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340 most probably outdated.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.
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

832 ExtUtils::MakeMaker - create an extension Makefile
836 C<use ExtUtils::MakeMaker;>
838 C<WriteMakefile( ATTRIBUTE =E<gt> VALUE [, ...] );>
842 C<MM-E<gt>new(\%att)-E<gt>flush;>
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.
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.
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().
859 =head2 How To Write A Makefile.PL
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
867 The medium answer is:
869 use ExtUtils::MakeMaker;
870 WriteMakefile( NAME => "Foo::Bar" );
872 The long answer is below.
874 =head2 Default Makefile Behaviour
876 The generated Makefile enables the user of the extension to invoke
878 perl Makefile.PL # optionally "perl Makefile.PL verbose"
880 make test # optionally set TEST_VERBOSE=1
881 make install # See below
883 The Makefile to be produced may be altered by adding arguments of the
884 form C<KEY=VALUE>. E.g.
886 perl Makefile.PL PREFIX=/tmp/myperl5
888 Other interesting targets in the generated Makefile are
890 make config # to check if the Makefile is up-to-date
891 make clean # delete local temp files (Makefile gets renamed)
892 make realclean # delete derived files (including ./blib)
893 make ci # check in all the files in the MANIFEST file
894 make dist # see below the Distribution Support section
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.
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.
910 make alone puts all relevant files into directories that are named by
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>
914 building below the perl source, INST_LIB and INST_ARCHLIB default to
915 ../../lib, and INST_SCRIPT is not defined.
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:
925 INST_ARCHLIB INSTALLARCHLIB INSTALLSITEARCH
926 INST_LIB INSTALLPRIVLIB INSTALLSITELIB
928 INST_SCRIPT INSTALLSCRIPT
929 INST_MAN1DIR INSTALLMAN1DIR
930 INST_MAN3DIR INSTALLMAN3DIR
932 The INSTALL... macros in turn default to their %Config
933 ($Config{installprivlib}, $Config{installarchlib}, etc.) counterparts.
935 You can check the values of these variables on your system with
937 perl -MConfig -le 'print join $/, map
938 sprintf("%20s: %s", $_, $Config{$_}),
939 grep /^install/, keys %Config'
941 And to check the sequence in which the library directories are
942 searched by perl, run
944 perl -le 'print join $/, @INC'
947 =head2 PREFIX attribute
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
952 perl Makefile.PL PREFIX=~
954 This will replace the string specified by $Config{prefix} in all
955 $Config{install*} values.
957 Note, that the tilde expansion is done by MakeMaker, not by perl by
958 default, nor by make.
960 If the user has superuser privileges, and is not working on AFS
961 (Andrew File System) or relatives, then the defaults for
962 INSTALLPRIVLIB, INSTALLARCHLIB, INSTALLSCRIPT, etc. will be appropriate,
963 and this incantation will be the best:
965 perl Makefile.PL; make; make test
968 make install per default writes some documentation of what has been
969 done into the file C<$(INSTALLARCHLIB)/perllocal.pod>. This feature
970 can be bypassed by calling make pure_install.
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
978 perl Makefile.PL INSTALLSITELIB=/afs/here/today \
979 INSTALLSCRIPT=/afs/there/now INSTALLMAN3DIR=/afs/for/manpages
982 Be careful to repeat this procedure every time you recompile an
983 extension, unless you are sure the AFS installation directories are
986 =head2 Static Linking of a new Perl Binary
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
997 That produces a new perl binary in the current directory with all
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.
1005 The binary can be installed into the directory where perl normally
1006 resides on your machine with
1010 To produce a perl binary with a different name than C<perl>, either say
1012 perl Makefile.PL MAP_TARGET=myperl
1019 make myperl MAP_TARGET=myperl
1020 make inst_perl MAP_TARGET=myperl
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.
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.
1029 Warning: the inst_perl: target will most probably overwrite your
1030 existing perl binary. Use with care!
