309 | The extension you are trying to build apparently is rather old and |
310 | most probably outdated. We detect that from the fact, that a | |
311 | subroutine "writeMakefile" is called, and this subroutine is not | |
312 | supported anymore since about October 1994. | |
40000a8c | 313 | |
4633a7c4 LW |
314 | Please contact the author or look into CPAN (details about CPAN can be |
315 | found in the FAQ and at http:/www.perl.com) for a more recent version | |
316 | of the extension. If you're really desperate, you can try to change | |
317 | the subroutine name from writeMakefile to WriteMakefile and rerun | |
318 | 'perl Makefile.PL', but you're most probably left alone, when you do | |
319 | so. | |

005c1a0e AD |
901 | =head1 DESCRIPTION |
902 | ||
903 | This utility is designed to write a Makefile for an extension module | |
904 | from a Makefile.PL. It is based on the Makefile.SH model provided by | |
905 | Andy Dougherty and the perl5-porters. | |
906 | ||
907 | It splits the task of generating the Makefile into several subroutines | |
908 | that can be individually overridden. Each subroutine returns the text | |
909 | it wishes to have written to the Makefile. | |
910 | ||
f1387719 | 911 | MakeMaker is object oriented. Each directory below the current |
912 | directory that contains a Makefile.PL. Is treated as a separate | |
913 | object. This makes it possible to write an unlimited number of | |
914 | Makefiles with a single invocation of WriteMakefile(). | |
8e07c86e | 915 | |
f1387719 | 916 | =head2 How To Write A Makefile.PL |
8e07c86e | 917 | |
bab2b58e A |
918 | The short answer is: Don't. |
919 | ||
920 | Always begin with h2xs. | |
921 | Always begin with h2xs! | |
922 | ALWAYS BEGIN WITH H2XS! | |
923 | ||
924 | even if you're not building around a header file, and even if you | |
925 | don't have an XS component. | |
926 | ||
927 | Run h2xs(1) before you start thinking about writing a module. For so | |
928 | called pm-only modules that consist of C<*.pm> files only, h2xs has | |
929 | the C<-X> switch. This will generate dummy files of all kinds that are | |
930 | useful for the module developer. | |
8e07c86e | 931 | |
f1387719 | 932 | The medium answer is: |
8e07c86e | 933 | |
f1387719 | 934 | use ExtUtils::MakeMaker; |
935 | WriteMakefile( NAME => "Foo::Bar" ); | |
8e07c86e | 936 | |
bab2b58e | 937 | The long answer is the rest of the manpage :-) |
005c1a0e AD |
938 | |
939 | =head2 Default Makefile Behaviour | |
940 | ||
f1387719 | 941 | The generated Makefile enables the user of the extension to invoke |
005c1a0e AD |
942 | |
943 | perl Makefile.PL # optionally "perl Makefile.PL verbose" | |
944 | make | |
8e07c86e AD |
945 | make test # optionally set TEST_VERBOSE=1 |
946 | make install # See below | |
005c1a0e AD |
947 | |
948 | The Makefile to be produced may be altered by adding arguments of the | |
e05e23b1 | 949 | form C<KEY=VALUE>. E.g. |
005c1a0e | 950 | |
e05e23b1 | 951 | perl Makefile.PL PREFIX=/tmp/myperl5 |
005c1a0e AD |
952 | |
953 | Other interesting targets in the generated Makefile are | |
954 | ||
955 | make config # to check if the Makefile is up-to-date | |
8e07c86e AD |
956 | make clean # delete local temp files (Makefile gets renamed) |
957 | make realclean # delete derived files (including ./blib) | |
e05e23b1 | 958 | make ci # check in all the files in the MANIFEST file |
005c1a0e AD |
959 | make dist # see below the Distribution Support section |
960 | ||
e05e23b1 | 961 | =head2 make test |
962 | ||
bab2b58e | 963 | MakeMaker checks for the existence of a file named F<test.pl> in the |
e05e23b1 | 964 | current directory and if it exists it adds commands to the test target |
965 | of the generated Makefile that will execute the script with the proper | |
966 | set of perl C<-I> options. | |
967 | ||
968 | MakeMaker also checks for any files matching glob("t/*.t"). It will | |
969 | add commands to the test target of the generated Makefile that execute | |
970 | all matching files via the L<Test::Harness> module with the C<-I> | |
971 | switches set correctly. | |
972 | ||
bab2b58e A |
973 | =head2 make testdb |
974 | ||
975 | A useful variation of the above is the target C<testdb>. It runs the | |
976 | test under the Perl debugger (see L<perldebug>). If the file | |
977 | F<test.pl> exists in the current directory, it is used for the test. | |
978 | ||
979 | If you want to debug some other testfile, set C<TEST_FILE> variable | |
980 | thusly: | |
981 | ||
982 | make testdb TEST_FILE=t/mytest.t | |
983 | ||
984 | By default the debugger is called using C<-d> option to perl. If you | |
985 | want to specify some other option, set C<TESTDB_SW> variable: | |
986 | ||
987 | make testdb TESTDB_SW=-Dx | |
988 | ||
e05e23b1 | 989 | =head2 make install |
005c1a0e | 990 | |
8e07c86e | 991 | make alone puts all relevant files into directories that are named by |
cae6c631 JD |
992 | the macros INST_LIB, INST_ARCHLIB, INST_SCRIPT, INST_HTMLLIBDIR, |
993 | INST_HTMLSCRIPTDIR, INST_MAN1DIR, and INST_MAN3DIR. All these default | |
994 | to something below ./blib if you are I<not> building below the perl | |
995 | source directory. If you I<are> building below the perl source, | |
996 | INST_LIB and INST_ARCHLIB default to ../../lib, and INST_SCRIPT is not | |
997 | defined. | |
005c1a0e | 998 | |
e05e23b1 | 999 | The I<install> target of the generated Makefile copies the files found |
1000 | below each of the INST_* directories to their INSTALL* | |
1001 | counterparts. Which counterparts are chosen depends on the setting of | |
1002 | INSTALLDIRS according to the following table: | |
005c1a0e | 1003 | |
cae6c631 JD |
1004 | INSTALLDIRS set to |
1005 | perl site | |
e05e23b1 | 1006 | |
cae6c631 JD |
1007 | INST_ARCHLIB INSTALLARCHLIB INSTALLSITEARCH |
1008 | INST_LIB INSTALLPRIVLIB INSTALLSITELIB | |
1009 | INST_HTMLLIBDIR INSTALLHTMLPRIVLIBDIR INSTALLHTMLSITELIBDIR | |
1010 | INST_HTMLSCRIPTDIR INSTALLHTMLSCRIPTDIR | |
1011 | INST_BIN INSTALLBIN | |
1012 | INST_SCRIPT INSTALLSCRIPT | |
1013 | INST_MAN1DIR INSTALLMAN1DIR | |
1014 | INST_MAN3DIR INSTALLMAN3DIR | |
005c1a0e | 1015 | |
8e07c86e AD |
1016 | The INSTALL... macros in turn default to their %Config |
1017 | ($Config{installprivlib}, $Config{installarchlib}, etc.) counterparts. | |
005c1a0e | 1018 | |
3b03c0f3 | 1019 | You can check the values of these variables on your system with |
