347 | The extension you are trying to build apparently is rather old and |
348 | most probably outdated. We detect that from the fact, that a | |
349 | subroutine "writeMakefile" is called, and this subroutine is not | |
350 | supported anymore since about October 1994. | |
40000a8c | 351 | |
4633a7c4 LW |
352 | Please contact the author or look into CPAN (details about CPAN can be |
353 | found in the FAQ and at http:/www.perl.com) for a more recent version | |
354 | of the extension. If you're really desperate, you can try to change | |
355 | the subroutine name from writeMakefile to WriteMakefile and rerun | |
356 | 'perl Makefile.PL', but you're most probably left alone, when you do | |
357 | so. | |

005c1a0e AD |
877 | =head1 DESCRIPTION |
878 | ||
879 | This utility is designed to write a Makefile for an extension module | |
880 | from a Makefile.PL. It is based on the Makefile.SH model provided by | |
881 | Andy Dougherty and the perl5-porters. | |
882 | ||
883 | It splits the task of generating the Makefile into several subroutines | |
884 | that can be individually overridden. Each subroutine returns the text | |
885 | it wishes to have written to the Makefile. | |
886 | ||
f1387719 | 887 | MakeMaker is object oriented. Each directory below the current |
888 | directory that contains a Makefile.PL. Is treated as a separate | |
889 | object. This makes it possible to write an unlimited number of | |
890 | Makefiles with a single invocation of WriteMakefile(). | |
8e07c86e | 891 | |
f1387719 | 892 | =head2 How To Write A Makefile.PL |
8e07c86e | 893 | |
bab2b58e A |
894 | The short answer is: Don't. |
895 | ||
896 | Always begin with h2xs. | |
897 | Always begin with h2xs! | |
898 | ALWAYS BEGIN WITH H2XS! | |
899 | ||
900 | even if you're not building around a header file, and even if you | |
901 | don't have an XS component. | |
902 | ||
903 | Run h2xs(1) before you start thinking about writing a module. For so | |
904 | called pm-only modules that consist of C<*.pm> files only, h2xs has | |
905 | the C<-X> switch. This will generate dummy files of all kinds that are | |
906 | useful for the module developer. | |
8e07c86e | 907 | |
f1387719 | 908 | The medium answer is: |
8e07c86e | 909 | |
f1387719 | 910 | use ExtUtils::MakeMaker; |
911 | WriteMakefile( NAME => "Foo::Bar" ); | |
8e07c86e | 912 | |
bab2b58e | 913 | The long answer is the rest of the manpage :-) |
005c1a0e AD |
914 | |
915 | =head2 Default Makefile Behaviour | |
916 | ||
f1387719 | 917 | The generated Makefile enables the user of the extension to invoke |
005c1a0e AD |
918 | |
919 | perl Makefile.PL # optionally "perl Makefile.PL verbose" | |
920 | make | |
8e07c86e AD |
921 | make test # optionally set TEST_VERBOSE=1 |
922 | make install # See below | |
005c1a0e AD |
923 | |
924 | The Makefile to be produced may be altered by adding arguments of the | |
e05e23b1 | 925 | form C<KEY=VALUE>. E.g. |
005c1a0e | 926 | |
e05e23b1 | 927 | perl Makefile.PL PREFIX=/tmp/myperl5 |
005c1a0e AD |
928 | |
929 | Other interesting targets in the generated Makefile are | |
930 | ||
931 | make config # to check if the Makefile is up-to-date | |
8e07c86e AD |
932 | make clean # delete local temp files (Makefile gets renamed) |
933 | make realclean # delete derived files (including ./blib) | |
e05e23b1 | 934 | make ci # check in all the files in the MANIFEST file |
005c1a0e AD |
935 | make dist # see below the Distribution Support section |
936 | ||
e05e23b1 | 937 | =head2 make test |
938 | ||
bab2b58e | 939 | MakeMaker checks for the existence of a file named F<test.pl> in the |
e05e23b1 | 940 | current directory and if it exists it adds commands to the test target |
941 | of the generated Makefile that will execute the script with the proper | |
942 | set of perl C<-I> options. | |
943 | ||
944 | MakeMaker also checks for any files matching glob("t/*.t"). It will | |
945 | add commands to the test target of the generated Makefile that execute | |
