| 327 | The extension you are trying to build apparently is rather old and |
| 328 | most probably outdated. We detect that from the fact, that a |
| 329 | subroutine "writeMakefile" is called, and this subroutine is not |
| 330 | supported anymore since about October 1994. |
| 331 | |
| 332 | Please contact the author or look into CPAN (details about CPAN can be |
| 333 | found in the FAQ and at http:/www.perl.com) for a more recent version |
| 334 | of the extension. If you're really desperate, you can try to change |
| 335 | the subroutine name from writeMakefile to WriteMakefile and rerun |
| 336 | 'perl Makefile.PL', but you're most probably left alone, when you do |
| 337 | so. |

| 964 | =head1 NAME |
| 965 | |
| 966 | ExtUtils::MakeMaker - Create a module Makefile |
| 967 | |
| 968 | =head1 SYNOPSIS |
| 969 | |
| 970 | use ExtUtils::MakeMaker; |
| 971 | |
| 972 | WriteMakefile( ATTRIBUTE => VALUE [, ...] ); |
| 973 | |
| 974 | =head1 DESCRIPTION |
| 975 | |
| 976 | This utility is designed to write a Makefile for an extension module |
| 977 | from a Makefile.PL. It is based on the Makefile.SH model provided by |
| 978 | Andy Dougherty and the perl5-porters. |
| 979 | |
| 980 | It splits the task of generating the Makefile into several subroutines |
| 981 | that can be individually overridden. Each subroutine returns the text |
| 982 | it wishes to have written to the Makefile. |
| 983 | |
| 984 | MakeMaker is object oriented. Each directory below the current |
| 985 | directory that contains a Makefile.PL is treated as a separate |
| 986 | object. This makes it possible to write an unlimited number of |
| 987 | Makefiles with a single invocation of WriteMakefile(). |
| 988 | |
| 989 | =head2 How To Write A Makefile.PL |
| 990 | |
| 991 | See ExtUtils::MakeMaker::Tutorial. |
| 992 | |
| 993 | The long answer is the rest of the manpage :-) |
| 994 | |
| 995 | =head2 Default Makefile Behaviour |
| 996 | |
| 997 | The generated Makefile enables the user of the extension to invoke |
| 998 | |
| 999 | perl Makefile.PL # optionally "perl Makefile.PL verbose" |
| 1000 | make |
| 1001 | make test # optionally set TEST_VERBOSE=1 |
| 1002 | make install # See below |
| 1003 | |
| 1004 | The Makefile to be produced may be altered by adding arguments of the |
| 1005 | form C<KEY=VALUE>. E.g. |
| 1006 | |
| 1007 | perl Makefile.PL PREFIX=/tmp/myperl5 |
| 1008 | |
| 1009 | Other interesting targets in the generated Makefile are |
| 1010 | |
| 1011 | make config # to check if the Makefile is up-to-date |
| 1012 | make clean # delete local temp files (Makefile gets renamed) |
| 1013 | make realclean # delete derived files (including ./blib) |
| 1014 | make ci # check in all the files in the MANIFEST file |
| 1015 | make dist # see below the Distribution Support section |
| 1016 | |
| 1017 | =head2 make test |
| 1018 | |
| 1019 | MakeMaker checks for the existence of a file named F<test.pl> in the |
| 1020 | current directory and if it exists it execute the script with the |
| 1021 | proper set of perl C<-I> options. |
| 1022 | |
| 1023 | MakeMaker also checks for any files matching glob("t/*.t"). It will |
| 1024 | execute all matching files in alphabetical order via the |
| 1025 | L<Test::Harness> module with the C<-I> switches set correctly. |
| 1026 | |
| 1027 | If you'd like to see the raw output of your tests, set the |
| 1028 | C<TEST_VERBOSE> variable to true. |
| 1029 | |
| 1030 | make test TEST_VERBOSE=1 |
| 1031 | |
| 1032 | =head2 make testdb |
| 1033 | |
| 1034 | A useful variation of the above is the target C<testdb>. It runs the |
| 1035 | test under the Perl debugger (see L<perldebug>). If the file |
| 1036 | F<test.pl> exists in the current directory, it is used for the test. |
| 1037 | |
| 1038 | If you want to debug some other testfile, set the C<TEST_FILE> variable |
| 1039 | thusly: |
| 1040 | |
| 1041 | make testdb TEST_FILE=t/mytest.t |
| 1042 | |
| 1043 | By default the debugger is called using C<-d> option to perl. If you |
| 1044 | want to specify some other option, set the C<TESTDB_SW> variable: |
| 1045 | |
| 1046 | make testdb TESTDB_SW=-Dx |
| 1047 | |
| 1048 | =head2 make install |
| 1049 | |
| 1050 | make alone puts all relevant files into directories that are named by |
| 1051 | the macros INST_LIB, INST_ARCHLIB, INST_SCRIPT, INST_MAN1DIR and |
| 1052 | INST_MAN3DIR. All these default to something below ./blib if you are |
| 1053 | I<not> building below the perl source directory. If you I<are> |
| 1054 | building below the perl source, INST_LIB and INST_ARCHLIB default to |
| 1055 | ../../lib, and INST_SCRIPT is not defined. |
| 1056 | |
| 1057 | The I<install> target of the generated Makefile copies the files found |
| 1058 | below each of the INST_* directories to their INSTALL* |
| 1059 | counterparts. Which counterparts are chosen depends on the setting of |
| 1060 | INSTALLDIRS according to the following table: |
| 1061 | |
| 1062 | INSTALLDIRS set to |
| 1063 | perl site vendor |
| 1064 | |
| 1065 | PERLPREFIX SITEPREFIX VENDORPREFIX |
| 1066 | INST_ARCHLIB INSTALLARCHLIB INSTALLSITEARCH INSTALLVENDORARCH |
| 1067 | INST_LIB INSTALLPRIVLIB INSTALLSITELIB INSTALLVENDORLIB |
| 1068 | INST_BIN INSTALLBIN INSTALLSITEBIN INSTALLVENDORBIN |
| 1069 | INST_SCRIPT INSTALLSCRIPT INSTALLSCRIPT INSTALLSCRIPT |
| 1070 | INST_MAN1DIR INSTALLMAN1DIR INSTALLSITEMAN1DIR INSTALLVENDORMAN1DIR |
| 1071 | INST_MAN3DIR INSTALLMAN3DIR INSTALLSITEMAN3DIR INSTALLVENDORMAN3DIR |
| 1072 | |
| 1073 | The INSTALL... macros in turn default to their %Config |
| 1074 | ($Config{installprivlib}, $Config{installarchlib}, etc.) counterparts. |
| 1075 | |
| 1076 | You can check the values of these variables on your system with |
| 1077 | |
| 1078 | perl '-V:install.*' |
| 1079 | |
| 1080 | And to check the sequence in which the library directories are |
| 1081 | searched by perl, run |
| 1082 | |
| 1083 | perl -le 'print join $/, @INC' |
| 1084 | |
| 1085 | |
| 1086 | =head2 PREFIX and LIB attribute |
| 1087 | |
| 1088 | PREFIX and LIB can be used to set several INSTALL* attributes in one |
| 1089 | go. The quickest way to install a module in a non-standard place might |
| 1090 | be |
| 1091 | |
| 1092 | perl Makefile.PL PREFIX=~ |
| 1093 | |
| 1094 | This will install all files in the module under your home directory, |
| 1095 | with man pages and libraries going into an appropriate place (usually |
| 1096 | ~/man and ~/lib). |
| 1097 | |
| 1098 | Another way to specify many INSTALL directories with a single |
| 1099 | parameter is LIB. |
| 1100 | |
| 1101 | perl Makefile.PL LIB=~/lib |
| 1102 | |
| 1103 | This will install the module's architecture-independent files into |
| 1104 | ~/lib, the architecture-dependent files into ~/lib/$archname. |
| 1105 | |
| 1106 | Note, that in both cases the tilde expansion is done by MakeMaker, not |
| 1107 | by perl by default, nor by make. |
| 1108 | |