1020 | ||
bab2b58e | 1021 | perl '-V:install.*' |
3b03c0f3 | 1022 | |
f1387719 | 1023 | And to check the sequence in which the library directories are |
1024 | searched by perl, run | |
005c1a0e | 1025 | |
f1387719 | 1026 | perl -le 'print join $/, @INC' |
005c1a0e | 1027 | |
005c1a0e | 1028 | |
bab2b58e A |
1029 | =head2 PREFIX and LIB attribute |
1030 | ||
1031 | PREFIX and LIB can be used to set several INSTALL* attributes in one | |
1032 | go. The quickest way to install a module in a non-standard place might | |
1033 | be | |
1034 | ||
1035 | perl Makefile.PL LIB=~/lib | |
005c1a0e | 1036 | |
bab2b58e | 1037 | This will install the module's architecture-independent files into |
e35b8f9e | 1038 | ~/lib, the architecture-dependent files into ~/lib/$archname. |
bab2b58e A |
1039 | |
1040 | Another way to specify many INSTALL directories with a single | |
1041 | parameter is PREFIX. | |
005c1a0e | 1042 | |
8e07c86e | 1043 | perl Makefile.PL PREFIX=~ |
005c1a0e | 1044 | |
e35b8f9e JH |
1045 | This will replace the string specified by C<$Config{prefix}> in all |
1046 | C<$Config{install*}> values. | |
005c1a0e | 1047 | |
bab2b58e | 1048 | Note, that in both cases the tilde expansion is done by MakeMaker, not |
e35b8f9e JH |
1049 | by perl by default, nor by make. |
1050 | ||
1051 | Conflicts between parameters LIB, | |
1052 | PREFIX and the various INSTALL* arguments are resolved so that: | |
1053 | ||
1054 | =over 4 | |
1055 | ||
1056 | =item * | |
1057 | ||
1058 | setting LIB overrides any setting of INSTALLPRIVLIB, INSTALLARCHLIB, | |
1059 | INSTALLSITELIB, INSTALLSITEARCH (and they are not affected by PREFIX); | |
1060 | ||
1061 | =item * | |
1062 | ||
1063 | without LIB, setting PREFIX replaces the initial C<$Config{prefix}> | |
1064 | part of those INSTALL* arguments, even if the latter are explicitly | |
1065 | set (but are set to still start with C<$Config{prefix}>). | |
1066 | ||
1067 | =back | |
005c1a0e | 1068 | |
005c1a0e | 1069 | If the user has superuser privileges, and is not working on AFS |
e35b8f9e | 1070 | or relatives, then the defaults for |
f1387719 | 1071 | INSTALLPRIVLIB, INSTALLARCHLIB, INSTALLSCRIPT, etc. will be appropriate, |
005c1a0e AD |
1072 | and this incantation will be the best: |
1073 | ||
1074 | perl Makefile.PL; make; make test | |
1075 | make install | |
1076 | ||
8e07c86e | 1077 | make install per default writes some documentation of what has been |
e05e23b1 | 1078 | done into the file C<$(INSTALLARCHLIB)/perllocal.pod>. This feature |
1079 | can be bypassed by calling make pure_install. | |
8e07c86e AD |
1080 | |
1081 | =head2 AFS users | |
1082 | ||
1083 | will have to specify the installation directories as these most | |
1084 | probably have changed since perl itself has been installed. They will | |
1085 | have to do this by calling | |
1086 | ||
e05e23b1 | 1087 | perl Makefile.PL INSTALLSITELIB=/afs/here/today \ |
f1387719 | 1088 | INSTALLSCRIPT=/afs/there/now INSTALLMAN3DIR=/afs/for/manpages |
8e07c86e AD |
1089 | make |
1090 | ||
e05e23b1 | 1091 | Be careful to repeat this procedure every time you recompile an |
1092 | extension, unless you are sure the AFS installation directories are | |
1093 | still valid. | |
005c1a0e | 1094 | |
8e07c86e | 1095 | =head2 Static Linking of a new Perl Binary |
005c1a0e AD |
1096 | |
1097 | An extension that is built with the above steps is ready to use on | |
1098 | systems supporting dynamic loading. On systems that do not support | |
1099 | dynamic loading, any newly created extension has to be linked together | |
1100 | with the available resources. MakeMaker supports the linking process | |
1101 | by creating appropriate targets in the Makefile whenever an extension | |
1102 | is built. You can invoke the corresponding section of the makefile with | |
1103 | ||
1104 | make perl | |
1105 | ||
1106 | That produces a new perl binary in the current directory with all | |
da7f727a | 1107 | extensions linked in that can be found in INST_ARCHLIB, SITELIBEXP, |
e05e23b1 | 1108 | and PERL_ARCHLIB. To do that, MakeMaker writes a new Makefile, on |
1109 | UNIX, this is called Makefile.aperl (may be system dependent). If you | |
1110 | want to force the creation of a new perl, it is recommended, that you | |
1111 | delete this Makefile.aperl, so the directories are searched-through | |
1112 | for linkable libraries again. | |
005c1a0e AD |
1113 | |
1114 | The binary can be installed into the directory where perl normally | |
1115 | resides on your machine with | |
1116 | ||
1117 | make inst_perl | |
1118 | ||
1119 | To produce a perl binary with a different name than C<perl>, either say | |
1120 | ||
1121 | perl Makefile.PL MAP_TARGET=myperl | |
1122 | make myperl | |
1123 | make inst_perl | |
1124 | ||
1125 | or say | |
1126 | ||
1127 | perl Makefile.PL | |
1128 | make myperl MAP_TARGET=myperl | |
1129 | make inst_perl MAP_TARGET=myperl | |
1130 | ||
1131 | In any case you will be prompted with the correct invocation of the | |
1132 | C<inst_perl> target that installs the new binary into INSTALLBIN. | |
1133 | ||
8e07c86e AD |
1134 | make inst_perl per default writes some documentation of what has been |
1135 | done into the file C<$(INSTALLARCHLIB)/perllocal.pod>. This | |
1136 | can be bypassed by calling make pure_inst_perl. | |
005c1a0e | 1137 | |
e05e23b1 | 1138 | Warning: the inst_perl: target will most probably overwrite your |
1139 | existing perl binary. Use with care! | |
005c1a0e | 1140 | |
8e07c86e AD |
1141 | Sometimes you might want to build a statically linked perl although |
1142 | your system supports dynamic loading. In this case you may explicitly | |
1143 | set the linktype with the invocation of the Makefile.PL or make: | |
1144 | ||
1145 | perl Makefile.PL LINKTYPE=static # recommended | |
1146 | ||
1147 | or | |
1148 | ||
1149 | make LINKTYPE=static # works on most systems | |
1150 | ||
005c1a0e AD |
1151 | =head2 Determination of Perl Library and Installation Locations |
1152 | ||
1153 | MakeMaker needs to know, or to guess, where certain things are | |
e05e23b1 | 1154 | located. Especially INST_LIB and INST_ARCHLIB (where to put the files |
1155 | during the make(1) run), PERL_LIB and PERL_ARCHLIB (where to read | |
1156 | existing modules from), and PERL_INC (header files and C<libperl*.*>). | |
005c1a0e AD |