946 | all matching files via the L<Test::Harness> module with the C<-I> | |
947 | switches set correctly. | |
948 | ||
bab2b58e A |
949 | =head2 make testdb |
950 | ||
951 | A useful variation of the above is the target C<testdb>. It runs the | |
952 | test under the Perl debugger (see L<perldebug>). If the file | |
953 | F<test.pl> exists in the current directory, it is used for the test. | |
954 | ||
955 | If you want to debug some other testfile, set C<TEST_FILE> variable | |
956 | thusly: | |
957 | ||
958 | make testdb TEST_FILE=t/mytest.t | |
959 | ||
960 | By default the debugger is called using C<-d> option to perl. If you | |
961 | want to specify some other option, set C<TESTDB_SW> variable: | |
962 | ||
963 | make testdb TESTDB_SW=-Dx | |
964 | ||
e05e23b1 | 965 | =head2 make install |
005c1a0e | 966 | |
8e07c86e | 967 | make alone puts all relevant files into directories that are named by |
f1387719 | 968 | the macros INST_LIB, INST_ARCHLIB, INST_SCRIPT, INST_MAN1DIR, and |
969 | INST_MAN3DIR. All these default to something below ./blib if you are | |
970 | I<not> building below the perl source directory. If you I<are> | |
8e07c86e | 971 | building below the perl source, INST_LIB and INST_ARCHLIB default to |
5b195008 | 972 | ../../lib, and INST_SCRIPT is not defined. |
005c1a0e | 973 | |
e05e23b1 | 974 | The I<install> target of the generated Makefile copies the files found |
975 | below each of the INST_* directories to their INSTALL* | |
976 | counterparts. Which counterparts are chosen depends on the setting of | |
977 | INSTALLDIRS according to the following table: | |
005c1a0e | 978 | |
e05e23b1 | 979 | INSTALLDIRS set to |
980 | perl site | |
981 | ||
e05e23b1 | 982 | INST_ARCHLIB INSTALLARCHLIB INSTALLSITEARCH |
3b03c0f3 | 983 | INST_LIB INSTALLPRIVLIB INSTALLSITELIB |
f1387719 | 984 | INST_BIN INSTALLBIN |
985 | INST_SCRIPT INSTALLSCRIPT | |
e05e23b1 | 986 | INST_MAN1DIR INSTALLMAN1DIR |
987 | INST_MAN3DIR INSTALLMAN3DIR | |
005c1a0e | 988 | |
8e07c86e AD |
989 | The INSTALL... macros in turn default to their %Config |
990 | ($Config{installprivlib}, $Config{installarchlib}, etc.) counterparts. | |
005c1a0e | 991 | |
3b03c0f3 | 992 | You can check the values of these variables on your system with |
993 | ||
bab2b58e | 994 | perl '-V:install.*' |
3b03c0f3 | 995 | |
f1387719 | 996 | And to check the sequence in which the library directories are |
997 | searched by perl, run | |
005c1a0e | 998 | |
f1387719 | 999 | perl -le 'print join $/, @INC' |
005c1a0e | 1000 | |
005c1a0e | 1001 | |
bab2b58e A |
1002 | =head2 PREFIX and LIB attribute |
1003 | ||
1004 | PREFIX and LIB can be used to set several INSTALL* attributes in one | |
1005 | go. The quickest way to install a module in a non-standard place might | |
1006 | be | |
1007 | ||
1008 | perl Makefile.PL LIB=~/lib | |
005c1a0e | 1009 | |
bab2b58e A |
1010 | This will install the module's architecture-independent files into |
1011 | ~/lib, the architecture-dependent files into ~/lib/$archname/auto. | |
1012 | ||
1013 | Another way to specify many INSTALL directories with a single | |
1014 | parameter is PREFIX. | |
005c1a0e | 1015 | |
8e07c86e | 1016 | perl Makefile.PL PREFIX=~ |
005c1a0e | 1017 | |
0d8023a2 | 1018 | This will replace the string specified by $Config{prefix} in all |
1019 | $Config{install*} values. | |
005c1a0e | 1020 | |
bab2b58e A |
1021 | Note, that in both cases the tilde expansion is done by MakeMaker, not |
1022 | by perl by default, nor by make. Conflicts between parmeters LIB, | |
1023 | PREFIX and the various INSTALL* arguments are resolved so that | |
1024 | XXX | |
005c1a0e | 1025 | |
005c1a0e AD |
1026 | If the user has superuser privileges, and is not working on AFS |
1027 | (Andrew File System) or relatives, then the defaults for | |
f1387719 | 1028 | INSTALLPRIVLIB, INSTALLARCHLIB, INSTALLSCRIPT, etc. will be appropriate, |
005c1a0e AD |
1029 | and this incantation will be the best: |
1030 | ||
1031 | perl Makefile.PL; make; make test | |
1032 | make install | |
1033 | ||