| 1109 | Conflicts between parameters LIB, PREFIX and the various INSTALL* |
| 1110 | arguments are resolved so that: |
| 1111 | |
| 1112 | =over 4 |
| 1113 | |
| 1114 | =item * |
| 1115 | |
| 1116 | setting LIB overrides any setting of INSTALLPRIVLIB, INSTALLARCHLIB, |
| 1117 | INSTALLSITELIB, INSTALLSITEARCH (and they are not affected by PREFIX); |
| 1118 | |
| 1119 | =item * |
| 1120 | |
| 1121 | without LIB, setting PREFIX replaces the initial C<$Config{prefix}> |
| 1122 | part of those INSTALL* arguments, even if the latter are explicitly |
| 1123 | set (but are set to still start with C<$Config{prefix}>). |
| 1124 | |
| 1125 | =back |
| 1126 | |
| 1127 | If the user has superuser privileges, and is not working on AFS or |
| 1128 | relatives, then the defaults for INSTALLPRIVLIB, INSTALLARCHLIB, |
| 1129 | INSTALLSCRIPT, etc. will be appropriate, and this incantation will be |
| 1130 | the best: |
| 1131 | |
| 1132 | perl Makefile.PL; |
| 1133 | make; |
| 1134 | make test |
| 1135 | make install |
| 1136 | |
| 1137 | make install per default writes some documentation of what has been |
| 1138 | done into the file C<$(INSTALLARCHLIB)/perllocal.pod>. This feature |
| 1139 | can be bypassed by calling make pure_install. |
| 1140 | |
| 1141 | =head2 AFS users |
| 1142 | |
| 1143 | will have to specify the installation directories as these most |
| 1144 | probably have changed since perl itself has been installed. They will |
| 1145 | have to do this by calling |
| 1146 | |
| 1147 | perl Makefile.PL INSTALLSITELIB=/afs/here/today \ |
| 1148 | INSTALLSCRIPT=/afs/there/now INSTALLMAN3DIR=/afs/for/manpages |
| 1149 | make |
| 1150 | |
| 1151 | Be careful to repeat this procedure every time you recompile an |
| 1152 | extension, unless you are sure the AFS installation directories are |
| 1153 | still valid. |
| 1154 | |
| 1155 | =head2 Static Linking of a new Perl Binary |
| 1156 | |
| 1157 | An extension that is built with the above steps is ready to use on |
| 1158 | systems supporting dynamic loading. On systems that do not support |
| 1159 | dynamic loading, any newly created extension has to be linked together |
| 1160 | with the available resources. MakeMaker supports the linking process |
| 1161 | by creating appropriate targets in the Makefile whenever an extension |
| 1162 | is built. You can invoke the corresponding section of the makefile with |
| 1163 | |
| 1164 | make perl |
| 1165 | |
| 1166 | That produces a new perl binary in the current directory with all |
| 1167 | extensions linked in that can be found in INST_ARCHLIB, SITELIBEXP, |
| 1168 | and PERL_ARCHLIB. To do that, MakeMaker writes a new Makefile, on |
| 1169 | UNIX, this is called Makefile.aperl (may be system dependent). If you |
| 1170 | want to force the creation of a new perl, it is recommended, that you |
| 1171 | delete this Makefile.aperl, so the directories are searched-through |
| 1172 | for linkable libraries again. |
| 1173 | |
| 1174 | The binary can be installed into the directory where perl normally |
| 1175 | resides on your machine with |
| 1176 | |
| 1177 | make inst_perl |
| 1178 | |
| 1179 | To produce a perl binary with a different name than C<perl>, either say |
| 1180 | |
| 1181 | perl Makefile.PL MAP_TARGET=myperl |
| 1182 | make myperl |
| 1183 | make inst_perl |
| 1184 | |
| 1185 | or say |
| 1186 | |
| 1187 | perl Makefile.PL |
| 1188 | make myperl MAP_TARGET=myperl |
| 1189 | make inst_perl MAP_TARGET=myperl |
| 1190 | |
| 1191 | In any case you will be prompted with the correct invocation of the |
| 1192 | C<inst_perl> target that installs the new binary into INSTALLBIN. |
| 1193 | |
| 1194 | make inst_perl per default writes some documentation of what has been |
| 1195 | done into the file C<$(INSTALLARCHLIB)/perllocal.pod>. This |
| 1196 | can be bypassed by calling make pure_inst_perl. |
| 1197 | |
| 1198 | Warning: the inst_perl: target will most probably overwrite your |
| 1199 | existing perl binary. Use with care! |
| 1200 | |
| 1201 | Sometimes you might want to build a statically linked perl although |
| 1202 | your system supports dynamic loading. In this case you may explicitly |
| 1203 | set the linktype with the invocation of the Makefile.PL or make: |
| 1204 | |
| 1205 | perl Makefile.PL LINKTYPE=static # recommended |
| 1206 | |
| 1207 | or |
| 1208 | |
| 1209 | make LINKTYPE=static # works on most systems |
| 1210 | |
| 1211 | =head2 Determination of Perl Library and Installation Locations |
| 1212 | |
| 1213 | MakeMaker needs to know, or to guess, where certain things are |
| 1214 | located. Especially INST_LIB and INST_ARCHLIB (where to put the files |
| 1215 | during the make(1) run), PERL_LIB and PERL_ARCHLIB (where to read |
| 1216 | existing modules from), and PERL_INC (header files and C<libperl*.*>). |
| 1217 | |
| 1218 | Extensions may be built either using the contents of the perl source |
| 1219 | directory tree or from the installed perl library. The recommended way |
| 1220 | is to build extensions after you have run 'make install' on perl |
| 1221 | itself. You can do that in any directory on your hard disk that is not |
| 1222 | below the perl source tree. The support for extensions below the ext |
| 1223 | directory of the perl distribution is only good for the standard |
| 1224 | extensions that come with perl. |
| 1225 | |
| 1226 | If an extension is being built below the C<ext/> directory of the perl |
| 1227 | source then MakeMaker will set PERL_SRC automatically (e.g., |
| 1228 | C<../..>). If PERL_SRC is defined and the extension is recognized as |
| 1229 | a standard extension, then other variables default to the following: |
| 1230 | |
| 1231 | PERL_INC = PERL_SRC |
| 1232 | PERL_LIB = PERL_SRC/lib |
| 1233 | PERL_ARCHLIB = PERL_SRC/lib |
| 1234 | INST_LIB = PERL_LIB |
| 1235 | INST_ARCHLIB = PERL_ARCHLIB |
| 1236 | |
| 1237 | If an extension is being built away from the perl source then MakeMaker |
| 1238 | will leave PERL_SRC undefined and default to using the installed copy |
| 1239 | of the perl library. The other variables default to the following: |
| 1240 | |
| 1241 | PERL_INC = $archlibexp/CORE |
| 1242 | PERL_LIB = $privlibexp |
| 1243 | PERL_ARCHLIB = $archlibexp |
| 1244 | INST_LIB = ./blib/lib |
| 1245 | INST_ARCHLIB = ./blib/arch |
| 1246 | |
| 1247 | If perl has not yet been installed then PERL_SRC can be defined on the |
| 1248 | command line as shown in the previous section. |
| 1249 | |
| 1250 | |
| 1251 | =head2 Which architecture dependent directory? |
| 1252 | |
| 1253 | If you don't want to keep the defaults for the INSTALL* macros, |
| 1254 | MakeMaker helps you to minimize the typing needed: the usual |
| 1255 | relationship between INSTALLPRIVLIB and INSTALLARCHLIB is determined |
| 1256 | by Configure at perl compilation time. MakeMaker supports the user who |
| 1257 | sets INSTALLPRIVLIB. If INSTALLPRIVLIB is set, but INSTALLARCHLIB not, |
