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340 | most probably outdated.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

005c1a0e |
838 | =head1 DESCRIPTION |
839 | |
840 | This utility is designed to write a Makefile for an extension module |
841 | from a Makefile.PL. It is based on the Makefile.SH model provided by |
842 | Andy Dougherty and the perl5-porters. |
843 | |
844 | It splits the task of generating the Makefile into several subroutines |
845 | that can be individually overridden. Each subroutine returns the text |
846 | it wishes to have written to the Makefile. |
847 | |
f1387719 |
848 | MakeMaker is object oriented. Each directory below the current |
849 | directory that contains a Makefile.PL. Is treated as a separate |
850 | object. This makes it possible to write an unlimited number of |
851 | Makefiles with a single invocation of WriteMakefile(). |

853 | =head2 How To Write A Makefile.PL |
8e07c86e |
854 | |
bab2b58e |
855 | The short answer is: Don't. |
856 | |
857 | Always begin with h2xs. |
858 | Always begin with h2xs! |
859 | ALWAYS BEGIN WITH H2XS! |
860 | |
861 | even if you're not building around a header file, and even if you |
862 | don't have an XS component. |
863 | |
864 | Run h2xs(1) before you start thinking about writing a module. For so |
865 | called pm-only modules that consist of C<*.pm> files only, h2xs has |
866 | the C<-X> switch. This will generate dummy files of all kinds that are |
867 | useful for the module developer. |
8e07c86e |
868 | |
f1387719 |
869 | The medium answer is: |
8e07c86e |
870 | |
f1387719 |
871 | use ExtUtils::MakeMaker; |
872 | WriteMakefile( NAME => "Foo::Bar" ); |
8e07c86e |
873 | |
bab2b58e |
874 | The long answer is the rest of the manpage :-) |
005c1a0e |
875 | |
876 | =head2 Default Makefile Behaviour |
877 | |
f1387719 |
878 | The generated Makefile enables the user of the extension to invoke |
005c1a0e |
879 | |
880 | perl Makefile.PL # optionally "perl Makefile.PL verbose" |
881 | make |
8e07c86e |
882 | make test # optionally set TEST_VERBOSE=1 |
883 | make install # See below |
005c1a0e |
884 | |
885 | The Makefile to be produced may be altered by adding arguments of the |
e05e23b1 |
886 | form C<KEY=VALUE>. E.g. |
005c1a0e |
887 | |
e05e23b1 |
888 | perl Makefile.PL PREFIX=/tmp/myperl5 |
005c1a0e |
889 | |
890 | Other interesting targets in the generated Makefile are |
891 | |
892 | make config # to check if the Makefile is up-to-date |
8e07c86e |
893 | make clean # delete local temp files (Makefile gets renamed) |
894 | make realclean # delete derived files (including ./blib) |
e05e23b1 |
895 | make ci # check in all the files in the MANIFEST file |
005c1a0e |
896 | make dist # see below the Distribution Support section |
897 | |
e05e23b1 |
898 | =head2 make test |
899 | |
bab2b58e |
900 | MakeMaker checks for the existence of a file named F<test.pl> in the |
e05e23b1 |
901 | current directory and if it exists it adds commands to the test target |
902 | of the generated Makefile that will execute the script with the proper |
903 | set of perl C<-I> options. |
904 | |
905 | MakeMaker also checks for any files matching glob("t/*.t"). It will |
906 | add commands to the test target of the generated Makefile that execute |
907 | all matching files via the L<Test::Harness> module with the C<-I> |
908 | switches set correctly. |
909 | |
bab2b58e |
910 | =head2 make testdb |
911 | |
912 | A useful variation of the above is the target C<testdb>. It runs the |
913 | test under the Perl debugger (see L<perldebug>). If the file |
914 | F<test.pl> exists in the current directory, it is used for the test. |
915 | |
916 | If you want to debug some other testfile, set C<TEST_FILE> variable |
917 | thusly: |
918 | |
919 | make testdb TEST_FILE=t/mytest.t |
920 | |
921 | By default the debugger is called using C<-d> option to perl. If you |
922 | want to specify some other option, set C<TESTDB_SW> variable: |
923 | |
924 | make testdb TESTDB_SW=-Dx |
925 | |
e05e23b1 |
926 | =head2 make install |
005c1a0e |
927 | |
8e07c86e |
928 | make alone puts all relevant files into directories that are named by |
f1387719 |
929 | the macros INST_LIB, INST_ARCHLIB, INST_SCRIPT, INST_MAN1DIR, and |
930 | INST_MAN3DIR. All these default to something below ./blib if you are |
931 | I<not> building below the perl source directory. If you I<are> |
8e07c86e |
932 | building below the perl source, INST_LIB and INST_ARCHLIB default to |
5b195008 |
933 | ../../lib, and INST_SCRIPT is not defined. |
005c1a0e |
934 | |
e05e23b1 |
935 | The I<install> target of the generated Makefile copies the files found |