8e07c86e | 1034 | make install per default writes some documentation of what has been |
e05e23b1 | 1035 | done into the file C<$(INSTALLARCHLIB)/perllocal.pod>. This feature |
1036 | can be bypassed by calling make pure_install. | |
8e07c86e AD |
1037 | |
1038 | =head2 AFS users | |
1039 | ||
1040 | will have to specify the installation directories as these most | |
1041 | probably have changed since perl itself has been installed. They will | |
1042 | have to do this by calling | |
1043 | ||
e05e23b1 | 1044 | perl Makefile.PL INSTALLSITELIB=/afs/here/today \ |
f1387719 | 1045 | INSTALLSCRIPT=/afs/there/now INSTALLMAN3DIR=/afs/for/manpages |
8e07c86e AD |
1046 | make |
1047 | ||
e05e23b1 | 1048 | Be careful to repeat this procedure every time you recompile an |
1049 | extension, unless you are sure the AFS installation directories are | |
1050 | still valid. | |
005c1a0e | 1051 | |
8e07c86e | 1052 | =head2 Static Linking of a new Perl Binary |
005c1a0e AD |
1053 | |
1054 | An extension that is built with the above steps is ready to use on | |
1055 | systems supporting dynamic loading. On systems that do not support | |
1056 | dynamic loading, any newly created extension has to be linked together | |
1057 | with the available resources. MakeMaker supports the linking process | |
1058 | by creating appropriate targets in the Makefile whenever an extension | |
1059 | is built. You can invoke the corresponding section of the makefile with | |
1060 | ||
1061 | make perl | |
1062 | ||
1063 | That produces a new perl binary in the current directory with all | |
e05e23b1 | 1064 | extensions linked in that can be found in INST_ARCHLIB , SITELIBEXP, |
1065 | and PERL_ARCHLIB. To do that, MakeMaker writes a new Makefile, on | |
1066 | UNIX, this is called Makefile.aperl (may be system dependent). If you | |
1067 | want to force the creation of a new perl, it is recommended, that you | |
1068 | delete this Makefile.aperl, so the directories are searched-through | |
1069 | for linkable libraries again. | |
005c1a0e AD |
1070 | |
1071 | The binary can be installed into the directory where perl normally | |
1072 | resides on your machine with | |
1073 | ||
1074 | make inst_perl | |
1075 | ||
1076 | To produce a perl binary with a different name than C<perl>, either say | |
1077 | ||
1078 | perl Makefile.PL MAP_TARGET=myperl | |
1079 | make myperl | |
1080 | make inst_perl | |
1081 | ||
1082 | or say | |
1083 | ||
1084 | perl Makefile.PL | |
1085 | make myperl MAP_TARGET=myperl | |
1086 | make inst_perl MAP_TARGET=myperl | |
1087 | ||
1088 | In any case you will be prompted with the correct invocation of the | |
1089 | C<inst_perl> target that installs the new binary into INSTALLBIN. | |
1090 | ||
8e07c86e AD |
1091 | make inst_perl per default writes some documentation of what has been |
1092 | done into the file C<$(INSTALLARCHLIB)/perllocal.pod>. This | |
1093 | can be bypassed by calling make pure_inst_perl. | |
005c1a0e | 1094 | |
e05e23b1 | 1095 | Warning: the inst_perl: target will most probably overwrite your |
1096 | existing perl binary. Use with care! | |
005c1a0e | 1097 | |
8e07c86e AD |
1098 | Sometimes you might want to build a statically linked perl although |
1099 | your system supports dynamic loading. In this case you may explicitly | |
1100 | set the linktype with the invocation of the Makefile.PL or make: | |
1101 | ||
1102 | perl Makefile.PL LINKTYPE=static # recommended | |
1103 | ||
1104 | or | |
1105 | ||
1106 | make LINKTYPE=static # works on most systems | |
1107 | ||
005c1a0e AD |
1108 | =head2 Determination of Perl Library and Installation Locations |
1109 | ||
1110 | MakeMaker needs to know, or to guess, where certain things are | |
e05e23b1 | 1111 | located. Especially INST_LIB and INST_ARCHLIB (where to put the files |
1112 | during the make(1) run), PERL_LIB and PERL_ARCHLIB (where to read | |
1113 | existing modules from), and PERL_INC (header files and C<libperl*.*>). | |
005c1a0e AD |
1114 | |
