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339 most probably outdated.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

831 ExtUtils::MakeMaker - create an extension Makefile
835 C<use ExtUtils::MakeMaker;>
837 C<WriteMakefile( ATTRIBUTE =E<gt> VALUE [, ...] );>
841 C<MM-E<gt>new(\%att)-E<gt>flush;>
845 This utility is designed to write a Makefile for an extension module
846 from a Makefile.PL. It is based on the Makefile.SH model provided by
847 Andy Dougherty and the perl5-porters.
849 It splits the task of generating the Makefile into several subroutines
850 that can be individually overridden. Each subroutine returns the text
851 it wishes to have written to the Makefile.
853 MakeMaker is object oriented. Each directory below the current
854 directory that contains a Makefile.PL. Is treated as a separate
855 object. This makes it possible to write an unlimited number of
856 Makefiles with a single invocation of WriteMakefile().
858 =head2 How To Write A Makefile.PL
860 The short answer is: Don't. Run h2xs(1) before you start thinking
861 about writing a module. For so called pm-only modules that consist of
862 C<*.pm> files only, h2xs has the very useful C<-X> switch. This will
863 generate dummy files of all kinds that are useful for the module
866 The medium answer is:
868 use ExtUtils::MakeMaker;
869 WriteMakefile( NAME => "Foo::Bar" );
871 The long answer is below.
873 =head2 Default Makefile Behaviour
875 The generated Makefile enables the user of the extension to invoke
877 perl Makefile.PL # optionally "perl Makefile.PL verbose"
879 make test # optionally set TEST_VERBOSE=1
880 make install # See below
882 The Makefile to be produced may be altered by adding arguments of the
883 form C<KEY=VALUE>. E.g.
885 perl Makefile.PL PREFIX=/tmp/myperl5
887 Other interesting targets in the generated Makefile are
889 make config # to check if the Makefile is up-to-date
890 make clean # delete local temp files (Makefile gets renamed)
891 make realclean # delete derived files (including ./blib)
892 make ci # check in all the files in the MANIFEST file
893 make dist # see below the Distribution Support section
897 MakeMaker checks for the existence of a file named "test.pl" in the
898 current directory and if it exists it adds commands to the test target
899 of the generated Makefile that will execute the script with the proper
900 set of perl C<-I> options.
902 MakeMaker also checks for any files matching glob("t/*.t"). It will
903 add commands to the test target of the generated Makefile that execute
904 all matching files via the L<Test::Harness> module with the C<-I>
905 switches set correctly.
909 make alone puts all relevant files into directories that are named by
910 the macros INST_LIB, INST_ARCHLIB, INST_SCRIPT, INST_MAN1DIR, and
911 INST_MAN3DIR. All these default to something below ./blib if you are
912 I<not> building below the perl source directory. If you I<are>
913 building below the perl source, INST_LIB and INST_ARCHLIB default to
914 ../../lib, and INST_SCRIPT is not defined.
916 The I<install> target of the generated Makefile copies the files found
917 below each of the INST_* directories to their INSTALL*
918 counterparts. Which counterparts are chosen depends on the setting of
919 INSTALLDIRS according to the following table:
924 INST_ARCHLIB INSTALLARCHLIB INSTALLSITEARCH
925 INST_LIB INSTALLPRIVLIB INSTALLSITELIB
927 INST_SCRIPT INSTALLSCRIPT
928 INST_MAN1DIR INSTALLMAN1DIR
929 INST_MAN3DIR INSTALLMAN3DIR
931 The INSTALL... macros in turn default to their %Config
932 ($Config{installprivlib}, $Config{installarchlib}, etc.) counterparts.
934 You can check the values of these variables on your system with
936 perl -MConfig -le 'print join $/, map
937 sprintf("%20s: %s", $_, $Config{$_}),
938 grep /^install/, keys %Config'
940 And to check the sequence in which the library directories are
941 searched by perl, run
943 perl -le 'print join $/, @INC'
946 =head2 PREFIX attribute
948 The PREFIX attribute can be used to set the INSTALL* attributes in one
949 go. The quickest way to install a module in a non-standard place
951 perl Makefile.PL PREFIX=~
953 This will replace the string specified by $Config{prefix} in all
954 $Config{install*} values.