| 1258 | then MakeMaker defaults the latter to be the same subdirectory of |
| 1259 | INSTALLPRIVLIB as Configure decided for the counterparts in %Config , |
| 1260 | otherwise it defaults to INSTALLPRIVLIB. The same relationship holds |
| 1261 | for INSTALLSITELIB and INSTALLSITEARCH. |
| 1262 | |
| 1263 | MakeMaker gives you much more freedom than needed to configure |
| 1264 | internal variables and get different results. It is worth to mention, |
| 1265 | that make(1) also lets you configure most of the variables that are |
| 1266 | used in the Makefile. But in the majority of situations this will not |
| 1267 | be necessary, and should only be done if the author of a package |
| 1268 | recommends it (or you know what you're doing). |
| 1269 | |
| 1270 | =head2 Using Attributes and Parameters |
| 1271 | |
| 1272 | The following attributes may be specified as arguments to WriteMakefile() |
| 1273 | or as NAME=VALUE pairs on the command line. |
| 1274 | |
| 1275 | =over 2 |
| 1276 | |
| 1277 | =item ABSTRACT |
| 1278 | |
| 1279 | One line description of the module. Will be included in PPD file. |
| 1280 | |
| 1281 | =item ABSTRACT_FROM |
| 1282 | |
| 1283 | Name of the file that contains the package description. MakeMaker looks |
| 1284 | for a line in the POD matching /^($package\s-\s)(.*)/. This is typically |
| 1285 | the first line in the "=head1 NAME" section. $2 becomes the abstract. |
| 1286 | |
| 1287 | =item AUTHOR |
| 1288 | |
| 1289 | String containing name (and email address) of package author(s). Is used |
| 1290 | in PPD (Perl Package Description) files for PPM (Perl Package Manager). |
| 1291 | |
| 1292 | =item BINARY_LOCATION |
| 1293 | |
| 1294 | Used when creating PPD files for binary packages. It can be set to a |
| 1295 | full or relative path or URL to the binary archive for a particular |
| 1296 | architecture. For example: |
| 1297 | |
| 1298 | perl Makefile.PL BINARY_LOCATION=x86/Agent.tar.gz |
| 1299 | |
| 1300 | builds a PPD package that references a binary of the C<Agent> package, |
| 1301 | located in the C<x86> directory relative to the PPD itself. |
| 1302 | |
| 1303 | =item C |
| 1304 | |
| 1305 | Ref to array of *.c file names. Initialised from a directory scan |
| 1306 | and the values portion of the XS attribute hash. This is not |
| 1307 | currently used by MakeMaker but may be handy in Makefile.PLs. |
| 1308 | |
| 1309 | =item CCFLAGS |
| 1310 | |
| 1311 | String that will be included in the compiler call command line between |
| 1312 | the arguments INC and OPTIMIZE. |
| 1313 | |
| 1314 | =item CONFIG |
| 1315 | |
| 1316 | Arrayref. E.g. [qw(archname manext)] defines ARCHNAME & MANEXT from |
| 1317 | config.sh. MakeMaker will add to CONFIG the following values anyway: |
| 1318 | ar |
| 1319 | cc |
| 1320 | cccdlflags |
| 1321 | ccdlflags |
| 1322 | dlext |
| 1323 | dlsrc |
| 1324 | ld |
| 1325 | lddlflags |
| 1326 | ldflags |
| 1327 | libc |
| 1328 | lib_ext |
| 1329 | obj_ext |
| 1330 | ranlib |
| 1331 | sitelibexp |
| 1332 | sitearchexp |
| 1333 | so |
| 1334 | |
| 1335 | =item CONFIGURE |
| 1336 | |
| 1337 | CODE reference. The subroutine should return a hash reference. The |
| 1338 | hash may contain further attributes, e.g. {LIBS =E<gt> ...}, that have to |
| 1339 | be determined by some evaluation method. |
| 1340 | |
| 1341 | =item DEFINE |
| 1342 | |
| 1343 | Something like C<"-DHAVE_UNISTD_H"> |
| 1344 | |
| 1345 | =item DESTDIR |
| 1346 | |
| 1347 | This is the root directory into which the code will be installed. It |
| 1348 | I<prepends itself to the normal prefix>. For example, if your code |
| 1349 | would normally go into /usr/local/lib/perl you could set DESTDIR=/tmp |
| 1350 | and installation would go into /tmp/usr/local/lib/perl. |
| 1351 | |
| 1352 | This is primarily of use for people who repackage Perl modules. |
| 1353 | |
| 1354 | From the GNU Makefile conventions. |
| 1355 | |
| 1356 | =item DIR |
| 1357 | |
| 1358 | Ref to array of subdirectories containing Makefile.PLs e.g. [ 'sdbm' |
| 1359 | ] in ext/SDBM_File |
| 1360 | |
| 1361 | =item DISTNAME |
| 1362 | |
| 1363 | A safe filename for the package. |
| 1364 | |
| 1365 | Defaults to NAME above but with :: replaced with -. |
| 1366 | |
| 1367 | For example, Foo::Bar becomes Foo-Bar. |
| 1368 | |
| 1369 | =item DISTVNAME |
| 1370 | |
| 1371 | Your name for distributing the package with the version number |
| 1372 | included. This is used by 'make dist' to name the resulting archive |
| 1373 | file. |
| 1374 | |
| 1375 | Defaults to DISTNAME-VERSION. |
| 1376 | |
| 1377 | For example, version 1.04 of Foo::Bar becomes Foo-Bar-1.04. |
| 1378 | |
| 1379 | On some OS's where . has special meaning VERSION_SYM may be used in |
| 1380 | place of VERSION. |
| 1381 | |
| 1382 | =item DL_FUNCS |
| 1383 | |
| 1384 | Hashref of symbol names for routines to be made available as universal |
| 1385 | symbols. Each key/value pair consists of the package name and an |
| 1386 | array of routine names in that package. Used only under AIX, OS/2, |
| 1387 | VMS and Win32 at present. The routine names supplied will be expanded |
| 1388 | in the same way as XSUB names are expanded by the XS() macro. |
| 1389 | Defaults to |
| 1390 | |
| 1391 | {"$(NAME)" => ["boot_$(NAME)" ] } |
| 1392 | |
| 1393 | e.g. |
| 1394 | |
| 1395 | {"RPC" => [qw( boot_rpcb rpcb_gettime getnetconfigent )], |
| 1396 | "NetconfigPtr" => [ 'DESTROY'] } |
| 1397 | |
| 1398 | Please see the L<ExtUtils::Mksymlists> documentation for more information |
| 1399 | about the DL_FUNCS, DL_VARS and FUNCLIST attributes. |
| 1400 | |
| 1401 | =item DL_VARS |
| 1402 | |
| 1403 | Array of symbol names for variables to be made available as universal symbols. |
| 1404 | Used only under AIX, OS/2, VMS and Win32 at present. Defaults to []. |
| 1405 | (e.g. [ qw(Foo_version Foo_numstreams Foo_tree ) ]) |
| 1406 | |
| 1407 | =item EXCLUDE_EXT |
| 1408 | |
| 1409 | Array of extension names to exclude when doing a static build. This |
| 1410 | is ignored if INCLUDE_EXT is present. Consult INCLUDE_EXT for more |
| 1411 | details. (e.g. [ qw( Socket POSIX ) ] ) |
| 1412 | |
| 1413 | This attribute may be most useful when specified as a string on the |
| 1414 | command line: perl Makefile.PL EXCLUDE_EXT='Socket Safe' |
| 1415 | |
| 1416 | =item EXE_FILES |
| 1417 | |
| 1418 | Ref to array of executable files. The files will be copied to the |
| 1419 | INST_SCRIPT directory. Make realclean will delete them from there |
| 1420 | again. |
| 1421 | |
| 1422 | If your executables start with something like #!perl or |
| 1423 | #!/usr/bin/perl MakeMaker will change this to the path of the perl |
| 1424 | 'Makefile.PL' was invoked with so the programs will be sure to run |
| 1425 | properly even if perl is not in /usr/bin/perl. |
| 1426 | |
| 1427 | =item FIRST_MAKEFILE |
| 1428 | |
| 1429 | The name of the Makefile to be produced. This is used for the second |
| 1430 | Makefile that will be produced for the MAP_TARGET. |
