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340 | most probably outdated.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 |
844 | =head1 DESCRIPTION |
845 | |
846 | This utility is designed to write a Makefile for an extension module |
847 | from a Makefile.PL. It is based on the Makefile.SH model provided by |
848 | Andy Dougherty and the perl5-porters. |
849 | |
850 | It splits the task of generating the Makefile into several subroutines |
851 | that can be individually overridden. Each subroutine returns the text |
852 | it wishes to have written to the Makefile. |
853 | |
f1387719 |
854 | MakeMaker is object oriented. Each directory below the current |
855 | directory that contains a Makefile.PL. Is treated as a separate |
856 | object. This makes it possible to write an unlimited number of |
857 | Makefiles with a single invocation of WriteMakefile(). |
8e07c86e |
858 | |
f1387719 |
859 | =head2 How To Write A Makefile.PL |
8e07c86e |
860 | |
f1387719 |
861 | The short answer is: Don't. Run h2xs(1) before you start thinking |
862 | about writing a module. For so called pm-only modules that consist of |
863 | C<*.pm> files only, h2xs has the very useful C<-X> switch. This will |
864 | generate dummy files of all kinds that are useful for the module |
865 | developer. |
8e07c86e |
866 | |
f1387719 |
867 | The medium answer is: |
8e07c86e |
868 | |
f1387719 |
869 | use ExtUtils::MakeMaker; |
870 | WriteMakefile( NAME => "Foo::Bar" ); |
8e07c86e |
871 | |
f1387719 |
872 | The long answer is below. |
005c1a0e |
873 | |
874 | =head2 Default Makefile Behaviour |
875 | |
f1387719 |
876 | The generated Makefile enables the user of the extension to invoke |
005c1a0e |
877 | |
878 | perl Makefile.PL # optionally "perl Makefile.PL verbose" |
879 | make |
8e07c86e |
880 | make test # optionally set TEST_VERBOSE=1 |
881 | make install # See below |
005c1a0e |
882 | |
883 | The Makefile to be produced may be altered by adding arguments of the |
e05e23b1 |
884 | form C<KEY=VALUE>. E.g. |
005c1a0e |
885 | |
e05e23b1 |
886 | perl Makefile.PL PREFIX=/tmp/myperl5 |
005c1a0e |
887 | |
888 | Other interesting targets in the generated Makefile are |
889 | |
890 | make config # to check if the Makefile is up-to-date |
8e07c86e |
891 | make clean # delete local temp files (Makefile gets renamed) |
892 | make realclean # delete derived files (including ./blib) |
e05e23b1 |
893 | make ci # check in all the files in the MANIFEST file |
005c1a0e |
894 | make dist # see below the Distribution Support section |
895 | |
e05e23b1 |
896 | =head2 make test |
897 | |
898 | MakeMaker checks for the existence of a file named "test.pl" in the |
899 | current directory and if it exists it adds commands to the test target |
900 | of the generated Makefile that will execute the script with the proper |
901 | set of perl C<-I> options. |
902 | |
903 | MakeMaker also checks for any files matching glob("t/*.t"). It will |
904 | add commands to the test target of the generated Makefile that execute |
905 | all matching files via the L<Test::Harness> module with the C<-I> |
906 | switches set correctly. |
907 | |
908 | =head2 make install |
005c1a0e |
909 | |
8e07c86e |
910 | make alone puts all relevant files into directories that are named by |
f1387719 |
911 | the macros INST_LIB, INST_ARCHLIB, INST_SCRIPT, INST_MAN1DIR, and |
912 | INST_MAN3DIR. All these default to something below ./blib if you are |
913 | I<not> building below the perl source directory. If you I<are> |
8e07c86e |
914 | building below the perl source, INST_LIB and INST_ARCHLIB default to |
5b195008 |
915 | ../../lib, and INST_SCRIPT is not defined. |
005c1a0e |
916 | |
e05e23b1 |
917 | The I<install> target of the generated Makefile copies the files found |
918 | below each of the INST_* directories to their INSTALL* |
919 | counterparts. Which counterparts are chosen depends on the setting of |
920 | INSTALLDIRS according to the following table: |
005c1a0e |
921 | |
e05e23b1 |
922 | INSTALLDIRS set to |
923 | perl site |
924 | |
e05e23b1 |
925 | INST_ARCHLIB INSTALLARCHLIB INSTALLSITEARCH |
3b03c0f3 |
926 | INST_LIB INSTALLPRIVLIB INSTALLSITELIB |
f1387719 |
927 | INST_BIN INSTALLBIN |
928 | INST_SCRIPT INSTALLSCRIPT |
e05e23b1 |
929 | INST_MAN1DIR INSTALLMAN1DIR |
930 | INST_MAN3DIR INSTALLMAN3DIR |
005c1a0e |
931 | |
8e07c86e |
932 | The INSTALL... macros in turn default to their %Config |
933 | ($Config{installprivlib}, $Config{installarchlib}, etc.) counterparts. |
005c1a0e |
934 | |
3b03c0f3 |
935 | You can check the values of these variables on your system with |
936 | |
937 | perl -MConfig -le 'print join $/, map |
938 | sprintf("%20s: %s", $_, $Config{$_}), |
939 | grep /^install/, keys %Config' |
940 | |
f1387719 |
941 | And to check the sequence in which the library directories are |
942 | searched by perl, run |
005c1a0e |
943 | |
f1387719 |
944 | perl -le 'print join $/, @INC' |
005c1a0e |
945 | |
005c1a0e |
946 | |
8e07c86e |
947 | =head2 PREFIX attribute |
005c1a0e |
948 | |
0d8023a2 |
949 | The PREFIX attribute can be used to set the INSTALL* attributes in one |
950 | go. The quickest way to install a module in a non-standard place |
005c1a0e |
951 | |
8e07c86e |
952 | perl Makefile.PL PREFIX=~ |
005c1a0e |
953 | |
0d8023a2 |
954 | This will replace the string specified by $Config{prefix} in all |
955 | $Config{install*} values. |
005c1a0e |
956 | |
957 | Note, that the tilde expansion is done by MakeMaker, not by perl by |
8e07c86e |
958 | default, nor by make. |
005c1a0e |
959 | |
005c1a0e |
960 | If the user has superuser privileges, and is not working on AFS |
961 | (Andrew File System) or relatives, then the defaults for |
f1387719 |
962 | INSTALLPRIVLIB, INSTALLARCHLIB, INSTALLSCRIPT, etc. will be appropriate, |
005c1a0e |
963 | and this incantation will be the best: |
964 | |
965 | perl Makefile.PL; make; make test |
966 | make install |
967 | |
8e07c86e |
968 | make install per default writes some documentation of what has been |
e05e23b1 |
969 | done into the file C<$(INSTALLARCHLIB)/perllocal.pod>. This feature |
970 | can be bypassed by calling make pure_install. |
8e07c86e |
971 | |
972 | =head2 AFS users |
973 | |
974 | will have to specify the installation directories as these most |
975 | probably have changed since perl itself has been installed. They will |