936 | below each of the INST_* directories to their INSTALL* |
937 | counterparts. Which counterparts are chosen depends on the setting of |
938 | INSTALLDIRS according to the following table: |
005c1a0e |
939 | |
e05e23b1 |
940 | INSTALLDIRS set to |
941 | perl site |
942 | |
e05e23b1 |
943 | INST_ARCHLIB INSTALLARCHLIB INSTALLSITEARCH |
3b03c0f3 |
944 | INST_LIB INSTALLPRIVLIB INSTALLSITELIB |
f1387719 |
945 | INST_BIN INSTALLBIN |
946 | INST_SCRIPT INSTALLSCRIPT |
e05e23b1 |
947 | INST_MAN1DIR INSTALLMAN1DIR |
948 | INST_MAN3DIR INSTALLMAN3DIR |
005c1a0e |
949 | |
8e07c86e |
950 | The INSTALL... macros in turn default to their %Config |
951 | ($Config{installprivlib}, $Config{installarchlib}, etc.) counterparts. |
005c1a0e |
952 | |
3b03c0f3 |
953 | You can check the values of these variables on your system with |
954 | |
bab2b58e |
955 | perl '-V:install.*' |
3b03c0f3 |
956 | |
f1387719 |
957 | And to check the sequence in which the library directories are |
958 | searched by perl, run |
005c1a0e |
959 | |
f1387719 |
960 | perl -le 'print join $/, @INC' |
005c1a0e |
961 | |
005c1a0e |
962 | |
bab2b58e |
963 | =head2 PREFIX and LIB attribute |
964 | |
965 | PREFIX and LIB can be used to set several INSTALL* attributes in one |
966 | go. The quickest way to install a module in a non-standard place might |
967 | be |
968 | |
969 | perl Makefile.PL LIB=~/lib |
005c1a0e |
970 | |
bab2b58e |
971 | This will install the module's architecture-independent files into |
972 | ~/lib, the architecture-dependent files into ~/lib/$archname/auto. |
973 | |
974 | Another way to specify many INSTALL directories with a single |
975 | parameter is PREFIX. |
005c1a0e |
976 | |
8e07c86e |
977 | perl Makefile.PL PREFIX=~ |
005c1a0e |
978 | |
0d8023a2 |
979 | This will replace the string specified by $Config{prefix} in all |
980 | $Config{install*} values. |
005c1a0e |
981 | |
bab2b58e |
982 | Note, that in both cases the tilde expansion is done by MakeMaker, not |
983 | by perl by default, nor by make. Conflicts between parmeters LIB, |
984 | PREFIX and the various INSTALL* arguments are resolved so that |
985 | XXX |
005c1a0e |
986 | |
005c1a0e |
987 | If the user has superuser privileges, and is not working on AFS |
988 | (Andrew File System) or relatives, then the defaults for |
f1387719 |
989 | INSTALLPRIVLIB, INSTALLARCHLIB, INSTALLSCRIPT, etc. will be appropriate, |
005c1a0e |
990 | and this incantation will be the best: |
991 | |
992 | perl Makefile.PL; make; make test |
993 | make install |
994 | |
8e07c86e |
995 | make install per default writes some documentation of what has been |
e05e23b1 |
996 | done into the file C<$(INSTALLARCHLIB)/perllocal.pod>. This feature |
997 | can be bypassed by calling make pure_install. |
8e07c86e |
998 | |
999 | =head2 AFS users |
1000 | |
1001 | will have to specify the installation directories as these most |
1002 | probably have changed since perl itself has been installed. They will |
1003 | have to do this by calling |
1004 | |
e05e23b1 |
1005 | perl Makefile.PL INSTALLSITELIB=/afs/here/today \ |
f1387719 |
1006 | INSTALLSCRIPT=/afs/there/now INSTALLMAN3DIR=/afs/for/manpages |
8e07c86e |
1007 | make |
1008 | |
e05e23b1 |
1009 | Be careful to repeat this procedure every time you recompile an |
1010 | extension, unless you are sure the AFS installation directories are |
1011 | still valid. |
005c1a0e |
1012 | |
8e07c86e |
1013 | =head2 Static Linking of a new Perl Binary |
005c1a0e |
1014 | |
1015 | An extension that is built with the above steps is ready to use on |
1016 | systems supporting dynamic loading. On systems that do not support |
1017 | dynamic loading, any newly created extension has to be linked together |
1018 | with the available resources. MakeMaker supports the linking process |
1019 | by creating appropriate targets in the Makefile whenever an extension |
1020 | is built. You can invoke the corresponding section of the makefile with |
1021 | |
1022 | make perl |
1023 | |
1024 | That produces a new perl binary in the current directory with all |
e05e23b1 |
1025 | extensions linked in that can be found in INST_ARCHLIB , SITELIBEXP, |
1026 | and PERL_ARCHLIB. To do that, MakeMaker writes a new Makefile, on |
1027 | UNIX, this is called Makefile.aperl (may be system dependent). If you |
1028 | want to force the creation of a new perl, it is recommended, that you |
1029 | delete this Makefile.aperl, so the directories are searched-through |
1030 | for linkable libraries again. |
005c1a0e |
1031 | |
1032 | The binary can be installed into the directory where perl normally |
1033 | resides on your machine with |