| 1431 | |
| 1432 | Defaults to 'Makefile' or 'Descrip.MMS' on VMS. |
| 1433 | |
| 1434 | (Note: we couldn't use MAKEFILE because dmake uses this for something |
| 1435 | else). |
| 1436 | |
| 1437 | =item FULLPERL |
| 1438 | |
| 1439 | Perl binary able to run this extension, load XS modules, etc... |
| 1440 | |
| 1441 | =item FULLPERLRUN |
| 1442 | |
| 1443 | Like PERLRUN, except it uses FULLPERL. |
| 1444 | |
| 1445 | =item FULLPERLRUNINST |
| 1446 | |
| 1447 | Like PERLRUNINST, except it uses FULLPERL. |
| 1448 | |
| 1449 | =item FUNCLIST |
| 1450 | |
| 1451 | This provides an alternate means to specify function names to be |
| 1452 | exported from the extension. Its value is a reference to an |
| 1453 | array of function names to be exported by the extension. These |
| 1454 | names are passed through unaltered to the linker options file. |
| 1455 | |
| 1456 | =item H |
| 1457 | |
| 1458 | Ref to array of *.h file names. Similar to C. |
| 1459 | |
| 1460 | =item IMPORTS |
| 1461 | |
| 1462 | This attribute is used to specify names to be imported into the |
| 1463 | extension. Takes a hash ref. |
| 1464 | |
| 1465 | It is only used on OS/2 and Win32. |
| 1466 | |
| 1467 | =item INC |
| 1468 | |
| 1469 | Include file dirs eg: C<"-I/usr/5include -I/path/to/inc"> |
| 1470 | |
| 1471 | =item INCLUDE_EXT |
| 1472 | |
| 1473 | Array of extension names to be included when doing a static build. |
| 1474 | MakeMaker will normally build with all of the installed extensions when |
| 1475 | doing a static build, and that is usually the desired behavior. If |
| 1476 | INCLUDE_EXT is present then MakeMaker will build only with those extensions |
| 1477 | which are explicitly mentioned. (e.g. [ qw( Socket POSIX ) ]) |
| 1478 | |
| 1479 | It is not necessary to mention DynaLoader or the current extension when |
| 1480 | filling in INCLUDE_EXT. If the INCLUDE_EXT is mentioned but is empty then |
| 1481 | only DynaLoader and the current extension will be included in the build. |
| 1482 | |
| 1483 | This attribute may be most useful when specified as a string on the |
| 1484 | command line: perl Makefile.PL INCLUDE_EXT='POSIX Socket Devel::Peek' |
| 1485 | |
| 1486 | =item INSTALLARCHLIB |
| 1487 | |
| 1488 | Used by 'make install', which copies files from INST_ARCHLIB to this |
| 1489 | directory if INSTALLDIRS is set to perl. |
| 1490 | |
| 1491 | =item INSTALLBIN |
| 1492 | |
| 1493 | Directory to install binary files (e.g. tkperl) into if |
| 1494 | INSTALLDIRS=perl. |
| 1495 | |
| 1496 | =item INSTALLDIRS |
| 1497 | |
| 1498 | Determines which of the sets of installation directories to choose: |
| 1499 | perl, site or vendor. Defaults to site. |
| 1500 | |
| 1501 | =item INSTALLMAN1DIR |
| 1502 | |
| 1503 | =item INSTALLMAN3DIR |
| 1504 | |
| 1505 | These directories get the man pages at 'make install' time if |
| 1506 | INSTALLDIRS=perl. Defaults to $Config{installman*dir}. |
| 1507 | |
| 1508 | If set to 'none', no man pages will be installed. |
| 1509 | |
| 1510 | =item INSTALLPRIVLIB |
| 1511 | |
| 1512 | Used by 'make install', which copies files from INST_LIB to this |
| 1513 | directory if INSTALLDIRS is set to perl. |
| 1514 | |
| 1515 | Defaults to $Config{installprivlib}. |
| 1516 | |
| 1517 | =item INSTALLSCRIPT |
| 1518 | |
| 1519 | Used by 'make install' which copies files from INST_SCRIPT to this |
| 1520 | directory. |
| 1521 | |
| 1522 | =item INSTALLSITEARCH |
| 1523 | |
| 1524 | Used by 'make install', which copies files from INST_ARCHLIB to this |
| 1525 | directory if INSTALLDIRS is set to site (default). |
| 1526 | |
| 1527 | =item INSTALLSITEBIN |
| 1528 | |
| 1529 | Used by 'make install', which copies files from INST_BIN to this |
| 1530 | directory if INSTALLDIRS is set to site (default). |
| 1531 | |
| 1532 | =item INSTALLSITELIB |
| 1533 | |
| 1534 | Used by 'make install', which copies files from INST_LIB to this |
| 1535 | directory if INSTALLDIRS is set to site (default). |
| 1536 | |
| 1537 | =item INSTALLSITEMAN1DIR |
| 1538 | |
| 1539 | =item INSTALLSITEMAN3DIR |
| 1540 | |
| 1541 | These directories get the man pages at 'make install' time if |
| 1542 | INSTALLDIRS=site (default). Defaults to |
| 1543 | $(SITEPREFIX)/man/man$(MAN*EXT). |
| 1544 | |
| 1545 | If set to 'none', no man pages will be installed. |
| 1546 | |
| 1547 | =item INSTALLVENDORARCH |
| 1548 | |
| 1549 | Used by 'make install', which copies files from INST_ARCHLIB to this |
| 1550 | directory if INSTALLDIRS is set to vendor. |
| 1551 | |
| 1552 | =item INSTALLVENDORBIN |
| 1553 | |
| 1554 | Used by 'make install', which copies files from INST_BIN to this |
| 1555 | directory if INSTALLDIRS is set to vendor. |
| 1556 | |
| 1557 | =item INSTALLVENDORLIB |
| 1558 | |
| 1559 | Used by 'make install', which copies files from INST_LIB to this |
| 1560 | directory if INSTALLDIRS is set to vendor. |
| 1561 | |
| 1562 | =item INSTALLVENDORMAN1DIR |
| 1563 | |
| 1564 | =item INSTALLVENDORMAN3DIR |
| 1565 | |
| 1566 | These directories get the man pages at 'make install' time if |
| 1567 | INSTALLDIRS=vendor. Defaults to $(VENDORPREFIX)/man/man$(MAN*EXT). |
| 1568 | |
| 1569 | If set to 'none', no man pages will be installed. |
| 1570 | |
| 1571 | =item INST_ARCHLIB |
| 1572 | |
| 1573 | Same as INST_LIB for architecture dependent files. |
| 1574 | |
| 1575 | =item INST_BIN |
| 1576 | |
| 1577 | Directory to put real binary files during 'make'. These will be copied |
| 1578 | to INSTALLBIN during 'make install' |
| 1579 | |
| 1580 | =item INST_LIB |
| 1581 | |
| 1582 | Directory where we put library files of this extension while building |
| 1583 | it. |
| 1584 | |
| 1585 | =item INST_MAN1DIR |
| 1586 | |
| 1587 | Directory to hold the man pages at 'make' time |
| 1588 | |
| 1589 | =item INST_MAN3DIR |
| 1590 | |
| 1591 | Directory to hold the man pages at 'make' time |
| 1592 | |
| 1593 | =item INST_SCRIPT |
| 1594 | |
| 1595 | Directory, where executable files should be installed during |
| 1596 | 'make'. Defaults to "./blib/script", just to have a dummy location during |
| 1597 | testing. make install will copy the files in INST_SCRIPT to |
| 1598 | INSTALLSCRIPT. |
| 1599 | |
| 1600 | =item LD |
| 1601 | |
| 1602 | Program to be used to link libraries for dynamic loading. |
| 1603 | |
| 1604 | Defaults to $Config{ld}. |
| 1605 | |
| 1606 | =item LDDLFLAGS |
| 1607 | |
| 1608 | Any special flags that might need to be passed to ld to create a |
| 1609 | shared library suitable for dynamic loading. It is up to the makefile |
| 1610 | to use it. (See L<Config/lddlflags>) |
| 1611 | |
| 1612 | Defaults to $Config{lddlflags}. |
| 1613 | |
| 1614 | =item LDFROM |
| 1615 | |
| 1616 | Defaults to "$(OBJECT)" and is used in the ld command to specify |
| 1617 | what files to link/load from (also see dynamic_lib below for how to |
| 1618 | specify ld flags) |
| 1619 | |
| 1620 | =item LIB |
| 1621 | |