976 | have to do this by calling |
977 | |
e05e23b1 |
978 | perl Makefile.PL INSTALLSITELIB=/afs/here/today \ |
f1387719 |
979 | INSTALLSCRIPT=/afs/there/now INSTALLMAN3DIR=/afs/for/manpages |
8e07c86e |
980 | make |
981 | |
e05e23b1 |
982 | Be careful to repeat this procedure every time you recompile an |
983 | extension, unless you are sure the AFS installation directories are |
984 | still valid. |
005c1a0e |
985 | |
8e07c86e |
986 | =head2 Static Linking of a new Perl Binary |
005c1a0e |
987 | |
988 | An extension that is built with the above steps is ready to use on |
989 | systems supporting dynamic loading. On systems that do not support |
990 | dynamic loading, any newly created extension has to be linked together |
991 | with the available resources. MakeMaker supports the linking process |
992 | by creating appropriate targets in the Makefile whenever an extension |
993 | is built. You can invoke the corresponding section of the makefile with |
994 | |
995 | make perl |
996 | |
997 | That produces a new perl binary in the current directory with all |
e05e23b1 |
998 | extensions linked in that can be found in INST_ARCHLIB , SITELIBEXP, |
999 | and PERL_ARCHLIB. To do that, MakeMaker writes a new Makefile, on |
1000 | UNIX, this is called Makefile.aperl (may be system dependent). If you |
1001 | want to force the creation of a new perl, it is recommended, that you |
1002 | delete this Makefile.aperl, so the directories are searched-through |
1003 | for linkable libraries again. |
005c1a0e |
1004 | |
1005 | The binary can be installed into the directory where perl normally |
1006 | resides on your machine with |
1007 | |
1008 | make inst_perl |
1009 | |
1010 | To produce a perl binary with a different name than C<perl>, either say |
1011 | |
1012 | perl Makefile.PL MAP_TARGET=myperl |
1013 | make myperl |
1014 | make inst_perl |
1015 | |
1016 | or say |
1017 | |
1018 | perl Makefile.PL |
1019 | make myperl MAP_TARGET=myperl |
1020 | make inst_perl MAP_TARGET=myperl |
1021 | |
1022 | In any case you will be prompted with the correct invocation of the |
1023 | C<inst_perl> target that installs the new binary into INSTALLBIN. |
1024 | |
8e07c86e |
1025 | make inst_perl per default writes some documentation of what has been |
1026 | done into the file C<$(INSTALLARCHLIB)/perllocal.pod>. This |
1027 | can be bypassed by calling make pure_inst_perl. |
005c1a0e |
1028 | |
e05e23b1 |
1029 | Warning: the inst_perl: target will most probably overwrite your |
1030 | existing perl binary. Use with care! |
005c1a0e |
1031 | |
8e07c86e |
1032 | Sometimes you might want to build a statically linked perl although |
1033 | your system supports dynamic loading. In this case you may explicitly |
1034 | set the linktype with the invocation of the Makefile.PL or make: |
1035 | |
1036 | perl Makefile.PL LINKTYPE=static # recommended |
1037 | |
1038 | or |
1039 | |
1040 | make LINKTYPE=static # works on most systems |
1041 | |
005c1a0e |
1042 | =head2 Determination of Perl Library and Installation Locations |
1043 | |
1044 | MakeMaker needs to know, or to guess, where certain things are |
e05e23b1 |
1045 | located. Especially INST_LIB and INST_ARCHLIB (where to put the files |
1046 | during the make(1) run), PERL_LIB and PERL_ARCHLIB (where to read |
1047 | existing modules from), and PERL_INC (header files and C<libperl*.*>). |
005c1a0e |
1048 | |
1049 | Extensions may be built either using the contents of the perl source |
e05e23b1 |
1050 | directory tree or from the installed perl library. The recommended way |
1051 | is to build extensions after you have run 'make install' on perl |
1052 | itself. You can do that in any directory on your hard disk that is not |
1053 | below the perl source tree. The support for extensions below the ext |
1054 | directory of the perl distribution is only good for the standard |
1055 | extensions that come with perl. |
005c1a0e |
1056 | |
1057 | If an extension is being built below the C<ext/> directory of the perl |
e05e23b1 |
1058 | source then MakeMaker will set PERL_SRC automatically (e.g., |
1059 | C<../..>). If PERL_SRC is defined and the extension is recognized as |
1060 | a standard extension, then other variables default to the following: |
005c1a0e |
1061 | |
1062 | PERL_INC = PERL_SRC |
1063 | PERL_LIB = PERL_SRC/lib |
1064 | PERL_ARCHLIB = PERL_SRC/lib |
1065 | INST_LIB = PERL_LIB |
1066 | INST_ARCHLIB = PERL_ARCHLIB |
1067 | |
1068 | If an extension is being built away from the perl source then MakeMaker |
1069 | will leave PERL_SRC undefined and default to using the installed copy |
1070 | of the perl library. The other variables default to the following: |
1071 | |
e05e23b1 |
1072 | PERL_INC = $archlibexp/CORE |
1073 | PERL_LIB = $privlibexp |
1074 | PERL_ARCHLIB = $archlibexp |
1075 | INST_LIB = ./blib/lib |
1076 | INST_ARCHLIB = ./blib/arch |
005c1a0e |
1077 | |
1078 | If perl has not yet been installed then PERL_SRC can be defined on the |
1079 | command line as shown in the previous section. |
1080 | |
005c1a0e |
1081 | |
f1387719 |
1082 | =head2 Which architecture dependent directory? |
005c1a0e |
1083 | |
f1387719 |
1084 | If you don't want to keep the defaults for the INSTALL* macros, |
1085 | MakeMaker helps you to minimize the typing needed: the usual |
1086 | relationship between INSTALLPRIVLIB and INSTALLARCHLIB is determined |
1087 | by Configure at perl compilation time. MakeMaker supports the user who |
1088 | sets INSTALLPRIVLIB. If INSTALLPRIVLIB is set, but INSTALLARCHLIB not, |
1089 | then MakeMaker defaults the latter to be the same subdirectory of |
1090 | INSTALLPRIVLIB as Configure decided for the counterparts in %Config , |
1091 | otherwise it defaults to INSTALLPRIVLIB. The same relationship holds |
1092 | for INSTALLSITELIB and INSTALLSITEARCH. |
005c1a0e |
1093 | |
f1387719 |
1094 | MakeMaker gives you much more freedom than needed to configure |
1095 | internal variables and get different results. It is worth to mention, |
1096 | that make(1) also lets you configure most of the variables that are |
1097 | used in the Makefile. But in the majority of situations this will not |
1098 | be necessary, and should only be done, if the author of a package |
1099 | recommends it (or you know what you're doing). |