1034 | |
1035 | make inst_perl |
1036 | |
1037 | To produce a perl binary with a different name than C<perl>, either say |
1038 | |
1039 | perl Makefile.PL MAP_TARGET=myperl |
1040 | make myperl |
1041 | make inst_perl |
1042 | |
1043 | or say |
1044 | |
1045 | perl Makefile.PL |
1046 | make myperl MAP_TARGET=myperl |
1047 | make inst_perl MAP_TARGET=myperl |
1048 | |
1049 | In any case you will be prompted with the correct invocation of the |
1050 | C<inst_perl> target that installs the new binary into INSTALLBIN. |
1051 | |
8e07c86e |
1052 | make inst_perl per default writes some documentation of what has been |
1053 | done into the file C<$(INSTALLARCHLIB)/perllocal.pod>. This |
1054 | can be bypassed by calling make pure_inst_perl. |
005c1a0e |
1055 | |
e05e23b1 |
1056 | Warning: the inst_perl: target will most probably overwrite your |
1057 | existing perl binary. Use with care! |
005c1a0e |
1058 | |
8e07c86e |
1059 | Sometimes you might want to build a statically linked perl although |
1060 | your system supports dynamic loading. In this case you may explicitly |
1061 | set the linktype with the invocation of the Makefile.PL or make: |
1062 | |
1063 | perl Makefile.PL LINKTYPE=static # recommended |
1064 | |
1065 | or |
1066 | |
1067 | make LINKTYPE=static # works on most systems |
1068 | |
005c1a0e |
1069 | =head2 Determination of Perl Library and Installation Locations |
1070 | |
1071 | MakeMaker needs to know, or to guess, where certain things are |
e05e23b1 |
1072 | located. Especially INST_LIB and INST_ARCHLIB (where to put the files |
1073 | during the make(1) run), PERL_LIB and PERL_ARCHLIB (where to read |
1074 | existing modules from), and PERL_INC (header files and C<libperl*.*>). |
005c1a0e |
1075 | |
1076 | Extensions may be built either using the contents of the perl source |
e05e23b1 |
1077 | directory tree or from the installed perl library. The recommended way |
1078 | is to build extensions after you have run 'make install' on perl |
1079 | itself. You can do that in any directory on your hard disk that is not |
1080 | below the perl source tree. The support for extensions below the ext |
1081 | directory of the perl distribution is only good for the standard |
1082 | extensions that come with perl. |
005c1a0e |
1083 | |
1084 | If an extension is being built below the C<ext/> directory of the perl |
e05e23b1 |
1085 | source then MakeMaker will set PERL_SRC automatically (e.g., |
1086 | C<../..>). If PERL_SRC is defined and the extension is recognized as |
1087 | a standard extension, then other variables default to the following: |
005c1a0e |
1088 | |
1089 | PERL_INC = PERL_SRC |
1090 | PERL_LIB = PERL_SRC/lib |
1091 | PERL_ARCHLIB = PERL_SRC/lib |
1092 | INST_LIB = PERL_LIB |
1093 | INST_ARCHLIB = PERL_ARCHLIB |
1094 | |
1095 | If an extension is being built away from the perl source then MakeMaker |
1096 | will leave PERL_SRC undefined and default to using the installed copy |
1097 | of the perl library. The other variables default to the following: |
1098 | |
e05e23b1 |
1099 | PERL_INC = $archlibexp/CORE |
1100 | PERL_LIB = $privlibexp |
1101 | PERL_ARCHLIB = $archlibexp |
1102 | INST_LIB = ./blib/lib |
1103 | INST_ARCHLIB = ./blib/arch |
005c1a0e |
1104 | |
1105 | If perl has not yet been installed then PERL_SRC can be defined on the |
1106 | command line as shown in the previous section. |
1107 | |
005c1a0e |
1108 | |
f1387719 |
1109 | =head2 Which architecture dependent directory? |
005c1a0e |
1110 | |
f1387719 |
1111 | If you don't want to keep the defaults for the INSTALL* macros, |
1112 | MakeMaker helps you to minimize the typing needed: the usual |
1113 | relationship between INSTALLPRIVLIB and INSTALLARCHLIB is determined |
1114 | by Configure at perl compilation time. MakeMaker supports the user who |
1115 | sets INSTALLPRIVLIB. If INSTALLPRIVLIB is set, but INSTALLARCHLIB not, |
1116 | then MakeMaker defaults the latter to be the same subdirectory of |
1117 | INSTALLPRIVLIB as Configure decided for the counterparts in %Config , |
1118 | otherwise it defaults to INSTALLPRIVLIB. The same relationship holds |
1119 | for INSTALLSITELIB and INSTALLSITEARCH. |
005c1a0e |
1120 | |
f1387719 |
1121 | MakeMaker gives you much more freedom than needed to configure |
1122 | internal variables and get different results. It is worth to mention, |
1123 | that make(1) also lets you configure most of the variables that are |
1124 | used in the Makefile. But in the majority of situations this will not |
1125 | be necessary, and should only be done, if the author of a package |
1126 | recommends it (or you know what you're doing). |