956 Note, that the tilde expansion is done by MakeMaker, not by perl by
957 default, nor by make.
959 If the user has superuser privileges, and is not working on AFS
960 (Andrew File System) or relatives, then the defaults for
961 INSTALLPRIVLIB, INSTALLARCHLIB, INSTALLSCRIPT, etc. will be appropriate,
962 and this incantation will be the best:
964 perl Makefile.PL; make; make test
967 make install per default writes some documentation of what has been
968 done into the file C<$(INSTALLARCHLIB)/perllocal.pod>. This feature
969 can be bypassed by calling make pure_install.
973 will have to specify the installation directories as these most
974 probably have changed since perl itself has been installed. They will
975 have to do this by calling
977 perl Makefile.PL INSTALLSITELIB=/afs/here/today \
978 INSTALLSCRIPT=/afs/there/now INSTALLMAN3DIR=/afs/for/manpages
981 Be careful to repeat this procedure every time you recompile an
982 extension, unless you are sure the AFS installation directories are
985 =head2 Static Linking of a new Perl Binary
987 An extension that is built with the above steps is ready to use on
988 systems supporting dynamic loading. On systems that do not support
989 dynamic loading, any newly created extension has to be linked together
990 with the available resources. MakeMaker supports the linking process
991 by creating appropriate targets in the Makefile whenever an extension
992 is built. You can invoke the corresponding section of the makefile with
996 That produces a new perl binary in the current directory with all
997 extensions linked in that can be found in INST_ARCHLIB , SITELIBEXP,
998 and PERL_ARCHLIB. To do that, MakeMaker writes a new Makefile, on
999 UNIX, this is called Makefile.aperl (may be system dependent). If you
1000 want to force the creation of a new perl, it is recommended, that you
1001 delete this Makefile.aperl, so the directories are searched-through
1002 for linkable libraries again.
1004 The binary can be installed into the directory where perl normally
1005 resides on your machine with
1009 To produce a perl binary with a different name than C<perl>, either say
1011 perl Makefile.PL MAP_TARGET=myperl
1018 make myperl MAP_TARGET=myperl
1019 make inst_perl MAP_TARGET=myperl
1021 In any case you will be prompted with the correct invocation of the
1022 C<inst_perl> target that installs the new binary into INSTALLBIN.
1024 make inst_perl per default writes some documentation of what has been
1025 done into the file C<$(INSTALLARCHLIB)/perllocal.pod>. This
1026 can be bypassed by calling make pure_inst_perl.
1028 Warning: the inst_perl: target will most probably overwrite your
1029 existing perl binary. Use with care!
1031 Sometimes you might want to build a statically linked perl although
1032 your system supports dynamic loading. In this case you may explicitly
1033 set the linktype with the invocation of the Makefile.PL or make:
1035 perl Makefile.PL LINKTYPE=static # recommended
1039 make LINKTYPE=static # works on most systems
1041 =head2 Determination of Perl Library and Installation Locations
1043 MakeMaker needs to know, or to guess, where certain things are
1044 located. Especially INST_LIB and INST_ARCHLIB (where to put the files
1045 during the make(1) run), PERL_LIB and PERL_ARCHLIB (where to read
1046 existing modules from), and PERL_INC (header files and C<libperl*.*>).
1048 Extensions may be built either using the contents of the perl source
1049 directory tree or from the installed perl library. The recommended way
1050 is to build extensions after you have run 'make install' on perl
1051 itself. You can do that in any directory on your hard disk that is not
1052 below the perl source tree. The support for extensions below the ext
1053 directory of the perl distribution is only good for the standard
1054 extensions that come with perl.