1115 | Extensions may be built either using the contents of the perl source | |
e05e23b1 | 1116 | directory tree or from the installed perl library. The recommended way |
1117 | is to build extensions after you have run 'make install' on perl | |
1118 | itself. You can do that in any directory on your hard disk that is not | |
1119 | below the perl source tree. The support for extensions below the ext | |
1120 | directory of the perl distribution is only good for the standard | |
1121 | extensions that come with perl. | |
005c1a0e AD |
1122 | |
1123 | If an extension is being built below the C<ext/> directory of the perl | |
e05e23b1 | 1124 | source then MakeMaker will set PERL_SRC automatically (e.g., |
1125 | C<../..>). If PERL_SRC is defined and the extension is recognized as | |
1126 | a standard extension, then other variables default to the following: | |
005c1a0e AD |
1127 | |
1128 | PERL_INC = PERL_SRC | |
1129 | PERL_LIB = PERL_SRC/lib | |
1130 | PERL_ARCHLIB = PERL_SRC/lib | |
1131 | INST_LIB = PERL_LIB | |
1132 | INST_ARCHLIB = PERL_ARCHLIB | |
1133 | ||
1134 | If an extension is being built away from the perl source then MakeMaker | |
1135 | will leave PERL_SRC undefined and default to using the installed copy | |
1136 | of the perl library. The other variables default to the following: | |
1137 | ||
e05e23b1 | 1138 | PERL_INC = $archlibexp/CORE |
1139 | PERL_LIB = $privlibexp | |
1140 | PERL_ARCHLIB = $archlibexp | |
1141 | INST_LIB = ./blib/lib | |
1142 | INST_ARCHLIB = ./blib/arch | |
005c1a0e AD |
1143 | |
1144 | If perl has not yet been installed then PERL_SRC can be defined on the | |
1145 | command line as shown in the previous section. | |
1146 | ||
005c1a0e | 1147 | |
f1387719 | 1148 | =head2 Which architecture dependent directory? |
005c1a0e | 1149 | |
f1387719 | 1150 | If you don't want to keep the defaults for the INSTALL* macros, |
1151 | MakeMaker helps you to minimize the typing needed: the usual | |
1152 | relationship between INSTALLPRIVLIB and INSTALLARCHLIB is determined | |
1153 | by Configure at perl compilation time. MakeMaker supports the user who | |
1154 | sets INSTALLPRIVLIB. If INSTALLPRIVLIB is set, but INSTALLARCHLIB not, | |
1155 | then MakeMaker defaults the latter to be the same subdirectory of | |
1156 | INSTALLPRIVLIB as Configure decided for the counterparts in %Config , | |
1157 | otherwise it defaults to INSTALLPRIVLIB. The same relationship holds | |
1158 | for INSTALLSITELIB and INSTALLSITEARCH. | |
005c1a0e | 1159 | |
f1387719 | 1160 | MakeMaker gives you much more freedom than needed to configure |
1161 | internal variables and get different results. It is worth to mention, | |
1162 | that make(1) also lets you configure most of the variables that are | |
1163 | used in the Makefile. But in the majority of situations this will not | |
1164 | be necessary, and should only be done, if the author of a package | |
1165 | recommends it (or you know what you're doing). | |
005c1a0e | 1166 | |
e05e23b1 | 1167 | =head2 Using Attributes and Parameters |
005c1a0e AD |
1168 | |
1169 | The following attributes can be specified as arguments to WriteMakefile() | |
1170 | or as NAME=VALUE pairs on the command line: | |
1171 | ||
8e07c86e | 1172 | =cut |
005c1a0e | 1173 | |
864a5fa8 | 1174 | # The following "=item C" is used by the attrib_help routine |
8e07c86e AD |
1175 | # likewise the "=back" below. So be careful when changing it! |
1176 | ||
1177 | =over 2 | |
1178 | ||
864a5fa8 | 1179 | =item C |
8e07c86e | 1180 | |
864a5fa8 AD |
1181 | Ref to array of *.c file names. Initialised from a directory scan |
1182 | and the values portion of the XS attribute hash. This is not | |
1183 | currently used by MakeMaker but may be handy in Makefile.PLs. | |
8e07c86e | 1184 | |
84902520 TB |
1185 | =item CCFLAGS |
1186 | ||
1187 | String that will be included in the compiler call command line between | |
1188 | the arguments INC and OPTIMIZE. | |
1189 | ||
864a5fa8 | 1190 | =item CONFIG |
8e07c86e | 1191 | |
864a5fa8 AD |