1158 | Extensions may be built either using the contents of the perl source | |
e05e23b1 | 1159 | directory tree or from the installed perl library. The recommended way |
1160 | is to build extensions after you have run 'make install' on perl | |
1161 | itself. You can do that in any directory on your hard disk that is not | |
1162 | below the perl source tree. The support for extensions below the ext | |
1163 | directory of the perl distribution is only good for the standard | |
1164 | extensions that come with perl. | |
005c1a0e AD |
1165 | |
1166 | If an extension is being built below the C<ext/> directory of the perl | |
e05e23b1 | 1167 | source then MakeMaker will set PERL_SRC automatically (e.g., |
1168 | C<../..>). If PERL_SRC is defined and the extension is recognized as | |
1169 | a standard extension, then other variables default to the following: | |
005c1a0e AD |
1170 | |
1171 | PERL_INC = PERL_SRC | |
1172 | PERL_LIB = PERL_SRC/lib | |
1173 | PERL_ARCHLIB = PERL_SRC/lib | |
1174 | INST_LIB = PERL_LIB | |
1175 | INST_ARCHLIB = PERL_ARCHLIB | |
1176 | ||
1177 | If an extension is being built away from the perl source then MakeMaker | |
1178 | will leave PERL_SRC undefined and default to using the installed copy | |
1179 | of the perl library. The other variables default to the following: | |
1180 | ||
e05e23b1 | 1181 | PERL_INC = $archlibexp/CORE |
1182 | PERL_LIB = $privlibexp | |
1183 | PERL_ARCHLIB = $archlibexp | |
1184 | INST_LIB = ./blib/lib | |
1185 | INST_ARCHLIB = ./blib/arch | |
005c1a0e AD |
1186 | |
1187 | If perl has not yet been installed then PERL_SRC can be defined on the | |
1188 | command line as shown in the previous section. | |

