaker Makefile.PL INSTALLDIRS=vendor |
| 5259 | or equivalent. See INSTALL for details. |
| 5260 | |
| 5261 | vendorscriptexp (vendorscript.U): |

| 5264 | |
| 5265 | version (patchlevel.U): |
| 5266 | The full version number of this package, such as 5.6.1 (or 5_6_1). |
| 5267 | This combines revision, patchlevel, and subversion to get the |
| 5268 | full version number, including any possible subversions. |
| 5269 | This is suitable for use as a directory name, and hence is |
| 5270 | filesystem dependent. |
| 5271 | |
| 5272 | version_patchlevel_string (patchlevel.U): |
| 5273 | This is a string combining version, subversion and |
| 5274 | perl_patchlevel (if perl_patchlevel is non-zero). |
| 5275 | It is typically something like |
| 5276 | 'version 7 subversion 1' or |
| 5277 | 'version 7 subversion 1 patchlevel 11224' |
| 5278 | It is computed here to avoid duplication of code in myconfig.SH |
| 5279 | and lib/Config.pm. |
| 5280 | |
| 5281 | versiononly (versiononly.U): |
| 5282 | If set, this symbol indicates that only the version-specific |
| 5283 | components of a perl installation should be installed. |
| 5284 | This may be useful for making a test installation of a new |
| 5285 | version without disturbing the existing installation. |
| 5286 | Setting versiononly is equivalent to setting installperl's -v option. |
| 5287 | In particular, the non-versioned scripts and programs such as |
| 5288 | a2p, c2ph, h2xs, pod2*, and perldoc are not installed |
| 5289 | (see INSTALL for a more complete list). Nor are the man |
| 5290 | pages installed. |
| 5291 | Usually, this is undef. |
| 5292 | |
| 5293 | vi (Loc.U): |
| 5294 | This variable is defined but not used by Configure. |
| 5295 | The value is the empty string and is not useful. |
| 5296 | |
| 5297 | voidflags (voidflags.U): |
| 5298 | This variable contains the eventual value of the VOIDFLAGS symbol, |
| 5299 | which indicates how much support of the void type is given by this |
| 5300 | compiler. See VOIDFLAGS for more info. |
| 5301 | |
| 5302 | xlibpth (libpth.U): |
| 5303 | This variable holds extra path (space-separated) used to find |
| 5304 | libraries on this platform, for example CPU-specific libraries |
| 5305 | (on multi-CPU platforms) may be listed here. |
| 5306 | |
| 5307 | yacc (yacc.U): |
| 5308 | This variable holds the name of the compiler compiler we |
| 5309 | want to use in the Makefile. It can be yacc, byacc, or bison -y. |
| 5310 | |
| 5311 | yaccflags (yacc.U): |
| 5312 | This variable contains any additional yacc flags desired by the |
| 5313 | user. It is up to the Makefile to use this. |
| 5314 | |
| 5315 | zcat (Loc.U): |
| 5316 | This variable is defined but not used by Configure. |
| 5317 | The value is the empty string and is not useful. |
| 5318 | |
| 5319 | zip (Loc.U): |
| 5320 | This variable is used internally by Configure to determine the |
| 5321 | full pathname (if any) of the zip program. After Configure runs, |
| 5322 | the value is reset to a plain "zip" and is not useful. |
| 5323 | |