1101 | =head2 Using Attributes and Parameters |
005c1a0e |
1102 | |
1103 | The following attributes can be specified as arguments to WriteMakefile() |
1104 | or as NAME=VALUE pairs on the command line: |
1105 | |
8e07c86e |
1106 | =cut |
005c1a0e |
1107 | |
864a5fa8 |
1108 | # The following "=item C" is used by the attrib_help routine |
8e07c86e |
1109 | # likewise the "=back" below. So be careful when changing it! |
1110 | |
1111 | =over 2 |
1112 | |
864a5fa8 |
1113 | =item C |
8e07c86e |
1114 | |
864a5fa8 |
1115 | Ref to array of *.c file names. Initialised from a directory scan |
1116 | and the values portion of the XS attribute hash. This is not |
1117 | currently used by MakeMaker but may be handy in Makefile.PLs. |
8e07c86e |
1118 | |
864a5fa8 |
1119 | =item CONFIG |
8e07c86e |
1120 | |
864a5fa8 |
1121 | Arrayref. E.g. [qw(archname manext)] defines ARCHNAME & MANEXT from |
1122 | config.sh. MakeMaker will add to CONFIG the following values anyway: |
1123 | ar |
1124 | cc |
1125 | cccdlflags |
1126 | ccdlflags |
1127 | dlext |
1128 | dlsrc |
1129 | ld |
1130 | lddlflags |
1131 | ldflags |
1132 | libc |
1133 | lib_ext |
1134 | obj_ext |
1135 | ranlib |
e05e23b1 |
1136 | sitelibexp |
1137 | sitearchexp |
864a5fa8 |
1138 | so |
8e07c86e |
1139 | |
1140 | =item CONFIGURE |
1141 | |
e05e23b1 |
1142 | CODE reference. The subroutine should return a hash reference. The |
1fef88e7 |
1143 | hash may contain further attributes, e.g. {LIBS =E<gt> ...}, that have to |
8e07c86e |
1144 | be determined by some evaluation method. |
1145 | |
864a5fa8 |
1146 | =item DEFINE |
8e07c86e |
1147 | |
864a5fa8 |
1148 | Something like C<"-DHAVE_UNISTD_H"> |
8e07c86e |
1149 | |
864a5fa8 |
1150 | =item DIR |
8e07c86e |
1151 | |
864a5fa8 |
1152 | Ref to array of subdirectories containing Makefile.PLs e.g. [ 'sdbm' |
1153 | ] in ext/SDBM_File |
8e07c86e |
1154 | |
864a5fa8 |
1155 | =item DISTNAME |
8e07c86e |
1156 | |
e05e23b1 |
1157 | Your name for distributing the package (by tar file). This defaults to |
864a5fa8 |
1158 | NAME above. |
8e07c86e |
1159 | |
864a5fa8 |
1160 | =item DL_FUNCS |
8e07c86e |
1161 | |
864a5fa8 |
1162 | Hashref of symbol names for routines to be made available as |
1163 | universal symbols. Each key/value pair consists of the package name |
1164 | and an array of routine names in that package. Used only under AIX |
1165 | (export lists) and VMS (linker options) at present. The routine |
1166 | names supplied will be expanded in the same way as XSUB names are |
1167 | expanded by the XS() macro. Defaults to |
8e07c86e |
1168 | |
864a5fa8 |
1169 | {"$(NAME)" => ["boot_$(NAME)" ] } |
8e07c86e |
1170 | |
864a5fa8 |
1171 | e.g. |
8e07c86e |
1172 | |
864a5fa8 |
1173 | {"RPC" => [qw( boot_rpcb rpcb_gettime getnetconfigent )], |
1174 | "NetconfigPtr" => [ 'DESTROY'] } |

