335 | The extension you are trying to build apparently is rather old and |
336 | most probably outdated. We detect that from the fact, that a |
337 | subroutine "writeMakefile" is called, and this subroutine is not |
338 | supported anymore since about October 1994. |
40000a8c |
339 | |
4633a7c4 |
340 | Please contact the author or look into CPAN (details about CPAN can be |
341 | found in the FAQ and at http:/www.perl.com) for a more recent version |
342 | of the extension. If you're really desperate, you can try to change |
343 | the subroutine name from writeMakefile to WriteMakefile and rerun |
344 | 'perl Makefile.PL', but you're most probably left alone, when you do |
345 | so. |

982 | =head1 NAME |
983 | |
479d2113 |
984 | ExtUtils::MakeMaker - Create a module Makefile |
005c1a0e |
985 | |
986 | =head1 SYNOPSIS |
987 | |
e0678a30 |
988 | use ExtUtils::MakeMaker; |
005c1a0e |
989 | |
e0678a30 |
990 | WriteMakefile( ATTRIBUTE => VALUE [, ...] ); |
8e07c86e |
991 | |
005c1a0e |
992 | =head1 DESCRIPTION |
993 | |
994 | This utility is designed to write a Makefile for an extension module |
995 | from a Makefile.PL. It is based on the Makefile.SH model provided by |
996 | Andy Dougherty and the perl5-porters. |
997 | |
998 | It splits the task of generating the Makefile into several subroutines |
999 | that can be individually overridden. Each subroutine returns the text |
1000 | it wishes to have written to the Makefile. |
1001 | |
f1387719 |
1002 | MakeMaker is object oriented. Each directory below the current |
e0678a30 |
1003 | directory that contains a Makefile.PL is treated as a separate |
f1387719 |
1004 | object. This makes it possible to write an unlimited number of |
1005 | Makefiles with a single invocation of WriteMakefile(). |