1299 | ||
1300 | Array of extension names to be included when doing a static build. | |
1301 | MakeMaker will normally build with all of the installed extensions when | |
1302 | doing a static build, and that is usually the desired behavior. If | |
1303 | INCLUDE_EXT is present then MakeMaker will build only with those extensions | |
1304 | which are explicitly mentioned. (e.g. [ qw( Socket POSIX ) ]) | |
1305 | ||
1306 | It is not necessary to mention DynaLoader or the current extension when | |
1307 | filling in INCLUDE_EXT. If the INCLUDE_EXT is mentioned but is empty then | |
1308 | only DynaLoader and the current extension will be included in the build. | |

1414 | |
1415 | 'LIBS' => ["-lgdbm", "-ldbm -lfoo", "-L/path -ldbm.nfs"] | |
1416 | ||
1417 | Mind, that any element of the array | |
1418 | contains a complete set of arguments for the ld | |
1419 | command. So do not specify | |
1420 | ||
1421 | 'LIBS' => ["-ltcl", "-ltk", "-lX11"] | |
1422 | ||
1423 | See ODBM_File/Makefile.PL for an example, where an array is needed. If | |
1424 | you specify a scalar as in | |

864a5fa8 | 1476 | =item NEEDS_LINKING |
8e07c86e | 1477 | |
864a5fa8 AD |
1478 | MakeMaker will figure out, if an extension contains linkable code |
1479 | anywhere down the directory tree, and will set this variable | |
1480 | accordingly, but you can speed it up a very little bit, if you define | |
1481 | this boolean variable yourself. | |

e05e23b1 | 1483 | =item NOECHO |
1484 | ||
f1387719 | 1485 | Defaults to C<@>. By setting it to an empty string you can generate a |