1056 If an extension is being built below the C<ext/> directory of the perl
1057 source then MakeMaker will set PERL_SRC automatically (e.g.,
1058 C<../..>). If PERL_SRC is defined and the extension is recognized as
1059 a standard extension, then other variables default to the following:
1062 PERL_LIB = PERL_SRC/lib
1063 PERL_ARCHLIB = PERL_SRC/lib
1065 INST_ARCHLIB = PERL_ARCHLIB
1067 If an extension is being built away from the perl source then MakeMaker
1068 will leave PERL_SRC undefined and default to using the installed copy
1069 of the perl library. The other variables default to the following:
1071 PERL_INC = $archlibexp/CORE
1072 PERL_LIB = $privlibexp
1073 PERL_ARCHLIB = $archlibexp
1074 INST_LIB = ./blib/lib
1075 INST_ARCHLIB = ./blib/arch
1077 If perl has not yet been installed then PERL_SRC can be defined on the
1078 command line as shown in the previous section.
1081 =head2 Which architecture dependent directory?
1083 If you don't want to keep the defaults for the INSTALL* macros,
1084 MakeMaker helps you to minimize the typing needed: the usual
1085 relationship between INSTALLPRIVLIB and INSTALLARCHLIB is determined
1086 by Configure at perl compilation time. MakeMaker supports the user who
1087 sets INSTALLPRIVLIB. If INSTALLPRIVLIB is set, but INSTALLARCHLIB not,
1088 then MakeMaker defaults the latter to be the same subdirectory of
1089 INSTALLPRIVLIB as Configure decided for the counterparts in %Config ,
1090 otherwise it defaults to INSTALLPRIVLIB. The same relationship holds
1091 for INSTALLSITELIB and INSTALLSITEARCH.
1093 MakeMaker gives you much more freedom than needed to configure
1094 internal variables and get different results. It is worth to mention,
1095 that make(1) also lets you configure most of the variables that are
1096 used in the Makefile. But in the majority of situations this will not
1097 be necessary, and should only be done, if the author of a package
1098 recommends it (or you know what you're doing).
1100 =head2 Using Attributes and Parameters
1102 The following attributes can be specified as arguments to WriteMakefile()
1103 or as NAME=VALUE pairs on the command line:
1107 # The following "=item C" is used by the attrib_help routine
1108 # likewise the "=back" below. So be careful when changing it!
1114 Ref to array of *.c file names. Initialised from a directory scan
1115 and the values portion of the XS attribute hash. This is not
1116 currently used by MakeMaker but may be handy in Makefile.PLs.
1120 Arrayref. E.g. [qw(archname manext)] defines ARCHNAME & MANEXT from
1121 config.sh. MakeMaker will add to CONFIG the following values anyway:
1141 CODE reference. The subroutine should return a hash reference. The
1142 hash may contain further attributes, e.g. {LIBS => ...}, that have to
1143 be determined by some evaluation method.
1147 Something like C<"-DHAVE_UNISTD_H">
1151 Ref to array of subdirectories containing Makefile.PLs e.g. [ 'sdbm'
1156 Your name for distributing the package (by tar file). This defaults to
1161 Hashref of symbol names for routines to be made available as
1162 universal symbols. Each key/value pair consists of the package name
1163 and an array of routine names in that package. Used only under AIX
1164 (export lists) and VMS (linker options) at present. The routine
1165 names supplied will be expanded in the same way as XSUB names are
1166 expanded by the XS() macro. Defaults to
1168 {"$(NAME)" => ["boot_$(NAME)" ] }
1172 {"RPC" => [qw( boot_rpcb rpcb_gettime getnetconfigent )],
1173 "NetconfigPtr" => [ 'DESTROY'] }
1177 Array of symbol names for variables to be made available as
1178 universal symbols. Used only under AIX (export lists) and VMS
1179 (linker options) at present. Defaults to []. (e.g. [ qw(
1180 Foo_version Foo_numstreams Foo_tree ) ])
1184 Array of extension names to exclude when doing a static build. This
1185 is ignored if INCLUDE_EXT is present. Consult INCLUDE_EXT for more
1186 details. (e.g. [ qw( Socket POSIX ) ] )
1188 This attribute may be most useful when specified as a string on the
1189 commandline: perl Makefile.PL EXCLUDE_EXT='Socket Safe'
1193 Ref to array of executable files. The files will be copied to the
1194 INST_SCRIPT directory. Make realclean will delete them from there
1199 In general any generated Makefile checks for the current version of
1200 MakeMaker and the version the Makefile was built under. If NO_VC is
1201 set, the version check is neglected. Do not write this into your
1202 Makefile.PL, use it interactively instead.
1204 =item FIRST_MAKEFILE
1206 The name of the Makefile to be produced. Defaults to the contents of
1207 MAKEFILE, but can be overridden. This is used for the second Makefile
1208 that will be produced for the MAP_TARGET.