864a5fa8 |
1176 | =item DL_VARS |
8e07c86e |
1177 | |
864a5fa8 |
1178 | Array of symbol names for variables to be made available as |
1179 | universal symbols. Used only under AIX (export lists) and VMS |
1180 | (linker options) at present. Defaults to []. (e.g. [ qw( |
1181 | Foo_version Foo_numstreams Foo_tree ) ]) |
8e07c86e |
1182 | |
f1387719 |
1183 | =item EXCLUDE_EXT |
1184 | |
1185 | Array of extension names to exclude when doing a static build. This |
1186 | is ignored if INCLUDE_EXT is present. Consult INCLUDE_EXT for more |
1187 | details. (e.g. [ qw( Socket POSIX ) ] ) |
1188 | |
1189 | This attribute may be most useful when specified as a string on the |
1190 | commandline: perl Makefile.PL EXCLUDE_EXT='Socket Safe' |
1191 | |
864a5fa8 |
1192 | =item EXE_FILES |
8e07c86e |
1193 | |
864a5fa8 |
1194 | Ref to array of executable files. The files will be copied to the |
f1387719 |
1195 | INST_SCRIPT directory. Make realclean will delete them from there |
864a5fa8 |
1196 | again. |
8e07c86e |
1197 | |
3b03c0f3 |
1198 | =item NO_VC |
1199 | |
1200 | In general any generated Makefile checks for the current version of |
1201 | MakeMaker and the version the Makefile was built under. If NO_VC is |
1202 | set, the version check is neglected. Do not write this into your |
1203 | Makefile.PL, use it interactively instead. |
1204 | |
864a5fa8 |
1205 | =item FIRST_MAKEFILE |
1206 | |
1207 | The name of the Makefile to be produced. Defaults to the contents of |
1208 | MAKEFILE, but can be overridden. This is used for the second Makefile |
1209 | that will be produced for the MAP_TARGET. |
1210 | |
1211 | =item FULLPERL |
8e07c86e |