8e07c86e | 1527 | |
864a5fa8 AD |
1528 | Ref to hash of files to be processed as perl programs. MakeMaker |
1529 | will default to any found *.PL file (except Makefile.PL) being keys | |
1530 | and the basename of the file being the value. E.g. | |
8e07c86e | 1531 | |
864a5fa8 | 1532 | {'foobar.PL' => 'foobar'} |
8e07c86e | 1533 | |

1534 | The *.PL files are expected to produce output to the target files |
1535 | themselves. | |
8e07c86e | 1536 | |
864a5fa8 | 1537 | =item PM |
8e07c86e | 1538 | |
864a5fa8 | 1539 | Hashref of .pm files and *.pl files to be installed. e.g. |

a3cb178b GS |
1543 | By default this will include *.pm and *.pl and the files found in |
1544 | the PMLIBDIRS directories. Defining PM in the | |
864a5fa8 | 1545 | Makefile.PL will override PMLIBDIRS. |

864a5fa8 | 1547 | =item PMLIBDIRS |
8e07c86e | 1548 | |
864a5fa8 | 1549 | Ref to array of subdirectories containing library files. Defaults to |
a3cb178b | 1550 | [ 'lib', $(BASEEXT) ]. The directories will be scanned and I<any> files |
864a5fa8 AD |
1551 | they contain will be installed in the corresponding location in the |
1552 | library. A libscan() method can be used to alter the behaviour. | |
1553 | Defining PM in the Makefile.PL will override PMLIBDIRS. | |
8e07c86e | 1554 | |
864a5fa8 | 1555 | =item PREFIX |
8e07c86e | 1556 | |
864a5fa8 | 1557 | Can be used to set the three INSTALL* attributes in one go (except for |
e05e23b1 | 1558 | probably INSTALLMAN1DIR, if it is not below PREFIX according to |
1559 | %Config). They will have PREFIX as a common directory node and will | |
1560 | branch from that node into lib/, lib/ARCHNAME or whatever Configure | |
1561 | decided at the build time of your perl (unless you override one of | |
1562 | them, of course). | |

f1387719 | 1566 | Hashref: Names of modules that need to be available to run this |
1567 | extension (e.g. Fcntl for SDBM_File) are the keys of the hash and the | |
1568 | desired version is the value. If the required version number is 0, we | |
1569 | only check if any version is installed already. | |
8e07c86e | 1570 | |
864a5fa8 | 1571 | =item SKIP |
8e07c86e | 1572 | |
864a5fa8 | 1573 | Arryref. E.g. [qw(name1 name2)] skip (do not write) sections of the |
f1387719 | 1574 | Makefile. Caution! Do not use the SKIP attribute for the neglectible |
1575 | speedup. It may seriously damage the resulting Makefile. Only use it, | |
1576 | if you really need it. | |

1580 | Ref to array of typemap file names. Use this when the typemaps are |
1581 | in some directory other than the current directory or when they are | |
1582 | not named B<typemap>. The last typemap in the list takes | |
1583 | precedence. A typemap in the current directory has highest | |
1584 | precedence, even if it isn't listed in TYPEMAPS. The default system | |
1585 | typemap has lowest precedence. | |