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:
1036 perl Makefile.PL LINKTYPE=static # recommended
1040 make LINKTYPE=static # works on most systems
1042 =head2 Determination of Perl Library and Installation Locations
1044 MakeMaker needs to know, or to guess, where certain things are
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*.*>).
1049 Extensions may be built either using the contents of the perl source
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.
1057 If an extension is being built below the C<ext/> directory of the perl
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:
1063 PERL_LIB = PERL_SRC/lib
1064 PERL_ARCHLIB = PERL_SRC/lib
1066 INST_ARCHLIB = PERL_ARCHLIB
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:
1072 PERL_INC = $archlibexp/CORE
1073 PERL_LIB = $privlibexp
1074 PERL_ARCHLIB = $archlibexp
1075 INST_LIB = ./blib/lib
1076 INST_ARCHLIB = ./blib/arch
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.
1082 =head2 Which architecture dependent directory?
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.
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
1103 The following attributes can be specified as arguments to WriteMakefile()
1104 or as NAME=VALUE pairs on the command line:
1108 # The following "=item C" is used by the attrib_help routine
1109 # likewise the "=back" below. So be careful when changing it!
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.
1121 Arrayref. E.g. [qw(archname manext)] defines ARCHNAME & MANEXT from
1122 config.sh. MakeMaker will add to CONFIG the following values anyway:
1142 CODE reference. The subroutine should return a hash reference. The
1143 hash may contain further attributes, e.g. {LIBS => ...}, that have to
1144 be determined by some evaluation method.
1148 Something like C<"-DHAVE_UNISTD_H">
1152 Ref to array of subdirectories containing Makefile.PLs e.g. [ 'sdbm'
1157 Your name for distributing the package (by tar file). This defaults to
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
1169 {"$(NAME)" => ["boot_$(NAME)" ] }
1173 {"RPC" => [qw( boot_rpcb rpcb_gettime getnetconfigent )],
1174 "NetconfigPtr" => [ 'DESTROY'] }
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 ) ])
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 ) ] )
1189 This attribute may be most useful when specified as a string on the
1190 commandline: perl Makefile.PL EXCLUDE_EXT='Socket Safe'
1194 Ref to array of executable files. The files will be copied to the
1195 INST_SCRIPT directory. Make realclean will delete them from there
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.
1205 =item FIRST_MAKEFILE
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.
1213 Perl binary able to run this extension.
1217 Ref to array of *.h file names. Similar to C.
1221 Include file dirs eg: C<"-I/usr/5include -I/path/to/inc">
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 ) ])
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.
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'
1238 =item INSTALLARCHLIB
1240 Used by 'make install', which copies files from INST_ARCHLIB to this
1241 directory if INSTALLDIRS is set to perl.
1245 Directory to install binary files (e.g. tkperl) into.
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.
1254 =item INSTALLMAN1DIR
1256 This directory gets the man pages at 'make install' time. Defaults to
1257 $Config{installman1dir}.
1259 =item INSTALLMAN3DIR
1261 This directory gets the man pages at 'make install' time. Defaults to
1262 $Config{installman3dir}.
1264 =item INSTALLPRIVLIB
1266 Used by 'make install', which copies files from INST_LIB to this
1267 directory if INSTALLDIRS is set to perl.
1271 Used by 'make install' which copies files from INST_SCRIPT to this
1274 =item INSTALLSITELIB
1276 Used by 'make install', which copies files from INST_LIB to this
1277 directory if INSTALLDIRS is set to site (default).
1279 =item INSTALLSITEARCH
1281 Used by 'make install', which copies files from INST_ARCHLIB to this
1282 directory if INSTALLDIRS is set to site (default).
