301The extension you are trying to build apparently is rather old and
302most probably outdated. We detect that from the fact, that a
303subroutine "writeMakefile" is called, and this subroutine is not
304supported anymore since about October 1994.

4633a7c4
LW
306Please contact the author or look into CPAN (details about CPAN can be
307found in the FAQ and at http:/www.perl.com) for a more recent version
308of the extension. If you're really desperate, you can try to change
309the subroutine name from writeMakefile to WriteMakefile and rerun
310'perl Makefile.PL', but you're most probably left alone, when you do
311so.

895=head1 DESCRIPTION
896
897This utility is designed to write a Makefile for an extension module
898from a Makefile.PL. It is based on the Makefile.SH model provided by
899Andy Dougherty and the perl5-porters.
900
901It splits the task of generating the Makefile into several subroutines
902that can be individually overridden. Each subroutine returns the text
903it wishes to have written to the Makefile.
904
f1387719
PP
905MakeMaker is object oriented. Each directory below the current
906directory that contains a Makefile.PL. Is treated as a separate
907object. This makes it possible to write an unlimited number of
908Makefiles with a single invocation of WriteMakefile().

f1387719 910=head2 How To Write A Makefile.PL
8e07c86e 911

AK
912The short answer is: Don't.
913
914 Always begin with h2xs.
915 Always begin with h2xs!
916 ALWAYS BEGIN WITH H2XS!
917
918even if you're not building around a header file, and even if you
919don't have an XS component.
920
921Run h2xs(1) before you start thinking about writing a module. For so
922called pm-only modules that consist of C<*.pm> files only, h2xs has
923the C<-X> switch. This will generate dummy files of all kinds that are
924useful for the module developer.
8e07c86e 925
f1387719 926The medium answer is:
8e07c86e 927
f1387719
PP
928 use ExtUtils::MakeMaker;
929 WriteMakefile( NAME => "Foo::Bar" );
8e07c86e 930
bab2b58e 931The long answer is the rest of the manpage :-)
005c1a0e
AD
932
933=head2 Default Makefile Behaviour
934
f1387719 935The generated Makefile enables the user of the extension to invoke
005c1a0e
AD
936
937 perl Makefile.PL # optionally "perl Makefile.PL verbose"
938 make
8e07c86e
AD
939 make test # optionally set TEST_VERBOSE=1
940 make install # See below
005c1a0e
AD
941
942The Makefile to be produced may be altered by adding arguments of the
e05e23b1 943form C<KEY=VALUE>. E.g.
005c1a0e 944
e05e23b1 945 perl Makefile.PL PREFIX=/tmp/myperl5
005c1a0e
AD
946
947Other interesting targets in the generated Makefile are
948
949 make config # to check if the Makefile is up-to-date
8e07c86e
AD
950 make clean # delete local temp files (Makefile gets renamed)
951 make realclean # delete derived files (including ./blib)
e05e23b1 952 make ci # check in all the files in the MANIFEST file
005c1a0e
AD
953 make dist # see below the Distribution Support section
954
e05e23b1
PP
955=head2 make test
956
bab2b58e 957MakeMaker checks for the existence of a file named F<test.pl> in the
e05e23b1
PP
958current directory and if it exists it adds commands to the test target
959of the generated Makefile that will execute the script with the proper
960set of perl C<-I> options.
961
962MakeMaker also checks for any files matching glob("t/*.t"). It will
963add commands to the test target of the generated Makefile that execute
964all matching files via the L<Test::Harness> module with the C<-I>
965switches set correctly.
966
bab2b58e
AK
967=head2 make testdb
968
969A useful variation of the above is the target C<testdb>. It runs the
970test under the Perl debugger (see L<perldebug>). If the file
971F<test.pl> exists in the current directory, it is used for the test.
972
973If you want to debug some other testfile, set C<TEST_FILE> variable
974thusly:
975
976 make testdb TEST_FILE=t/mytest.t
977
978By default the debugger is called using C<-d> option to perl. If you
979want to specify some other option, set C<TESTDB_SW> variable:
980
981 make testdb TESTDB_SW=-Dx
982
e05e23b1 983=head2 make install
005c1a0e 984
8e07c86e 985make alone puts all relevant files into directories that are named by
cae6c631
JD
986the macros INST_LIB, INST_ARCHLIB, INST_SCRIPT, INST_HTMLLIBDIR,
987INST_HTMLSCRIPTDIR, INST_MAN1DIR, and INST_MAN3DIR. All these default
988to something below ./blib if you are I<not> building below the perl
989source directory. If you I<are> building below the perl source,
990INST_LIB and INST_ARCHLIB default to ../../lib, and INST_SCRIPT is not