1212 Perl binary able to run this extension.
1216 Ref to array of *.h file names. Similar to C.
1220 Include file dirs eg: C<"-I/usr/5include -I/path/to/inc">
1224 Array of extension names to be included when doing a static build.
1225 MakeMaker will normally build with all of the installed extensions when
1226 doing a static build, and that is usually the desired behavior. If
1227 INCLUDE_EXT is present then MakeMaker will build only with those extensions
1228 which are explicitly mentioned. (e.g. [ qw( Socket POSIX ) ])
1230 It is not necessary to mention DynaLoader or the current extension when
1231 filling in INCLUDE_EXT. If the INCLUDE_EXT is mentioned but is empty then
1232 only DynaLoader and the current extension will be included in the build.
1234 This attribute may be most useful when specified as a string on the
1235 commandline: perl Makefile.PL INCLUDE_EXT='POSIX Socket Devel::Peek'
1237 =item INSTALLARCHLIB
1239 Used by 'make install', which copies files from INST_ARCHLIB to this
1240 directory if INSTALLDIRS is set to perl.
1244 Directory to install binary files (e.g. tkperl) into.
1248 Determines which of the two sets of installation directories to
1249 choose: installprivlib and installarchlib versus installsitelib and
1250 installsitearch. The first pair is chosen with INSTALLDIRS=perl, the
1251 second with INSTALLDIRS=site. Default is site.
1253 =item INSTALLMAN1DIR
1255 This directory gets the man pages at 'make install' time. Defaults to
1256 $Config{installman1dir}.
1258 =item INSTALLMAN3DIR
1260 This directory gets the man pages at 'make install' time. Defaults to
1261 $Config{installman3dir}.
1263 =item INSTALLPRIVLIB
1265 Used by 'make install', which copies files from INST_LIB to this
1266 directory if INSTALLDIRS is set to perl.
1270 Used by 'make install' which copies files from INST_SCRIPT to this
1273 =item INSTALLSITELIB
1275 Used by 'make install', which copies files from INST_LIB to this
1276 directory if INSTALLDIRS is set to site (default).
1278 =item INSTALLSITEARCH
1280 Used by 'make install', which copies files from INST_ARCHLIB to this
1281 directory if INSTALLDIRS is set to site (default).
1285 Same as INST_LIB for architecture dependent files.
1289 Directory to put real binary files during 'make'. These will be copied
1290 to INSTALLBIN during 'make install'
1294 Old name for INST_SCRIPT. Deprecated. Please use INST_SCRIPT if you
1299 Directory where we put library files of this extension while building
1304 Directory to hold the man pages at 'make' time
1308 Directory to hold the man pages at 'make' time
1312 Directory, where executable files should be installed during
1313 'make'. Defaults to "./blib/bin", just to have a dummy location during
1314 testing. make install will copy the files in INST_SCRIPT to
1319 defaults to "$(OBJECT)" and is used in the ld command to specify
1320 what files to link/load from (also see dynamic_lib below for how to
1325 The filename of the perllibrary that will be used together with this
1326 extension. Defaults to libperl.a.
1330 An anonymous array of alternative library
1331 specifications to be searched for (in order) until
1332 at least one library is found. E.g.
1334 'LIBS' => ["-lgdbm", "-ldbm -lfoo", "-L/path -ldbm.nfs"]
1336 Mind, that any element of the array
1337 contains a complete set of arguments for the ld
1338 command. So do not specify
1340 'LIBS' => ["-ltcl", "-ltk", "-lX11"]
1342 See ODBM_File/Makefile.PL for an example, where an array is needed. If
1343 you specify a scalar as in
1345 'LIBS' => "-ltcl -ltk -lX11"