bab2b58e |
1011 | The long answer is the rest of the manpage :-) |
005c1a0e |
1012 | |
1013 | =head2 Default Makefile Behaviour |
1014 | |
f1387719 |
1015 | The generated Makefile enables the user of the extension to invoke |
005c1a0e |
1016 | |
1017 | perl Makefile.PL # optionally "perl Makefile.PL verbose" |
1018 | make |
8e07c86e |
1019 | make test # optionally set TEST_VERBOSE=1 |
1020 | make install # See below |
005c1a0e |
1021 | |
1022 | The Makefile to be produced may be altered by adding arguments of the |
e05e23b1 |
1023 | form C<KEY=VALUE>. E.g. |
005c1a0e |
1024 | |
5dca256e |
1025 | perl Makefile.PL PREFIX=~ |
005c1a0e |
1026 | |
1027 | Other interesting targets in the generated Makefile are |
1028 | |
1029 | make config # to check if the Makefile is up-to-date |
8e07c86e |
1030 | make clean # delete local temp files (Makefile gets renamed) |
1031 | make realclean # delete derived files (including ./blib) |
e05e23b1 |
1032 | make ci # check in all the files in the MANIFEST file |
005c1a0e |
1033 | make dist # see below the Distribution Support section |
1034 | |
e05e23b1 |
1035 | =head2 make test |
1036 | |
bab2b58e |
1037 | MakeMaker checks for the existence of a file named F<test.pl> in the |
d5d4ec93 |
1038 | current directory and if it exists it execute the script with the |
1039 | proper set of perl C<-I> options. |
e05e23b1 |
1040 | |
1041 | MakeMaker also checks for any files matching glob("t/*.t"). It will |
d5d4ec93 |
1042 | execute all matching files in alphabetical order via the |
1043 | L<Test::Harness> module with the C<-I> switches set correctly. |
1044 | |
1045 | If you'd like to see the raw output of your tests, set the |
1046 | C<TEST_VERBOSE> variable to true. |
1047 | |
1048 | make test TEST_VERBOSE=1 |
e05e23b1 |
1049 | |
bab2b58e |
1050 | =head2 make testdb |
1051 | |
1052 | A useful variation of the above is the target C<testdb>. It runs the |
1053 | test under the Perl debugger (see L<perldebug>). If the file |
1054 | F<test.pl> exists in the current directory, it is used for the test. |
1055 | |
d5d4ec93 |
1056 | If you want to debug some other testfile, set the C<TEST_FILE> variable |
bab2b58e |
1057 | thusly: |
1058 | |
1059 | make testdb TEST_FILE=t/mytest.t |
1060 | |
1061 | By default the debugger is called using C<-d> option to perl. If you |
d5d4ec93 |
1062 | want to specify some other option, set the C<TESTDB_SW> variable: |
bab2b58e |
1063 | |
1064 | make testdb TESTDB_SW=-Dx |
1065 | |
e05e23b1 |
1066 | =head2 make install |
005c1a0e |
1067 | |
8e07c86e |
1068 | make alone puts all relevant files into directories that are named by |
f6d6199c |
1069 | the macros INST_LIB, INST_ARCHLIB, INST_SCRIPT, INST_MAN1DIR and |
1070 | INST_MAN3DIR. All these default to something below ./blib if you are |
1071 | I<not> building below the perl source directory. If you I<are> |
1072 | building below the perl source, INST_LIB and INST_ARCHLIB default to |
1073 | ../../lib, and INST_SCRIPT is not defined. |
005c1a0e |
1074 | |
e05e23b1 |
1075 | The I<install> target of the generated Makefile copies the files found |
1076 | below each of the INST_* directories to their INSTALL* |
1077 | counterparts. Which counterparts are chosen depends on the setting of |
1078 | INSTALLDIRS according to the following table: |
005c1a0e |
1079 | |
f6d6199c |
1080 | INSTALLDIRS set to |
5c161494 |
1081 | perl site vendor |
e05e23b1 |
1082 | |
479d2113 |
1083 | PERLPREFIX SITEPREFIX VENDORPREFIX |
5c161494 |
1084 | INST_ARCHLIB INSTALLARCHLIB INSTALLSITEARCH INSTALLVENDORARCH |
1085 | INST_LIB INSTALLPRIVLIB INSTALLSITELIB INSTALLVENDORLIB |
1086 | INST_BIN INSTALLBIN INSTALLSITEBIN INSTALLVENDORBIN |
1087 | INST_SCRIPT INSTALLSCRIPT INSTALLSCRIPT INSTALLSCRIPT |
1088 | INST_MAN1DIR INSTALLMAN1DIR INSTALLSITEMAN1DIR INSTALLVENDORMAN1DIR |
1089 | INST_MAN3DIR INSTALLMAN3DIR INSTALLSITEMAN3DIR INSTALLVENDORMAN3DIR |
005c1a0e |
1090 | |
8e07c86e |
1091 | The INSTALL... macros in turn default to their %Config |
1092 | ($Config{installprivlib}, $Config{installarchlib}, etc.) counterparts. |
005c1a0e |
1093 | |
3b03c0f3 |
1094 | You can check the values of these variables on your system with |
1095 | |
bab2b58e |
1096 | perl '-V:install.*' |
3b03c0f3 |
1097 | |
f1387719 |
1098 | And to check the sequence in which the library directories are |
1099 | searched by perl, run |
005c1a0e |
1100 | |
f1387719 |
1101 | perl -le 'print join $/, @INC' |
005c1a0e |
1102 | |
a7d1454b |
1103 | Sometimes older versions of the module you're installing live in other |
1104 | directories in @INC. Because Perl loads the first version of a module it |
1105 | finds, not the newest, you might accidentally get one of these older |
1106 | versions even after installing a brand new version. To delete I<all other |
1107 | versions of the module you're installing> (not simply older ones) set the |
1108 | C<UNINST> variable. |
1109 | |
1110 | make install UNINST=1 |
1111 | |
005c1a0e |
1112 | |
bab2b58e |
1113 | =head2 PREFIX and LIB attribute |
1114 | |
1115 | PREFIX and LIB can be used to set several INSTALL* attributes in one |
1116 | go. The quickest way to install a module in a non-standard place might |
1117 | be |
1118 | |
f6d6199c |
1119 | perl Makefile.PL PREFIX=~ |
005c1a0e |
1120 | |
f6d6199c |
1121 | This will install all files in the module under your home directory, |
1122 | with man pages and libraries going into an appropriate place (usually |
1123 | ~/man and ~/lib). |
bab2b58e |
1124 | |
1125 | Another way to specify many INSTALL directories with a single |
f6d6199c |
1126 | parameter is LIB. |
005c1a0e |
1127 | |
f6d6199c |
1128 | perl Makefile.PL LIB=~/lib |
005c1a0e |
1129 | |
f6d6199c |
1130 | This will install the module's architecture-independent files into |
1131 | ~/lib, the architecture-dependent files into ~/lib/$archname. |
005c1a0e |
1132 | |
bab2b58e |
1133 | Note, that in both cases the tilde expansion is done by MakeMaker, not |
e35b8f9e |
1134 | by perl by default, nor by make. |
1135 | |
f6d6199c |
1136 | Conflicts between parameters LIB, PREFIX and the various INSTALL* |
1137 | arguments are resolved so that: |
e35b8f9e |
1138 | |
1139 | =over 4 |
1140 | |
1141 | =item * |
1142 | |
1143 | setting LIB overrides any setting of INSTALLPRIVLIB, INSTALLARCHLIB, |
1144 | INSTALLSITELIB, INSTALLSITEARCH (and they are not affected by PREFIX); |
1145 | |
1146 | =item * |
1147 | |
1148 | without LIB, setting PREFIX replaces the initial C<$Config{prefix}> |
1149 | part of those INSTALL* arguments, even if the latter are explicitly |
1150 | set (but are set to still start with C<$Config{prefix}>). |
1151 | |
1152 | =back |
005c1a0e |
1153 | |
f6d6199c |
1154 | If the user has superuser privileges, and is not working on AFS or |
1155 | relatives, then the defaults for INSTALLPRIVLIB, INSTALLARCHLIB, |
1156 | INSTALLSCRIPT, etc. will be appropriate, and this incantation will be |
1157 | the best: |
005c1a0e |
1158 | |
e0678a30 |
1159 | perl Makefile.PL; |
1160 | make; |
1161 | make test |
005c1a0e |
1162 | make install |
1163 | |
8e07c86e |
1164 | make install per default writes some documentation of what has been |
e05e23b1 |
1165 | done into the file C<$(INSTALLARCHLIB)/perllocal.pod>. This feature |
1166 | can be bypassed by calling make pure_install. |
8e07c86e |
1167 | |
1168 | =head2 AFS users |
1169 | |
1170 | will have to specify the installation directories as these most |
1171 | probably have changed since perl itself has been installed. They will |
1172 | have to do this by calling |
1173 | |
e05e23b1 |
1174 | perl Makefile.PL INSTALLSITELIB=/afs/here/today \ |
f6d6199c |
1175 | INSTALLSCRIPT=/afs/there/now INSTALLMAN3DIR=/afs/for/manpages |
8e07c86e |
1176 | make |
1177 | |
e05e23b1 |
1178 | Be careful to repeat this procedure every time you recompile an |
1179 | extension, unless you are sure the AFS installation directories are |
1180 | still valid. |
005c1a0e |
1181 | |
8e07c86e |
1182 | =head2 Static Linking of a new Perl Binary |
005c1a0e |
1183 | |
1184 | An extension that is built with the above steps is ready to use on |
1185 | systems supporting dynamic loading. On systems that do not support |
1186 | dynamic loading, any newly created extension has to be linked together |
1187 | with the available resources. MakeMaker supports the linking process |
1188 | by creating appropriate targets in the Makefile whenever an extension |
1189 | is built. You can invoke the corresponding section of the makefile with |
1190 | |
1191 | make perl |
1192 | |
1193 | That produces a new perl binary in the current directory with all |
da7f727a |
1194 | extensions linked in that can be found in INST_ARCHLIB, SITELIBEXP, |
e05e23b1 |
1195 | and PERL_ARCHLIB. To do that, MakeMaker writes a new Makefile, on |
1196 | UNIX, this is called Makefile.aperl (may be system dependent). If you |
1197 | want to force the creation of a new perl, it is recommended, that you |
1198 | delete this Makefile.aperl, so the directories are searched-through |
1199 | for linkable libraries again. |
005c1a0e |
1200 | |
1201 | The binary can be installed into the directory where perl normally |
1202 | resides on your machine with |
1203 | |
1204 | make inst_perl |
1205 | |
1206 | To produce a perl binary with a different name than C<perl>, either say |
1207 | |
1208 | perl Makefile.PL MAP_TARGET=myperl |
1209 | make myperl |
1210 | make inst_perl |
1211 | |
1212 | or say |
1213 | |
1214 | perl Makefile.PL |
1215 | make myperl MAP_TARGET=myperl |
1216 | make inst_perl MAP_TARGET=myperl |
1217 | |
1218 | In any case you will be prompted with the correct invocation of the |
1219 | C<inst_perl> target that installs the new binary into INSTALLBIN. |
1220 | |
8e07c86e |
1221 | make inst_perl per default writes some documentation of what has been |
1222 | done into the file C<$(INSTALLARCHLIB)/perllocal.pod>. This |
1223 | can be bypassed by calling make pure_inst_perl. |
005c1a0e |
1224 | |
e05e23b1 |
1225 | Warning: the inst_perl: target will most probably overwrite your |
1226 | existing perl binary. Use with care! |
005c1a0e |
1227 | |
8e07c86e |
1228 | Sometimes you might want to build a statically linked perl although |
1229 | your system supports dynamic loading. In this case you may explicitly |
1230 | set the linktype with the invocation of the Makefile.PL or make: |
1231 | |
1232 | perl Makefile.PL LINKTYPE=static # recommended |
1233 | |
1234 | or |
1235 | |
1236 | make LINKTYPE=static # works on most systems |
1237 | |
005c1a0e |
1238 | =head2 Determination of Perl Library and Installation Locations |
1239 | |
1240 | MakeMaker needs to know, or to guess, where certain things are |
e05e23b1 |
1241 | located. Especially INST_LIB and INST_ARCHLIB (where to put the files |
1242 | during the make(1) run), PERL_LIB and PERL_ARCHLIB (where to read |
1243 | existing modules from), and PERL_INC (header files and C<libperl*.*>). |
005c1a0e |
1244 | |
1245 | Extensions may be built either using the contents of the perl source |
e05e23b1 |
1246 | directory tree or from the installed perl library. The recommended way |
1247 | is to build extensions after you have run 'make install' on perl |
1248 | itself. You can do that in any directory on your hard disk that is not |
1249 | below the perl source tree. The support for extensions below the ext |
1250 | directory of the perl distribution is only good for the standard |
1251 | extensions that come with perl. |
005c1a0e |
1252 | |
1253 | If an extension is being built below the C<ext/> directory of the perl |
e05e23b1 |
1254 | source then MakeMaker will set PERL_SRC automatically (e.g., |
1255 | C<../..>). If PERL_SRC is defined and the extension is recognized as |
1256 | a standard extension, then other variables default to the following: |
005c1a0e |
1257 | |
1258 | PERL_INC = PERL_SRC |
1259 | PERL_LIB = PERL_SRC/lib |
1260 | PERL_ARCHLIB = PERL_SRC/lib |
1261 | INST_LIB = PERL_LIB |
1262 | INST_ARCHLIB = PERL_ARCHLIB |
1263 | |
1264 | If an extension is being built away from the perl source then MakeMaker |
1265 | will leave PERL_SRC undefined and default to using the installed copy |
1266 | of the perl library. The other variables default to the following: |
1267 | |
e05e23b1 |
1268 | PERL_INC = $archlibexp/CORE |
1269 | PERL_LIB = $privlibexp |
1270 | PERL_ARCHLIB = $archlibexp |
1271 | INST_LIB = ./blib/lib |
1272 | INST_ARCHLIB = ./blib/arch |
005c1a0e |
1273 | |
1274 | If perl has not yet been installed then PERL_SRC can be defined on the |
1275 | command line as shown in the previous section. |
1276 | |
005c1a0e |
1277 | |
f1387719 |
1278 | =head2 Which architecture dependent directory? |
005c1a0e |
1279 | |
f1387719 |
1280 | If you don't want to keep the defaults for the INSTALL* macros, |
1281 | MakeMaker helps you to minimize the typing needed: the usual |
1282 | relationship between INSTALLPRIVLIB and INSTALLARCHLIB is determined |
1283 | by Configure at perl compilation time. MakeMaker supports the user who |
1284 | sets INSTALLPRIVLIB. If INSTALLPRIVLIB is set, but INSTALLARCHLIB not, |
1285 | then MakeMaker defaults the latter to be the same subdirectory of |
1286 | INSTALLPRIVLIB as Configure decided for the counterparts in %Config , |
1287 | otherwise it defaults to INSTALLPRIVLIB. The same relationship holds |
1288 | for INSTALLSITELIB and INSTALLSITEARCH. |
005c1a0e |
1289 | |
f1387719 |
1290 | MakeMaker gives you much more freedom than needed to configure |
1291 | internal variables and get different results. It is worth to mention, |
1292 | that make(1) also lets you configure most of the variables that are |
1293 | used in the Makefile. But in the majority of situations this will not |
a7665c5e |
1294 | be necessary, and should only be done if the author of a package |
f1387719 |
1295 | recommends it (or you know what you're doing). |