f1387719 | 1191 | =head2 Which architecture dependent directory? |
005c1a0e | 1192 | |
f1387719 | 1193 | If you don't want to keep the defaults for the INSTALL* macros, |
1194 | MakeMaker helps you to minimize the typing needed: the usual | |
1195 | relationship between INSTALLPRIVLIB and INSTALLARCHLIB is determined | |
1196 | by Configure at perl compilation time. MakeMaker supports the user who | |
1197 | sets INSTALLPRIVLIB. If INSTALLPRIVLIB is set, but INSTALLARCHLIB not, | |
1198 | then MakeMaker defaults the latter to be the same subdirectory of | |
1199 | INSTALLPRIVLIB as Configure decided for the counterparts in %Config , | |
1200 | otherwise it defaults to INSTALLPRIVLIB. The same relationship holds | |
1201 | for INSTALLSITELIB and INSTALLSITEARCH. | |
005c1a0e | 1202 | |
f1387719 | 1203 | MakeMaker gives you much more freedom than needed to configure |
1204 | internal variables and get different results. It is worth to mention, | |
1205 | that make(1) also lets you configure most of the variables that are | |
1206 | used in the Makefile. But in the majority of situations this will not | |
a7665c5e | 1207 | be necessary, and should only be done if the author of a package |
f1387719 | 1208 | recommends it (or you know what you're doing). |

1220 | ||
1221 | =item ABSTRACT_FROM | |
1222 | ||
1223 | Name of the file that contains the package description. MakeMaker looks | |
1224 | for a line in the POD matching /^($package\s-\s)(.*)/. This is typically | |
1225 | the first line in the "=head1 NAME" section. $2 becomes the abstract. | |
1226 | ||
e35b8f9e JH |
1227 | =item AUTHOR |
1228 | ||
1229 | String containing name (and email address) of package author(s). Is used | |

1234 | Used when creating PPD files for binary packages. It can be set to a | |
1235 | full or relative path or URL to the binary archive for a particular | |
1236 | architecture. For example: | |
1237 | ||
1238 | perl Makefile.PL BINARY_LOCATION=x86/Agent.tar.gz | |
1239 | ||
1240 | builds a PPD package that references a binary of the C<Agent> package, | |
20e08411 | 1241 | located in the C<x86> directory relative to the PPD itself. |

1323 | is ignored if INCLUDE_EXT is present. Consult INCLUDE_EXT for more | |
1324 | details. (e.g. [ qw( Socket POSIX ) ] ) | |
1325 | ||
1326 | This attribute may be most useful when specified as a string on the | |
de592821 | 1327 | command line: perl Makefile.PL EXCLUDE_EXT='Socket Safe' |
f1387719 | 1328 | |
864a5fa8 | 1329 | =item EXE_FILES |

1347 | This provides an alternate means to specify function names to be | |
1348 | exported from the extension. Its value is a reference to an | |
1349 | array of function names to be exported by the extension. These | |
1350 | names are passed through unaltered to the linker options file. | |
1351 | ||
864a5fa8 AD |
1352 | =item H |
1353 | ||

1378 | ||
f1387719 | 1379 | =item INCLUDE_EXT |
1380 | ||
1381 | Array of extension names to be included when doing a static build. | |
1382 | MakeMaker will normally build with all of the installed extensions when | |
1383 | doing a static build, and that is usually the desired behavior. If | |
1384 | INCLUDE_EXT is present then MakeMaker will build only with those extensions | |
1385 | which are explicitly mentioned. (e.g. [ qw( Socket POSIX ) ]) | |
1386 | ||
1387 | It is not necessary to mention DynaLoader or the current extension when | |
1388 | filling in INCLUDE_EXT. If the INCLUDE_EXT is mentioned but is empty then | |
1389 | only DynaLoader and the current extension will be included in the build. | |
1390 | ||
1391 | This attribute may be most useful when specified as a string on the | |
de592821 | 1392 | command line: perl Makefile.PL INCLUDE_EXT='POSIX Socket Devel::Peek' |
f1387719 | 1393 | |
864a5fa8 AD |

1519 | ||
1520 | An anonymous array of alternative library | |
1521 | specifications to be searched for (in order) until | |
864a5fa8 | 1522 | at least one library is found. E.g. |
8e07c86e AD |
1523 | |
1524 | 'LIBS' => ["-lgdbm", "-ldbm -lfoo", "-L/path -ldbm.nfs"] | |
1525 | ||
1526 | Mind, that any element of the array | |
1527 | contains a complete set of arguments for the ld | |
1528 | command. So do not specify | |
1529 | ||
1530 | 'LIBS' => ["-ltcl", "-ltk", "-lX11"] | |
1531 | ||
1532 | See ODBM_File/Makefile.PL for an example, where an array is needed. If | |
1533 | you specify a scalar as in | |
1534 | ||
1535 | 'LIBS' => "-ltcl -ltk -lX11" | |
1536 | ||
1537 | MakeMaker will turn it into an array with one element. | |

