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336 most probably outdated.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

984 ExtUtils::MakeMaker - Create a module Makefile
988 use ExtUtils::MakeMaker;
990 WriteMakefile( ATTRIBUTE => VALUE [, ...] );
994 This utility is designed to write a Makefile for an extension module
995 from a Makefile.PL. It is based on the Makefile.SH model provided by
996 Andy Dougherty and the perl5-porters.
998 It splits the task of generating the Makefile into several subroutines
999 that can be individually overridden. Each subroutine returns the text
1000 it wishes to have written to the Makefile.
1002 MakeMaker is object oriented. Each directory below the current
1003 directory that contains a Makefile.PL is treated as a separate
1004 object. This makes it possible to write an unlimited number of
1005 Makefiles with a single invocation of WriteMakefile().
1007 =head2 How To Write A Makefile.PL
1009 See ExtUtils::MakeMaker::Tutorial.
1011 The long answer is the rest of the manpage :-)
1013 =head2 Default Makefile Behaviour
1015 The generated Makefile enables the user of the extension to invoke
1017 perl Makefile.PL # optionally "perl Makefile.PL verbose"
1019 make test # optionally set TEST_VERBOSE=1
1020 make install # See below
1022 The Makefile to be produced may be altered by adding arguments of the
1023 form C<KEY=VALUE>. E.g.
1025 perl Makefile.PL PREFIX=~
1027 Other interesting targets in the generated Makefile are
1029 make config # to check if the Makefile is up-to-date
1030 make clean # delete local temp files (Makefile gets renamed)
1031 make realclean # delete derived files (including ./blib)
1032 make ci # check in all the files in the MANIFEST file
1033 make dist # see below the Distribution Support section
1037 MakeMaker checks for the existence of a file named F<test.pl> in the
1038 current directory and if it exists it execute the script with the
1039 proper set of perl C<-I> options.
1041 MakeMaker also checks for any files matching glob("t/*.t"). It will
1042 execute all matching files in alphabetical order via the
1043 L<Test::Harness> module with the C<-I> switches set correctly.
1045 If you'd like to see the raw output of your tests, set the
1046 C<TEST_VERBOSE> variable to true.
1048 make test TEST_VERBOSE=1
1052 A useful variation of the above is the target C<testdb>. It runs the
1053 test under the Perl debugger (see L<perldebug>). If the file
1054 F<test.pl> exists in the current directory, it is used for the test.
1056 If you want to debug some other testfile, set the C<TEST_FILE> variable
1059 make testdb TEST_FILE=t/mytest.t
1061 By default the debugger is called using C<-d> option to perl. If you
1062 want to specify some other option, set the C<TESTDB_SW> variable:
1064 make testdb TESTDB_SW=-Dx
1068 make alone puts all relevant files into directories that are named by
1069 the macros INST_LIB, INST_ARCHLIB, INST_SCRIPT, INST_MAN1DIR and
1070 INST_MAN3DIR. All these default to something below ./blib if you are
1071 I<not> building below the perl source directory. If you I<are>
1072 building below the perl source, INST_LIB and INST_ARCHLIB default to
1073 ../../lib, and INST_SCRIPT is not defined.
1075 The I<install> target of the generated Makefile copies the files found
1076 below each of the INST_* directories to their INSTALL*
1077 counterparts. Which counterparts are chosen depends on the setting of
1078 INSTALLDIRS according to the following table:
1083 PERLPREFIX SITEPREFIX VENDORPREFIX
1084 INST_ARCHLIB INSTALLARCHLIB INSTALLSITEARCH INSTALLVENDORARCH
1085 INST_LIB INSTALLPRIVLIB INSTALLSITELIB INSTALLVENDORLIB
1086 INST_BIN INSTALLBIN INSTALLSITEBIN INSTALLVENDORBIN
1087 INST_SCRIPT INSTALLSCRIPT INSTALLSCRIPT INSTALLSCRIPT
1088 INST_MAN1DIR INSTALLMAN1DIR INSTALLSITEMAN1DIR INSTALLVENDORMAN1DIR
1089 INST_MAN3DIR INSTALLMAN3DIR INSTALLSITEMAN3DIR INSTALLVENDORMAN3DIR
1091 The INSTALL... macros in turn default to their %Config
1092 ($Config{installprivlib}, $Config{installarchlib}, etc.) counterparts.
1094 You can check the values of these variables on your system with
1098 And to check the sequence in which the library directories are
1099 searched by perl, run
1101 perl -le 'print join $/, @INC'
1103 Sometimes older versions of the module you're installing live in other
1104 directories in @INC. Because Perl loads the first version of a module it
1105 finds, not the newest, you might accidentally get one of these older
1106 versions even after installing a brand new version. To delete I<all other
1107 versions of the module you're installing> (not simply older ones) set the
1110 make install UNINST=1
1113 =head2 PREFIX and LIB attribute
1115 PREFIX and LIB can be used to set several INSTALL* attributes in one
1116 go. The quickest way to install a module in a non-standard place might
1119 perl Makefile.PL PREFIX=~
1121 This will install all files in the module under your home directory,
1122 with man pages and libraries going into an appropriate place (usually
1125 Another way to specify many INSTALL directories with a single
1128 perl Makefile.PL LIB=~/lib
1130 This will install the module's architecture-independent files into
1131 ~/lib, the architecture-dependent files into ~/lib/$archname.
1133 Note, that in both cases the tilde expansion is done by MakeMaker, not
1134 by perl by default, nor by make.