1297 | =head2 Using Attributes and Parameters |
005c1a0e |
1298 | |
a884ca7c |
1299 | The following attributes may be specified as arguments to WriteMakefile() |
1300 | or as NAME=VALUE pairs on the command line. |
005c1a0e |
1301 | |
875fa795 |
1302 | =over 2 |
005c1a0e |
1303 | |
875fa795 |
1304 | =item ABSTRACT |
1305 | |
1306 | One line description of the module. Will be included in PPD file. |
1307 | |
1308 | =item ABSTRACT_FROM |
1309 | |
1310 | Name of the file that contains the package description. MakeMaker looks |
1311 | for a line in the POD matching /^($package\s-\s)(.*)/. This is typically |
1312 | the first line in the "=head1 NAME" section. $2 becomes the abstract. |
1313 | |
e35b8f9e |
1314 | =item AUTHOR |
1315 | |
1316 | String containing name (and email address) of package author(s). Is used |
1317 | in PPD (Perl Package Description) files for PPM (Perl Package Manager). |
1318 | |
875fa795 |
1319 | =item BINARY_LOCATION |
1320 | |
1321 | Used when creating PPD files for binary packages. It can be set to a |
1322 | full or relative path or URL to the binary archive for a particular |
1323 | architecture. For example: |
1324 | |
f6d6199c |
1325 | perl Makefile.PL BINARY_LOCATION=x86/Agent.tar.gz |
875fa795 |
1326 | |
1327 | builds a PPD package that references a binary of the C<Agent> package, |
20e08411 |
1328 | located in the C<x86> directory relative to the PPD itself. |
8e07c86e |
1329 | |
864a5fa8 |
1330 | =item C |
8e07c86e |
1331 | |
864a5fa8 |
1332 | Ref to array of *.c file names. Initialised from a directory scan |
1333 | and the values portion of the XS attribute hash. This is not |
1334 | currently used by MakeMaker but may be handy in Makefile.PLs. |
8e07c86e |
1335 | |
84902520 |
1336 | =item CCFLAGS |
1337 | |
1338 | String that will be included in the compiler call command line between |
1339 | the arguments INC and OPTIMIZE. |
1340 | |
864a5fa8 |
1341 | =item CONFIG |
8e07c86e |
1342 | |
864a5fa8 |
1343 | Arrayref. E.g. [qw(archname manext)] defines ARCHNAME & MANEXT from |
1344 | config.sh. MakeMaker will add to CONFIG the following values anyway: |
1345 | ar |
1346 | cc |
1347 | cccdlflags |
1348 | ccdlflags |
1349 | dlext |
1350 | dlsrc |
1351 | ld |
1352 | lddlflags |
1353 | ldflags |
1354 | libc |
1355 | lib_ext |
1356 | obj_ext |
1357 | ranlib |
e05e23b1 |