| 1622 | LIB should only be set at C<perl Makefile.PL> time but is allowed as a |
| 1623 | MakeMaker argument. It has the effect of setting both INSTALLPRIVLIB |
| 1624 | and INSTALLSITELIB to that value regardless any explicit setting of |
| 1625 | those arguments (or of PREFIX). INSTALLARCHLIB and INSTALLSITEARCH |
| 1626 | are set to the corresponding architecture subdirectory. |
| 1627 | |
| 1628 | =item LIBPERL_A |
| 1629 | |
| 1630 | The filename of the perllibrary that will be used together with this |
| 1631 | extension. Defaults to libperl.a. |
| 1632 | |
| 1633 | =item LIBS |
| 1634 | |
| 1635 | An anonymous array of alternative library |
| 1636 | specifications to be searched for (in order) until |
| 1637 | at least one library is found. E.g. |
| 1638 | |
| 1639 | 'LIBS' => ["-lgdbm", "-ldbm -lfoo", "-L/path -ldbm.nfs"] |
| 1640 | |
| 1641 | Mind, that any element of the array |
| 1642 | contains a complete set of arguments for the ld |
| 1643 | command. So do not specify |
| 1644 | |
| 1645 | 'LIBS' => ["-ltcl", "-ltk", "-lX11"] |
| 1646 | |
| 1647 | See ODBM_File/Makefile.PL for an example, where an array is needed. If |
| 1648 | you specify a scalar as in |
| 1649 | |
| 1650 | 'LIBS' => "-ltcl -ltk -lX11" |
| 1651 | |
| 1652 | MakeMaker will turn it into an array with one element. |
| 1653 | |
| 1654 | =item LINKTYPE |
| 1655 | |
| 1656 | 'static' or 'dynamic' (default unless usedl=undef in |
| 1657 | config.sh). Should only be used to force static linking (also see |
| 1658 | linkext below). |
| 1659 | |
| 1660 | =item MAKEAPERL |
| 1661 | |
| 1662 | Boolean which tells MakeMaker, that it should include the rules to |
| 1663 | make a perl. This is handled automatically as a switch by |
| 1664 | MakeMaker. The user normally does not need it. |
| 1665 | |
| 1666 | =item MAKEFILE_OLD |
| 1667 | |
| 1668 | When 'make clean' or similar is run, the $(FIRST_MAKEFILE) will be |
| 1669 | backed up at this location. |
| 1670 | |
| 1671 | Defaults to $(FIRST_MAKEFILE).old or $(FIRST_MAKEFILE)_old on VMS. |
| 1672 | |
| 1673 | =item MAN1PODS |
| 1674 | |
| 1675 | Hashref of pod-containing files. MakeMaker will default this to all |
| 1676 | EXE_FILES files that include POD directives. The files listed |
| 1677 | here will be converted to man pages and installed as was requested |
| 1678 | at Configure time. |
| 1679 | |
| 1680 | =item MAN3PODS |
| 1681 | |
| 1682 | Hashref that assigns to *.pm and *.pod files the files into which the |
| 1683 | manpages are to be written. MakeMaker parses all *.pod and *.pm files |
| 1684 | for POD directives. Files that contain POD will be the default keys of |
| 1685 | the MAN3PODS hashref. These will then be converted to man pages during |
| 1686 | C<make> and will be installed during C<make install>. |
| 1687 | |
| 1688 | =item MAP_TARGET |
| 1689 | |
| 1690 | If it is intended, that a new perl binary be produced, this variable |
| 1691 | may hold a name for that binary. Defaults to perl |
| 1692 | |
| 1693 | =item MYEXTLIB |
| 1694 | |
| 1695 | If the extension links to a library that it builds set this to the |
| 1696 | name of the library (see SDBM_File) |
| 1697 | |
| 1698 | =item NAME |
| 1699 | |
| 1700 | Perl module name for this extension (DBD::Oracle). This will default |
| 1701 | to the directory name but should be explicitly defined in the |
| 1702 | Makefile.PL. |
| 1703 | |
| 1704 | =item NEEDS_LINKING |
| 1705 | |
| 1706 | MakeMaker will figure out if an extension contains linkable code |
| 1707 | anywhere down the directory tree, and will set this variable |
| 1708 | accordingly, but you can speed it up a very little bit if you define |
| 1709 | this boolean variable yourself. |
| 1710 | |
| 1711 | =item NOECHO |
| 1712 | |
| 1713 | Command so make does not print the literal commands its running. |
| 1714 | |
| 1715 | By setting it to an empty string you can generate a Makefile that |
| 1716 | prints all commands. Mainly used in debugging MakeMaker itself. |
| 1717 | |
| 1718 | Defaults to C<@>. |
| 1719 | |
| 1720 | =item NORECURS |
| 1721 | |
| 1722 | Boolean. Attribute to inhibit descending into subdirectories. |
| 1723 | |
| 1724 | =item NO_VC |
| 1725 | |
| 1726 | In general, any generated Makefile checks for the current version of |
| 1727 | MakeMaker and the version the Makefile was built under. If NO_VC is |
| 1728 | set, the version check is neglected. Do not write this into your |
| 1729 | Makefile.PL, use it interactively instead. |
| 1730 | |
| 1731 | =item OBJECT |
| 1732 | |
| 1733 | List of object files, defaults to '$(BASEEXT)$(OBJ_EXT)', but can be a long |
| 1734 | string containing all object files, e.g. "tkpBind.o |
| 1735 | tkpButton.o tkpCanvas.o" |
| 1736 | |
| 1737 | (Where BASEEXT is the last component of NAME, and OBJ_EXT is $Config{obj_ext}.) |
| 1738 | |
| 1739 | =item OPTIMIZE |
| 1740 | |
| 1741 | Defaults to C<-O>. Set it to C<-g> to turn debugging on. The flag is |
| 1742 | passed to subdirectory makes. |
| 1743 | |
| 1744 | =item PERL |
| 1745 | |
| 1746 | Perl binary for tasks that can be done by miniperl |
| 1747 | |
| 1748 | =item PERL_CORE |
| 1749 | |
| 1750 | Set only when MakeMaker is building the extensions of the Perl core |
| 1751 | distribution. |
| 1752 | |
| 1753 | =item PERLMAINCC |
| 1754 | |
| 1755 | The call to the program that is able to compile perlmain.c. Defaults |
| 1756 | to $(CC). |
| 1757 | |
| 1758 | =item PERL_ARCHLIB |
| 1759 | |
| 1760 | Same as for PERL_LIB, but for architecture dependent files. |
| 1761 | |
| 1762 | Used only when MakeMaker is building the extensions of the Perl core |
| 1763 | distribution (because normally $(PERL_ARCHLIB) is automatically in @INC, |
| 1764 | and adding it would get in the way of PERL5LIB). |
| 1765 | |
| 1766 | =item PERL_LIB |
| 1767 | |
| 1768 | Directory containing the Perl library to use. |
| 1769 | |
| 1770 | Used only when MakeMaker is building the extensions of the Perl core |
| 1771 | distribution (because normally $(PERL_LIB) is automatically in @INC, |
| 1772 | and adding it would get in the way of PERL5LIB). |
| 1773 | |
| 1774 | =item PERL_MALLOC_OK |
| 1775 | |
| 1776 | defaults to 0. Should be set to TRUE if the extension can work with |
| 1777 | the memory allocation routines substituted by the Perl malloc() subsystem. |
| 1778 | This should be applicable to most extensions with exceptions of those |
| 1779 | |
| 1780 | =over 4 |
| 1781 | |
| 1782 | =item * |
| 1783 | |
| 1784 | with bugs in memory allocations which are caught by Perl's malloc(); |
| 1785 | |
| 1786 | =item * |
| 1787 | |
| 1788 | which interact with the memory allocator in other ways than via |
| 1789 | malloc(), realloc(), free(), calloc(), sbrk() and brk(); |
| 1790 | |
| 1791 | =item * |
| 1792 | |
| 1793 | which rely on special alignment which is not provided by Perl's malloc(). |
| 1794 | |
| 1795 | =back |
| 1796 | |
| 1797 | B<NOTE.> Negligence to set this flag in I<any one> of loaded extension |