1136 Conflicts between parameters LIB, PREFIX and the various INSTALL*
1137 arguments are resolved so that:
1143 setting LIB overrides any setting of INSTALLPRIVLIB, INSTALLARCHLIB,
1144 INSTALLSITELIB, INSTALLSITEARCH (and they are not affected by PREFIX);
1148 without LIB, setting PREFIX replaces the initial C<$Config{prefix}>
1149 part of those INSTALL* arguments, even if the latter are explicitly
1150 set (but are set to still start with C<$Config{prefix}>).
1154 If the user has superuser privileges, and is not working on AFS or
1155 relatives, then the defaults for INSTALLPRIVLIB, INSTALLARCHLIB,
1156 INSTALLSCRIPT, etc. will be appropriate, and this incantation will be
1164 make install per default writes some documentation of what has been
1165 done into the file C<$(INSTALLARCHLIB)/perllocal.pod>. This feature
1166 can be bypassed by calling make pure_install.
1170 will have to specify the installation directories as these most
1171 probably have changed since perl itself has been installed. They will
1172 have to do this by calling
1174 perl Makefile.PL INSTALLSITELIB=/afs/here/today \
1175 INSTALLSCRIPT=/afs/there/now INSTALLMAN3DIR=/afs/for/manpages
1178 Be careful to repeat this procedure every time you recompile an
1179 extension, unless you are sure the AFS installation directories are
1182 =head2 Static Linking of a new Perl Binary
1184 An extension that is built with the above steps is ready to use on
1185 systems supporting dynamic loading. On systems that do not support
1186 dynamic loading, any newly created extension has to be linked together
1187 with the available resources. MakeMaker supports the linking process
1188 by creating appropriate targets in the Makefile whenever an extension
1189 is built. You can invoke the corresponding section of the makefile with
1193 That produces a new perl binary in the current directory with all
1194 extensions linked in that can be found in INST_ARCHLIB, SITELIBEXP,
1195 and PERL_ARCHLIB. To do that, MakeMaker writes a new Makefile, on
1196 UNIX, this is called Makefile.aperl (may be system dependent). If you
1197 want to force the creation of a new perl, it is recommended, that you
1198 delete this Makefile.aperl, so the directories are searched-through
1199 for linkable libraries again.
1201 The binary can be installed into the directory where perl normally
1202 resides on your machine with
1206 To produce a perl binary with a different name than C<perl>, either say
1208 perl Makefile.PL MAP_TARGET=myperl
1215 make myperl MAP_TARGET=myperl
1216 make inst_perl MAP_TARGET=myperl
1218 In any case you will be prompted with the correct invocation of the
1219 C<inst_perl> target that installs the new binary into INSTALLBIN.
1221 make inst_perl per default writes some documentation of what has been
1222 done into the file C<$(INSTALLARCHLIB)/perllocal.pod>. This
1223 can be bypassed by calling make pure_inst_perl.
1225 Warning: the inst_perl: target will most probably overwrite your
1226 existing perl binary. Use with care!
1228 Sometimes you might want to build a statically linked perl although
1229 your system supports dynamic loading. In this case you may explicitly
1230 set the linktype with the invocation of the Makefile.PL or make:
1232 perl Makefile.PL LINKTYPE=static # recommended
1236 make LINKTYPE=static # works on most systems
1238 =head2 Determination of Perl Library and Installation Locations
1240 MakeMaker needs to know, or to guess, where certain things are
1241 located. Especially INST_LIB and INST_ARCHLIB (where to put the files
1242 during the make(1) run), PERL_LIB and PERL_ARCHLIB (where to read
1243 existing modules from), and PERL_INC (header files and C<libperl*.*>).
1245 Extensions may be built either using the contents of the perl source
1246 directory tree or from the installed perl library. The recommended way
1247 is to build extensions after you have run 'make install' on perl
1248 itself. You can do that in any directory on your hard disk that is not
1249 below the perl source tree. The support for extensions below the ext
1250 directory of the perl distribution is only good for the standard
1251 extensions that come with perl.
1253 If an extension is being built below the C<ext/> directory of the perl
1254 source then MakeMaker will set PERL_SRC automatically (e.g.,
1255 C<../..>). If PERL_SRC is defined and the extension is recognized as
1256 a standard extension, then other variables default to the following:
1259 PERL_LIB = PERL_SRC/lib
1260 PERL_ARCHLIB = PERL_SRC/lib
1262 INST_ARCHLIB = PERL_ARCHLIB
1264 If an extension is being built away from the perl source then MakeMaker
1265 will leave PERL_SRC undefined and default to using the installed copy
1266 of the perl library. The other variables default to the following:
1268 PERL_INC = $archlibexp/CORE
1269 PERL_LIB = $privlibexp
1270 PERL_ARCHLIB = $archlibexp
1271 INST_LIB = ./blib/lib
1272 INST_ARCHLIB = ./blib/arch
1274 If perl has not yet been installed then PERL_SRC can be defined on the
1275 command line as shown in the previous section.
1278 =head2 Which architecture dependent directory?
1280 If you don't want to keep the defaults for the INSTALL* macros,
1281 MakeMaker helps you to minimize the typing needed: the usual
1282 relationship between INSTALLPRIVLIB and INSTALLARCHLIB is determined
1283 by Configure at perl compilation time. MakeMaker supports the user who
1284 sets INSTALLPRIVLIB. If INSTALLPRIVLIB is set, but INSTALLARCHLIB not,
1285 then MakeMaker defaults the latter to be the same subdirectory of
1286 INSTALLPRIVLIB as Configure decided for the counterparts in %Config ,
1287 otherwise it defaults to INSTALLPRIVLIB. The same relationship holds
1288 for INSTALLSITELIB and INSTALLSITEARCH.