864a5fa8 |
1360 | so |
8e07c86e |
1361 | |
1362 | =item CONFIGURE |
1363 | |
e05e23b1 |
1364 | CODE reference. The subroutine should return a hash reference. The |
1fef88e7 |
1365 | hash may contain further attributes, e.g. {LIBS =E<gt> ...}, that have to |
8e07c86e |
1366 | be determined by some evaluation method. |
1367 | |
864a5fa8 |
1368 | =item DEFINE |
8e07c86e |
1369 | |
864a5fa8 |
1370 | Something like C<"-DHAVE_UNISTD_H"> |
8e07c86e |
1371 | |
479d2113 |
1372 | =item DESTDIR |
1373 | |
1374 | This is the root directory into which the code will be installed. It |
1375 | I<prepends itself to the normal prefix>. For example, if your code |
5dca256e |
1376 | would normally go into F</usr/local/lib/perl> you could set DESTDIR=~/tmp/ |
1377 | and installation would go into F<~/tmp/usr/local/lib/perl>. |
479d2113 |
1378 | |
1379 | This is primarily of use for people who repackage Perl modules. |
1380 | |
531e2ba1 |
1381 | NOTE: Due to the nature of make, it is important that you put the trailing |
5dca256e |
1382 | slash on your DESTDIR. F<~/tmp/> not F<~/tmp>. |
479d2113 |
1383 | |
864a5fa8 |
1384 | =item DIR |
8e07c86e |
1385 | |
864a5fa8 |
1386 | Ref to array of subdirectories containing Makefile.PLs e.g. [ 'sdbm' |
1387 | ] in ext/SDBM_File |
8e07c86e |
1388 | |
864a5fa8 |
1389 | =item DISTNAME |
8e07c86e |
1390 | |
479d2113 |
1391 | A safe filename for the package. |
1392 | |
1393 | Defaults to NAME above but with :: replaced with -. |
1394 | |
1395 | For example, Foo::Bar becomes Foo-Bar. |
1396 | |
1397 | =item DISTVNAME |
1398 | |
1399 | Your name for distributing the package with the version number |
1400 | included. This is used by 'make dist' to name the resulting archive |
1401 | file. |
1402 | |
1403 | Defaults to DISTNAME-VERSION. |
1404 | |
1405 | For example, version 1.04 of Foo::Bar becomes Foo-Bar-1.04. |
1406 | |
1407 | On some OS's where . has special meaning VERSION_SYM may be used in |
1408 | place of VERSION. |
8e07c86e |
1409 | |
864a5fa8 |
1410 | =item DL_FUNCS |
8e07c86e |
1411 | |
875fa795 |
1412 | Hashref of symbol names for routines to be made available as universal |
1413 | symbols. Each key/value pair consists of the package name and an |
1414 | array of routine names in that package. Used only under AIX, OS/2, |
1415 | VMS and Win32 at present. The routine names supplied will be expanded |
1416 | in the same way as XSUB names are expanded by the XS() macro. |
1417 | Defaults to |
8e07c86e |
1418 | |
864a5fa8 |
1419 | {"$(NAME)" => ["boot_$(NAME)" ] } |
8e07c86e |
1420 | |
864a5fa8 |
1421 | e.g. |
8e07c86e |
1422 | |
864a5fa8 |
1423 | {"RPC" => [qw( boot_rpcb rpcb_gettime getnetconfigent )], |
1424 | "NetconfigPtr" => [ 'DESTROY'] } |
8e07c86e |
1425 | |
875fa795 |
1426 | Please see the L<ExtUtils::Mksymlists> documentation for more information |
1427 | about the DL_FUNCS, DL_VARS and FUNCLIST attributes. |
1428 | |
864a5fa8 |
1429 | =item DL_VARS |
8e07c86e |
1430 | |
875fa795 |
1431 | Array of symbol names for variables to be made available as universal symbols. |
1432 | Used only under AIX, OS/2, VMS and Win32 at present. Defaults to []. |
1433 | (e.g. [ qw(Foo_version Foo_numstreams Foo_tree ) ]) |
8e07c86e |
1434 | |
f1387719 |
1435 | =item EXCLUDE_EXT |
1436 | |
1437 | Array of extension names to exclude when doing a static build. This |
1438 | is ignored if INCLUDE_EXT is present. Consult INCLUDE_EXT for more |
1439 | details. (e.g. [ qw( Socket POSIX ) ] ) |
1440 | |
1441 | This attribute may be most useful when specified as a string on the |
de592821 |
1442 | command line: perl Makefile.PL EXCLUDE_EXT='Socket Safe' |
f1387719 |
1443 | |
864a5fa8 |
1444 | =item EXE_FILES |
8e07c86e |
1445 | |
864a5fa8 |
1446 | Ref to array of executable files. The files will be copied to the |
f1387719 |
1447 | INST_SCRIPT directory. Make realclean will delete them from there |
864a5fa8 |
1448 | again. |
8e07c86e |
1449 | |
2530b651 |
1450 | If your executables start with something like #!perl or |
1451 | #!/usr/bin/perl MakeMaker will change this to the path of the perl |
1452 | 'Makefile.PL' was invoked with so the programs will be sure to run |
1453 | properly even if perl is not in /usr/bin/perl. |
1454 | |
864a5fa8 |
1455 | =item FIRST_MAKEFILE |
1456 | |
479d2113 |
1457 | The name of the Makefile to be produced. This is used for the second |
1458 | Makefile that will be produced for the MAP_TARGET. |
1459 | |
1460 | Defaults to 'Makefile' or 'Descrip.MMS' on VMS. |
1461 | |
1462 | (Note: we couldn't use MAKEFILE because dmake uses this for something |
1463 | else). |
864a5fa8 |
1464 | |
1465 | =item FULLPERL |
8e07c86e |
1466 | |
75e2e551 |
1467 | Perl binary able to run this extension, load XS modules, etc... |
1468 | |
1469 | =item FULLPERLRUN |
1470 | |
1471 | Like PERLRUN, except it uses FULLPERL. |
1472 | |
1473 | =item FULLPERLRUNINST |
1474 | |
1475 | Like PERLRUNINST, except it uses FULLPERL. |
864a5fa8 |
1476 | |
762efda7 |
1477 | =item FUNCLIST |
1478 | |
1479 | This provides an alternate means to specify function names to be |
1480 | exported from the extension. Its value is a reference to an |
1481 | array of function names to be exported by the extension. These |
1482 | names are passed through unaltered to the linker options file. |
1483 | |
864a5fa8 |
1484 | =item H |
1485 | |
1486 | Ref to array of *.h file names. Similar to C. |
1487 | |
84902520 |
1488 | =item IMPORTS |
1489 | |
875fa795 |
1490 | This attribute is used to specify names to be imported into the |
69ff8adf |
1491 | extension. Takes a hash ref. |
1492 | |
1493 | It is only used on OS/2 and Win32. |
84902520 |
1494 | |
864a5fa8 |
1495 | =item INC |
1496 | |
1497 | Include file dirs eg: C<"-I/usr/5include -I/path/to/inc"> |
1498 | |
f1387719 |
1499 | =item INCLUDE_EXT |
1500 | |
1501 | Array of extension names to be included when doing a static build. |
1502 | MakeMaker will normally build with all of the installed extensions when |
1503 | doing a static build, and that is usually the desired behavior. If |
1504 | INCLUDE_EXT is present then MakeMaker will build only with those extensions |
1505 | which are explicitly mentioned. (e.g. [ qw( Socket POSIX ) ]) |
1506 | |
1507 | It is not necessary to mention DynaLoader or the current extension when |
1508 | filling in INCLUDE_EXT. If the INCLUDE_EXT is mentioned but is empty then |
1509 | only DynaLoader and the current extension will be included in the build. |
1510 | |
1511 | This attribute may be most useful when specified as a string on the |
de592821 |
1512 | command line: perl Makefile.PL INCLUDE_EXT='POSIX Socket Devel::Peek' |
f1387719 |
1513 | |
864a5fa8 |
1514 | =item INSTALLARCHLIB |
1515 | |
e05e23b1 |
1516 | Used by 'make install', which copies files from INST_ARCHLIB to this |
1517 | directory if INSTALLDIRS is set to perl. |
864a5fa8 |
1518 | |