1128 | =head2 Using Attributes and Parameters |
005c1a0e |
1129 | |
1130 | The following attributes can be specified as arguments to WriteMakefile() |
1131 | or as NAME=VALUE pairs on the command line: |
1132 | |
8e07c86e |
1133 | =cut |
005c1a0e |
1134 | |
864a5fa8 |
1135 | # The following "=item C" is used by the attrib_help routine |
8e07c86e |
1136 | # likewise the "=back" below. So be careful when changing it! |
1137 | |
1138 | =over 2 |
1139 | |
864a5fa8 |
1140 | =item C |
8e07c86e |
1141 | |
864a5fa8 |
1142 | Ref to array of *.c file names. Initialised from a directory scan |
1143 | and the values portion of the XS attribute hash. This is not |
1144 | currently used by MakeMaker but may be handy in Makefile.PLs. |
8e07c86e |
1145 | |
864a5fa8 |
1146 | =item CONFIG |
8e07c86e |
1147 | |
864a5fa8 |
1148 | Arrayref. E.g. [qw(archname manext)] defines ARCHNAME & MANEXT from |
1149 | config.sh. MakeMaker will add to CONFIG the following values anyway: |
1150 | ar |
1151 | cc |
1152 | cccdlflags |
1153 | ccdlflags |
1154 | dlext |
1155 | dlsrc |