1290 MakeMaker gives you much more freedom than needed to configure
1291 internal variables and get different results. It is worth to mention,
1292 that make(1) also lets you configure most of the variables that are
1293 used in the Makefile. But in the majority of situations this will not
1294 be necessary, and should only be done if the author of a package
1295 recommends it (or you know what you're doing).
1297 =head2 Using Attributes and Parameters
1299 The following attributes may be specified as arguments to WriteMakefile()
1300 or as NAME=VALUE pairs on the command line.
1306 One line description of the module. Will be included in PPD file.
1310 Name of the file that contains the package description. MakeMaker looks
1311 for a line in the POD matching /^($package\s-\s)(.*)/. This is typically
1312 the first line in the "=head1 NAME" section. $2 becomes the abstract.
1316 String containing name (and email address) of package author(s). Is used
1317 in PPD (Perl Package Description) files for PPM (Perl Package Manager).
1319 =item BINARY_LOCATION
1321 Used when creating PPD files for binary packages. It can be set to a
1322 full or relative path or URL to the binary archive for a particular
1323 architecture. For example:
1325 perl Makefile.PL BINARY_LOCATION=x86/Agent.tar.gz
1327 builds a PPD package that references a binary of the C<Agent> package,
1328 located in the C<x86> directory relative to the PPD itself.
1332 Ref to array of *.c file names. Initialised from a directory scan
1333 and the values portion of the XS attribute hash. This is not
1334 currently used by MakeMaker but may be handy in Makefile.PLs.
1338 String that will be included in the compiler call command line between
1339 the arguments INC and OPTIMIZE.
1343 Arrayref. E.g. [qw(archname manext)] defines ARCHNAME & MANEXT from
1344 config.sh. MakeMaker will add to CONFIG the following values anyway:
1364 CODE reference. The subroutine should return a hash reference. The
1365 hash may contain further attributes, e.g. {LIBS =E<gt> ...}, that have to
1366 be determined by some evaluation method.
1370 Something like C<"-DHAVE_UNISTD_H">
1374 This is the root directory into which the code will be installed. It
1375 I<prepends itself to the normal prefix>. For example, if your code
1376 would normally go into F</usr/local/lib/perl> you could set DESTDIR=~/tmp/
1377 and installation would go into F<~/tmp/usr/local/lib/perl>.
1379 This is primarily of use for people who repackage Perl modules.
1381 NOTE: Due to the nature of make, it is important that you put the trailing
1382 slash on your DESTDIR. F<~/tmp/> not F<~/tmp>.
1386 Ref to array of subdirectories containing Makefile.PLs e.g. [ 'sdbm'
1391 A safe filename for the package.
1393 Defaults to NAME above but with :: replaced with -.
1395 For example, Foo::Bar becomes Foo-Bar.
1399 Your name for distributing the package with the version number
1400 included. This is used by 'make dist' to name the resulting archive
1403 Defaults to DISTNAME-VERSION.
1405 For example, version 1.04 of Foo::Bar becomes Foo-Bar-1.04.
1407 On some OS's where . has special meaning VERSION_SYM may be used in
1412 Hashref of symbol names for routines to be made available as universal
1413 symbols. Each key/value pair consists of the package name and an
1414 array of routine names in that package. Used only under AIX, OS/2,
1415 VMS and Win32 at present. The routine names supplied will be expanded
1416 in the same way as XSUB names are expanded by the XS() macro.
1419 {"$(NAME)" => ["boot_$(NAME)" ] }
1423 {"RPC" => [qw( boot_rpcb rpcb_gettime getnetconfigent )],
1424 "NetconfigPtr" => [ 'DESTROY'] }
1426 Please see the L<ExtUtils::Mksymlists> documentation for more information
1427 about the DL_FUNCS, DL_VARS and FUNCLIST attributes.
1431 Array of symbol names for variables to be made available as universal symbols.
1432 Used only under AIX, OS/2, VMS and Win32 at present. Defaults to [].
1433 (e.g. [ qw(Foo_version Foo_numstreams Foo_tree ) ])
1437 Array of extension names to exclude when doing a static build. This
1438 is ignored if INCLUDE_EXT is present. Consult INCLUDE_EXT for more
1439 details. (e.g. [ qw( Socket POSIX ) ] )
1441 This attribute may be most useful when specified as a string on the
1442 command line: perl Makefile.PL EXCLUDE_EXT='Socket Safe'
1446 Ref to array of executable files. The files will be copied to the
1447 INST_SCRIPT directory. Make realclean will delete them from there
1450 If your executables start with something like #!perl or
1451 #!/usr/bin/perl MakeMaker will change this to the path of the perl
1452 'Makefile.PL' was invoked with so the programs will be sure to run
1453 properly even if perl is not in /usr/bin/perl.
1455 =item FIRST_MAKEFILE
1457 The name of the Makefile to be produced. This is used for the second
1458 Makefile that will be produced for the MAP_TARGET.
1460 Defaults to 'Makefile' or 'Descrip.MMS' on VMS.
1462 (Note: we couldn't use MAKEFILE because dmake uses this for something
1467 Perl binary able to run this extension, load XS modules, etc...
1471 Like PERLRUN, except it uses FULLPERL.
1473 =item FULLPERLRUNINST
1475 Like PERLRUNINST, except it uses FULLPERL.
1479 This provides an alternate means to specify function names to be
1480 exported from the extension. Its value is a reference to an
1481 array of function names to be exported by the extension. These
1482 names are passed through unaltered to the linker options file.
1486 Ref to array of *.h file names. Similar to C.
1490 This attribute is used to specify names to be imported into the
1491 extension. Takes a hash ref.