| 1798 | nullifies many advantages of Perl's malloc(), such as better usage of |
| 1799 | system resources, error detection, memory usage reporting, catchable failure |
| 1800 | of memory allocations, etc. |
| 1801 | |
| 1802 | =item PERLPREFIX |
| 1803 | |
| 1804 | Directory under which core modules are to be installed. |
| 1805 | |
| 1806 | Defaults to $Config{installprefixexp} falling back to |
| 1807 | $Config{installprefix}, $Config{prefixexp} or $Config{prefix} should |
| 1808 | $Config{installprefixexp} not exist. |
| 1809 | |
| 1810 | Overridden by PREFIX. |
| 1811 | |
| 1812 | =item PERLRUN |
| 1813 | |
| 1814 | Use this instead of $(PERL) when you wish to run perl. It will set up |
| 1815 | extra necessary flags for you. |
| 1816 | |
| 1817 | =item PERLRUNINST |
| 1818 | |
| 1819 | Use this instead of $(PERL) when you wish to run perl to work with |
| 1820 | modules. It will add things like -I$(INST_ARCH) and other necessary |
| 1821 | flags so perl can see the modules you're about to install. |
| 1822 | |
| 1823 | =item PERL_SRC |
| 1824 | |
| 1825 | Directory containing the Perl source code (use of this should be |
| 1826 | avoided, it may be undefined) |
| 1827 | |
| 1828 | =item PERM_RW |
| 1829 | |
| 1830 | Desired permission for read/writable files. Defaults to C<644>. |
| 1831 | See also L<MM_Unix/perm_rw>. |
| 1832 | |
| 1833 | =item PERM_RWX |
| 1834 | |
| 1835 | Desired permission for executable files. Defaults to C<755>. |
| 1836 | See also L<MM_Unix/perm_rwx>. |
| 1837 | |
| 1838 | =item PL_FILES |
| 1839 | |
| 1840 | Ref to hash of files to be processed as perl programs. MakeMaker |
| 1841 | will default to any found *.PL file (except Makefile.PL) being keys |
| 1842 | and the basename of the file being the value. E.g. |
| 1843 | |
| 1844 | {'foobar.PL' => 'foobar'} |
| 1845 | |
| 1846 | The *.PL files are expected to produce output to the target files |
| 1847 | themselves. If multiple files can be generated from the same *.PL |
| 1848 | file then the value in the hash can be a reference to an array of |
| 1849 | target file names. E.g. |
| 1850 | |
| 1851 | {'foobar.PL' => ['foobar1','foobar2']} |
| 1852 | |
| 1853 | =item PM |
| 1854 | |
| 1855 | Hashref of .pm files and *.pl files to be installed. e.g. |
| 1856 | |
| 1857 | {'name_of_file.pm' => '$(INST_LIBDIR)/install_as.pm'} |
| 1858 | |
| 1859 | By default this will include *.pm and *.pl and the files found in |
| 1860 | the PMLIBDIRS directories. Defining PM in the |
| 1861 | Makefile.PL will override PMLIBDIRS. |
| 1862 | |
| 1863 | =item PMLIBDIRS |
| 1864 | |
| 1865 | Ref to array of subdirectories containing library files. Defaults to |
| 1866 | [ 'lib', $(BASEEXT) ]. The directories will be scanned and I<any> files |
| 1867 | they contain will be installed in the corresponding location in the |
| 1868 | library. A libscan() method can be used to alter the behaviour. |
| 1869 | Defining PM in the Makefile.PL will override PMLIBDIRS. |
| 1870 | |
| 1871 | (Where BASEEXT is the last component of NAME.) |
| 1872 | |
| 1873 | =item PM_FILTER |
| 1874 | |
| 1875 | A filter program, in the traditional Unix sense (input from stdin, output |
| 1876 | to stdout) that is passed on each .pm file during the build (in the |
| 1877 | pm_to_blib() phase). It is empty by default, meaning no filtering is done. |
| 1878 | |
| 1879 | Great care is necessary when defining the command if quoting needs to be |
| 1880 | done. For instance, you would need to say: |
| 1881 | |
| 1882 | {'PM_FILTER' => 'grep -v \\"^\\#\\"'} |
| 1883 | |
| 1884 | to remove all the leading coments on the fly during the build. The |
| 1885 | extra \\ are necessary, unfortunately, because this variable is interpolated |
| 1886 | within the context of a Perl program built on the command line, and double |
| 1887 | quotes are what is used with the -e switch to build that command line. The |
| 1888 | # is escaped for the Makefile, since what is going to be generated will then |
| 1889 | be: |
| 1890 | |
| 1891 | PM_FILTER = grep -v \"^\#\" |
| 1892 | |
| 1893 | Without the \\ before the #, we'd have the start of a Makefile comment, |
| 1894 | and the macro would be incorrectly defined. |
| 1895 | |
| 1896 | =item POLLUTE |
| 1897 | |
| 1898 | Release 5.005 grandfathered old global symbol names by providing preprocessor |
| 1899 | macros for extension source compatibility. As of release 5.6, these |
| 1900 | preprocessor definitions are not available by default. The POLLUTE flag |
| 1901 | specifies that the old names should still be defined: |
| 1902 | |

| 1906 | a module under 5.6 or later. |
| 1907 | |
| 1908 | =item PPM_INSTALL_EXEC |
| 1909 | |
| 1910 | Name of the executable used to run C<PPM_INSTALL_SCRIPT> below. (e.g. perl) |
| 1911 | |
| 1912 | =item PPM_INSTALL_SCRIPT |
| 1913 | |
| 1914 | Name of the script that gets executed by the Perl Package Manager after |
| 1915 | the installation of a package. |
| 1916 | |
| 1917 | =item PREFIX |
| 1918 | |
| 1919 | This overrides all the default install locations. Man pages, |
| 1920 | libraries, scripts, etc... MakeMaker will try to make an educated |
| 1921 | guess about where to place things under the new PREFIX based on your |
| 1922 | Config defaults. Failing that, it will fall back to a structure |
| 1923 | which should be sensible for your platform. |
| 1924 | |
| 1925 | If you specify LIB or any INSTALL* variables they will not be effected |
| 1926 | by the PREFIX. |
| 1927 | |
| 1928 | =item PREREQ_FATAL |
| 1929 | |
| 1930 | Bool. If this parameter is true, failing to have the required modules |
| 1931 | (or the right versions thereof) will be fatal. perl Makefile.PL will die |
| 1932 | with the proper message. |
| 1933 | |
| 1934 | Note: see L<Test::Harness> for a shortcut for stopping tests early if |
| 1935 | you are missing dependencies. |
| 1936 | |
| 1937 | Do I<not> use this parameter for simple requirements, which could be resolved |
| 1938 | at a later time, e.g. after an unsuccessful B<make test> of your module. |
| 1939 | |
| 1940 | It is I<extremely> rare to have to use C<PREREQ_FATAL> at all! |
| 1941 | |
| 1942 | =item PREREQ_PM |
| 1943 | |
| 1944 | Hashref: Names of modules that need to be available to run this |
| 1945 | extension (e.g. Fcntl for SDBM_File) are the keys of the hash and the |
| 1946 | desired version is the value. If the required version number is 0, we |
| 1947 | only check if any version is installed already. |
| 1948 | |
| 1949 | =item PREREQ_PRINT |
| 1950 | |
| 1951 | Bool. If this parameter is true, the prerequisites will be printed to |
| 1952 | stdout and MakeMaker will exit. The output format is |
| 1953 | |
| 1954 | $PREREQ_PM = { |
| 1955 | 'A::B' => Vers1, |
| 1956 | 'C::D' => Vers2, |
| 1957 | ... |
| 1958 | }; |
| 1959 | |
| 1960 | =item PRINT_PREREQ |
| 1961 | |
| 1962 | RedHatism for C<PREREQ_PRINT>. The output format is different, though: |