8e07c86e |
1166 | |
1167 | =item CONFIGURE |
1168 | |
e05e23b1 |
1169 | CODE reference. The subroutine should return a hash reference. The |
1fef88e7 |

8e07c86e |
1171 | be determined by some evaluation method. |

1189 | Hashref of symbol names for routines to be made available as |
1190 | universal symbols. Each key/value pair consists of the package name |
1191 | and an array of routine names in that package. Used only under AIX |
1192 | (export lists) and VMS (linker options) at present. The routine |
1193 | names supplied will be expanded in the same way as XSUB names are |
1194 | expanded by the XS() macro. Defaults to |
8e07c86e |
1195 | |
864a5fa8 |
1196 | {"$(NAME)" => ["boot_$(NAME)" ] } |
8e07c86e |
1197 | |

1200 | {"RPC" => [qw( boot_rpcb rpcb_gettime getnetconfigent )], |
1201 | "NetconfigPtr" => [ 'DESTROY'] } |
8e07c86e |
1202 | |
864a5fa8 |

1205 | Array of symbol names for variables to be made available as |
1206 | universal symbols. Used only under AIX (export lists) and VMS |
1207 | (linker options) at present. Defaults to []. (e.g. [ qw( |
1208 | Foo_version Foo_numstreams Foo_tree ) ]) |
8e07c86e |
1209 | |
f1387719 |
1210 | =item EXCLUDE_EXT |
1211 | |
1212 | Array of extension names to exclude when doing a static build. This |
1213 | is ignored if INCLUDE_EXT is present. Consult INCLUDE_EXT for more |
1214 | details. (e.g. [ qw( Socket POSIX ) ] ) |
1215 | |
1216 | This attribute may be most useful when specified as a string on the |
1217 | commandline: perl Makefile.PL EXCLUDE_EXT='Socket Safe' |
1218 | |
864a5fa8 |
1219 | =item EXE_FILES |
8e07c86e |
1220 | |
864a5fa8 |
1221 | Ref to array of executable files. The files will be copied to the |
f1387719 |
1222 | INST_SCRIPT directory. Make realclean will delete them from there |
864a5fa8 |
1223 | again. |
8e07c86e |
1224 | |
3b03c0f3 |
1225 | =item NO_VC |
1226 | |
1227 | In general any generated Makefile checks for the current version of |
1228 | MakeMaker and the version the Makefile was built under. If NO_VC is |
1229 | set, the version check is neglected. Do not write this into your |
1230 | Makefile.PL, use it interactively instead. |
1231 | |
864a5fa8 |
1232 | =item FIRST_MAKEFILE |
1233 | |
1234 | The name of the Makefile to be produced. Defaults to the contents of |
1235 | MAKEFILE, but can be overridden. This is used for the second Makefile |
1236 | that will be produced for the MAP_TARGET. |
1237 | |
1238 | =item FULLPERL |

1249 | |
f1387719 |
1250 | =item INCLUDE_EXT |
1251 | |
1252 | Array of extension names to be included when doing a static build. |
1253 | MakeMaker will normally build with all of the installed extensions when |
1254 | doing a static build, and that is usually the desired behavior. If |
1255 | INCLUDE_EXT is present then MakeMaker will build only with those extensions |
1256 | which are explicitly mentioned. (e.g. [ qw( Socket POSIX ) ]) |
1257 | |
1258 | It is not necessary to mention DynaLoader or the current extension when |
1259 | filling in INCLUDE_EXT. If the INCLUDE_EXT is mentioned but is empty then |
1260 | only DynaLoader and the current extension will be included in the build. |
1261 | |
1262 | This attribute may be most useful when specified as a string on the |
1263 | commandline: perl Makefile.PL INCLUDE_EXT='POSIX Socket Devel::Peek' |
1264 | |
864a5fa8 |
1265 | =item INSTALLARCHLIB |
1266 | |

1274 | =item INSTALLDIRS |
1275 | |
1276 | Determines which of the two sets of installation directories to |
1277 | choose: installprivlib and installarchlib versus installsitelib and |
1278 | installsitearch. The first pair is chosen with INSTALLDIRS=perl, the |
1279 | second with INSTALLDIRS=site. Default is site. |
8e07c86e |
1280 | |
1281 | =item INSTALLMAN1DIR |
1282 | |
864a5fa8 |
1283 | This directory gets the man pages at 'make install' time. Defaults to |