1634 | =item LDDLFLAGS |
1635 | |
1636 | Any special flags that might need to be passed to ld to create a |
1637 | shared library suitable for dynamic loading. It is up to the makefile |

1640 | Defaults to $Config{lddlflags}. |
1641 | |
864a5fa8 |
1642 | =item LDFROM |
8e07c86e |
1643 | |

e35b8f9e |
1650 | LIB should only be set at C<perl Makefile.PL> time but is allowed as a |
f6d6199c |
1651 | MakeMaker argument. It has the effect of setting both INSTALLPRIVLIB |
1652 | and INSTALLSITELIB to that value regardless any explicit setting of |
1653 | those arguments (or of PREFIX). INSTALLARCHLIB and INSTALLSITEARCH |
1654 | are set to the corresponding architecture subdirectory. |

1655 | |
762efda7 |
1656 | =item LIBPERL_A |
1657 | |
1658 | The filename of the perllibrary that will be used together with this |

1662 | |
1663 | An anonymous array of alternative library |
1664 | specifications to be searched for (in order) until |
864a5fa8 |
1665 | at least one library is found. E.g. |
8e07c86e |
1666 | |
1667 | 'LIBS' => ["-lgdbm", "-ldbm -lfoo", "-L/path -ldbm.nfs"] |
1668 | |
1669 | Mind, that any element of the array |
1670 | contains a complete set of arguments for the ld |
1671 | command. So do not specify |
1672 | |
1673 | 'LIBS' => ["-ltcl", "-ltk", "-lX11"] |
1674 | |
1675 | See ODBM_File/Makefile.PL for an example, where an array is needed. If |
1676 | you specify a scalar as in |
1677 | |
1678 | 'LIBS' => "-ltcl -ltk -lX11" |
1679 | |
1680 | MakeMaker will turn it into an array with one element. |
1681 | |
864a5fa8 |
1682 | =item LINKTYPE |
8e07c86e |
1683 | |
e05e23b1 |
1684 | 'static' or 'dynamic' (default unless usedl=undef in |
1685 | config.sh). Should only be used to force static linking (also see |

1686 | linkext below). |
8e07c86e |
1687 | |
864a5fa8 |
1688 | =item MAKEAPERL |
8e07c86e |
1689 | |
864a5fa8 |
1690 | Boolean which tells MakeMaker, that it should include the rules to |
1691 | make a perl. This is handled automatically as a switch by |
1692 | MakeMaker. The user normally does not need it. |
8e07c86e |
1693 | |
479d2113 |
1694 | =item MAKEFILE_OLD |
1695 | |
1696 | When 'make clean' or similar is run, the $(FIRST_MAKEFILE) will be |
1697 | backed up at this location. |
8e07c86e |
1698 | |
479d2113 |
1699 | Defaults to $(FIRST_MAKEFILE).old or $(FIRST_MAKEFILE)_old on VMS. |

1700 | |
864a5fa8 |
1701 | =item MAN1PODS |
8e07c86e |
1702 | |
864a5fa8 |
1703 | Hashref of pod-containing files. MakeMaker will default this to all |
1704 | EXE_FILES files that include POD directives. The files listed |
1705 | here will be converted to man pages and installed as was requested |
1706 | at Configure time. |
8e07c86e |
1707 | |
864a5fa8 |
1708 | =item MAN3PODS |
8e07c86e |
1709 | |
bfa2a9ad |
1710 | Hashref that assigns to *.pm and *.pod files the files into which the |
1711 | manpages are to be written. MakeMaker parses all *.pod and *.pm files |
1712 | for POD directives. Files that contain POD will be the default keys of |
1713 | the MAN3PODS hashref. These will then be converted to man pages during |
1714 | C<make> and will be installed during C<make install>. |
8e07c86e |
1715 | |
864a5fa8 |
1716 | =item MAP_TARGET |
8e07c86e |
1717 | |
864a5fa8 |
1718 | If it is intended, that a new perl binary be produced, this variable |
1719 | may hold a name for that binary. Defaults to perl |
8e07c86e |
1720 | |
864a5fa8 |
1721 | =item MYEXTLIB |
4633a7c4 |
1722 | |
864a5fa8 |
1723 | If the extension links to a library that it builds set this to the |
1724 | name of the library (see SDBM_File) |
4633a7c4 |
1725 | |
864a5fa8 |
1726 | =item NAME |
8e07c86e |
1727 | |
864a5fa8 |
1728 | Perl module name for this extension (DBD::Oracle). This will default |
1729 | to the directory name but should be explicitly defined in the |
1730 | Makefile.PL. |
8e07c86e |
1731 | |
864a5fa8 |
1732 | =item NEEDS_LINKING |
8e07c86e |
1733 | |
a7665c5e |
1734 | MakeMaker will figure out if an extension contains linkable code |
864a5fa8 |
1735 | anywhere down the directory tree, and will set this variable |
a7665c5e |
1736 | accordingly, but you can speed it up a very little bit if you define |
864a5fa8 |
1737 | this boolean variable yourself. |
8e07c86e |
1738 | |
e05e23b1 |
1739 | =item NOECHO |
1740 | |
479d2113 |
1741 | Command so make does not print the literal commands its running. |
1742 | |
1743 | By setting it to an empty string you can generate a Makefile that |
1744 | prints all commands. Mainly used in debugging MakeMaker itself. |
1745 | |
1746 | Defaults to C<@>. |
e05e23b1 |
1747 | |
864a5fa8 |
1748 | =item NORECURS |
8e07c86e |
1749 | |
e05e23b1 |
1750 | Boolean. Attribute to inhibit descending into subdirectories. |
8e07c86e |
1751 | |
1df8d179 |
1752 | =item NO_META |
1753 | |
1754 | When true, suppresses the generation and addition to the MANIFEST of |
1755 | the META.yml module meta-data file during 'make distdir'. |
1756 | |
1757 | Defaults to false. |
1758 | |
762efda7 |
1759 | =item NO_VC |
1760 | |
a7665c5e |
1761 | In general, any generated Makefile checks for the current version of |
762efda7 |
1762 | MakeMaker and the version the Makefile was built under. If NO_VC is |
1763 | set, the version check is neglected. Do not write this into your |
1764 | Makefile.PL, use it interactively instead. |
1765 | |
864a5fa8 |
1766 | =item OBJECT |
8e07c86e |
1767 | |
864a5fa8 |
1768 | List of object files, defaults to '$(BASEEXT)$(OBJ_EXT)', but can be a long |
1769 | string containing all object files, e.g. "tkpBind.o |
1770 | tkpButton.o tkpCanvas.o" |
8e07c86e |
1771 | |
e35b8f9e |
1772 | (Where BASEEXT is the last component of NAME, and OBJ_EXT is $Config{obj_ext}.) |
1773 | |
3b03c0f3 |
1774 | =item OPTIMIZE |
1775 | |
1776 | Defaults to C<-O>. Set it to C<-g> to turn debugging on. The flag is |
1777 | passed to subdirectory makes. |
1778 | |
864a5fa8 |
1779 | =item PERL |
8e07c86e |
1780 | |
864a5fa8 |