| 1963 | |
| 1964 | perl(A::B)>=Vers1 perl(C::D)>=Vers2 ... |
| 1965 | |
| 1966 | =item SITEPREFIX |
| 1967 | |
| 1968 | Like PERLPREFIX, but only for the site install locations. |
| 1969 | |
| 1970 | Defaults to $Config{siteprefixexp}. Perls prior to 5.6.0 didn't have |
| 1971 | an explicit siteprefix in the Config. In those cases |
| 1972 | $Config{installprefix} will be used. |
| 1973 | |
| 1974 | Overridable by PREFIX |
| 1975 | |
| 1976 | =item SKIP |
| 1977 | |
| 1978 | Arrayref. E.g. [qw(name1 name2)] skip (do not write) sections of the |
| 1979 | Makefile. Caution! Do not use the SKIP attribute for the negligible |
| 1980 | speedup. It may seriously damage the resulting Makefile. Only use it |
| 1981 | if you really need it. |
| 1982 | |
| 1983 | =item TYPEMAPS |
| 1984 | |
| 1985 | Ref to array of typemap file names. Use this when the typemaps are |
| 1986 | in some directory other than the current directory or when they are |
| 1987 | not named B<typemap>. The last typemap in the list takes |
| 1988 | precedence. A typemap in the current directory has highest |
| 1989 | precedence, even if it isn't listed in TYPEMAPS. The default system |
| 1990 | typemap has lowest precedence. |
| 1991 | |
| 1992 | =item VENDORPREFIX |
| 1993 | |
| 1994 | Like PERLPREFIX, but only for the vendor install locations. |
| 1995 | |
| 1996 | Defaults to $Config{vendorprefixexp}. |

| 1998 | Overridable by PREFIX |
| 1999 | |

| 2001 | |
| 2002 | If true, make install will be verbose |

| 2004 | =item VERSION |
| 2005 | |
| 2006 | Your version number for distributing the package. This defaults to |
| 2007 | 0.1. |
| 2008 | |
| 2009 | =item VERSION_FROM |
| 2010 | |
| 2011 | Instead of specifying the VERSION in the Makefile.PL you can let |
| 2012 | MakeMaker parse a file to determine the version number. The parsing |
| 2013 | routine requires that the file named by VERSION_FROM contains one |
| 2014 | single line to compute the version number. The first line in the file |
| 2015 | that contains the regular expression |
| 2016 | |
| 2017 | /([\$*])(([\w\:\']*)\bVERSION)\b.*\=/ |
| 2018 | |
| 2019 | will be evaluated with eval() and the value of the named variable |
| 2020 | B<after> the eval() will be assigned to the VERSION attribute of the |
| 2021 | MakeMaker object. The following lines will be parsed o.k.: |
| 2022 | |
| 2023 | $VERSION = '1.00'; |
| 2024 | *VERSION = \'1.01'; |
| 2025 | $VERSION = sprintf "%d.%03d", q$Revision: 1.111 $ =~ /(\d+)/g; |
| 2026 | $FOO::VERSION = '1.10'; |
| 2027 | *FOO::VERSION = \'1.11'; |
| 2028 | our $VERSION = 1.2.3; # new for perl5.6.0 |
| 2029 | |
| 2030 | but these will fail: |
| 2031 | |
| 2032 | my $VERSION = '1.01'; |
| 2033 | local $VERSION = '1.02'; |
| 2034 | local $FOO::VERSION = '1.30'; |
| 2035 | |
| 2036 | (Putting C<my> or C<local> on the preceding line will work o.k.) |
| 2037 | |
| 2038 | The file named in VERSION_FROM is not added as a dependency to |
| 2039 | Makefile. This is not really correct, but it would be a major pain |
| 2040 | during development to have to rewrite the Makefile for any smallish |
| 2041 | change in that file. If you want to make sure that the Makefile |
| 2042 | contains the correct VERSION macro after any change of the file, you |
| 2043 | would have to do something like |
| 2044 | |
| 2045 | depend => { Makefile => '$(VERSION_FROM)' } |
| 2046 | |
| 2047 | See attribute C<depend> below. |
| 2048 | |
| 2049 | =item VERSION_SYM |
| 2050 | |
| 2051 | A sanitized VERSION with . replaced by _. For places where . has |
| 2052 | special meaning (some filesystems, RCS labels, etc...) |
| 2053 | |
| 2054 | =item XS |
| 2055 | |
| 2056 | Hashref of .xs files. MakeMaker will default this. e.g. |
| 2057 | |
| 2058 | {'name_of_file.xs' => 'name_of_file.c'} |
| 2059 | |
| 2060 | The .c files will automatically be included in the list of files |
| 2061 | deleted by a make clean. |
| 2062 | |
| 2063 | =item XSOPT |
| 2064 | |
| 2065 | String of options to pass to xsubpp. This might include C<-C++> or |
| 2066 | C<-extern>. Do not include typemaps here; the TYPEMAP parameter exists for |
| 2067 | that purpose. |
| 2068 | |
| 2069 | =item XSPROTOARG |
| 2070 | |
| 2071 | May be set to an empty string, which is identical to C<-prototypes>, or |
| 2072 | C<-noprototypes>. See the xsubpp documentation for details. MakeMaker |
| 2073 | defaults to the empty string. |
| 2074 | |
| 2075 | =item XS_VERSION |
| 2076 | |
| 2077 | Your version number for the .xs file of this package. This defaults |
| 2078 | to the value of the VERSION attribute. |

| 2104 | |
| 2105 | If you specify COMPRESS, then SUFFIX should also be altered, as it is |
| 2106 | needed to tell make the target file of the compression. Setting |
| 2107 | DIST_CP to ln can be useful, if you need to preserve the timestamps on |
| 2108 | your files. DIST_CP can take the values 'cp', which copies the file, |
| 2109 | 'ln', which links the file, and 'best' which copies symbolic links and |
| 2110 | links the rest. Default is 'best'. |

| 2146 | =head2 Overriding MakeMaker Methods |
| 2147 | |
| 2148 | If you cannot achieve the desired Makefile behaviour by specifying |
| 2149 | attributes you may define private subroutines in the Makefile.PL. |
| 2150 | Each subroutine returns the text it wishes to have written to |
| 2151 | the Makefile. To override a section of the Makefile you can |
| 2152 | either say: |
| 2153 | |
| 2154 | sub MY::c_o { "new literal text" } |
| 2155 | |
| 2156 | or you can edit the default by saying something like: |
| 2157 | |
| 2158 | package MY; # so that "SUPER" works right |
| 2159 | sub c_o { |
| 2160 | my $inherited = shift->SUPER::c_o(@_); |
| 2161 | $inherited =~ s/old text/new text/; |
| 2162 | $inherited; |
| 2163 | } |
| 2164 | |
| 2165 | If you are running experiments with embedding perl as a library into |
| 2166 | other applications, you might find MakeMaker is not sufficient. You'd |
| 2167 | better have a look at ExtUtils::Embed which is a collection of utilities |
| 2168 | for embedding. |
| 2169 | |
| 2170 | If you still need a different solution, try to develop another |
| 2171 | subroutine that fits your needs and submit the diffs to |
| 2172 | F<makemaker@perl.org> |
| 2173 | |
| 2174 | For a complete description of all MakeMaker methods see |
| 2175 | L<ExtUtils::MM_Unix>. |
| 2176 | |
| 2177 | Here is a simple example of how to add a new target to the generated |
| 2178 | Makefile: |
| 2179 | |
| 2180 | sub MY::postamble { |
| 2181 | return <<'MAKE_FRAG'; |
| 2182 | $(MYEXTLIB): sdbm/Makefile |
| 2183 | cd sdbm && $(MAKE) all |
| 2184 | |
| 2185 | MAKE_FRAG |
| 2186 | } |
| 2187 | |
| 2188 | =head2 The End Of Cargo Cult Programming |
| 2189 | |
| 2190 | WriteMakefile() now does some basic sanity checks on its parameters to |
| 2191 | protect against typos and malformatted values. This means some things |
| 2192 | which happened to work in the past will now throw warnings and |