1347 MakeMaker will turn it into an array with one element.
1351 'static' or 'dynamic' (default unless usedl=undef in
1352 config.sh). Should only be used to force static linking (also see
1357 Boolean which tells MakeMaker, that it should include the rules to
1358 make a perl. This is handled automatically as a switch by
1359 MakeMaker. The user normally does not need it.
1363 The name of the Makefile to be produced.
1367 Hashref of pod-containing files. MakeMaker will default this to all
1368 EXE_FILES files that include POD directives. The files listed
1369 here will be converted to man pages and installed as was requested
1374 Hashref of .pm and .pod files. MakeMaker will default this to all
1375 .pod and any .pm files that include POD directives. The files listed
1376 here will be converted to man pages and installed as was requested
1381 If it is intended, that a new perl binary be produced, this variable
1382 may hold a name for that binary. Defaults to perl
1386 If the extension links to a library that it builds set this to the
1387 name of the library (see SDBM_File)
1391 Perl module name for this extension (DBD::Oracle). This will default
1392 to the directory name but should be explicitly defined in the
1397 MakeMaker will figure out, if an extension contains linkable code
1398 anywhere down the directory tree, and will set this variable
1399 accordingly, but you can speed it up a very little bit, if you define
1400 this boolean variable yourself.
1404 Defaults to C<@>. By setting it to an empty string you can generate a
1405 Makefile that echos all commands. Mainly used in debugging MakeMaker
1410 Boolean. Attribute to inhibit descending into subdirectories.
1414 List of object files, defaults to '$(BASEEXT)$(OBJ_EXT)', but can be a long
1415 string containing all object files, e.g. "tkpBind.o
1416 tkpButton.o tkpCanvas.o"
1420 Defaults to C<-O>. Set it to C<-g> to turn debugging on. The flag is
1421 passed to subdirectory makes.
1425 Perl binary for tasks that can be done by miniperl
1429 The call to the program that is able to compile perlmain.c. Defaults
1434 Same as above for architecture dependent files
1438 Directory containing the Perl library to use.
1442 Directory containing the Perl source code (use of this should be
1443 avoided, it may be undefined)
1447 Ref to hash of files to be processed as perl programs. MakeMaker
1448 will default to any found *.PL file (except Makefile.PL) being keys
1449 and the basename of the file being the value. E.g.
1451 {'foobar.PL' => 'foobar'}
1453 The *.PL files are expected to produce output to the target files
1458 Hashref of .pm files and *.pl files to be installed. e.g.
1460 {'name_of_file.pm' => '$(INST_LIBDIR)/install_as.pm'}
1462 By default this will include *.pm and *.pl. If a lib directory
1463 exists and is not listed in DIR (above) then any *.pm and *.pl files
1464 it contains will also be included by default. Defining PM in the
1465 Makefile.PL will override PMLIBDIRS.
1469 Ref to array of subdirectories containing library files. Defaults to
1470 [ 'lib', $(BASEEXT) ]. The directories will be scanned and any files
1471 they contain will be installed in the corresponding location in the
1472 library. A libscan() method can be used to alter the behaviour.
1473 Defining PM in the Makefile.PL will override PMLIBDIRS.
1477 Can be used to set the three INSTALL* attributes in one go (except for
1478 probably INSTALLMAN1DIR, if it is not below PREFIX according to
1479 %Config). They will have PREFIX as a common directory node and will
1480 branch from that node into lib/, lib/ARCHNAME or whatever Configure
1481 decided at the build time of your perl (unless you override one of
1486 Hashref: Names of modules that need to be available to run this
1487 extension (e.g. Fcntl for SDBM_File) are the keys of the hash and the
1488 desired version is the value. If the required version number is 0, we
1489 only check if any version is installed already.
1493 Arryref. E.g. [qw(name1 name2)] skip (do not write) sections of the
1494 Makefile. Caution! Do not use the SKIP attribute for the neglectible
1495 speedup. It may seriously damage the resulting Makefile. Only use it,
1496 if you really need it.
1500 Ref to array of typemap file names. Use this when the typemaps are
1501 in some directory other than the current directory or when they are
1502 not named B<typemap>. The last typemap in the list takes
1503 precedence. A typemap in the current directory has highest
1504 precedence, even if it isn't listed in TYPEMAPS. The default system
1505 typemap has lowest precedence.