1493 It is only used on OS/2 and Win32.
1497 Include file dirs eg: C<"-I/usr/5include -I/path/to/inc">
1501 Array of extension names to be included when doing a static build.
1502 MakeMaker will normally build with all of the installed extensions when
1503 doing a static build, and that is usually the desired behavior. If
1504 INCLUDE_EXT is present then MakeMaker will build only with those extensions
1505 which are explicitly mentioned. (e.g. [ qw( Socket POSIX ) ])
1507 It is not necessary to mention DynaLoader or the current extension when
1508 filling in INCLUDE_EXT. If the INCLUDE_EXT is mentioned but is empty then
1509 only DynaLoader and the current extension will be included in the build.
1511 This attribute may be most useful when specified as a string on the
1512 command line: perl Makefile.PL INCLUDE_EXT='POSIX Socket Devel::Peek'
1514 =item INSTALLARCHLIB
1516 Used by 'make install', which copies files from INST_ARCHLIB to this
1517 directory if INSTALLDIRS is set to perl.
1521 Directory to install binary files (e.g. tkperl) into if
1526 Determines which of the sets of installation directories to choose:
1527 perl, site or vendor. Defaults to site.
1529 =item INSTALLMAN1DIR
1531 =item INSTALLMAN3DIR
1533 These directories get the man pages at 'make install' time if
1534 INSTALLDIRS=perl. Defaults to $Config{installman*dir}.
1536 If set to 'none', no man pages will be installed.
1538 =item INSTALLPRIVLIB
1540 Used by 'make install', which copies files from INST_LIB to this
1541 directory if INSTALLDIRS is set to perl.
1543 Defaults to $Config{installprivlib}.
1547 Used by 'make install' which copies files from INST_SCRIPT to this
1550 =item INSTALLSITEARCH
1552 Used by 'make install', which copies files from INST_ARCHLIB to this
1553 directory if INSTALLDIRS is set to site (default).
1555 =item INSTALLSITEBIN
1557 Used by 'make install', which copies files from INST_BIN to this
1558 directory if INSTALLDIRS is set to site (default).
1560 =item INSTALLSITELIB
1562 Used by 'make install', which copies files from INST_LIB to this
1563 directory if INSTALLDIRS is set to site (default).
1565 =item INSTALLSITEMAN1DIR
1567 =item INSTALLSITEMAN3DIR
1569 These directories get the man pages at 'make install' time if
1570 INSTALLDIRS=site (default). Defaults to
1571 $(SITEPREFIX)/man/man$(MAN*EXT).
1573 If set to 'none', no man pages will be installed.
1575 =item INSTALLVENDORARCH
1577 Used by 'make install', which copies files from INST_ARCHLIB to this
1578 directory if INSTALLDIRS is set to vendor.
1580 =item INSTALLVENDORBIN
1582 Used by 'make install', which copies files from INST_BIN to this
1583 directory if INSTALLDIRS is set to vendor.
1585 =item INSTALLVENDORLIB
1587 Used by 'make install', which copies files from INST_LIB to this
1588 directory if INSTALLDIRS is set to vendor.
1590 =item INSTALLVENDORMAN1DIR
1592 =item INSTALLVENDORMAN3DIR
1594 These directories get the man pages at 'make install' time if
1595 INSTALLDIRS=vendor. Defaults to $(VENDORPREFIX)/man/man$(MAN*EXT).
1597 If set to 'none', no man pages will be installed.
1601 Same as INST_LIB for architecture dependent files.
1605 Directory to put real binary files during 'make'. These will be copied
1606 to INSTALLBIN during 'make install'
1610 Directory where we put library files of this extension while building
1615 Directory to hold the man pages at 'make' time
1619 Directory to hold the man pages at 'make' time
1623 Directory, where executable files should be installed during
1624 'make'. Defaults to "./blib/script", just to have a dummy location during
1625 testing. make install will copy the files in INST_SCRIPT to
1630 Program to be used to link libraries for dynamic loading.
1632 Defaults to $Config{ld}.
1636 Any special flags that might need to be passed to ld to create a
1637 shared library suitable for dynamic loading. It is up to the makefile
1638 to use it. (See L<Config/lddlflags>)
1640 Defaults to $Config{lddlflags}.
1644 Defaults to "$(OBJECT)" and is used in the ld command to specify
1645 what files to link/load from (also see dynamic_lib below for how to
1650 LIB should only be set at C<perl Makefile.PL> time but is allowed as a
1651 MakeMaker argument. It has the effect of setting both INSTALLPRIVLIB
1652 and INSTALLSITELIB to that value regardless any explicit setting of
1653 those arguments (or of PREFIX). INSTALLARCHLIB and INSTALLSITEARCH
1654 are set to the corresponding architecture subdirectory.
1658 The filename of the perllibrary that will be used together with this
1659 extension. Defaults to libperl.a.
1663 An anonymous array of alternative library
1664 specifications to be searched for (in order) until
1665 at least one library is found. E.g.
1667 'LIBS' => ["-lgdbm", "-ldbm -lfoo", "-L/path -ldbm.nfs"]
1669 Mind, that any element of the array
1670 contains a complete set of arguments for the ld
1671 command. So do not specify
1673 'LIBS' => ["-ltcl", "-ltk", "-lX11"]
1675 See ODBM_File/Makefile.PL for an example, where an array is needed. If
1676 you specify a scalar as in
1678 'LIBS' => "-ltcl -ltk -lX11"
1680 MakeMaker will turn it into an array with one element.
1684 'static' or 'dynamic' (default unless usedl=undef in
1685 config.sh). Should only be used to force static linking (also see
1690 Boolean which tells MakeMaker, that it should include the rules to
1691 make a perl. This is handled automatically as a switch by
1692 MakeMaker. The user normally does not need it.
1696 When 'make clean' or similar is run, the $(FIRST_MAKEFILE) will be
1697 backed up at this location.