1217 | Ref to array of *.h file names. Similar to C. |
1218 | |
1219 | =item INC |
1220 | |
1221 | Include file dirs eg: C<"-I/usr/5include -I/path/to/inc"> |
1222 | |
f1387719 |
1223 | =item INCLUDE_EXT |
1224 | |
1225 | Array of extension names to be included when doing a static build. |
1226 | MakeMaker will normally build with all of the installed extensions when |
1227 | doing a static build, and that is usually the desired behavior. If |
1228 | INCLUDE_EXT is present then MakeMaker will build only with those extensions |
1229 | which are explicitly mentioned. (e.g. [ qw( Socket POSIX ) ]) |
1230 | |
1231 | It is not necessary to mention DynaLoader or the current extension when |
1232 | filling in INCLUDE_EXT. If the INCLUDE_EXT is mentioned but is empty then |
1233 | only DynaLoader and the current extension will be included in the build. |
1234 | |
1235 | This attribute may be most useful when specified as a string on the |
1236 | commandline: perl Makefile.PL INCLUDE_EXT='POSIX Socket Devel::Peek' |
1237 | |
864a5fa8 |
1238 | =item INSTALLARCHLIB |
1239 | |
e05e23b1 |

1246 | |
1247 | =item INSTALLDIRS |
1248 | |
1249 | Determines which of the two sets of installation directories to |
1250 | choose: installprivlib and installarchlib versus installsitelib and |
1251 | installsitearch. The first pair is chosen with INSTALLDIRS=perl, the |
1252 | second with INSTALLDIRS=site. Default is site. |
8e07c86e |
1253 | |
1254 | =item INSTALLMAN1DIR |