991defined.
005c1a0e 992
e05e23b1
PP
993The I<install> target of the generated Makefile copies the files found
994below each of the INST_* directories to their INSTALL*
995counterparts. Which counterparts are chosen depends on the setting of
996INSTALLDIRS according to the following table:
005c1a0e 997
cae6c631
JD
998 INSTALLDIRS set to
999 perl site
e05e23b1 1000
cae6c631
JD
1001 INST_ARCHLIB INSTALLARCHLIB INSTALLSITEARCH
1002 INST_LIB INSTALLPRIVLIB INSTALLSITELIB
1003 INST_HTMLLIBDIR INSTALLHTMLPRIVLIBDIR INSTALLHTMLSITELIBDIR
1004 INST_HTMLSCRIPTDIR INSTALLHTMLSCRIPTDIR
1005 INST_BIN INSTALLBIN
1006 INST_SCRIPT INSTALLSCRIPT
1007 INST_MAN1DIR INSTALLMAN1DIR
1008 INST_MAN3DIR INSTALLMAN3DIR
005c1a0e 1009
8e07c86e
AD
1010The INSTALL... macros in turn default to their %Config
1011($Config{installprivlib}, $Config{installarchlib}, etc.) counterparts.
005c1a0e 1012
3b03c0f3
PP
1013You can check the values of these variables on your system with
1014
bab2b58e 1015 perl '-V:install.*'
3b03c0f3 1016
f1387719
PP
1017And to check the sequence in which the library directories are
1018searched by perl, run
005c1a0e 1019
f1387719 1020 perl -le 'print join $/, @INC'
005c1a0e 1021
005c1a0e 1022
bab2b58e
AK
1023=head2 PREFIX and LIB attribute
1024
1025PREFIX and LIB can be used to set several INSTALL* attributes in one
1026go. The quickest way to install a module in a non-standard place might
1027be
1028
1029 perl Makefile.PL LIB=~/lib
005c1a0e 1030
bab2b58e 1031This will install the module's architecture-independent files into
e35b8f9e 1032~/lib, the architecture-dependent files into ~/lib/$archname.
bab2b58e
AK
1033
1034Another way to specify many INSTALL directories with a single
1035parameter is PREFIX.
005c1a0e 1036
8e07c86e 1037 perl Makefile.PL PREFIX=~
005c1a0e 1038
e35b8f9e
JH
1039This will replace the string specified by C<$Config{prefix}> in all
1040C<$Config{install*}> values.
005c1a0e 1041
bab2b58e 1042Note, that in both cases the tilde expansion is done by MakeMaker, not
e35b8f9e
JH
1043by perl by default, nor by make.
1044
1045Conflicts between parameters LIB,
1046PREFIX and the various INSTALL* arguments are resolved so that:
1047
1048=over 4
1049
1050=item *
1051
1052setting LIB overrides any setting of INSTALLPRIVLIB, INSTALLARCHLIB,
1053INSTALLSITELIB, INSTALLSITEARCH (and they are not affected by PREFIX);
1054
1055=item *
1056
1057without LIB, setting PREFIX replaces the initial C<$Config{prefix}>
1058part of those INSTALL* arguments, even if the latter are explicitly
1059set (but are set to still start with C<$Config{prefix}>).
1060
1061=back
005c1a0e 1062
005c1a0e 1063If the user has superuser privileges, and is not working on AFS
e35b8f9e 1064or relatives, then the defaults for
f1387719 1065INSTALLPRIVLIB, INSTALLARCHLIB, INSTALLSCRIPT, etc. will be appropriate,
005c1a0e
AD
1066and this incantation will be the best:
1067
1068 perl Makefile.PL; make; make test
1069 make install
1070
8e07c86e 1071make install per default writes some documentation of what has been
e05e23b1
PP
1072done into the file C<$(INSTALLARCHLIB)/perllocal.pod>. This feature
1073can be bypassed by calling make pure_install.
8e07c86e
AD
1074
1075=head2 AFS users
1076
1077will have to specify the installation directories as these most
1078probably have changed since perl itself has been installed. They will
1079have to do this by calling
1080
e05e23b1 1081 perl Makefile.PL INSTALLSITELIB=/afs/here/today \
f1387719 1082 INSTALLSCRIPT=/afs/there/now INSTALLMAN3DIR=/afs/for/manpages
8e07c86e
AD
1083 make
1084
e05e23b1
PP
1085Be careful to repeat this procedure every time you recompile an
1086extension, unless you are sure the AFS installation directories are
1087still valid.
005c1a0e 1088
8e07c86e 1089=head2 Static Linking of a new Perl Binary
005c1a0e
AD
1090
1091An extension that is built with the above steps is ready to use on
1092systems supporting dynamic loading. On systems that do not support
1093dynamic loading, any newly created extension has to be linked together
1094with the available resources. MakeMaker supports the linking process
1095by creating appropriate targets in the Makefile whenever an extension
1096is built. You can invoke the corresponding section of the makefile with
1097
1098 make perl
1099
1100That produces a new perl binary in the current directory with all
da7f727a 1101extensions linked in that can be found in INST_ARCHLIB, SITELIBEXP,
e05e23b1
PP
1102and PERL_ARCHLIB. To do that, MakeMaker writes a new Makefile, on
1103UNIX, this is called Makefile.aperl (may be system dependent). If you