1699 Defaults to $(FIRST_MAKEFILE).old or $(FIRST_MAKEFILE)_old on VMS.
1703 Hashref of pod-containing files. MakeMaker will default this to all
1704 EXE_FILES files that include POD directives. The files listed
1705 here will be converted to man pages and installed as was requested
1710 Hashref that assigns to *.pm and *.pod files the files into which the
1711 manpages are to be written. MakeMaker parses all *.pod and *.pm files
1712 for POD directives. Files that contain POD will be the default keys of
1713 the MAN3PODS hashref. These will then be converted to man pages during
1714 C<make> and will be installed during C<make install>.
1718 If it is intended, that a new perl binary be produced, this variable
1719 may hold a name for that binary. Defaults to perl
1723 If the extension links to a library that it builds set this to the
1724 name of the library (see SDBM_File)
1728 Perl module name for this extension (DBD::Oracle). This will default
1729 to the directory name but should be explicitly defined in the
1734 MakeMaker will figure out if an extension contains linkable code
1735 anywhere down the directory tree, and will set this variable
1736 accordingly, but you can speed it up a very little bit if you define
1737 this boolean variable yourself.
1741 Command so make does not print the literal commands its running.
1743 By setting it to an empty string you can generate a Makefile that
1744 prints all commands. Mainly used in debugging MakeMaker itself.
1750 Boolean. Attribute to inhibit descending into subdirectories.
1754 When true, suppresses the generation and addition to the MANIFEST of
1755 the META.yml module meta-data file during 'make distdir'.
1761 In general, any generated Makefile checks for the current version of
1762 MakeMaker and the version the Makefile was built under. If NO_VC is
1763 set, the version check is neglected. Do not write this into your
1764 Makefile.PL, use it interactively instead.
1768 List of object files, defaults to '$(BASEEXT)$(OBJ_EXT)', but can be a long
1769 string containing all object files, e.g. "tkpBind.o
1770 tkpButton.o tkpCanvas.o"
1772 (Where BASEEXT is the last component of NAME, and OBJ_EXT is $Config{obj_ext}.)
1776 Defaults to C<-O>. Set it to C<-g> to turn debugging on. The flag is
1777 passed to subdirectory makes.
1781 Perl binary for tasks that can be done by miniperl
1785 Set only when MakeMaker is building the extensions of the Perl core
1790 The call to the program that is able to compile perlmain.c. Defaults
1795 Same as for PERL_LIB, but for architecture dependent files.
1797 Used only when MakeMaker is building the extensions of the Perl core
1798 distribution (because normally $(PERL_ARCHLIB) is automatically in @INC,
1799 and adding it would get in the way of PERL5LIB).
1803 Directory containing the Perl library to use.
1805 Used only when MakeMaker is building the extensions of the Perl core
1806 distribution (because normally $(PERL_LIB) is automatically in @INC,
1807 and adding it would get in the way of PERL5LIB).
1809 =item PERL_MALLOC_OK
1811 defaults to 0. Should be set to TRUE if the extension can work with
1812 the memory allocation routines substituted by the Perl malloc() subsystem.
1813 This should be applicable to most extensions with exceptions of those
1819 with bugs in memory allocations which are caught by Perl's malloc();
1823 which interact with the memory allocator in other ways than via
1824 malloc(), realloc(), free(), calloc(), sbrk() and brk();
1828 which rely on special alignment which is not provided by Perl's malloc().
1832 B<NOTE.> Negligence to set this flag in I<any one> of loaded extension
1833 nullifies many advantages of Perl's malloc(), such as better usage of
1834 system resources, error detection, memory usage reporting, catchable failure
1835 of memory allocations, etc.
1839 Directory under which core modules are to be installed.
1841 Defaults to $Config{installprefixexp} falling back to
1842 $Config{installprefix}, $Config{prefixexp} or $Config{prefix} should
1843 $Config{installprefixexp} not exist.
1845 Overridden by PREFIX.
1849 Use this instead of $(PERL) when you wish to run perl. It will set up
1850 extra necessary flags for you.
1854 Use this instead of $(PERL) when you wish to run perl to work with
1855 modules. It will add things like -I$(INST_ARCH) and other necessary
1856 flags so perl can see the modules you're about to install.
1860 Directory containing the Perl source code (use of this should be
1861 avoided, it may be undefined)
1865 Desired permission for read/writable files. Defaults to C<644>.
1866 See also L<MM_Unix/perm_rw>.
1870 Desired permission for executable files. Defaults to C<755>.
1871 See also L<MM_Unix/perm_rwx>.
1875 MakeMaker can run programs to generate files for you at build time.
1876 By default any file named *.PL (except Makefile.PL and Build.PL) in
1877 the top level directory will be assumed to be a Perl program and run
1878 passing its own basename in as an argument. For example...
1882 This behavior can be overridden by supplying your own set of files to
1883 search. PL_FILES accepts a hash ref, the key being the file to run
1884 and the value is passed in as the first argument when the PL file is run.