1295 | |
f1387719 |
1296 | =item INSTALLSCRIPT |
1297 | |
1298 | Used by 'make install' which copies files from INST_SCRIPT to this |

1304 | directory if INSTALLDIRS is set to site (default). |
1305 | |
1306 | =item INSTALLSITEARCH |
1307 | |
1308 | Used by 'make install', which copies files from INST_ARCHLIB to this |
1309 | directory if INSTALLDIRS is set to site (default). |

f1387719 |
1338 | =item INST_SCRIPT |
1339 | |
1340 | Directory, where executable files should be installed during |
1341 | 'make'. Defaults to "./blib/bin", just to have a dummy location during |
1342 | testing. make install will copy the files in INST_SCRIPT to |
1343 | INSTALLSCRIPT. |
1344 | |
864a5fa8 |
1345 | =item LDFROM |
8e07c86e |
1346 | |
864a5fa8 |
1347 | defaults to "$(OBJECT)" and is used in the ld command to specify |
1348 | what files to link/load from (also see dynamic_lib below for how to |
1349 | specify ld flags) |
8e07c86e |
1350 | |
864a5fa8 |
1351 | =item LIBPERL_A |
8e07c86e |
1352 | |
864a5fa8 |
1353 | The filename of the perllibrary that will be used together with this |
1354 | extension. Defaults to libperl.a. |
8e07c86e |
1355 | |
bab2b58e |
1356 | =item LIB |
1357 | |
1358 | LIB can only be set at C<perl Makefile.PL> time. It has the effect of |
1359 | setting both INSTALLPRIVLIB and INSTALLSITELIB to that value regardless any |
1360 | |
8e07c86e |
1361 | =item LIBS |
1362 | |
1363 | An anonymous array of alternative library |
1364 | specifications to be searched for (in order) until |
864a5fa8 |
1365 | at least one library is found. E.g. |
8e07c86e |
1366 | |
1367 | 'LIBS' => ["-lgdbm", "-ldbm -lfoo", "-L/path -ldbm.nfs"] |
1368 | |
1369 | Mind, that any element of the array |
1370 | contains a complete set of arguments for the ld |
1371 | command. So do not specify |
1372 | |
1373 | 'LIBS' => ["-ltcl", "-ltk", "-lX11"] |
1374 | |
1375 | See ODBM_File/Makefile.PL for an example, where an array is needed. If |
1376 | you specify a scalar as in |
1377 | |
1378 | 'LIBS' => "-ltcl -ltk -lX11" |
1379 | |
1380 | MakeMaker will turn it into an array with one element. |
1381 | |
864a5fa8 |
1382 | =item LINKTYPE |
8e07c86e |
1383 | |
e05e23b1 |
1384 | 'static' or 'dynamic' (default unless usedl=undef in |
1385 | config.sh). Should only be used to force static linking (also see |
864a5fa8 |
1386 | linkext below). |
8e07c86e |
1387 | |
864a5fa8 |
1388 | =item MAKEAPERL |
8e07c86e |
1389 | |
864a5fa8 |
1390 | Boolean which tells MakeMaker, that it should include the rules to |
1391 | make a perl. This is handled automatically as a switch by |
1392 | MakeMaker. The user normally does not need it. |
8e07c86e |
1393 | |
864a5fa8 |
1394 | =item MAKEFILE |
8e07c86e |
1395 | |

8e07c86e |
1397 | |
864a5fa8 |
1398 | =item MAN1PODS |
8e07c86e |
1399 | |
864a5fa8 |
1400 | Hashref of pod-containing files. MakeMaker will default this to all |
1401 | EXE_FILES files that include POD directives. The files listed |
1402 | here will be converted to man pages and installed as was requested |
1403 | at Configure time. |
8e07c86e |
1404 | |
864a5fa8 |
1405 | =item MAN3PODS |
8e07c86e |
1406 | |
864a5fa8 |
1407 | Hashref of .pm and .pod files. MakeMaker will default this to all |
1408 | .pod and any .pm files that include POD directives. The files listed |
1409 | here will be converted to man pages and installed as was requested |
1410 | at Configure time. |
8e07c86e |
1411 | |
864a5fa8 |
1412 | =item MAP_TARGET |
8e07c86e |
1413 | |
864a5fa8 |
1414 | If it is intended, that a new perl binary be produced, this variable |
1415 | may hold a name for that binary. Defaults to perl |
8e07c86e |
1416 | |
864a5fa8 |
1417 | =item MYEXTLIB |
4633a7c4 |
1418 | |
864a5fa8 |
1419 | If the extension links to a library that it builds set this to the |
1420 | name of the library (see SDBM_File) |
4633a7c4 |
1421 | |
864a5fa8 |
1422 | =item NAME |
8e07c86e |
1423 | |
864a5fa8 |
1424 | Perl module name for this extension (DBD::Oracle). This will default |
1425 | to the directory name but should be explicitly defined in the |
1426 | Makefile.PL. |
8e07c86e |
1427 | |
864a5fa8 |
1428 | =item NEEDS_LINKING |
8e07c86e |
1429 | |
864a5fa8 |
1430 | MakeMaker will figure out, if an extension contains linkable code |
1431 | anywhere down the directory tree, and will set this variable |
1432 | accordingly, but you can speed it up a very little bit, if you define |
1433 | this boolean variable yourself. |
8e07c86e |
1434 | |
e05e23b1 |
1435 | =item NOECHO |
1436 | |
f1387719 |
1437 | Defaults to C<@>. By setting it to an empty string you can generate a |
e05e23b1 |
1438 | Makefile that echos all commands. Mainly used in debugging MakeMaker |
1439 | itself. |
1440 | |
864a5fa8 |
1441 | =item NORECURS |
8e07c86e |
1442 | |
e05e23b1 |