1286 Same as INST_LIB for architecture dependent files.
1290 Directory to put real binary files during 'make'. These will be copied
1291 to INSTALLBIN during 'make install'
1295 Old name for INST_SCRIPT. Deprecated. Please use INST_SCRIPT if you
1300 Directory where we put library files of this extension while building
1305 Directory to hold the man pages at 'make' time
1309 Directory to hold the man pages at 'make' time
1313 Directory, where executable files should be installed during
1314 'make'. Defaults to "./blib/bin", just to have a dummy location during
1315 testing. make install will copy the files in INST_SCRIPT to
1320 defaults to "$(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
1326 The filename of the perllibrary that will be used together with this
1327 extension. Defaults to libperl.a.
1331 An anonymous array of alternative library
1332 specifications to be searched for (in order) until
1333 at least one library is found. E.g.
1335 'LIBS' => ["-lgdbm", "-ldbm -lfoo", "-L/path -ldbm.nfs"]
1337 Mind, that any element of the array
1338 contains a complete set of arguments for the ld
1339 command. So do not specify
1341 'LIBS' => ["-ltcl", "-ltk", "-lX11"]
1343 See ODBM_File/Makefile.PL for an example, where an array is needed. If
1344 you specify a scalar as in
1346 'LIBS' => "-ltcl -ltk -lX11"
1348 MakeMaker will turn it into an array with one element.
1352 'static' or 'dynamic' (default unless usedl=undef in
1353 config.sh). Should only be used to force static linking (also see
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.
1364 The name of the Makefile to be produced.
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
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
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
1387 If the extension links to a library that it builds set this to the
1388 name of the library (see SDBM_File)
1392 Perl module name for this extension (DBD::Oracle). This will default
1393 to the directory name but should be explicitly defined in the
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.
1405 Defaults to C<@>. By setting it to an empty string you can generate a
1406 Makefile that echos all commands. Mainly used in debugging MakeMaker
1411 Boolean. Attribute to inhibit descending into subdirectories.
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"
1421 Defaults to C<-O>. Set it to C<-g> to turn debugging on. The flag is
1422 passed to subdirectory makes.
1426 Perl binary for tasks that can be done by miniperl
1430 The call to the program that is able to compile perlmain.c. Defaults
1435 Same as above for architecture dependent files
1439 Directory containing the Perl library to use.
1443 Directory containing the Perl source code (use of this should be
1444 avoided, it may be undefined)
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.
1452 {'foobar.PL' => 'foobar'}
1454 The *.PL files are expected to produce output to the target files
1459 Hashref of .pm files and *.pl files to be installed. e.g.
1461 {'name_of_file.pm' => '$(INST_LIBDIR)/install_as.pm'}
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.
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.
1478 Can be used to set the three INSTALL* attributes in one go (except for
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
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.
1494 Arryref. E.g. [qw(name1 name2)] skip (do not write) sections of the
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.
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.
1510 Your version number for distributing the package. This defaults to
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
1521 /(\$[\w:]*\bVERSION)\b.*=/
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.:
1528 ( $VERSION ) = '$Revision: 1.201 $ ' =~ /\$Revision:\s+([^\s]+)/;
1529 $FOO::VERSION = '1.10';
1531 but these will fail:
1533 my $VERSION = '1.01';
1534 local $VERSION = '1.02';
1535 local $FOO::VERSION = '1.30';
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.
1543 Hashref of .xs files. MakeMaker will default this. e.g.
1545 {'name_of_file.xs' => 'name_of_file.c'}
1547 The .c files will automatically be included in the list of files
1548 deleted by a make clean.
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
1558 May be set to an empty string, which is identical to C<-prototypes>, or
1559 C<-noprototypes>. See the xsubpp documentation for details. MakeMaker
1560 defaults to the empty string.
1564 Your version number for the .xs file of this package. This defaults
1565 to the value of the VERSION attribute.
1569 =head2 Additional lowercase attributes
1571 can be used to pass parameters to the methods which implement that
1572 part of the Makefile.