1886 PL_FILES => {'bin/foobar.PL' => 'bin/foobar'}
1888 Would run bin/foobar.PL like this:
1890 perl bin/foobar.PL bin/foobar
1892 If multiple files from one program are desired an array ref can be used.
1894 PL_FILES => {'bin/foobar.PL' => [qw(bin/foobar1 bin/foobar2)]}
1896 In this case the program will be run multiple times using each target file.
1898 perl bin/foobar.PL bin/foobar1
1899 perl bin/foobar.PL bin/foobar2
1904 Hashref of .pm files and *.pl files to be installed. e.g.
1906 {'name_of_file.pm' => '$(INST_LIBDIR)/install_as.pm'}
1908 By default this will include *.pm and *.pl and the files found in
1909 the PMLIBDIRS directories. Defining PM in the
1910 Makefile.PL will override PMLIBDIRS.
1914 Ref to array of subdirectories containing library files. Defaults to
1915 [ 'lib', $(BASEEXT) ]. The directories will be scanned and I<any> files
1916 they contain will be installed in the corresponding location in the
1917 library. A libscan() method can be used to alter the behaviour.
1918 Defining PM in the Makefile.PL will override PMLIBDIRS.
1920 (Where BASEEXT is the last component of NAME.)
1924 A filter program, in the traditional Unix sense (input from stdin, output
1925 to stdout) that is passed on each .pm file during the build (in the
1926 pm_to_blib() phase). It is empty by default, meaning no filtering is done.
1928 Great care is necessary when defining the command if quoting needs to be
1929 done. For instance, you would need to say:
1931 {'PM_FILTER' => 'grep -v \\"^\\#\\"'}
1933 to remove all the leading coments on the fly during the build. The
1934 extra \\ are necessary, unfortunately, because this variable is interpolated
1935 within the context of a Perl program built on the command line, and double
1936 quotes are what is used with the -e switch to build that command line. The
1937 # is escaped for the Makefile, since what is going to be generated will then
1940 PM_FILTER = grep -v \"^\#\"
1942 Without the \\ before the #, we'd have the start of a Makefile comment,
1943 and the macro would be incorrectly defined.
1947 Release 5.005 grandfathered old global symbol names by providing preprocessor
1948 macros for extension source compatibility. As of release 5.6, these
1949 preprocessor definitions are not available by default. The POLLUTE flag
1950 specifies that the old names should still be defined:
1952 perl Makefile.PL POLLUTE=1
1954 Please inform the module author if this is necessary to successfully install
1955 a module under 5.6 or later.
1957 =item PPM_INSTALL_EXEC
1959 Name of the executable used to run C<PPM_INSTALL_SCRIPT> below. (e.g. perl)
1961 =item PPM_INSTALL_SCRIPT
1963 Name of the script that gets executed by the Perl Package Manager after
1964 the installation of a package.
1968 This overrides all the default install locations. Man pages,
1969 libraries, scripts, etc... MakeMaker will try to make an educated
1970 guess about where to place things under the new PREFIX based on your
1971 Config defaults. Failing that, it will fall back to a structure
1972 which should be sensible for your platform.
1974 If you specify LIB or any INSTALL* variables they will not be effected
1979 Bool. If this parameter is true, failing to have the required modules
1980 (or the right versions thereof) will be fatal. perl Makefile.PL will die
1981 with the proper message.
1983 Note: see L<Test::Harness> for a shortcut for stopping tests early if
1984 you are missing dependencies.
1986 Do I<not> use this parameter for simple requirements, which could be resolved
1987 at a later time, e.g. after an unsuccessful B<make test> of your module.
1989 It is I<extremely> rare to have to use C<PREREQ_FATAL> at all!
1993 Hashref: Names of modules that need to be available to run this
1994 extension (e.g. Fcntl for SDBM_File) are the keys of the hash and the
1995 desired version is the value. If the required version number is 0, we
1996 only check if any version is installed already.
2000 Bool. If this parameter is true, the prerequisites will be printed to
2001 stdout and MakeMaker will exit. The output format is an evalable hash
2012 RedHatism for C<PREREQ_PRINT>. The output format is different, though:
2014 perl(A::B)>=Vers1 perl(C::D)>=Vers2 ...
2018 Like PERLPREFIX, but only for the site install locations.
2020 Defaults to $Config{siteprefixexp}. Perls prior to 5.6.0 didn't have
2021 an explicit siteprefix in the Config. In those cases
2022 $Config{installprefix} will be used.
2024 Overridable by PREFIX
2028 When true, perform the generation and addition to the MANIFEST of the
2029 SIGNATURE file in the distdir during 'make distdir', via 'cpansign
2032 Note that you need to install the Module::Signature module to
2033 perform this operation.
2039 Arrayref. E.g. [qw(name1 name2)] skip (do not write) sections of the
2040 Makefile. Caution! Do not use the SKIP attribute for the negligible
2041 speedup. It may seriously damage the resulting Makefile. Only use it
2042 if you really need it.
2046 Ref to array of typemap file names. Use this when the typemaps are
2047 in some directory other than the current directory or when they are
2048 not named B<typemap>. The last typemap in the list takes
2049 precedence. A typemap in the current directory has highest
2050 precedence, even if it isn't listed in TYPEMAPS. The default system
2051 typemap has lowest precedence.
2055 Like PERLPREFIX, but only for the vendor install locations.
2057 Defaults to $Config{vendorprefixexp}.
2059 Overridable by PREFIX
2063 If true, make install will be verbose
2067 Your version number for distributing the package. This defaults to
2072 Instead of specifying the VERSION in the Makefile.PL you can let
2073 MakeMaker parse a file to determine the version number. The parsing
2074 routine requires that the file named by VERSION_FROM contains one
2075 single line to compute the version number. The first line in the file
2076 that contains the regular expression
2078 /([\$*])(([\w\:\']*)\bVERSION)\b.*\=/
2080 will be evaluated with eval() and the value of the named variable
2081 B<after> the eval() will be assigned to the VERSION attribute of the
2082 MakeMaker object. The following lines will be parsed o.k.:
2086 $VERSION = sprintf "%d.%03d", q$Revision: 4409 $ =~ /(\d+)/g;
2087 $FOO::VERSION = '1.10';
2088 *FOO::VERSION = \'1.11';
2089 our $VERSION = 1.2.3; # new for perl5.6.0
2091 but these will fail:
2093 my $VERSION = '1.01';
2094 local $VERSION = '1.02';
2095 local $FOO::VERSION = '1.30';
2097 (Putting C<my> or C<local> on the preceding line will work o.k.)
