3 | # If these # comments don't work, trim them. Don't worry about any other | |
4 | # shell scripts, Configure will trim # comments from them for you. | |
5 | # | |
6 | # (If you are trying to port this package to a machine without sh, | |
7 | # I would suggest you have a look at the prototypical config_h.SH file | |
8 | # and edit it to reflect your system. Some packages may include samples | |
9 | # of config.h for certain machines, so you might look for one of those.) | |

11 | # Yes, you may rip this off to use in other distribution packages. This | |
12 | # script belongs to the public domain and cannot be copyrighted. | |
13 | # | |
613d6c3e | 14 | # Note: this Configure script was generated automatically. Rather than |
2304df62 | 15 | # working with this copy of Configure, you may wish to get metaconfig. |
613d6c3e | 16 | # The dist package (which contains metaconfig) is available via SVN: |
7c1269c3 | 17 | # svn co https://svn.code.sf.net/p/dist/code/trunk/dist |

19 | # Though this script was generated by metaconfig from metaunits, it is |
20 | # OK to send patches against Configure itself. It's up to the Configure | |
21 | # pumpkin to backport the patch to the metaunits if it is accepted. | |

24 | # The metaunits are also available from the public git repository: |

37 | SCO csh still thinks true is false. Write to SCO today and tell them that next | |
38 | year Configure ought to "rm /bin/csh" unless they fix their blasted shell. :-) | |

41 | we'd have to do is go in and swap the && and || tokens, wherever they are.) | |

2185 | This is an UNSTABLE DEVELOPMENT release. | |
9507cadf JH |
2186 | The version of this $package distribution is $xversion, that is, odd, |
2187 | (as opposed to even) and that signifies a development release. | |
3d5d58b1 | 2188 | If you want a maintenance release, you want an even-numbered version. |

2189 | |
2190 | Do ***NOT*** install this into production use. | |
2191 | Data corruption and crashes are possible. | |
2192 | ||
2193 | It is most seriously suggested that you do not continue any further | |
2194 | unless you want to help in developing and debugging Perl. | |
2195 | ||

2196 | If you *still* want to build perl, you can answer 'y' now, |

2304df62 | 2247 | This installation shell script will examine your system and ask you questions |
a0d0e21e | 2248 | to determine how the perl5 package should be installed. If you get |
2304df62 AD |
2249 | stuck on a question, you may use a ! shell escape to start a subshell or |
2250 | execute a command. Many of the questions will have default answers in square | |
2251 | brackets; typing carriage return will give you the default. | |
2252 | ||
2253 | On some of the questions which ask for file or directory names you are allowed | |
2254 | to use the ~name construct to specify the login directory belonging to "name", | |
2255 | even if you don't have a shell which knows about that. Questions where this is | |
2256 | allowed will be marked "(~name ok)". | |
2257 | ||

2262 | cat <<'EOH' | |
2263 | ||
2264 | The prompter used in this script allows you to use shell variables and | |
2265 | backticks in your answers. You may use $1, $2, etc... to refer to the words | |
2266 | in the default answer, as if the default line was a set of arguments given to a | |
2267 | script shell. This means you may also use $* to repeat the whole default line, | |
2268 | so you do not have to re-type everything to add something to the default. | |
2269 | ||
cd95ead5 | 2270 | Every time there is a substitution, you will have to confirm. If there is an |
2304df62 AD |
2271 | error (e.g. an unmatched backtick), the default answer will remain unchanged |
2272 | and you will be prompted again. | |
2273 | ||
2274 | If you are in a hurry, you may run 'Configure -d'. This will bypass nearly all | |
2275 | the questions and use the computed defaults (or the previous answers if there | |
2276 | was already a config.sh file). Type 'Configure -h' for a list of options. | |
ecfc5424 | 2277 | You may also start interactively and then answer '& -d' at any prompt to turn |
dfe9444c | 2278 | on the non-interactive behaviour for the remainder of the execution. |

2284 | Much effort has been expended to ensure that this shell script will run on any | |
2285 | Unix system. If despite that it blows up on yours, your best bet is to edit | |
40000a8c AD |
2286 | Configure and run it again. If you can't run Configure for some reason, |
2287 | you'll have to generate a config.sh file by hand. Whatever problems you | |
7f2de2d2 | 2288 | have, let me (perlbug@perl.org) know how I blew it. |
2304df62 AD |
2289 | |
2290 | This installation script affects things in two ways: | |
2291 | ||
2292 | 1) it may do direct variable substitutions on some of the files included | |
2293 | in this kit. | |
2294 | 2) it builds a config.h file for inclusion in C programs. You may edit | |
2295 | any of these files as the need arises after running this script. | |
2296 | ||
2297 | If you make a mistake on a question, there is no easy way to back up to it | |
2298 | currently. The easiest thing to do is to edit config.sh and rerun all the SH | |
2299 | files. Configure will offer to let you do this before it runs the SH files. | |

4487 | ||
4488 | In general it is a good idea to keep gcc synchronized with | |

6921 | The installation process will also create a directory for | |
6922 | vendor-supplied add-ons. Vendors who supply perl with their system | |
6923 | may find it convenient to place all vendor-supplied files in this | |
6924 | directory rather than in the main distribution directory. This will | |
6925 | ease upgrades between binary-compatible maintenance versions of perl. | |
6926 | ||
6927 | Of course you may also use these directories in whatever way you see | |
6928 | fit. For example, you might use them to access modules shared over a | |
6929 | company-wide network. | |
6930 | ||
6931 | The default answer should be fine for most people. | |

7428 | I can use $nm to extract the symbols from your C libraries. This |
7429 | is a time consuming task which may generate huge output on the disk (up | |
7430 | to 3 megabytes) but that should make the symbols extraction faster. The | |
7431 | alternative is to skip the 'nm' extraction part and to compile a small | |
7432 | test program instead to determine whether each symbol is present. If | |
7433 | you have a fast C compiler and/or if your 'nm' output cannot be parsed, | |
7434 | this may be the best solution. | |
b4eb6b3d | 7435 | |
89ce900e | 7436 | You probably shouldn't let me use 'nm' if you are using the GNU C Library. |

8263 | I need to select a good name for the shared libperl. If your system uses | |
8264 | library names with major and minor numbers, then you might want something | |
8265 | like $majmin. Alternatively, if your system uses a single version | |
8266 | number for shared libraries, then you might want to use $majonly. | |
8267 | Or, your system might be quite happy with a simple libperl.$so. | |
8268 | ||
8269 | Since the shared libperl will get installed into a version-specific | |
8270 | architecture-dependent directory, the version number of the shared perl | |