1268 | |
f1387719 |
1269 | =item INSTALLSCRIPT |
1270 | |
1271 | Used by 'make install' which copies files from INST_SCRIPT to this |
1272 | directory. |
1273 | |
e05e23b1 |
1274 | =item INSTALLSITELIB |
1275 | |
1276 | Used by 'make install', which copies files from INST_LIB to this |
1277 | directory if INSTALLDIRS is set to site (default). |
1278 | |
1279 | =item INSTALLSITEARCH |
1280 | |
1281 | Used by 'make install', which copies files from INST_ARCHLIB to this |
1282 | directory if INSTALLDIRS is set to site (default). |

1298 | =item INST_LIB |
8e07c86e |
1299 | |
864a5fa8 |

8e07c86e |
1308 | |
864a5fa8 |
1309 | Directory to hold the man pages at 'make' time |
8e07c86e |
1310 | |
f1387719 |
1311 | =item INST_SCRIPT |
1312 | |
1313 | Directory, where executable files should be installed during |
1314 | 'make'. Defaults to "./blib/bin", just to have a dummy location during |
1315 | testing. make install will copy the files in INST_SCRIPT to |
1316 | INSTALLSCRIPT. |
1317 | |
864a5fa8 |
1318 | =item LDFROM |
8e07c86e |
1319 | |
864a5fa8 |
1320 | defaults to "$(OBJECT)" and is used in the ld command to specify |
1321 | what files to link/load from (also see dynamic_lib below for how to |
1322 | specify ld flags) |
8e07c86e |
1323 | |
864a5fa8 |
1324 | =item LIBPERL_A |
8e07c86e |
1325 | |
864a5fa8 |
1326 | The filename of the perllibrary that will be used together with this |
1327 | extension. Defaults to libperl.a. |
8e07c86e |
1328 | |
1329 | =item LIBS |
1330 | |
1331 | An anonymous array of alternative library |
1332 | specifications to be searched for (in order) until |
864a5fa8 |
1333 | at least one library is found. E.g. |
8e07c86e |
1334 | |
1335 | 'LIBS' => ["-lgdbm", "-ldbm -lfoo", "-L/path -ldbm.nfs"] |
1336 | |
1337 | Mind, that any element of the array |
1338 | contains a complete set of arguments for the ld |
1339 | command. So do not specify |
1340 | |
1341 | 'LIBS' => ["-ltcl", "-ltk", "-lX11"] |
1342 | |
1343 | See ODBM_File/Makefile.PL for an example, where an array is needed. If |
1344 | you specify a scalar as in |
1345 | |
1346 | 'LIBS' => "-ltcl -ltk -lX11" |
1347 | |
1348 | MakeMaker will turn it into an array with one element. |
1349 | |
864a5fa8 |
1350 | =item LINKTYPE |
8e07c86e |
1351 | |
e05e23b1 |
1352 | 'static' or 'dynamic' (default unless usedl=undef in |
1353 | config.sh). Should only be used to force static linking (also see |
864a5fa8 |
1354 | linkext below). |
8e07c86e |
1355 | |
864a5fa8 |
1356 | =item MAKEAPERL |
8e07c86e |
1357 | |
864a5fa8 |
1358 | Boolean which tells MakeMaker, that it should include the rules to |
1359 | make a perl. This is handled automatically as a switch by |
1360 | MakeMaker. The user normally does not need it. |
8e07c86e |
1361 | |
864a5fa8 |
1362 | =item MAKEFILE |
8e07c86e |
1363 | |