2099 The file named in VERSION_FROM is not added as a dependency to
2100 Makefile. This is not really correct, but it would be a major pain
2101 during development to have to rewrite the Makefile for any smallish
2102 change in that file. If you want to make sure that the Makefile
2103 contains the correct VERSION macro after any change of the file, you
2104 would have to do something like
2106 depend => { Makefile => '$(VERSION_FROM)' }
2108 See attribute C<depend> below.
2112 A sanitized VERSION with . replaced by _. For places where . has
2113 special meaning (some filesystems, RCS labels, etc...)
2117 Hashref of .xs files. MakeMaker will default this. e.g.
2119 {'name_of_file.xs' => 'name_of_file.c'}
2121 The .c files will automatically be included in the list of files
2122 deleted by a make clean.
2126 String of options to pass to xsubpp. This might include C<-C++> or
2127 C<-extern>. Do not include typemaps here; the TYPEMAP parameter exists for
2132 May be set to an empty string, which is identical to C<-prototypes>, or
2133 C<-noprototypes>. See the xsubpp documentation for details. MakeMaker
2134 defaults to the empty string.
2138 Your version number for the .xs file of this package. This defaults
2139 to the value of the VERSION attribute.
2143 =head2 Additional lowercase attributes
2145 can be used to pass parameters to the methods which implement that
2146 part of the Makefile. Parameters are specified as a hash ref but are
2147 passed to the method as a hash.
2153 {FILES => "*.xyz foo"}
2157 {ANY_TARGET => ANY_DEPENDECY, ...}
2159 (ANY_TARGET must not be given a double-colon rule by MakeMaker.)
2163 {TARFLAGS => 'cvfF', COMPRESS => 'gzip', SUFFIX => '.gz',
2164 SHAR => 'shar -m', DIST_CP => 'ln', ZIP => '/bin/zip',
2165 ZIPFLAGS => '-rl', DIST_DEFAULT => 'private tardist' }
2167 If you specify COMPRESS, then SUFFIX should also be altered, as it is
2168 needed to tell make the target file of the compression. Setting
2169 DIST_CP to ln can be useful, if you need to preserve the timestamps on
2170 your files. DIST_CP can take the values 'cp', which copies the file,
2171 'ln', which links the file, and 'best' which copies symbolic links and
2172 links the rest. Default is 'best'.
2176 {ARMAYBE => 'ar', OTHERLDFLAGS => '...', INST_DYNAMIC_DEP => '...'}
2180 {LINKTYPE => 'static', 'dynamic' or ''}
2182 NB: Extensions that have nothing but *.pm files had to say
2186 with Pre-5.0 MakeMakers. Since version 5.00 of MakeMaker such a line
2187 can be deleted safely. MakeMaker recognizes when there's nothing to
2192 {ANY_MACRO => ANY_VALUE, ...}
2196 Anything put here will be passed to MY::postamble() if you have one.
2200 {FILES => '$(INST_ARCHAUTODIR)/*.xyz'}
2206 =item tool_autosplit
2212 =head2 Overriding MakeMaker Methods
2214 If you cannot achieve the desired Makefile behaviour by specifying
2215 attributes you may define private subroutines in the Makefile.PL.
2216 Each subroutine returns the text it wishes to have written to
2217 the Makefile. To override a section of the Makefile you can
2220 sub MY::c_o { "new literal text" }
2222 or you can edit the default by saying something like:
2224 package MY; # so that "SUPER" works right
2226 my $inherited = shift->SUPER::c_o(@_);
2227 $inherited =~ s/old text/new text/;
2231 If you are running experiments with embedding perl as a library into
2232 other applications, you might find MakeMaker is not sufficient. You'd
2233 better have a look at ExtUtils::Embed which is a collection of utilities
2236 If you still need a different solution, try to develop another
2237 subroutine that fits your needs and submit the diffs to
2238 C<makemaker@perl.org>
2240 For a complete description of all MakeMaker methods see
2241 L<ExtUtils::MM_Unix>.
2243 Here is a simple example of how to add a new target to the generated
2247 return <<'MAKE_FRAG';
2248 $(MYEXTLIB): sdbm/Makefile
2249 cd sdbm && $(MAKE) all
2254 =head2 The End Of Cargo Cult Programming
2256 WriteMakefile() now does some basic sanity checks on its parameters to
2257 protect against typos and malformatted values. This means some things
2258 which happened to work in the past will now throw warnings and
2259 possibly produce internal errors.
2261 Some of the most common mistakes:
2265 =item C<< MAN3PODS => ' ' >>
2267 This is commonly used to supress the creation of man pages. MAN3PODS
2268 takes a hash ref not a string, but the above worked by accident in old
2269 versions of MakeMaker.
2271 The correct code is C<< MAN3PODS => { } >>.
2276 =head2 Hintsfile support
2278 MakeMaker.pm uses the architecture specific information from
2279 Config.pm. In addition it evaluates architecture specific hints files
2280 in a C<hints/> directory. The hints files are expected to be named
2281 like their counterparts in C<PERL_SRC/hints>, but with an C<.pl> file
2282 name extension (eg. C<next_3_2.pl>). They are simply C<eval>ed by
2283 MakeMaker within the WriteMakefile() subroutine, and can be used to
2284 execute commands as well as to include special variables. The rules
2285 which hintsfile is chosen are the same as in Configure.