| 2193 | possibly produce internal errors. |
| 2194 | |
| 2195 | Some of the most common mistakes: |
| 2196 | |
| 2197 | =over 2 |
| 2198 | |
| 2199 | =item C<<MAN3PODS => ' '>> |
| 2200 | |
| 2201 | This is commonly used to supress the creation of man pages. MAN3PODS |
| 2202 | takes a hash ref not a string, but the above worked by accident in old |
| 2203 | versions of MakeMaker. |
| 2204 | |
| 2205 | The correct code is C<<MAN3PODS => { }>>. |
| 2206 | |
| 2207 | =back |
| 2208 | |
| 2209 | |
| 2210 | =head2 Hintsfile support |
| 2211 | |
| 2212 | MakeMaker.pm uses the architecture specific information from |
| 2213 | Config.pm. In addition it evaluates architecture specific hints files |
| 2214 | in a C<hints/> directory. The hints files are expected to be named |
| 2215 | like their counterparts in C<PERL_SRC/hints>, but with an C<.pl> file |
| 2216 | name extension (eg. C<next_3_2.pl>). They are simply C<eval>ed by |
| 2217 | MakeMaker within the WriteMakefile() subroutine, and can be used to |
| 2218 | execute commands as well as to include special variables. The rules |
| 2219 | which hintsfile is chosen are the same as in Configure. |
| 2220 | |
| 2221 | The hintsfile is eval()ed immediately after the arguments given to |
| 2222 | WriteMakefile are stuffed into a hash reference $self but before this |
| 2223 | reference becomes blessed. So if you want to do the equivalent to |
| 2224 | override or create an attribute you would say something like |
| 2225 | |
| 2226 | $self->{LIBS} = ['-ldbm -lucb -lc']; |
| 2227 | |
| 2228 | =head2 Distribution Support |
| 2229 | |
| 2230 | For authors of extensions MakeMaker provides several Makefile |
| 2231 | targets. Most of the support comes from the ExtUtils::Manifest module, |
| 2232 | where additional documentation can be found. |
| 2233 | |
| 2234 | =over 4 |
| 2235 | |
| 2236 | =item make distcheck |
| 2237 | |

| 2240 | details) |
| 2241 | |
| 2242 | =item make skipcheck |
| 2243 | |
| 2244 | reports which files are skipped due to the entries in the |

| 2246 | details) |
| 2247 | |
| 2248 | =item make distclean |
| 2249 | |
| 2250 | does a realclean first and then the distcheck. Note that this is not |
| 2251 | needed to build a new distribution as long as you are sure that the |
| 2252 | MANIFEST file is ok. |
| 2253 | |
| 2254 | =item make manifest |
| 2255 | |
| 2256 | rewrites the MANIFEST file, adding all remaining files found (See |
| 2257 | ExtUtils::Manifest::mkmanifest() for details) |
| 2258 | |
| 2259 | =item make distdir |
| 2260 | |
| 2261 | Copies all the files that are in the MANIFEST file to a newly created |
| 2262 | directory with the name C<$(DISTNAME)-$(VERSION)>. If that directory |
| 2263 | exists, it will be removed first. |
| 2264 | |
| 2265 | =item make disttest |
| 2266 | |
| 2267 | Makes a distdir first, and runs a C<perl Makefile.PL>, a make, and |
| 2268 | a make test in that directory. |
| 2269 | |
| 2270 | =item make tardist |
| 2271 | |
| 2272 | First does a distdir. Then a command $(PREOP) which defaults to a null |
| 2273 | command, followed by $(TOUNIX), which defaults to a null command under |
| 2274 | UNIX, and will convert files in distribution directory to UNIX format |
| 2275 | otherwise. Next it runs C<tar> on that directory into a tarfile and |
| 2276 | deletes the directory. Finishes with a command $(POSTOP) which |
| 2277 | defaults to a null command. |
| 2278 | |
| 2279 | =item make dist |
| 2280 | |
| 2281 | Defaults to $(DIST_DEFAULT) which in turn defaults to tardist. |
| 2282 | |
| 2283 | =item make uutardist |
| 2284 | |
| 2285 | Runs a tardist first and uuencodes the tarfile. |
| 2286 | |
| 2287 | =item make shdist |
| 2288 | |
| 2289 | First does a distdir. Then a command $(PREOP) which defaults to a null |
| 2290 | command. Next it runs C<shar> on that directory into a sharfile and |
| 2291 | deletes the intermediate directory again. Finishes with a command |
| 2292 | $(POSTOP) which defaults to a null command. Note: For shdist to work |
| 2293 | properly a C<shar> program that can handle directories is mandatory. |
| 2294 | |
| 2295 | =item make zipdist |
| 2296 | |
| 2297 | First does a distdir. Then a command $(PREOP) which defaults to a null |
| 2298 | command. Runs C<$(ZIP) $(ZIPFLAGS)> on that directory into a |
| 2299 | zipfile. Then deletes that directory. Finishes with a command |
| 2300 | $(POSTOP) which defaults to a null command. |
| 2301 | |
| 2302 | =item make ci |
| 2303 | |
| 2304 | Does a $(CI) and a $(RCS_LABEL) on all files in the MANIFEST file. |
| 2305 | |
| 2306 | =back |
| 2307 | |
| 2308 | Customization of the dist targets can be done by specifying a hash |
| 2309 | reference to the dist attribute of the WriteMakefile call. The |
| 2310 | following parameters are recognized: |
| 2311 | |
| 2312 | CI ('ci -u') |
| 2313 | COMPRESS ('gzip --best') |
| 2314 | POSTOP ('@ :') |
| 2315 | PREOP ('@ :') |
| 2316 | TO_UNIX (depends on the system) |
| 2317 | RCS_LABEL ('rcs -q -Nv$(VERSION_SYM):') |
| 2318 | SHAR ('shar') |
| 2319 | SUFFIX ('.gz') |
| 2320 | TAR ('tar') |
| 2321 | TARFLAGS ('cvf') |
| 2322 | ZIP ('zip') |
| 2323 | ZIPFLAGS ('-r') |
| 2324 | |
| 2325 | An example: |

| 2327 | WriteMakefile( 'dist' => { COMPRESS=>"bzip2", SUFFIX=>".bz2" }) |

| 2329 | =head2 Disabling an extension |
| 2330 | |
| 2331 | If some events detected in F<Makefile.PL> imply that there is no way |
| 2332 | to create the Module, but this is a normal state of things, then you |
| 2333 | can create a F<Makefile> which does nothing, but succeeds on all the |
| 2334 | "usual" build targets. To do so, use |
| 2335 | |
| 2336 | ExtUtils::MakeMaker::WriteEmptyMakefile(); |
| 2337 | |
| 2338 | instead of WriteMakefile(). |
| 2339 | |
| 2340 | This may be useful if other modules expect this module to be I<built> |
| 2341 | OK, as opposed to I<work> OK (say, this system-dependent module builds |
| 2342 | in a subdirectory of some other distribution, or is listed as a |
| 2343 | dependency in a CPAN::Bundle, but the functionality is supported by |
| 2344 | different means on the current architecture). |

| 2352 | my $value = prompt($message); |
| 2353 | my $value = prompt($message, $default); |
| 2354 | |
| 2355 | The C<prompt()> function provides an easy way to request user input |
| 2356 | used to write a makefile. It displays the $message as a prompt for |
| 2357 | input. If a $default is provided it will be used as a default. The |
| 2358 | function returns the $value selected by the user. |
| 2359 | |
| 2360 | If C<prompt()> detects that it is not running interactively and there |
| 2361 | is nothing on STDIN or if the PERL_MM_USE_DEFAULT environment variable |
| 2362 | is set to true, the $default will be used without prompting. This |
| 2363 | prevents automated processes from blocking on user input. |
| 2364 | |
| 2365 | If no $default is provided an empty string will be used instead. |