8e07c86e |
1365 | |
864a5fa8 |
1366 | =item MAN1PODS |
8e07c86e |
1367 | |
864a5fa8 |
1368 | Hashref of pod-containing files. MakeMaker will default this to all |
1369 | EXE_FILES files that include POD directives. The files listed |
1370 | here will be converted to man pages and installed as was requested |
1371 | at Configure time. |
8e07c86e |
1372 | |
864a5fa8 |
1373 | =item MAN3PODS |
8e07c86e |
1374 | |
864a5fa8 |
1375 | Hashref of .pm and .pod files. MakeMaker will default this to all |
1376 | .pod and any .pm files that include POD directives. The files listed |
1377 | here will be converted to man pages and installed as was requested |
1378 | at Configure time. |
8e07c86e |
1379 | |
864a5fa8 |
1380 | =item MAP_TARGET |
8e07c86e |
1381 | |
864a5fa8 |
1382 | If it is intended, that a new perl binary be produced, this variable |
1383 | may hold a name for that binary. Defaults to perl |
8e07c86e |
1384 | |
864a5fa8 |
1385 | =item MYEXTLIB |
4633a7c4 |
1386 | |
864a5fa8 |
1387 | If the extension links to a library that it builds set this to the |
1388 | name of the library (see SDBM_File) |
4633a7c4 |
1389 | |
864a5fa8 |
1390 | =item NAME |
8e07c86e |
1391 | |
864a5fa8 |
1392 | Perl module name for this extension (DBD::Oracle). This will default |
1393 | to the directory name but should be explicitly defined in the |
1394 | Makefile.PL. |
8e07c86e |
1395 | |
864a5fa8 |
1396 | =item NEEDS_LINKING |
8e07c86e |
1397 | |
864a5fa8 |
1398 | MakeMaker will figure out, if an extension contains linkable code |
1399 | anywhere down the directory tree, and will set this variable |
1400 | accordingly, but you can speed it up a very little bit, if you define |
1401 | this boolean variable yourself. |
8e07c86e |
1402 | |
e05e23b1 |
1403 | =item NOECHO |
1404 | |
f1387719 |
1405 | Defaults to C<@>. By setting it to an empty string you can generate a |
e05e23b1 |
1406 | Makefile that echos all commands. Mainly used in debugging MakeMaker |
1407 | itself. |
1408 | |
864a5fa8 |
1409 | =item NORECURS |
8e07c86e |
1410 | |
e05e23b1 |
1411 | Boolean. Attribute to inhibit descending into subdirectories. |
8e07c86e |
1412 | |
864a5fa8 |
1413 | =item OBJECT |
8e07c86e |
1414 | |
864a5fa8 |
1415 | List of object files, defaults to '$(BASEEXT)$(OBJ_EXT)', but can be a long |
1416 | string containing all object files, e.g. "tkpBind.o |
1417 | tkpButton.o tkpCanvas.o" |
8e07c86e |
1418 | |
3b03c0f3 |
1419 | =item OPTIMIZE |
1420 | |
1421 | Defaults to C<-O>. Set it to C<-g> to turn debugging on. The flag is |
1422 | passed to subdirectory makes. |
1423 | |
864a5fa8 |
1424 | =item PERL |
8e07c86e |
1425 | |
864a5fa8 |
1426 | Perl binary for tasks that can be done by miniperl |
8e07c86e |
1427 | |
864a5fa8 |
1428 | =item PERLMAINCC |
005c1a0e |
1429 | |
864a5fa8 |
1430 | The call to the program that is able to compile perlmain.c. Defaults |
1431 | to $(CC). |
005c1a0e |
1432 | |
864a5fa8 |
1433 | =item PERL_ARCHLIB |
005c1a0e |
1434 | |
864a5fa8 |
1435 | Same as above for architecture dependent files |
8e07c86e |
1436 | |
864a5fa8 |
1437 | =item PERL_LIB |
8e07c86e |
1438 | |
864a5fa8 |
1439 | Directory containing the Perl library to use. |
8e07c86e |
1440 | |
864a5fa8 |
1441 | =item PERL_SRC |
8e07c86e |
1442 | |
864a5fa8 |
1443 | Directory containing the Perl source code (use of this should be |
1444 | avoided, it may be undefined) |
8e07c86e |
1445 | |
864a5fa8 |
1446 | =item PL_FILES |
8e07c86e |
1447 | |
864a5fa8 |
1448 | Ref to hash of files to be processed as perl programs. MakeMaker |
1449 | will default to any found *.PL file (except Makefile.PL) being keys |
1450 | and the basename of the file being the value. E.g. |
8e07c86e |
1451 | |
864a5fa8 |
1452 | {'foobar.PL' => 'foobar'} |
8e07c86e |
1453 | |
864a5fa8 |
1454 | The *.PL files are expected to produce output to the target files |
1455 | themselves. |
8e07c86e |
1456 | |
864a5fa8 |
1457 | =item PM |
8e07c86e |
1458 | |
864a5fa8 |
1459 | Hashref of .pm files and *.pl files to be installed. e.g. |
8e07c86e |
1460 | |
864a5fa8 |
1461 | {'name_of_file.pm' => '$(INST_LIBDIR)/install_as.pm'} |
8e07c86e |
1462 | |
864a5fa8 |
1463 | By default this will include *.pm and *.pl. If a lib directory |
1464 | exists and is not listed in DIR (above) then any *.pm and *.pl files |
1465 | it contains will also be included by default. Defining PM in the |
1466 | Makefile.PL will override PMLIBDIRS. |
8e07c86e |
1467 | |
864a5fa8 |
1468 | =item PMLIBDIRS |
8e07c86e |
1469 | |
864a5fa8 |
1470 | Ref to array of subdirectories containing library files. Defaults to |
1471 | [ 'lib', $(BASEEXT) ]. The directories will be scanned and any files |
1472 | they contain will be installed in the corresponding location in the |
1473 | library. A libscan() method can be used to alter the behaviour. |
1474 | Defining PM in the Makefile.PL will override PMLIBDIRS. |
8e07c86e |
1475 | |
864a5fa8 |
1476 | =item PREFIX |
8e07c86e |
1477 | |
864a5fa8 |
1478 | Can be used to set the three INSTALL* attributes in one go (except for |
e05e23b1 |
1479 | probably INSTALLMAN1DIR, if it is not below PREFIX according to |
1480 | %Config). They will have PREFIX as a common directory node and will |
1481 | branch from that node into lib/, lib/ARCHNAME or whatever Configure |
1482 | decided at the build time of your perl (unless you override one of |
1483 | them, of course). |
8e07c86e |
1484 | |
f1387719 |
1485 | =item PREREQ_PM |
8e07c86e |
1486 | |
f1387719 |
1487 | Hashref: Names of modules that need to be available to run this |
1488 | extension (e.g. Fcntl for SDBM_File) are the keys of the hash and the |
1489 | desired version is the value. If the required version number is 0, we |
1490 | only check if any version is installed already. |
8e07c86e |
1491 | |
864a5fa8 |
1492 | =item SKIP |
8e07c86e |
1493 | |
864a5fa8 |
1494 | Arryref. E.g. [qw(name1 name2)] skip (do not write) sections of the |
f1387719 |
1495 | Makefile. Caution! Do not use the SKIP attribute for the neglectible |
1496 | speedup. It may seriously damage the resulting Makefile. Only use it, |
1497 | if you really need it. |
8e07c86e |
1498 | |
864a5fa8 |
1499 | =item TYPEMAPS |
8e07c86e |
1500 | |
864a5fa8 |
1501 | Ref to array of typemap file names. Use this when the typemaps are |
1502 | in some directory other than the current directory or when they are |
1503 | not named B<typemap>. The last typemap in the list takes |
1504 | precedence. A typemap in the current directory has highest |
1505 | precedence, even if it isn't listed in TYPEMAPS. The default system |
1506 | typemap has lowest precedence. |
8e07c86e |
1507 | |
864a5fa8 |
1508 | =item VERSION |
8e07c86e |
1509 | |
864a5fa8 |
1510 | Your version number for distributing the package. This defaults to |
1511 | 0.1. |
8e07c86e |
1512 | |
0d8023a2 |
1513 | =item VERSION_FROM |
1514 | |
1515 | Instead of specifying the VERSION in the Makefile.PL you can let |
1516 | MakeMaker parse a file to determine the version number. The parsing |
1517 | routine requires that the file named by VERSION_FROM contains one |
1518 | single line to compute the version number. The first line in the file |
1519 | that contains the regular expression |
1520 | |
5b195008 |
1521 | /\$(([\w\:\']*)\bVERSION)\b.*\=/ |
0d8023a2 |
1522 | |
1523 | will be evaluated with eval() and the value of the named variable |
1524 | B<after> the eval() will be assigned to the VERSION attribute of the |
1525 | MakeMaker object. The following lines will be parsed o.k.: |
1526 | |
1527 | $VERSION = '1.00'; |
5b195008 |
1528 | ( $VERSION ) = '$Revision: 1.207 $ ' =~ /\$Revision:\s+([^\s]+)/; |
0d8023a2 |
1529 | $FOO::VERSION = '1.10'; |
1530 | |
1531 | but these will fail: |
1532 | |
1533 | my $VERSION = '1.01'; |
1534 | local $VERSION = '1.02'; |
1535 | local $FOO::VERSION = '1.30'; |
1536 | |
1537 | The file named in VERSION_FROM is added as a dependency to Makefile to |
1538 | guarantee, that the Makefile contains the correct VERSION macro after |
1539 | a change of the file. |
1540 | |
864a5fa8 |
1541 | =item XS |
8e07c86e |
1542 | |
864a5fa8 |
1543 | Hashref of .xs files. MakeMaker will default this. e.g. |
8e07c86e |
1544 | |
864a5fa8 |
1545 | {'name_of_file.xs' => 'name_of_file.c'} |
8e07c86e |
1546 | |
864a5fa8 |
1547 | The .c files will automatically be included in the list of files |
1548 | deleted by a make clean. |
4633a7c4 |
1549 | |
864a5fa8 |
1550 | =item XSOPT |
8e07c86e |
1551 | |
864a5fa8 |
1552 | String of options to pass to xsubpp. This might include C<-C++> or |
1553 | C<-extern>. Do not include typemaps here; the TYPEMAP parameter exists for |
1554 | that purpose. |
8e07c86e |
1555 | |
864a5fa8 |
1556 | =item XSPROTOARG |
4633a7c4 |
1557 | |
4e68a208 |
1558 | May be set to an empty string, which is identical to C<-prototypes>, or |
864a5fa8 |
1559 | C<-noprototypes>. See the xsubpp documentation for details. MakeMaker |
4e68a208 |
1560 | defaults to the empty string. |