8e07c86e |
1782 | |
da7f727a |
1783 | =item PERL_CORE |
1784 | |

1786 | distribution. |
1787 | |
864a5fa8 |
1788 | =item PERLMAINCC |
005c1a0e |
1789 | |
864a5fa8 |
1790 | The call to the program that is able to compile perlmain.c. Defaults |
1791 | to $(CC). |
005c1a0e |
1792 | |
864a5fa8 |
1793 | =item PERL_ARCHLIB |
005c1a0e |
1794 | |
da7f727a |
1795 | Same as for PERL_LIB, but for architecture dependent files. |
1796 | |
1797 | Used only when MakeMaker is building the extensions of the Perl core |
1798 | distribution (because normally $(PERL_ARCHLIB) is automatically in @INC, |
1799 | and adding it would get in the way of PERL5LIB). |
8e07c86e |
1800 | |
864a5fa8 |
1801 | =item PERL_LIB |
8e07c86e |
1802 | |
864a5fa8 |
1803 | Directory containing the Perl library to use. |
8e07c86e |
1804 | |
da7f727a |
1805 | Used only when MakeMaker is building the extensions of the Perl core |
1806 | distribution (because normally $(PERL_LIB) is automatically in @INC, |
1807 | and adding it would get in the way of PERL5LIB). |
1808 | |
e35b8f9e |
1809 | =item PERL_MALLOC_OK |
1810 | |
1811 | defaults to 0. Should be set to TRUE if the extension can work with |
1812 | the memory allocation routines substituted by the Perl malloc() subsystem. |
1813 | This should be applicable to most extensions with exceptions of those |
1814 | |
1815 | =over 4 |
1816 | |
1817 | =item * |
1818 | |
1819 | with bugs in memory allocations which are caught by Perl's malloc(); |
1820 | |
1821 | =item * |
1822 | |
1823 | which interact with the memory allocator in other ways than via |
1824 | malloc(), realloc(), free(), calloc(), sbrk() and brk(); |
1825 | |
1826 | =item * |
1827 | |
1828 | which rely on special alignment which is not provided by Perl's malloc(). |
1829 | |
1830 | =back |
1831 | |
1832 | B<NOTE.> Negligence to set this flag in I<any one> of loaded extension |
1833 | nullifies many advantages of Perl's malloc(), such as better usage of |
1834 | system resources, error detection, memory usage reporting, catchable failure |
1835 | of memory allocations, etc. |
1836 | |
479d2113 |
1837 | =item PERLPREFIX |
1838 | |
1839 | Directory under which core modules are to be installed. |
1840 | |
1841 | Defaults to $Config{installprefixexp} falling back to |
1842 | $Config{installprefix}, $Config{prefixexp} or $Config{prefix} should |
1843 | $Config{installprefixexp} not exist. |
1844 | |
1845 | Overridden by PREFIX. |
1846 | |
da7f727a |
1847 | =item PERLRUN |
1848 | |
75e2e551 |
1849 | Use this instead of $(PERL) when you wish to run perl. It will set up |
1850 | extra necessary flags for you. |
f6d6199c |
1851 | |
ffbaec2a |
1852 | =item PERLRUNINST |
f6d6199c |
1853 | |
75e2e551 |
1854 | Use this instead of $(PERL) when you wish to run perl to work with |
1855 | modules. It will add things like -I$(INST_ARCH) and other necessary |
1856 | flags so perl can see the modules you're about to install. |
f6d6199c |
1857 | |
864a5fa8 |
1858 | =item PERL_SRC |
8e07c86e |
1859 | |
864a5fa8 |
1860 | Directory containing the Perl source code (use of this should be |
1861 | avoided, it may be undefined) |
8e07c86e |
1862 | |
2366100d |
1863 | =item PERM_RW |
1864 | |
de592821 |
1865 | Desired permission for read/writable files. Defaults to C<644>. |
2366100d |
1866 | See also L<MM_Unix/perm_rw>. |
1867 | |
1868 | =item PERM_RWX |
1869 | |
1870 | Desired permission for executable files. Defaults to C<755>. |
1871 | See also L<MM_Unix/perm_rwx>. |
1872 | |
864a5fa8 |
1873 | =item PL_FILES |
8e07c86e |
1874 | |
7292dc67 |
1875 | MakeMaker can run programs to generate files for you at build time. |
1876 | By default any file named *.PL (except Makefile.PL and Build.PL) in |
1877 | the top level directory will be assumed to be a Perl program and run |
1878 | passing its own basename in as an argument. For example... |
1879 | |
1880 | perl foo.PL foo |
1881 | |
1882 | This behavior can be overridden by supplying your own set of files to |
1883 | search. PL_FILES accepts a hash ref, the key being the file to run |
1884 | and the value is passed in as the first argument when the PL file is run. |
1885 | |
41e5fcb0 |
1886 | PL_FILES => {'bin/foobar.PL' => 'bin/foobar'} |
7292dc67 |
1887 | |
1888 | Would run bin/foobar.PL like this: |
1889 | |
1890 | perl bin/foobar.PL bin/foobar |
1891 | |
1892 | If multiple files from one program are desired an array ref can be used. |
1893 | |
41e5fcb0 |
1894 | PL_FILES => {'bin/foobar.PL' => [qw(bin/foobar1 bin/foobar2)]} |
8e07c86e |
1895 | |
7292dc67 |
1896 | In this case the program will be run multiple times using each target file. |
8e07c86e |
1897 | |
7292dc67 |
1898 | perl bin/foobar.PL bin/foobar1 |
1899 | perl bin/foobar.PL bin/foobar2 |
3aa35033 |
1900 | |
4325052d |
1901 | PL files are normally run B<after> pm_to_blib and include INST_LIB and |
1902 | INST_ARCH in its C<@INC> so the just built modules can be |
1903 | accessed... unless the PL file is making a module (or anything else in |
1904 | PM) in which case it is run B<before> pm_to_blib and does not include |
1905 | INST_LIB and INST_ARCH in its C<@INC>. This apparently odd behavior |
1906 | is there for backwards compatibility (and its somewhat DWIM). |
41e5fcb0 |
1907 | |
8e07c86e |
1908 | |
864a5fa8 |
1909 | =item PM |
8e07c86e |
1910 | |
864a5fa8 |
1911 | Hashref of .pm files and *.pl files to be installed. e.g. |
8e07c86e |
1912 | |
864a5fa8 |
1913 | {'name_of_file.pm' => '$(INST_LIBDIR)/install_as.pm'} |
8e07c86e |
1914 | |
a3cb178b |
1915 | By default this will include *.pm and *.pl and the files found in |
1916 | the PMLIBDIRS directories. Defining PM in the |
864a5fa8 |
1917 | Makefile.PL will override PMLIBDIRS. |
8e07c86e |