1445 | =item OBJECT |
8e07c86e |
1446 | |
864a5fa8 |
1447 | List of object files, defaults to '$(BASEEXT)$(OBJ_EXT)', but can be a long |
1448 | string containing all object files, e.g. "tkpBind.o |
1449 | tkpButton.o tkpCanvas.o" |
8e07c86e |
1450 | |
3b03c0f3 |
1451 | =item OPTIMIZE |
1452 | |
1453 | Defaults to C<-O>. Set it to C<-g> to turn debugging on. The flag is |
1454 | passed to subdirectory makes. |
1455 | |
864a5fa8 |
1456 | =item PERL |
8e07c86e |
1457 | |
864a5fa8 |
1458 | Perl binary for tasks that can be done by miniperl |
8e07c86e |
1459 | |
864a5fa8 |
1460 | =item PERLMAINCC |
005c1a0e |
1461 | |
864a5fa8 |
1462 | The call to the program that is able to compile perlmain.c. Defaults |
1463 | to $(CC). |
005c1a0e |
1464 | |
864a5fa8 |
1465 | =item PERL_ARCHLIB |
005c1a0e |
1466 | |
864a5fa8 |
1467 | Same as above for architecture dependent files |
8e07c86e |
1468 | |
864a5fa8 |
1469 | =item PERL_LIB |
8e07c86e |
1470 | |

1472 | |
864a5fa8 |
1473 | =item PERL_SRC |
8e07c86e |
1474 | |
864a5fa8 |
1475 | Directory containing the Perl source code (use of this should be |
1476 | avoided, it may be undefined) |
8e07c86e |
1477 | |
864a5fa8 |
1478 | =item PL_FILES |
8e07c86e |
1479 | |
864a5fa8 |
1480 | Ref to hash of files to be processed as perl programs. MakeMaker |
1481 | will default to any found *.PL file (except Makefile.PL) being keys |
1482 | and the basename of the file being the value. E.g. |
8e07c86e |
1483 | |
864a5fa8 |
1484 | {'foobar.PL' => 'foobar'} |
8e07c86e |
1485 | |
864a5fa8 |
1486 | The *.PL files are expected to produce output to the target files |
1487 | themselves. |
8e07c86e |
1488 | |
864a5fa8 |
1489 | =item PM |
8e07c86e |
1490 | |
864a5fa8 |
1491 | Hashref of .pm files and *.pl files to be installed. e.g. |
8e07c86e |
1492 | |
864a5fa8 |
1493 | {'name_of_file.pm' => '$(INST_LIBDIR)/install_as.pm'} |
8e07c86e |
1494 | |
864a5fa8 |
1495 | By default this will include *.pm and *.pl. If a lib directory |
1496 | exists and is not listed in DIR (above) then any *.pm and *.pl files |
1497 | it contains will also be included by default. Defining PM in the |
1498 | Makefile.PL will override PMLIBDIRS. |
8e07c86e |
1499 | |
864a5fa8 |
1500 | =item PMLIBDIRS |
8e07c86e |
1501 | |
864a5fa8 |
1502 | Ref to array of subdirectories containing library files. Defaults to |
1503 | [ 'lib', $(BASEEXT) ]. The directories will be scanned and any files |
1504 | they contain will be installed in the corresponding location in the |
1505 | library. A libscan() method can be used to alter the behaviour. |
1506 | Defining PM in the Makefile.PL will override PMLIBDIRS. |
8e07c86e |
1507 | |
864a5fa8 |
1508 | =item PREFIX |
8e07c86e |
1509 | |
864a5fa8 |
1510 | Can be used to set the three INSTALL* attributes in one go (except for |
e05e23b1 |
1511 | probably INSTALLMAN1DIR, if it is not below PREFIX according to |
1512 | %Config). They will have PREFIX as a common directory node and will |
1513 | branch from that node into lib/, lib/ARCHNAME or whatever Configure |
1514 | decided at the build time of your perl (unless you override one of |
1515 | them, of course). |
8e07c86e |
1516 | |
f1387719 |
1517 | =item PREREQ_PM |
8e07c86e |
1518 | |
f1387719 |
1519 | Hashref: Names of modules that need to be available to run this |
1520 | extension (e.g. Fcntl for SDBM_File) are the keys of the hash and the |
1521 | desired version is the value. If the required version number is 0, we |
1522 | only check if any version is installed already. |
8e07c86e |
1523 | |
864a5fa8 |
1524 | =item SKIP |
8e07c86e |
1525 | |
864a5fa8 |
1526 | Arryref. E.g. [qw(name1 name2)] skip (do not write) sections of the |
f1387719 |
1527 | Makefile. Caution! Do not use the SKIP attribute for the neglectible |
1528 | speedup. It may seriously damage the resulting Makefile. Only use it, |
1529 | if you really need it. |
8e07c86e |
1530 | |
864a5fa8 |
1531 | =item TYPEMAPS |
8e07c86e |
1532 | |
864a5fa8 |
1533 | Ref to array of typemap file names. Use this when the typemaps are |
1534 | in some directory other than the current directory or when they are |
1535 | not named B<typemap>. The last typemap in the list takes |
1536 | precedence. A typemap in the current directory has highest |
1537 | precedence, even if it isn't listed in TYPEMAPS. The default system |
1538 | typemap has lowest precedence. |
8e07c86e |
1539 | |
864a5fa8 |
1540 | =item VERSION |
8e07c86e |
1541 | |
864a5fa8 |
1542 | Your version number for distributing the package. This defaults to |
1543 | 0.1. |
8e07c86e |
1544 | |
0d8023a2 |
1545 | =item VERSION_FROM |
1546 | |
1547 | Instead of specifying the VERSION in the Makefile.PL you can let |
1548 | MakeMaker parse a file to determine the version number. The parsing |
1549 | routine requires that the file named by VERSION_FROM contains one |
1550 | single line to compute the version number. The first line in the file |
1551 | that contains the regular expression |
1552 | |
5b195008 |
1553 | /\$(([\w\:\']*)\bVERSION)\b.*\=/ |
0d8023a2 |
1554 | |
1555 | will be evaluated with eval() and the value of the named variable |
1556 | B<after> the eval() will be assigned to the VERSION attribute of the |
1557 | MakeMaker object. The following lines will be parsed o.k.: |
1558 | |
1559 | $VERSION = '1.00'; |
bab2b58e |
1560 | ( $VERSION ) = '$Revision: 1.208 $ ' =~ /\$Revision:\s+([^\s]+)/; |
0d8023a2 |
1561 | $FOO::VERSION = '1.10'; |
1562 | |
1563 | but these will fail: |
1564 | |
1565 | my $VERSION = '1.01'; |
1566 | local $VERSION = '1.02'; |