1509 Your version number for distributing the package. This defaults to
1514 Instead of specifying the VERSION in the Makefile.PL you can let
1515 MakeMaker parse a file to determine the version number. The parsing
1516 routine requires that the file named by VERSION_FROM contains one
1517 single line to compute the version number. The first line in the file
1518 that contains the regular expression
1520 /(\$[\w:]*\bVERSION)\b.*=/
1522 will be evaluated with eval() and the value of the named variable
1523 B<after> the eval() will be assigned to the VERSION attribute of the
1524 MakeMaker object. The following lines will be parsed o.k.:
1527 ( $VERSION ) = '$Revision: 1.201 $ ' =~ /\$Revision:\s+([^\s]+)/;
1528 $FOO::VERSION = '1.10';
1530 but these will fail:
1532 my $VERSION = '1.01';
1533 local $VERSION = '1.02';
1534 local $FOO::VERSION = '1.30';
1536 The file named in VERSION_FROM is added as a dependency to Makefile to
1537 guarantee, that the Makefile contains the correct VERSION macro after
1538 a change of the file.
1542 Hashref of .xs files. MakeMaker will default this. e.g.
1544 {'name_of_file.xs' => 'name_of_file.c'}
1546 The .c files will automatically be included in the list of files
1547 deleted by a make clean.
1551 String of options to pass to xsubpp. This might include C<-C++> or
1552 C<-extern>. Do not include typemaps here; the TYPEMAP parameter exists for
1557 May be set to an empty string, which is identical to C<-prototypes>, or
1558 C<-noprototypes>. See the xsubpp documentation for details. MakeMaker
1559 defaults to the empty string.
1563 Your version number for the .xs file of this package. This defaults
1564 to the value of the VERSION attribute.
1568 =head2 Additional lowercase attributes
1570 can be used to pass parameters to the methods which implement that
1571 part of the Makefile.
1577 {FILES => "*.xyz foo"}
1581 {ANY_TARGET => ANY_DEPENDECY, ...}
1585 {TARFLAGS => 'cvfF', COMPRESS => 'gzip', SUFFIX => 'gz',
1586 SHAR => 'shar -m', DIST_CP => 'ln', ZIP => '/bin/zip',
1587 ZIPFLAGS => '-rl', DIST_DEFAULT => 'private tardist' }
1589 If you specify COMPRESS, then SUFFIX should also be altered, as it is
1590 needed to tell make the target file of the compression. Setting
1591 DIST_CP to ln can be useful, if you need to preserve the timestamps on
1592 your files. DIST_CP can take the values 'cp', which copies the file,
1593 'ln', which links the file, and 'best' which copies symbolic links and
1594 links the rest. Default is 'best'.
1598 {ARMAYBE => 'ar', OTHERLDFLAGS => '...', INST_DYNAMIC_DEP => '...'}
1602 Deprecated as of MakeMaker 5.23. See L<ExtUtils::MM_Unix/pm_to_blib>.
1606 {LINKTYPE => 'static', 'dynamic' or ''}
1608 NB: Extensions that have nothing but *.pm files had to say
1612 with Pre-5.0 MakeMakers. Since version 5.00 of MakeMaker such a line
1613 can be deleted safely. MakeMaker recognizes, when there's nothing to
1618 {ANY_MACRO => ANY_VALUE, ...}
1622 {FILES => '$(INST_ARCHAUTODIR)/*.xyz'}

1634 # Don't delete this cut, MM depends on it!
1636 =head2 Overriding MakeMaker Methods
1638 If you cannot achieve the desired Makefile behaviour by specifying
1639 attributes you may define private subroutines in the Makefile.PL.