1578 {FILES => "*.xyz foo"}
1582 {ANY_TARGET => ANY_DEPENDECY, ...}
1586 {TARFLAGS => 'cvfF', COMPRESS => 'gzip', SUFFIX => 'gz',
1587 SHAR => 'shar -m', DIST_CP => 'ln', ZIP => '/bin/zip',
1588 ZIPFLAGS => '-rl', DIST_DEFAULT => 'private tardist' }
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'.
1599 {ARMAYBE => 'ar', OTHERLDFLAGS => '...', INST_DYNAMIC_DEP => '...'}
1603 Deprecated as of MakeMaker 5.23. See L<ExtUtils::MM_Unix/pm_to_blib>.
1607 {LINKTYPE => 'static', 'dynamic' or ''}
1609 NB: Extensions that have nothing but *.pm files had to say
1613 with Pre-5.0 MakeMakers. Since version 5.00 of MakeMaker such a line
1614 can be deleted safely. MakeMaker recognizes, when there's nothing to

1637 =head2 Overriding MakeMaker Methods
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
1645 sub MY::c_o { "new literal text" }
1647 or you can edit the default by saying something like:
1650 my($inherited) = shift->SUPER::c_o(@_);
1651 $inherited =~ s/old text/new text/;
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
1660 If you still need a different solution, try to develop another
1661 subroutine, that fits your needs and submit the diffs to
1662 F<perl5-porters@nicoh.com> or F<comp.lang.perl.misc> as appropriate.
1664 For a complete description of all MakeMaker methods see L<ExtUtils::MM_Unix>.
1666 Here is a simple example of how to add a new target to the generated
1671 $(MYEXTLIB): sdbm/Makefile
1672 cd sdbm && $(MAKE) all
1677 =head2 Hintsfile support
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.
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
1693 $self->{LIBS} = ['-ldbm -lucb -lc'];
1695 =head2 Distribution Support
1697 For authors of extensions MakeMaker provides several Makefile
1698 targets. Most of the support comes from the ExtUtils::Manifest module,
1699 where additional documentation can be found.
1703 =item make distcheck
1705 reports which files are below the build directory but not in the
1706 MANIFEST file and vice versa. (See ExtUtils::Manifest::fullcheck() for
1709 =item make skipcheck
1711 reports which files are skipped due to the entries in the
1712 C<MANIFEST.SKIP> file (See ExtUtils::Manifest::skipcheck() for
1715 =item make distclean
1717 does a realclean first and then the distcheck. Note that this is not
1718 needed to build a new distribution as long as you are sure, that the
1719 MANIFEST file is ok.
1723 rewrites the MANIFEST file, adding all remaining files found (See
1724 ExtUtils::Manifest::mkmanifest() for details)
1728 Copies all the files that are in the MANIFEST file to a newly created
1729 directory with the name C<$(DISTNAME)-$(VERSION)>. If that directory
1730 exists, it will be removed first.
1734 Makes a distdir first, and runs a C<perl Makefile.PL>, a make, and
1735 a make test in that directory.
1739 First does a distdir. Then a command $(PREOP) which defaults to a null
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
1743 deletes the directory. Finishes with a command $(POSTOP) which
1744 defaults to a null command.
1748 Defaults to $(DIST_DEFAULT) which in turn defaults to tardist.
1750 =item make uutardist
1752 Runs a tardist first and uuencodes the tarfile.
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.
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.
1771 Does a $(CI) and a $(RCS_LABEL) on all files in the MANIFEST file.
1775 Customization of the dist targets can be done by specifying a hash
1776 reference to the dist attribute of the WriteMakefile call. The
1777 following parameters are recognized:
1780 COMPRESS ('compress')
1783 TO_UNIX (depends on the system)
1784 RCS_LABEL ('rcs -q -Nv$(VERSION_SYM):')
1794 WriteMakefile( 'dist' => { COMPRESS=>"gzip", SUFFIX=>"gz" })