1557 | Hashref of pod-containing files. MakeMaker will default this to all |
1558 | EXE_FILES files that include POD directives. The files listed | |
1559 | here will be converted to man pages and installed as was requested | |
1560 | at Configure time. | |
8e07c86e | 1561 | |
864a5fa8 | 1562 | =item MAN3PODS |
8e07c86e | 1563 | |
bfa2a9ad A |
1564 | Hashref that assigns to *.pm and *.pod files the files into which the |
1565 | manpages are to be written. MakeMaker parses all *.pod and *.pm files | |
1566 | for POD directives. Files that contain POD will be the default keys of | |
1567 | the MAN3PODS hashref. These will then be converted to man pages during | |
1568 | C<make> and will be installed during C<make install>. | |
8e07c86e | 1569 | |
864a5fa8 | 1570 | =item MAP_TARGET |
8e07c86e | 1571 | |
864a5fa8 AD |
1572 | If it is intended, that a new perl binary be produced, this variable |

8e07c86e | 1574 | |
864a5fa8 | 1575 | =item MYEXTLIB |
4633a7c4 | 1576 | |
864a5fa8 AD |
1577 | If the extension links to a library that it builds set this to the |
1578 | name of the library (see SDBM_File) | |
4633a7c4 | 1579 | |
864a5fa8 | 1580 | =item NAME |
8e07c86e | 1581 | |
864a5fa8 AD |
1582 | Perl module name for this extension (DBD::Oracle). This will default |
1583 | to the directory name but should be explicitly defined in the | |
1584 | Makefile.PL. | |
8e07c86e | 1585 | |
864a5fa8 | 1586 | =item NEEDS_LINKING |
8e07c86e | 1587 | |
a7665c5e | 1588 | MakeMaker will figure out if an extension contains linkable code |
864a5fa8 | 1589 | anywhere down the directory tree, and will set this variable |
a7665c5e | 1590 | accordingly, but you can speed it up a very little bit if you define |
864a5fa8 | 1591 | this boolean variable yourself. |
8e07c86e | 1592 | |
e05e23b1 | 1593 | =item NOECHO |
1594 | ||
f1387719 | 1595 | Defaults to C<@>. By setting it to an empty string you can generate a |
e05e23b1 | 1596 | Makefile that echos all commands. Mainly used in debugging MakeMaker |
1597 | itself. | |
1598 | ||
864a5fa8 | 1599 | =item NORECURS |
8e07c86e | 1600 | |
e05e23b1 | 1601 | Boolean. Attribute to inhibit descending into subdirectories. |
8e07c86e | 1602 | |
762efda7 JD |
1603 | =item NO_VC |
1604 | ||
a7665c5e | 1605 | In general, any generated Makefile checks for the current version of |
762efda7 JD |
1606 | MakeMaker and the version the Makefile was built under. If NO_VC is |
1607 | set, the version check is neglected. Do not write this into your | |
1608 | Makefile.PL, use it interactively instead. | |

864a5fa8 | 1610 | =item OBJECT |
8e07c86e | 1611 | |
864a5fa8 AD |
1612 | List of object files, defaults to '$(BASEEXT)$(OBJ_EXT)', but can be a long |
1613 | string containing all object files, e.g. "tkpBind.o | |
1614 | tkpButton.o tkpCanvas.o" | |
8e07c86e | 1615 | |

1641 | Used only when MakeMaker is building the extensions of the Perl core | |
1642 | distribution (because normally $(PERL_ARCHLIB) is automatically in @INC, | |

1652 | ||
e35b8f9e JH |
1653 | =item PERL_MALLOC_OK |
1654 | ||
1655 | defaults to 0. Should be set to TRUE if the extension can work with | |
1656 | the memory allocation routines substituted by the Perl malloc() subsystem. | |
1657 | This should be applicable to most extensions with exceptions of those | |
1658 | ||

1676 | B<NOTE.> Negligence to set this flag in I<any one> of loaded extension | |
1677 | nullifies many advantages of Perl's malloc(), such as better usage of | |
1678 | system resources, error detection, memory usage reporting, catchable failure | |

da7f727a JH |
1681 | =item PERLRUN |
1682 | ||
cf699fa3 MS |
1683 | Use this instead of $(PERL) or $(FULLPERL) when you wish to run perl. |
1684 | It will set up extra necessary flags for you. | |
1685 | ||
ffbaec2a | 1686 | =item PERLRUNINST |
cf699fa3 MS |
1687 | |
1688 | Use this instead of $(PERL) or $(FULLPERL) when you wish to run | |
1689 | perl to work with modules. It will add things like -I$(INST_ARCH) | |
1690 | and other necessary flags. | |
1691 | ||
864a5fa8 | 1692 | =item PERL_SRC |
8e07c86e | 1693 | |
864a5fa8 AD |