8e07c86e |
1920 | |
864a5fa8 |
1921 | Ref to array of subdirectories containing library files. Defaults to |
a3cb178b |
1922 | [ 'lib', $(BASEEXT) ]. The directories will be scanned and I<any> files |
864a5fa8 |
1923 | they contain will be installed in the corresponding location in the |
1924 | library. A libscan() method can be used to alter the behaviour. |
1925 | Defining PM in the Makefile.PL will override PMLIBDIRS. |

1928 | |
131aa089 |
1929 | =item PM_FILTER |
1930 | |
1931 | A filter program, in the traditional Unix sense (input from stdin, output |
1932 | to stdout) that is passed on each .pm file during the build (in the |
1933 | pm_to_blib() phase). It is empty by default, meaning no filtering is done. |
1934 | |
1935 | Great care is necessary when defining the command if quoting needs to be |
1936 | done. For instance, you would need to say: |
1937 | |
1938 | {'PM_FILTER' => 'grep -v \\"^\\#\\"'} |
1939 | |
3c4b39be |
1940 | to remove all the leading comments on the fly during the build. The |
131aa089 |
1941 | extra \\ are necessary, unfortunately, because this variable is interpolated |
1942 | within the context of a Perl program built on the command line, and double |
1943 | quotes are what is used with the -e switch to build that command line. The |
1944 | # is escaped for the Makefile, since what is going to be generated will then |
1945 | be: |
1946 | |
1947 | PM_FILTER = grep -v \"^\#\" |
1948 | |
1949 | Without the \\ before the #, we'd have the start of a Makefile comment, |
1950 | and the macro would be incorrectly defined. |
1951 | |
2aea4d40 |
1952 | =item POLLUTE |
1953 | |
1954 | Release 5.005 grandfathered old global symbol names by providing preprocessor |
a7665c5e |
1955 | macros for extension source compatibility. As of release 5.6, these |
2aea4d40 |
1956 | preprocessor definitions are not available by default. The POLLUTE flag |
1957 | specifies that the old names should still be defined: |
1958 | |
1959 | perl Makefile.PL POLLUTE=1 |
1960 | |
1961 | Please inform the module author if this is necessary to successfully install |

1975 | This overrides all the default install locations. Man pages, |
1976 | libraries, scripts, etc... MakeMaker will try to make an educated |
1977 | guess about where to place things under the new PREFIX based on your |
1978 | Config defaults. Failing that, it will fall back to a structure |
1979 | which should be sensible for your platform. |
1980 | |
1981 | If you specify LIB or any INSTALL* variables they will not be effected |
1982 | by the PREFIX. |

0d8023a2 |
2077 | =item VERSION_FROM |
2078 | |
2079 | Instead of specifying the VERSION in the Makefile.PL you can let |
2080 | MakeMaker parse a file to determine the version number. The parsing |
2081 | routine requires that the file named by VERSION_FROM contains one |
2082 | single line to compute the version number. The first line in the file |
2083 | that contains the regular expression |
2084 | |
84902520 |
2085 | /([\$*])(([\w\:\']*)\bVERSION)\b.*\=/ |
0d8023a2 |

2087 | will be evaluated with eval() and the value of the named variable |
2088 | B<after> the eval() will be assigned to the VERSION attribute of the |

2096 | our $VERSION = 1.2.3; # new for perl5.6.0 |

e35b8f9e |
2104 | (Putting C<my> or C<local> on the preceding line will work o.k.) |
2105 | |
84902520 |
2106 | The file named in VERSION_FROM is not added as a dependency to |
2107 | Makefile. This is not really correct, but it would be a major pain |
2108 | during development to have to rewrite the Makefile for any smallish |
2109 | change in that file. If you want to make sure that the Makefile |
2110 | contains the correct VERSION macro after any change of the file, you |
2111 | would have to do something like |
2112 | |
2113 | depend => { Makefile => '$(VERSION_FROM)' } |

2221 | If you cannot achieve the desired Makefile behaviour by specifying |

e0678a30 |
2223 | Each subroutine returns the text it wishes to have written to |
005c1a0e |
2224 | the Makefile. To override a section of the Makefile you can |
2225 | either say: |
2226 | |
f6d6199c |
2227 | sub MY::c_o { "new literal text" } |
005c1a0e |
2228 | |
2229 | or you can edit the default by saying something like: |
2230 | |
e0678a30 |
2231 | package MY; # so that "SUPER" works right |
2232 | sub c_o { |
f6d6199c |

2238 | If you are running experiments with embedding perl as a library into |

2240 | better have a look at ExtUtils::Embed which is a collection of utilities |
2241 | for embedding. |
005c1a0e |
2242 | |
2243 | If you still need a different solution, try to develop another |

2261 | =head2 The End Of Cargo Cult Programming |
2262 | |
2263 | WriteMakefile() now does some basic sanity checks on its parameters to |
2264 | protect against typos and malformatted values. This means some things |
2265 | which happened to work in the past will now throw warnings and |
2266 | possibly produce internal errors. |