1622 | If you specify COMPRESS, then SUFFIX should also be altered, as it is |
1623 | needed to tell make the target file of the compression. Setting |
1624 | DIST_CP to ln can be useful, if you need to preserve the timestamps on |
1625 | your files. DIST_CP can take the values 'cp', which copies the file, |
1626 | 'ln', which links the file, and 'best' which copies symbolic links and |

1669 | =head2 Overriding MakeMaker Methods |
1670 | |
1671 | If you cannot achieve the desired Makefile behaviour by specifying |
1672 | attributes you may define private subroutines in the Makefile.PL. |
1673 | Each subroutines returns the text it wishes to have written to |
1674 | the Makefile. To override a section of the Makefile you can |
1675 | either say: |
1676 | |
1677 | sub MY::c_o { "new literal text" } |
1678 | |
1679 | or you can edit the default by saying something like: |
1680 | |
8e07c86e |
1681 | sub MY::c_o { |
f1387719 |
1682 | my($inherited) = shift->SUPER::c_o(@_); |
1683 | $inherited =~ s/old text/new text/; |
1684 | $inherited; |
8e07c86e |
1685 | } |
1686 | |
f1387719 |
1687 | If you running experiments with embedding perl as a library into other |
1688 | applications, you might find MakeMaker not sufficient. You'd better |
1689 | have a look at ExtUtils::embed which is a collection of utilities for |
1690 | embedding. |
005c1a0e |
1691 | |
1692 | If you still need a different solution, try to develop another |
1693 | subroutine, that fits your needs and submit the diffs to |
8e07c86e |
1694 | F<perl5-porters@nicoh.com> or F<comp.lang.perl.misc> as appropriate. |
005c1a0e |
1695 | |
3b03c0f3 |
1696 | For a complete description of all MakeMaker methods see L<ExtUtils::MM_Unix>. |
1697 | |
1698 | Here is a simple example of how to add a new target to the generated |
1699 | Makefile: |
1700 | |
1701 | sub MY::postamble { |
1702 | ' |
1703 | $(MYEXTLIB): sdbm/Makefile |
1704 | cd sdbm && $(MAKE) all |
1705 | '; |
1706 | } |
1707 | |
1708 | |
f1387719 |
1709 | =head2 Hintsfile support |
1710 | |
1711 | MakeMaker.pm uses the architecture specific information from |
1712 | Config.pm. In addition it evaluates architecture specific hints files |
1713 | in a C<hints/> directory. The hints files are expected to be named |
1714 | like their counterparts in C<PERL_SRC/hints>, but with an C<.pl> file |
1715 | name extension (eg. C<next_3_2.pl>). They are simply C<eval>ed by |
1716 | MakeMaker within the WriteMakefile() subroutine, and can be used to |
1717 | execute commands as well as to include special variables. The rules |
1718 | which hintsfile is chosen are the same as in Configure. |
1719 | |
1720 | The hintsfile is eval()ed immediately after the arguments given to |
1721 | WriteMakefile are stuffed into a hash reference $self but before this |
1722 | reference becomes blessed. So if you want to do the equivalent to |
1723 | override or create an attribute you would say something like |
1724 | |
1725 | $self->{LIBS} = ['-ldbm -lucb -lc']; |
1726 | |
005c1a0e |
1727 | =head2 Distribution Support |
1728 | |
1729 | For authors of extensions MakeMaker provides several Makefile |
1730 | targets. Most of the support comes from the ExtUtils::Manifest module, |
1731 | where additional documentation can be found. |
1732 | |
1733 | =over 4 |
1734 | |
1735 | =item make distcheck |
8e07c86e |
1736 | |
005c1a0e |
1737 | reports which files are below the build directory but not in the |
1738 | MANIFEST file and vice versa. (See ExtUtils::Manifest::fullcheck() for |
1739 | details) |
1740 | |
4633a7c4 |
1741 | =item make skipcheck |
1742 | |
1743 | reports which files are skipped due to the entries in the |
1744 | C<MANIFEST.SKIP> file (See ExtUtils::Manifest::skipcheck() for |
1745 | details) |
1746 | |
005c1a0e |
1747 | =item make distclean |
8e07c86e |
1748 | |
005c1a0e |
1749 | does a realclean first and then the distcheck. Note that this is not |
1750 | needed to build a new distribution as long as you are sure, that the |
1751 | MANIFEST file is ok. |
1752 | |
1753 | =item make manifest |
8e07c86e |
1754 | |
005c1a0e |
1755 | rewrites the MANIFEST file, adding all remaining files found (See |
1756 | ExtUtils::Manifest::mkmanifest() for details) |
1757 | |
1758 | =item make distdir |
8e07c86e |
1759 | |
005c1a0e |
1760 | Copies all the files that are in the MANIFEST file to a newly created |
1761 | directory with the name C<$(DISTNAME)-$(VERSION)>. If that directory |
1762 | exists, it will be removed first. |
1763 | |
8e07c86e |
1764 | =item make disttest |
1765 | |
1766 | Makes a distdir first, and runs a C<perl Makefile.PL>, a make, and |
4633a7c4 |
1767 | a make test in that directory. |
8e07c86e |
1768 | |
005c1a0e |
1769 | =item make tardist |
8e07c86e |
1770 | |
3b03c0f3 |
1771 | First does a distdir. Then a command $(PREOP) which defaults to a null |
f1387719 |
1772 | command, followed by $(TOUNIX), which defaults to a null command under |
1773 | UNIX, and will convert files in distribution directory to UNIX format |
1774 | otherwise. Next it runs C<tar> on that directory into a tarfile and |
3b03c0f3 |
1775 | deletes the directory. Finishes with a command $(POSTOP) which |
1776 | defaults to a null command. |
005c1a0e |
1777 | |
1778 | =item make dist |
8e07c86e |
1779 | |
005c1a0e |
1780 | Defaults to $(DIST_DEFAULT) which in turn defaults to tardist. |
1781 | |
1782 | =item make uutardist |
8e07c86e |
1783 | |
005c1a0e |
1784 | Runs a tardist first and uuencodes the tarfile. |
1785 | |
1786 | =item make shdist |
8e07c86e |
1787 | |
3b03c0f3 |
1788 | First does a distdir. Then a command $(PREOP) which defaults to a null |
1789 | command. Next it runs C<shar> on that directory into a sharfile and |
1790 | deletes the intermediate directory again. Finishes with a command |
1791 | $(POSTOP) which defaults to a null command. Note: For shdist to work |
1792 | properly a C<shar> program that can handle directories is mandatory. |
1793 | |
1794 | =item make zipdist |
1795 | |
1796 | First does a distdir. Then a command $(PREOP) which defaults to a null |
1797 | command. Runs C<$(ZIP) $(ZIPFLAGS)> on that directory into a |
1798 | zipfile. Then deletes that directory. Finishes with a command |
1799 | $(POSTOP) which defaults to a null command. |
005c1a0e |
1800 | |
1801 | =item make ci |
8e07c86e |
1802 | |
1803 | Does a $(CI) and a $(RCS_LABEL) on all files in the MANIFEST file. |
1804 | |
1805 | =back |
005c1a0e |
1806 | |
1807 | Customization of the dist targets can be done by specifying a hash |
1808 | reference to the dist attribute of the WriteMakefile call. The |
1809 | following parameters are recognized: |
1810 | |
8e07c86e |
1811 | CI ('ci -u') |
005c1a0e |
1812 | COMPRESS ('compress') |

8e07c86e |
1814 | PREOP ('@ :') |
f1387719 |
1815 | TO_UNIX (depends on the system) |
8e07c86e |
1816 | RCS_LABEL ('rcs -q -Nv$(VERSION_SYM):') |
1817 | SHAR ('shar') |
1818 | SUFFIX ('Z') |
1819 | TAR ('tar') |
1820 | TARFLAGS ('cvf') |
3b03c0f3 |
1821 | ZIP ('zip') |
1822 | ZIPFLAGS ('-r') |