1640 Each subroutines returns the text it wishes to have written to
1641 the Makefile. To override a section of the Makefile you can
1644 sub MY::c_o { "new literal text" }
1646 or you can edit the default by saying something like:
1649 my($inherited) = shift->SUPER::c_o(@_);
1650 $inherited =~ s/old text/new text/;
1654 If you running experiments with embedding perl as a library into other
1655 applications, you might find MakeMaker not sufficient. You'd better
1656 have a look at ExtUtils::embed which is a collection of utilities for
1659 If you still need a different solution, try to develop another
1660 subroutine, that fits your needs and submit the diffs to
1661 F<perl5-porters@nicoh.com> or F<comp.lang.perl.misc> as appropriate.
1663 For a complete description of all MakeMaker methods see L<ExtUtils::MM_Unix>.
1665 Here is a simple example of how to add a new target to the generated
1670 $(MYEXTLIB): sdbm/Makefile
1671 cd sdbm && $(MAKE) all
1676 =head2 Hintsfile support
1678 MakeMaker.pm uses the architecture specific information from
1679 Config.pm. In addition it evaluates architecture specific hints files
1680 in a C<hints/> directory. The hints files are expected to be named
1681 like their counterparts in C<PERL_SRC/hints>, but with an C<.pl> file
1682 name extension (eg. C<next_3_2.pl>). They are simply C<eval>ed by
1683 MakeMaker within the WriteMakefile() subroutine, and can be used to
1684 execute commands as well as to include special variables. The rules
1685 which hintsfile is chosen are the same as in Configure.
1687 The hintsfile is eval()ed immediately after the arguments given to
1688 WriteMakefile are stuffed into a hash reference $self but before this
1689 reference becomes blessed. So if you want to do the equivalent to
1690 override or create an attribute you would say something like
1692 $self->{LIBS} = ['-ldbm -lucb -lc'];
1694 =head2 Distribution Support
1696 For authors of extensions MakeMaker provides several Makefile
1697 targets. Most of the support comes from the ExtUtils::Manifest module,
1698 where additional documentation can be found.
1702 =item make distcheck
1704 reports which files are below the build directory but not in the
1705 MANIFEST file and vice versa. (See ExtUtils::Manifest::fullcheck() for
1708 =item make skipcheck
1710 reports which files are skipped due to the entries in the
1711 C<MANIFEST.SKIP> file (See ExtUtils::Manifest::skipcheck() for
1714 =item make distclean
1716 does a realclean first and then the distcheck. Note that this is not
1717 needed to build a new distribution as long as you are sure, that the
1718 MANIFEST file is ok.
1722 rewrites the MANIFEST file, adding all remaining files found (See
1723 ExtUtils::Manifest::mkmanifest() for details)
1727 Copies all the files that are in the MANIFEST file to a newly created
1728 directory with the name C<$(DISTNAME)-$(VERSION)>. If that directory
1729 exists, it will be removed first.
1733 Makes a distdir first, and runs a C<perl Makefile.PL>, a make, and
1734 a make test in that directory.
1738 First does a distdir. Then a command $(PREOP) which defaults to a null
1739 command, followed by $(TOUNIX), which defaults to a null command under
1740 UNIX, and will convert files in distribution directory to UNIX format
1741 otherwise. Next it runs C<tar> on that directory into a tarfile and
1742 deletes the directory. Finishes with a command $(POSTOP) which
1743 defaults to a null command.
1747 Defaults to $(DIST_DEFAULT) which in turn defaults to tardist.
1749 =item make uutardist
1751 Runs a tardist first and uuencodes the tarfile.
1755 First does a distdir. Then a command $(PREOP) which defaults to a null
1756 command. Next it runs C<shar> on that directory into a sharfile and
1757 deletes the intermediate directory again. Finishes with a command
1758 $(POSTOP) which defaults to a null command. Note: For shdist to work
1759 properly a C<shar> program that can handle directories is mandatory.
1763 First does a distdir. Then a command $(PREOP) which defaults to a null
1764 command. Runs C<$(ZIP) $(ZIPFLAGS)> on that directory into a
1765 zipfile. Then deletes that directory. Finishes with a command
1766 $(POSTOP) which defaults to a null command.
1770 Does a $(CI) and a $(RCS_LABEL) on all files in the MANIFEST file.
1774 Customization of the dist targets can be done by specifying a hash
1775 reference to the dist attribute of the WriteMakefile call. The
1776 following parameters are recognized:
1779 COMPRESS ('compress')
1782 TO_UNIX (depends on the system)
1783 RCS_LABEL ('rcs -q -Nv$(VERSION_SYM):')
1793 WriteMakefile( 'dist' => { COMPRESS=>"gzip", SUFFIX=>"gz" })