1104want to force the creation of a new perl, it is recommended, that you
1105delete this Makefile.aperl, so the directories are searched-through
1106for linkable libraries again.
005c1a0e
AD
1107
1108The binary can be installed into the directory where perl normally
1109resides on your machine with
1110
1111 make inst_perl
1112
1113To produce a perl binary with a different name than C<perl>, either say
1114
1115 perl Makefile.PL MAP_TARGET=myperl
1116 make myperl
1117 make inst_perl
1118
1119or say
1120
1121 perl Makefile.PL
1122 make myperl MAP_TARGET=myperl
1123 make inst_perl MAP_TARGET=myperl
1124
1125In any case you will be prompted with the correct invocation of the
1126C<inst_perl> target that installs the new binary into INSTALLBIN.
1127
8e07c86e
AD
1128make inst_perl per default writes some documentation of what has been
1129done into the file C<$(INSTALLARCHLIB)/perllocal.pod>. This
1130can be bypassed by calling make pure_inst_perl.
005c1a0e 1131
e05e23b1
PP
1132Warning: the inst_perl: target will most probably overwrite your
1133existing perl binary. Use with care!
005c1a0e 1134
8e07c86e
AD
1135Sometimes you might want to build a statically linked perl although
1136your system supports dynamic loading. In this case you may explicitly
1137set the linktype with the invocation of the Makefile.PL or make:
1138
1139 perl Makefile.PL LINKTYPE=static # recommended
1140
1141or
1142
1143 make LINKTYPE=static # works on most systems
1144
005c1a0e
AD
1145=head2 Determination of Perl Library and Installation Locations
1146
1147MakeMaker needs to know, or to guess, where certain things are
e05e23b1
PP
1148located. Especially INST_LIB and INST_ARCHLIB (where to put the files
1149during the make(1) run), PERL_LIB and PERL_ARCHLIB (where to read
1150existing modules from), and PERL_INC (header files and C<libperl*.*>).
005c1a0e
AD
1151
1152Extensions may be built either using the contents of the perl source
e05e23b1
PP
1153directory tree or from the installed perl library. The recommended way
1154is to build extensions after you have run 'make install' on perl
1155itself. You can do that in any directory on your hard disk that is not
1156below the perl source tree. The support for extensions below the ext
1157directory of the perl distribution is only good for the standard
1158extensions that come with perl.
005c1a0e
AD
1159
1160If an extension is being built below the C<ext/> directory of the perl
e05e23b1
PP
1161source then MakeMaker will set PERL_SRC automatically (e.g.,
1162C<../..>). If PERL_SRC is defined and the extension is recognized as
1163a standard extension, then other variables default to the following:
005c1a0e
AD
1164
1165 PERL_INC = PERL_SRC
1166 PERL_LIB = PERL_SRC/lib
1167 PERL_ARCHLIB = PERL_SRC/lib
1168 INST_LIB = PERL_LIB
1169 INST_ARCHLIB = PERL_ARCHLIB
1170
1171If an extension is being built away from the perl source then MakeMaker
1172will leave PERL_SRC undefined and default to using the installed copy
1173of the perl library. The other variables default to the following:
1174
e05e23b1
PP
1175 PERL_INC = $archlibexp/CORE
1176 PERL_LIB = $privlibexp
1177 PERL_ARCHLIB = $archlibexp
1178 INST_LIB = ./blib/lib
1179 INST_ARCHLIB = ./blib/arch
005c1a0e
AD
1180
1181If perl has not yet been installed then PERL_SRC can be defined on the
1182command line as shown in the previous section.
1183
005c1a0e 1184
f1387719 1185=head2 Which architecture dependent directory?
005c1a0e 1186
f1387719
PP
1187If you don't want to keep the defaults for the INSTALL* macros,
1188MakeMaker helps you to minimize the typing needed: the usual
1189relationship between INSTALLPRIVLIB and INSTALLARCHLIB is determined
1190by Configure at perl compilation time. MakeMaker supports the user who
1191sets INSTALLPRIVLIB. If INSTALLPRIVLIB is set, but INSTALLARCHLIB not,
1192then MakeMaker defaults the latter to be the same subdirectory of
1193INSTALLPRIVLIB as Configure decided for the counterparts in %Config ,
1194otherwise it defaults to INSTALLPRIVLIB. The same relationship holds
1195for INSTALLSITELIB and INSTALLSITEARCH.
005c1a0e 1196
f1387719
PP
1197MakeMaker gives you much more freedom than needed to configure
1198internal variables and get different results. It is worth to mention,
1199that make(1) also lets you configure most of the variables that are
1200used in the Makefile. But in the majority of situations this will not
a7665c5e 1201be necessary, and should only be done if the author of a package
f1387719 1202recommends it (or you know what you're doing).