1593 | ||
1594 | Instead of specifying the VERSION in the Makefile.PL you can let | |
1595 | MakeMaker parse a file to determine the version number. The parsing | |
1596 | routine requires that the file named by VERSION_FROM contains one | |
1597 | single line to compute the version number. The first line in the file | |
1598 | that contains the regular expression | |
1599 | ||
84902520 | 1600 | /([\$*])(([\w\:\']*)\bVERSION)\b.*\=/ |
0d8023a2 | 1601 | |
1602 | will be evaluated with eval() and the value of the named variable | |
1603 | B<after> the eval() will be assigned to the VERSION attribute of the | |
1604 | MakeMaker object. The following lines will be parsed o.k.: | |
1605 | ||
1606 | $VERSION = '1.00'; | |
84902520 TB |
1607 | *VERSION = \'1.01'; |
1608 | ( $VERSION ) = '$Revision: 1.216 $ ' =~ /\$Revision:\s+([^\s]+)/; | |
0d8023a2 | 1609 | $FOO::VERSION = '1.10'; |
84902520 | 1610 | *FOO::VERSION = \'1.11'; |
0d8023a2 | 1611 | |
1612 | but these will fail: | |
1613 | ||
1614 | my $VERSION = '1.01'; | |
1615 | local $VERSION = '1.02'; | |
1616 | local $FOO::VERSION = '1.30'; | |
1617 | ||
84902520 TB |
1618 | The file named in VERSION_FROM is not added as a dependency to |
1619 | Makefile. This is not really correct, but it would be a major pain | |
1620 | during development to have to rewrite the Makefile for any smallish | |
1621 | change in that file. If you want to make sure that the Makefile | |
1622 | contains the correct VERSION macro after any change of the file, you | |
1623 | would have to do something like | |
1624 | ||
1625 | depend => { Makefile => '$(VERSION_FROM)' } | |

1681 | your files. DIST_CP can take the values 'cp', which copies the file, | |
1682 | 'ln', which links the file, and 'best' which copies symbolic links and | |

1725 | =head2 Overriding MakeMaker Methods |
1726 | ||
1727 | If you cannot achieve the desired Makefile behaviour by specifying | |
1728 | attributes you may define private subroutines in the Makefile.PL. | |
1729 | Each subroutines returns the text it wishes to have written to | |
1730 | the Makefile. To override a section of the Makefile you can | |
1731 | either say: | |
1732 | ||
1733 | sub MY::c_o { "new literal text" } | |
1734 | ||
1735 | or you can edit the default by saying something like: | |
1736 | ||
8e07c86e | 1737 | sub MY::c_o { |
14870ecd CS |
1738 | package MY; # so that "SUPER" works right |
1739 | my $inherited = shift->SUPER::c_o(@_); | |
f1387719 | 1740 | $inherited =~ s/old text/new text/; |
1741 | $inherited; | |
8e07c86e AD |
1742 | } |
1743 | ||
f1387719 | 1744 | If you running experiments with embedding perl as a library into other |
1745 | applications, you might find MakeMaker not sufficient. You'd better | |
1746 | have a look at ExtUtils::embed which is a collection of utilities for | |
1747 | embedding. | |
005c1a0e AD |
1748 | |
1749 | If you still need a different solution, try to develop another | |
1750 | subroutine, that fits your needs and submit the diffs to | |
8e07c86e | 1751 | F<perl5-porters@nicoh.com> or F<comp.lang.perl.misc> as appropriate. |
005c1a0e | 1752 | |
3b03c0f3 | 1753 | For a complete description of all MakeMaker methods see L<ExtUtils::MM_Unix>. |
1754 | ||
1755 | Here is a simple example of how to add a new target to the generated | |
1756 | Makefile: | |
1757 | ||
1758 | sub MY::postamble { | |
1759 | ' | |
1760 | $(MYEXTLIB): sdbm/Makefile | |
1761 | cd sdbm && $(MAKE) all | |
1762 | '; | |
1763 | } | |
1764 | ||
1765 | ||
f1387719 | 1766 | =head2 Hintsfile support |
1767 | ||
1768 | MakeMaker.pm uses the architecture specific information from | |
1769 | Config.pm. In addition it evaluates architecture specific hints files | |
1770 | in a C<hints/> directory. The hints files are expected to be named | |
1771 | like their counterparts in C<PERL_SRC/hints>, but with an C<.pl> file | |
1772 | name extension (eg. C<next_3_2.pl>). They are simply C<eval>ed by | |
1773 | MakeMaker within the WriteMakefile() subroutine, and can be used to | |
1774 | execute commands as well as to include special variables. The rules | |
1775 | which hintsfile is chosen are the same as in Configure. | |
1776 | ||
1777 | The hintsfile is eval()ed immediately after the arguments given to | |
1778 | WriteMakefile are stuffed into a hash reference $self but before this | |
1779 | reference becomes blessed. So if you want to do the equivalent to | |
1780 | override or create an attribute you would say something like | |
1781 | ||
1782 | $self->{LIBS} = ['-ldbm -lucb -lc']; | |
1783 | ||
005c1a0e AD |
1784 | =head2 Distribution Support |
1785 | ||
1786 | For authors of extensions MakeMaker provides several Makefile | |
1787 | targets. Most of the support comes from the ExtUtils::Manifest module, | |
1788 | where additional documentation can be found. | |