2283 | =head2 Hintsfile support |
2284 | |
2285 | MakeMaker.pm uses the architecture specific information from |
2286 | Config.pm. In addition it evaluates architecture specific hints files |
2287 | in a C<hints/> directory. The hints files are expected to be named |
2288 | like their counterparts in C<PERL_SRC/hints>, but with an C<.pl> file |
2289 | name extension (eg. C<next_3_2.pl>). They are simply C<eval>ed by |
2290 | MakeMaker within the WriteMakefile() subroutine, and can be used to |
2291 | execute commands as well as to include special variables. The rules |
2292 | which hintsfile is chosen are the same as in Configure. |
2293 | |
2294 | The hintsfile is eval()ed immediately after the arguments given to |
2295 | WriteMakefile are stuffed into a hash reference $self but before this |
2296 | reference becomes blessed. So if you want to do the equivalent to |
2297 | override or create an attribute you would say something like |
2298 | |
2299 | $self->{LIBS} = ['-ldbm -lucb -lc']; |

2321 | =item make distclean |
8e07c86e |
2322 | |
005c1a0e |
2323 | does a realclean first and then the distcheck. Note that this is not |
a7665c5e |
2324 | needed to build a new distribution as long as you are sure that the |
005c1a0e |
2325 | MANIFEST file is ok. |
2326 | |
2327 | =item make manifest |
8e07c86e |
2328 | |
005c1a0e |
2329 | rewrites the MANIFEST file, adding all remaining files found (See |
2330 | ExtUtils::Manifest::mkmanifest() for details) |
2331 | |
2332 | =item make distdir |
8e07c86e |
2333 | |
005c1a0e |
2334 | Copies all the files that are in the MANIFEST file to a newly created |
2335 | directory with the name C<$(DISTNAME)-$(VERSION)>. If that directory |
2336 | exists, it will be removed first. |
2337 | |
7292dc67 |
2338 | Additionally, it will create a META.yml module meta-data file in the |
2339 | distdir and add this to the distdir's MANFIEST. You can shut this |
2340 | behavior off with the NO_META flag. |

2342 | =item make disttest |
8e07c86e |
2343 | |
2344 | Makes a distdir first, and runs a C<perl Makefile.PL>, a make, and |
4633a7c4 |
2345 | a make test in that directory. |
8e07c86e |

2347 | =item make tardist |
8e07c86e |
2348 | |
3b03c0f3 |
2349 | First does a distdir. Then a command $(PREOP) which defaults to a null |
f1387719 |
2350 | command, followed by $(TOUNIX), which defaults to a null command under |
2351 | UNIX, and will convert files in distribution directory to UNIX format |
2352 | otherwise. Next it runs C<tar> on that directory into a tarfile and |
3b03c0f3 |
2353 | deletes the directory. Finishes with a command $(POSTOP) which |
2354 | defaults to a null command. |
005c1a0e |
2355 | |
2356 | =item make dist |
8e07c86e |
2357 | |
005c1a0e |
2358 | Defaults to $(DIST_DEFAULT) which in turn defaults to tardist. |
2359 | |
2360 | =item make uutardist |
8e07c86e |
2361 | |
005c1a0e |
2362 | Runs a tardist first and uuencodes the tarfile. |
2363 | |
2364 | =item make shdist |
8e07c86e |
2365 | |
3b03c0f3 |
2366 | First does a distdir. Then a command $(PREOP) which defaults to a null |
2367 | command. Next it runs C<shar> on that directory into a sharfile and |
2368 | deletes the intermediate directory again. Finishes with a command |
2369 | $(POSTOP) which defaults to a null command. Note: For shdist to work |
2370 | properly a C<shar> program that can handle directories is mandatory. |
2371 | |
2372 | =item make zipdist |
2373 | |
2374 | First does a distdir. Then a command $(PREOP) which defaults to a null |
2375 | command. Runs C<$(ZIP) $(ZIPFLAGS)> on that directory into a |
2376 | zipfile. Then deletes that directory. Finishes with a command |
2377 | $(POSTOP) which defaults to a null command. |
005c1a0e |
2378 | |
2379 | =item make ci |
8e07c86e |

2407 | =head2 Module Meta-Data |
2408 | |
2409 | Long plaguing users of MakeMaker based modules has been the problem of |
2410 | getting basic information about the module out of the sources |
2411 | I<without> running the F<Makefile.PL> and doing a bunch of messy |
2412 | heuristics on the resulting F<Makefile>. To this end a simple module |
2413 | meta-data file has been introduced, F<META.yml>. |
2414 | |
2415 | F<META.yml> is a YAML document (see http://www.yaml.org) containing |
2416 | basic information about the module (name, version, prerequisites...) |
2417 | in an easy to read format. The format is developed and defined by the |
64964e6d |
2418 | Module::Build developers (see |
2419 | http://module-build.sourceforge.net/META-spec.html) |
1df8d179 |
2420 | |
2421 | MakeMaker will automatically generate a F<META.yml> file for you and |
2422 | add it to your F<MANIFEST> as part of the 'distdir' target (and thus |
2423 | the 'dist' target). This is intended to seamlessly and rapidly |
2424 | populate CPAN with module meta-data. If you wish to shut this feature |
2425 | off, set the C<NO_META> C<WriteMakefile()> flag to true. |
2426 | |
2427 | |

2428 | =head2 Disabling an extension |
2429 | |
2430 | If some events detected in F<Makefile.PL> imply that there is no way |
2431 | to create the Module, but this is a normal state of things, then you |
2432 | can create a F<Makefile> which does nothing, but succeeds on all the |
2433 | "usual" build targets. To do so, use |
2434 | |
2435 | ExtUtils::MakeMaker::WriteEmptyMakefile(); |
2436 | |
2437 | instead of WriteMakefile(). |
2438 | |
2439 | This may be useful if other modules expect this module to be I<built> |
2440 | OK, as opposed to I<work> OK (say, this system-dependent module builds |
2441 | in a subdirectory of some other distribution, or is listed as a |
2442 | dependency in a CPAN::Bundle, but the functionality is supported by |
2443 | different means on the current architecture). |

2446 | |
2447 | =over 4 |
2448 | |
2449 | =item prompt |
2450 | |
2451 | my $value = prompt($message); |
2452 | my $value = prompt($message, $default); |
2453 | |
2454 | The C<prompt()> function provides an easy way to request user input |
2455 | used to write a makefile. It displays the $message as a prompt for |
2456 | input. If a $default is provided it will be used as a default. The |
2457 | function returns the $value selected by the user. |
2458 | |
2459 | If C<prompt()> detects that it is not running interactively and there |
2460 | is nothing on STDIN or if the PERL_MM_USE_DEFAULT environment variable |
2461 | is set to true, the $default will be used without prompting. This |
2462 | prevents automated processes from blocking on user input. |
2463 | |
2464 | If no $default is provided an empty string will be used instead. |