1706 | ||
864a5fa8 | 1707 | =item PL_FILES |
8e07c86e | 1708 | |
864a5fa8 AD |
1709 | Ref to hash of files to be processed as perl programs. MakeMaker |
1710 | will default to any found *.PL file (except Makefile.PL) being keys | |
1711 | and the basename of the file being the value. E.g. | |
8e07c86e | 1712 | |
864a5fa8 | 1713 | {'foobar.PL' => 'foobar'} |
8e07c86e | 1714 | |
864a5fa8 | 1715 | The *.PL files are expected to produce output to the target files |
3aa35033 GS |
1716 | themselves. If multiple files can be generated from the same *.PL |
1717 | file then the value in the hash can be a reference to an array of | |
1718 | target file names. E.g. | |
1719 | ||
1720 | {'foobar.PL' => ['foobar1','foobar2']} | |
8e07c86e | 1721 | |
864a5fa8 | 1722 | =item PM |
8e07c86e | 1723 | |
864a5fa8 | 1724 | Hashref of .pm files and *.pl files to be installed. e.g. |
8e07c86e | 1725 | |
864a5fa8 | 1726 | {'name_of_file.pm' => '$(INST_LIBDIR)/install_as.pm'} |
8e07c86e | 1727 | |
a3cb178b GS |
1728 | By default this will include *.pm and *.pl and the files found in |
1729 | the PMLIBDIRS directories. Defining PM in the | |
864a5fa8 | 1730 | Makefile.PL will override PMLIBDIRS. |
8e07c86e | 1731 | |
864a5fa8 | 1732 | =item PMLIBDIRS |
8e07c86e | 1733 | |
864a5fa8 | 1734 | Ref to array of subdirectories containing library files. Defaults to |
a3cb178b | 1735 | [ 'lib', $(BASEEXT) ]. The directories will be scanned and I<any> files |
864a5fa8 AD |
1736 | they contain will be installed in the corresponding location in the |
1737 | library. A libscan() method can be used to alter the behaviour. | |
1738 | Defining PM in the Makefile.PL will override PMLIBDIRS. | |
8e07c86e | 1739 | |
e35b8f9e JH |
1740 | (Where BASEEXT is the last component of NAME.) |
1741 | ||
131aa089 RM |
1742 | =item PM_FILTER |
1743 | ||
1744 | A filter program, in the traditional Unix sense (input from stdin, output | |
1745 | to stdout) that is passed on each .pm file during the build (in the | |
1746 | pm_to_blib() phase). It is empty by default, meaning no filtering is done. | |
1747 | ||
1748 | Great care is necessary when defining the command if quoting needs to be | |
1749 | done. For instance, you would need to say: | |
1750 | ||
1751 | {'PM_FILTER' => 'grep -v \\"^\\#\\"'} | |
1752 | ||
1753 | to remove all the leading coments on the fly during the build. The | |
1754 | extra \\ are necessary, unfortunately, because this variable is interpolated | |
1755 | within the context of a Perl program built on the command line, and double | |
1756 | quotes are what is used with the -e switch to build that command line. The | |
1757 | # is escaped for the Makefile, since what is going to be generated will then | |
1758 | be: | |
1759 | ||
1760 | PM_FILTER = grep -v \"^\#\" | |
1761 | ||
1762 | Without the \\ before the #, we'd have the start of a Makefile comment, | |
1763 | and the macro would be incorrectly defined. | |
1764 | ||
2aea4d40 JD |
1765 | =item POLLUTE |
1766 | ||
1767 | Release 5.005 grandfathered old global symbol names by providing preprocessor | |
a7665c5e | 1768 | macros for extension source compatibility. As of release 5.6, these |
2aea4d40 JD |
1769 | preprocessor definitions are not available by default. The POLLUTE flag |
1770 | specifies that the old names should still be defined: | |
1771 | ||
1772 | perl Makefile.PL POLLUTE=1 | |
1773 | ||
1774 | Please inform the module author if this is necessary to successfully install | |
a7665c5e | 1775 | a module under 5.6 or later. |
2aea4d40 | 1776 | |

864a5fa8 | 1786 | =item PREFIX |
8e07c86e | 1787 | |
864a5fa8 | 1788 | Can be used to set the three INSTALL* attributes in one go (except for |
e05e23b1 | 1789 | probably INSTALLMAN1DIR, if it is not below PREFIX according to |
1790 | %Config). They will have PREFIX as a common directory node and will | |
1791 | branch from that node into lib/, lib/ARCHNAME or whatever Configure | |
1792 | decided at the build time of your perl (unless you override one of | |
1793 | them, of course). | |
a4260cbc | 1794 | |
f1387719 | 1795 | =item PREREQ_PM |
8e07c86e | 1796 | |
f1387719 | 1797 | Hashref: Names of modules that need to be available to run this |
1798 | extension (e.g. Fcntl for SDBM_File) are the keys of the hash and the | |
1799 | desired version is the value. If the required version number is 0, we | |
1800 | only check if any version is installed already. | |
8e07c86e | 1801 | |
b2340c53 K |
1802 | =item PREREQ_FATAL |
1803 | ||
1804 | Bool. If this parameter is true, failing to have the required modules | |
1805 | (or the right versions thereof) will be fatal. perl Makefile.PL will die | |
1806 | with the proper message. | |
1807 | ||
1808 | Note: see L<Test::Harness> for a shortcut for stopping tests early if | |
1809 | you are missing dependencies. | |
1810 | ||
1811 | Do I<not> use this parameter for simple requirements, which could be resolved | |
1812 | at a later time, e.g. after an unsuccessful B<make test> of your module. | |
1813 | ||
1814 | It is I<extremely> rare to have to use C<PREREQ_FATAL> at all! | |
1815 | ||
88d69b28 JH |
1816 | =item PREREQ_PRINT |
1817 | ||
1818 | Bool. If this parameter is true, the prerequisites will be printed to | |
1819 | stdout and MakeMaker will exit. The output format is | |
1820 | ||
1821 | $PREREQ_PM = { | |
1822 | 'A::B' => Vers1, | |