005c1a0e | 1804 | =item make distclean |
8e07c86e | 1805 | |
005c1a0e AD |
1806 | does a realclean first and then the distcheck. Note that this is not |
1807 | needed to build a new distribution as long as you are sure, that the | |
1808 | MANIFEST file is ok. | |
1809 | ||
1810 | =item make manifest | |

1815 | =item make distdir | |
8e07c86e | 1816 | |

1817 | Copies all the files that are in the MANIFEST file to a newly created |
1818 | directory with the name C<$(DISTNAME)-$(VERSION)>. If that directory | |

8e07c86e AD |
1821 | =item make disttest |

005c1a0e | 1826 | =item make tardist |
8e07c86e | 1827 | |
3b03c0f3 | 1828 | First does a distdir. Then a command $(PREOP) which defaults to a null |
f1387719 | 1829 | command, followed by $(TOUNIX), which defaults to a null command under |
1830 | UNIX, and will convert files in distribution directory to UNIX format | |
1831 | otherwise. Next it runs C<tar> on that directory into a tarfile and | |
3b03c0f3 | 1832 | deletes the directory. Finishes with a command $(POSTOP) which |
1833 | defaults to a null command. | |
005c1a0e AD |
1834 | |
1835 | =item make dist | |
8e07c86e | 1836 | |

1843 | =item make shdist | |
8e07c86e | 1844 | |
3b03c0f3 | 1845 | First does a distdir. Then a command $(PREOP) which defaults to a null |
1846 | command. Next it runs C<shar> on that directory into a sharfile and | |
1847 | deletes the intermediate directory again. Finishes with a command | |
1848 | $(POSTOP) which defaults to a null command. Note: For shdist to work | |
1849 | properly a C<shar> program that can handle directories is mandatory. | |
1850 | ||
1851 | =item make zipdist | |
1852 | ||
1853 | First does a distdir. Then a command $(PREOP) which defaults to a null | |
1854 | command. Runs C<$(ZIP) $(ZIPFLAGS)> on that directory into a | |
1855 | zipfile. Then deletes that directory. Finishes with a command | |
1856 | $(POSTOP) which defaults to a null command. | |

1885 | =head2 Disabling an extension |
1886 | ||
1887 | If some events detected in F<Makefile.PL> imply that there is no way | |
1888 | to create the Module, but this is a normal state of things, then you | |
1889 | can create a F<Makefile> which does nothing, but succeeds on all the | |
1890 | "usual" build targets. To do so, use | |
1891 | ||
1892 | ExtUtils::MakeMaker::WriteEmptyMakefile(); | |
1893 | ||
1894 | instead of WriteMakefile(). | |
1895 | ||
1896 | This may be useful if other modules expect this module to be I<built> | |
1897 | OK, as opposed to I<work> OK (say, this system-dependent module builds | |
1898 | in a subdirectory of some other distribution, or is listed as a | |
1899 | dependency in a CPAN::Bundle, but the functionality is supported by | |
1900 | different means on the current architecture). | |