1211=item ABSTRACT
1212
1213One line description of the module. Will be included in PPD file.
1214
1215=item ABSTRACT_FROM
1216
1217Name of the file that contains the package description. MakeMaker looks
1218for a line in the POD matching /^($package\s-\s)(.*)/. This is typically
1219the first line in the "=head1 NAME" section. $2 becomes the abstract.
1220
e35b8f9e
JH
1221=item AUTHOR
1222
1223String containing name (and email address) of package author(s). Is used
1224in PPD (Perl Package Description) files for PPM (Perl Package Manager).
1225
875fa795
JD
1226=item BINARY_LOCATION
1227
1228Used when creating PPD files for binary packages. It can be set to a
1229full or relative path or URL to the binary archive for a particular
1230architecture. For example:
1231
1232 perl Makefile.PL BINARY_LOCATION=x86/Agent.tar.gz
1233
1234builds a PPD package that references a binary of the C<Agent> package,
20e08411 1235located in the C<x86> directory relative to the PPD itself.
8e07c86e 1236

8e07c86e 1238
864a5fa8
AD
1239Ref to array of *.c file names. Initialised from a directory scan
1240and the values portion of the XS attribute hash. This is not
1241currently used by MakeMaker but may be handy in Makefile.PLs.
8e07c86e 1242

1736=item PM_FILTER
1737
1738A filter program, in the traditional Unix sense (input from stdin, output
1739to stdout) that is passed on each .pm file during the build (in the
1740pm_to_blib() phase). It is empty by default, meaning no filtering is done.
1741
1742Great care is necessary when defining the command if quoting needs to be
1743done. For instance, you would need to say:
1744
1745 {'PM_FILTER' => 'grep -v \\"^\\#\\"'}
1746
1747to remove all the leading coments on the fly during the build. The
1748extra \\ are necessary, unfortunately, because this variable is interpolated
1749within the context of a Perl program built on the command line, and double
1750quotes are what is used with the -e switch to build that command line. The
1751# is escaped for the Makefile, since what is going to be generated will then
1752be:
1753
1754 PM_FILTER = grep -v \"^\#\"
1755
1756Without the \\ before the #, we'd have the start of a Makefile comment,
1757and the macro would be incorrectly defined.

1985=head2 Overriding MakeMaker Methods
1986
1987If you cannot achieve the desired Makefile behaviour by specifying
1988attributes you may define private subroutines in the Makefile.PL.
1989Each subroutines returns the text it wishes to have written to
1990the Makefile. To override a section of the Makefile you can
1991either say:
1992
1993 sub MY::c_o { "new literal text" }
1994
1995or you can edit the default by saying something like:
1996
8e07c86e 1997 sub MY::c_o {
14870ecd
CS
1998 package MY; # so that "SUPER" works right
1999 my $inherited = shift->SUPER::c_o(@_);

2004If you are running experiments with embedding perl as a library into

2007for embedding.

2026=head2 Hintsfile support
2027
2028MakeMaker.pm uses the architecture specific information from
2029Config.pm. In addition it evaluates architecture specific hints files
2030in a C<hints/> directory. The hints files are expected to be named
2031like their counterparts in C<PERL_SRC/hints>, but with an C<.pl> file
2032name extension (eg. C<next_3_2.pl>). They are simply C<eval>ed by
2033MakeMaker within the WriteMakefile() subroutine, and can be used to
2034execute commands as well as to include special variables. The rules
2035which hintsfile is chosen are the same as in Configure.
2036
2037The hintsfile is eval()ed immediately after the arguments given to
2038WriteMakefile are stuffed into a hash reference $self but before this
2039reference becomes blessed. So if you want to do the equivalent to
2040override or create an attribute you would say something like
2041
2042 $self->{LIBS} = ['-ldbm -lucb -lc'];

2146
2147If some events detected in F<Makefile.PL> imply that there is no way
2148to create the Module, but this is a normal state of things, then you
2149can create a F<Makefile> which does nothing, but succeeds on all the
2150"usual" build targets. To do so, use
2151
2152 ExtUtils::MakeMaker::WriteEmptyMakefile();
2153
2154instead of WriteMakefile().
2155
2156This may be useful if other modules expect this module to be I<built>
2157OK, as opposed to I<work> OK (say, this system-dependent module builds
2158in a subdirectory of some other distribution, or is listed as a
2159dependency in a CPAN::Bundle, but the functionality is supported by