864a5fa8 | 1833 | =item SKIP |
8e07c86e | 1834 | |
da7f727a | 1835 | Arrayref. E.g. [qw(name1 name2)] skip (do not write) sections of the |
a7665c5e GS |
1836 | Makefile. Caution! Do not use the SKIP attribute for the negligible |
1837 | speedup. It may seriously damage the resulting Makefile. Only use it | |
f1387719 | 1838 | if you really need it. |
8e07c86e | 1839 | |
da7f727a JH |
1840 | =item TEST_LIBS |
1841 | ||
cf699fa3 MS |
1842 | The set of -I's necessary to run a "make test". Use as: |

1844 | ||
864a5fa8 | 1845 | =item TYPEMAPS |
8e07c86e | 1846 | |
864a5fa8 AD |
1847 | Ref to array of typemap file names. Use this when the typemaps are |
1848 | in some directory other than the current directory or when they are | |
1849 | not named B<typemap>. The last typemap in the list takes | |
1850 | precedence. A typemap in the current directory has highest | |
1851 | precedence, even if it isn't listed in TYPEMAPS. The default system | |
1852 | typemap has lowest precedence. | |
8e07c86e | 1853 | |
864a5fa8 | 1854 | =item VERSION |
8e07c86e | 1855 | |
864a5fa8 AD |
1856 | Your version number for distributing the package. This defaults to |
1857 | 0.1. | |
8e07c86e | 1858 | |
0d8023a2 | 1859 | =item VERSION_FROM |
1860 | ||
1861 | Instead of specifying the VERSION in the Makefile.PL you can let | |
1862 | MakeMaker parse a file to determine the version number. The parsing | |
1863 | routine requires that the file named by VERSION_FROM contains one | |
1864 | single line to compute the version number. The first line in the file | |
1865 | that contains the regular expression | |
1866 | ||
84902520 | 1867 | /([\$*])(([\w\:\']*)\bVERSION)\b.*\=/ |
0d8023a2 | 1868 | |
1869 | will be evaluated with eval() and the value of the named variable | |
1870 | B<after> the eval() will be assigned to the VERSION attribute of the | |
1871 | MakeMaker object. The following lines will be parsed o.k.: | |
1872 | ||
1873 | $VERSION = '1.00'; | |
84902520 | 1874 | *VERSION = \'1.01'; |

e35b8f9e | 1878 | our $VERSION = 1.2.3; # new for perl5.6.0 |
0d8023a2 | 1879 | |
1880 | but these will fail: | |

1884 | local $FOO::VERSION = '1.30'; | |

e35b8f9e JH |
1886 | (Putting C<my> or C<local> on the preceding line will work o.k.) |
1887 | ||
84902520 TB |
1888 | The file named in VERSION_FROM is not added as a dependency to |
1889 | Makefile. This is not really correct, but it would be a major pain | |
1890 | during development to have to rewrite the Makefile for any smallish | |
1891 | change in that file. If you want to make sure that the Makefile | |
1892 | contains the correct VERSION macro after any change of the file, you | |
1893 | would have to do something like | |
1894 | ||
1895 | depend => { Makefile => '$(VERSION_FROM)' } | |
1896 | ||
1897 | See attribute C<depend> below. | |

8e07c86e | 1900 | |
864a5fa8 | 1901 | Hashref of .xs files. MakeMaker will default this. e.g. |

1950 | If you specify COMPRESS, then SUFFIX should also be altered, as it is | |
1951 | needed to tell make the target file of the compression. Setting | |
1952 | DIST_CP to ln can be useful, if you need to preserve the timestamps on | |
1953 | your files. DIST_CP can take the values 'cp', which copies the file, | |
1954 | 'ln', which links the file, and 'best' which copies symbolic links and | |
1955 | links the rest. Default is 'best'. | |

1991 | =head2 Overriding MakeMaker Methods | |
1992 | ||
1993 | If you cannot achieve the desired Makefile behaviour by specifying | |
1994 | attributes you may define private subroutines in the Makefile.PL. | |
1995 | Each subroutines returns the text it wishes to have written to | |
1996 | the Makefile. To override a section of the Makefile you can | |
1997 | either say: | |
1998 | ||
1999 | sub MY::c_o { "new literal text" } | |
2000 | ||
2001 | or you can edit the default by saying something like: | |
2002 | ||
8e07c86e | 2003 | sub MY::c_o { |
14870ecd CS |
2004 | package MY; # so that "SUPER" works right |
2005 | my $inherited = shift->SUPER::c_o(@_); | |
f1387719 | 2006 | $inherited =~ s/old text/new text/; |
2007 | $inherited; | |