1590 | If you specify COMPRESS, then SUFFIX should also be altered, as it is |
1591 | needed to tell make the target file of the compression. Setting |
1592 | DIST_CP to ln can be useful, if you need to preserve the timestamps on |
1593 | your files. DIST_CP can take the values 'cp', which copies the file, |
1594 | 'ln', which links the file, and 'best' which copies symbolic links and |
1595 | links the rest. Default is 'best'. |

1637 | =head2 Overriding MakeMaker Methods |
1638 | |
1639 | If you cannot achieve the desired Makefile behaviour by specifying |
1640 | attributes you may define private subroutines in the Makefile.PL. |
1641 | Each subroutines returns the text it wishes to have written to |
1642 | the Makefile. To override a section of the Makefile you can |
1643 | either say: |
1644 | |
1645 | sub MY::c_o { "new literal text" } |
1646 | |
1647 | or you can edit the default by saying something like: |
1648 | |
8e07c86e |
1649 | sub MY::c_o { |
f1387719 |
1650 | my($inherited) = shift->SUPER::c_o(@_); |
1651 | $inherited =~ s/old text/new text/; |
1652 | $inherited; |
8e07c86e |
1653 | } |
1654 | |
f1387719 |
1655 | If you running experiments with embedding perl as a library into other |
1656 | applications, you might find MakeMaker not sufficient. You'd better |
1657 | have a look at ExtUtils::embed which is a collection of utilities for |
1658 | embedding. |
005c1a0e |
1659 | |
1660 | If you still need a different solution, try to develop another |
1661 | subroutine, that fits your needs and submit the diffs to |
8e07c86e |
1662 | F<perl5-porters@nicoh.com> or F<comp.lang.perl.misc> as appropriate. |
005c1a0e |
1663 | |
3b03c0f3 |
1664 | For a complete description of all MakeMaker methods see L<ExtUtils::MM_Unix>. |
1665 | |
1666 | Here is a simple example of how to add a new target to the generated |
1667 | Makefile: |
1668 | |
1669 | sub MY::postamble { |
1670 | ' |
1671 | $(MYEXTLIB): sdbm/Makefile |
1672 | cd sdbm && $(MAKE) all |
1673 | '; |
1674 | } |
1675 | |
1676 | |
f1387719 |
1677 | =head2 Hintsfile support |
1678 | |
1679 | MakeMaker.pm uses the architecture specific information from |
1680 | Config.pm. In addition it evaluates architecture specific hints files |
1681 | in a C<hints/> directory. The hints files are expected to be named |
1682 | like their counterparts in C<PERL_SRC/hints>, but with an C<.pl> file |
1683 | name extension (eg. C<next_3_2.pl>). They are simply C<eval>ed by |
1684 | MakeMaker within the WriteMakefile() subroutine, and can be used to |
1685 | execute commands as well as to include special variables. The rules |
1686 | which hintsfile is chosen are the same as in Configure. |
1687 | |
1688 | The hintsfile is eval()ed immediately after the arguments given to |
1689 | WriteMakefile are stuffed into a hash reference $self but before this |
1690 | reference becomes blessed. So if you want to do the equivalent to |
1691 | override or create an attribute you would say something like |
1692 | |
1693 | $self->{LIBS} = ['-ldbm -lucb -lc']; |
1694 | |
005c1a0e |
1695 | =head2 Distribution Support |
1696 | |
1697 | For authors of extensions MakeMaker provides several Makefile |
1698 | targets. Most of the support comes from the ExtUtils::Manifest module, |
1699 | where additional documentation can be found. |

8e07c86e |
1704 | |
005c1a0e |
1705 | reports which files are below the build directory but not in the |
1706 | MANIFEST file and vice versa. (See ExtUtils::Manifest::fullcheck() for |
1707 | details) |
1708 | |

1709 | =item make skipcheck |
1710 | |
1711 | reports which files are skipped due to the entries in the |
1712 | C<MANIFEST.SKIP> file (See ExtUtils::Manifest::skipcheck() for |
1713 | details) |
1714 | |
005c1a0e |
1715 | =item make distclean |
8e07c86e |
1716 | |
005c1a0e |
1717 | does a realclean first and then the distcheck. Note that this is not |
1718 | needed to build a new distribution as long as you are sure, that the |
1719 | MANIFEST file is ok. |
1720 | |
1721 | =item make manifest |
8e07c86e |

1725 | |
1726 | =item make distdir |
8e07c86e |
1727 | |
005c1a0e |
1728 | Copies all the files that are in the MANIFEST file to a newly created |
1729 | directory with the name C<$(DISTNAME)-$(VERSION)>. If that directory |
1730 | exists, it will be removed first. |
1731 | |
8e07c86e |
1732 | =item make disttest |
1733 | |
1734 | Makes a distdir first, and runs a C<perl Makefile.PL>, a make, and |

1737 | =item make tardist |
8e07c86e |
1738 | |

1739 | First does a distdir. Then a command $(PREOP) which defaults to a null |
f1387719 |
1740 | command, followed by $(TOUNIX), which defaults to a null command under |
1741 | UNIX, and will convert files in distribution directory to UNIX format |
1742 | otherwise. Next it runs C<tar> on that directory into a tarfile and |
3b03c0f3 |
1743 | deletes the directory. Finishes with a command $(POSTOP) which |
1744 | defaults to a null command. |
005c1a0e |
1745 | |
1746 | =item make dist |
8e07c86e |
1747 | |
005c1a0e |

1753 | |
1754 | =item make shdist |
8e07c86e |
1755 | |
3b03c0f3 |
1756 | First does a distdir. Then a command $(PREOP) which defaults to a null |
1757 | command. Next it runs C<shar> on that directory into a sharfile and |
1758 | deletes the intermediate directory again. Finishes with a command |
1759 | $(POSTOP) which defaults to a null command. Note: For shdist to work |
1760 | properly a C<shar> program that can handle directories is mandatory. |
1761 | |
1762 | =item make zipdist |
1763 | |
1764 | First does a distdir. Then a command $(PREOP) which defaults to a null |
1765 | command. Runs C<$(ZIP) $(ZIPFLAGS)> on that directory into a |
1766 | zipfile. Then deletes that directory. Finishes with a command |
1767 | $(POSTOP) which defaults to a null command. |
005c1a0e |
1768 | |
1769 | =item make ci |
8e07c86e |
1770 | |
1771 | Does a $(CI) and a $(RCS_LABEL) on all files in the MANIFEST file. |
1772 | |
1773 | =back |
005c1a0e |