2010 | If you are running experiments with embedding perl as a library into |
2011 | other applications, you might find MakeMaker is not sufficient. You'd | |
2012 | better have a look at ExtUtils::Embed which is a collection of utilities | |
2013 | for embedding. | |
005c1a0e AD |
2014 | |
2015 | If you still need a different solution, try to develop another | |
bdda3fbd PJ |
2016 | subroutine that fits your needs and submit the diffs to |
2017 | F<perl5-porters@perl.org> or F<comp.lang.perl.moderated> as appropriate. | |
005c1a0e | 2018 | |
3b03c0f3 | 2019 | For a complete description of all MakeMaker methods see L<ExtUtils::MM_Unix>. |
2020 | ||
2021 | Here is a simple example of how to add a new target to the generated | |
2022 | Makefile: | |
2023 | ||
2024 | sub MY::postamble { | |
2025 | ' | |
2026 | $(MYEXTLIB): sdbm/Makefile | |
2027 | cd sdbm && $(MAKE) all | |
2028 | '; | |
2029 | } | |
2030 | ||
2031 | ||
f1387719 | 2032 | =head2 Hintsfile support |
2033 | ||
2034 | MakeMaker.pm uses the architecture specific information from | |
2035 | Config.pm. In addition it evaluates architecture specific hints files | |
2036 | in a C<hints/> directory. The hints files are expected to be named | |
2037 | like their counterparts in C<PERL_SRC/hints>, but with an C<.pl> file | |
2038 | name extension (eg. C<next_3_2.pl>). They are simply C<eval>ed by | |
2039 | MakeMaker within the WriteMakefile() subroutine, and can be used to | |
2040 | execute commands as well as to include special variables. The rules | |
2041 | which hintsfile is chosen are the same as in Configure. | |
2042 | ||
2043 | The hintsfile is eval()ed immediately after the arguments given to | |
2044 | WriteMakefile are stuffed into a hash reference $self but before this | |
2045 | reference becomes blessed. So if you want to do the equivalent to | |
2046 | override or create an attribute you would say something like | |
2047 | ||
2048 | $self->{LIBS} = ['-ldbm -lucb -lc']; | |
2049 | ||

2050 | =head2 Distribution Support |
2051 | ||
2052 | For authors of extensions MakeMaker provides several Makefile | |
2053 | targets. Most of the support comes from the ExtUtils::Manifest module, | |
2054 | where additional documentation can be found. | |

4633a7c4 LW |
2064 | =item make skipcheck |

2068 | details) | |
2069 | ||
005c1a0e | 2070 | =item make distclean |
8e07c86e | 2071 | |
005c1a0e | 2072 | does a realclean first and then the distcheck. Note that this is not |
a7665c5e | 2073 | needed to build a new distribution as long as you are sure that the |

2080 | ||
2081 | =item make distdir | |
8e07c86e | 2082 | |
005c1a0e AD |
2083 | Copies all the files that are in the MANIFEST file to a newly created |
2084 | directory with the name C<$(DISTNAME)-$(VERSION)>. If that directory | |
2085 | exists, it will be removed first. | |

8e07c86e AD |
2087 | =item make disttest |

005c1a0e | 2092 | =item make tardist |
8e07c86e | 2093 | |
3b03c0f3 | 2094 | First does a distdir. Then a command $(PREOP) which defaults to a null |
f1387719 | 2095 | command, followed by $(TOUNIX), which defaults to a null command under |
2096 | UNIX, and will convert files in distribution directory to UNIX format | |
2097 | otherwise. Next it runs C<tar> on that directory into a tarfile and | |
3b03c0f3 | 2098 | deletes the directory. Finishes with a command $(POSTOP) which |
2099 | defaults to a null command. | |
005c1a0e AD |
2100 | |
2101 | =item make dist | |
8e07c86e | 2102 | |
005c1a0e AD |
2103 | Defaults to $(DIST_DEFAULT) which in turn defaults to tardist. |
2104 | ||
2105 | =item make uutardist | |
8e07c86e | 2106 | |
005c1a0e AD |
2107 | Runs a tardist first and uuencodes the tarfile. |
2108 | ||
2109 | =item make shdist | |
8e07c86e | 2110 | |
3b03c0f3 | 2111 | First does a distdir. Then a command $(PREOP) which defaults to a null |
2112 | command. Next it runs C<shar> on that directory into a sharfile and | |
2113 | deletes the intermediate directory again. Finishes with a command | |
2114 | $(POSTOP) which defaults to a null command. Note: For shdist to work | |
2115 | properly a C<shar> program that can handle directories is mandatory. | |
2116 | ||
2117 | =item make zipdist | |
2118 | ||
2119 | First does a distdir. Then a command $(PREOP) which defaults to a null | |
2120 | command. Runs C<$(ZIP) $(ZIPFLAGS)> on that directory into a | |
2121 | zipfile. Then deletes that directory. Finishes with a command | |
2122 | $(POSTOP) which defaults to a null command. | |
005c1a0e AD |
2123 | |
2124 | =item make ci | |
8e07c86e AD |
2125 | |
2126 | Does a $(CI) and a $(RCS_LABEL) on all files in the MANIFEST file. | |

2129 | |
2130 | Customization of the dist targets can be done by specifying a hash | |

2132 | following parameters are recognized: | |
2133 | ||
8e07c86e | 2134 | CI ('ci -u') |

2151 | =head2 Disabling an extension |
2152 | ||
2153 | If some events detected in F<Makefile.PL> imply that there is no way | |
2154 | to create the Module, but this is a normal state of things, then you | |
2155 | can create a F<Makefile> which does nothing, but succeeds on all the | |
2156 | "usual" build targets. To do so, use | |
2157 | ||
2158 | ExtUtils::MakeMaker::WriteEmptyMakefile(); | |
2159 | ||
2160 | instead of WriteMakefile(). | |
2161 | ||
2162 | This may be useful if other modules expect this module to be I<built> | |
2163 | OK, as opposed to I<work> OK (say, this system-dependent module builds | |
2164 | in a subdirectory of some other distribution, or is listed as a | |
2165 | dependency in a CPAN::Bundle, but the functionality is supported by | |
2166 | different means on the current architecture). | |