2287 The hintsfile is eval()ed immediately after the arguments given to
2288 WriteMakefile are stuffed into a hash reference $self but before this
2289 reference becomes blessed. So if you want to do the equivalent to
2290 override or create an attribute you would say something like
2292 $self->{LIBS} = ['-ldbm -lucb -lc'];
2294 =head2 Distribution Support
2296 For authors of extensions MakeMaker provides several Makefile
2297 targets. Most of the support comes from the ExtUtils::Manifest module,
2298 where additional documentation can be found.
2302 =item make distcheck
2304 reports which files are below the build directory but not in the
2305 MANIFEST file and vice versa. (See ExtUtils::Manifest::fullcheck() for
2308 =item make skipcheck
2310 reports which files are skipped due to the entries in the
2311 C<MANIFEST.SKIP> file (See ExtUtils::Manifest::skipcheck() for
2314 =item make distclean
2316 does a realclean first and then the distcheck. Note that this is not
2317 needed to build a new distribution as long as you are sure that the
2318 MANIFEST file is ok.
2322 rewrites the MANIFEST file, adding all remaining files found (See
2323 ExtUtils::Manifest::mkmanifest() for details)
2327 Copies all the files that are in the MANIFEST file to a newly created
2328 directory with the name C<$(DISTNAME)-$(VERSION)>. If that directory
2329 exists, it will be removed first.
2331 Additionally, it will create a META.yml module meta-data file in the
2332 distdir and add this to the distdir's MANFIEST. You can shut this
2333 behavior off with the NO_META flag.
2337 Makes a distdir first, and runs a C<perl Makefile.PL>, a make, and
2338 a make test in that directory.
2342 First does a distdir. Then a command $(PREOP) which defaults to a null
2343 command, followed by $(TOUNIX), which defaults to a null command under
2344 UNIX, and will convert files in distribution directory to UNIX format
2345 otherwise. Next it runs C<tar> on that directory into a tarfile and
2346 deletes the directory. Finishes with a command $(POSTOP) which
2347 defaults to a null command.
2351 Defaults to $(DIST_DEFAULT) which in turn defaults to tardist.
2353 =item make uutardist
2355 Runs a tardist first and uuencodes the tarfile.
2359 First does a distdir. Then a command $(PREOP) which defaults to a null
2360 command. Next it runs C<shar> on that directory into a sharfile and
2361 deletes the intermediate directory again. Finishes with a command
2362 $(POSTOP) which defaults to a null command. Note: For shdist to work
2363 properly a C<shar> program that can handle directories is mandatory.
2367 First does a distdir. Then a command $(PREOP) which defaults to a null
2368 command. Runs C<$(ZIP) $(ZIPFLAGS)> on that directory into a
2369 zipfile. Then deletes that directory. Finishes with a command
2370 $(POSTOP) which defaults to a null command.
2374 Does a $(CI) and a $(RCS_LABEL) on all files in the MANIFEST file.
2378 Customization of the dist targets can be done by specifying a hash
2379 reference to the dist attribute of the WriteMakefile call. The
2380 following parameters are recognized:
2383 COMPRESS ('gzip --best')
2386 TO_UNIX (depends on the system)
2387 RCS_LABEL ('rcs -q -Nv$(VERSION_SYM):')
2397 WriteMakefile( 'dist' => { COMPRESS=>"bzip2", SUFFIX=>".bz2" })
2400 =head2 Module Meta-Data
2402 Long plaguing users of MakeMaker based modules has been the problem of
2403 getting basic information about the module out of the sources
2404 I<without> running the F<Makefile.PL> and doing a bunch of messy
2405 heuristics on the resulting F<Makefile>. To this end a simple module
2406 meta-data file has been introduced, F<META.yml>.
2408 F<META.yml> is a YAML document (see http://www.yaml.org) containing
2409 basic information about the module (name, version, prerequisites...)
2410 in an easy to read format. The format is developed and defined by the
2411 Module::Build developers (see
2412 http://module-build.sourceforge.net/META-spec.html)
2414 MakeMaker will automatically generate a F<META.yml> file for you and
2415 add it to your F<MANIFEST> as part of the 'distdir' target (and thus
2416 the 'dist' target). This is intended to seamlessly and rapidly
2417 populate CPAN with module meta-data. If you wish to shut this feature
2418 off, set the C<NO_META> C<WriteMakefile()> flag to true.
2421 =head2 Disabling an extension
2423 If some events detected in F<Makefile.PL> imply that there is no way
2424 to create the Module, but this is a normal state of things, then you
2425 can create a F<Makefile> which does nothing, but succeeds on all the
2426 "usual" build targets. To do so, use
2428 ExtUtils::MakeMaker::WriteEmptyMakefile();
2430 instead of WriteMakefile().
2432 This may be useful if other modules expect this module to be I<built>
2433 OK, as opposed to I<work> OK (say, this system-dependent module builds
2434 in a subdirectory of some other distribution, or is listed as a
2435 dependency in a CPAN::Bundle, but the functionality is supported by
2436 different means on the current architecture).
2438 =head2 Other Handy Functions
2444 my $value = prompt($message);
2445 my $value = prompt($message, $default);
2447 The C<prompt()> function provides an easy way to request user input
2448 used to write a makefile. It displays the $message as a prompt for
2449 input. If a $default is provided it will be used as a default. The
2450 function returns the $value selected by the user.
2452 If C<prompt()> detects that it is not running interactively and there
2453 is nothing on STDIN or if the PERL_MM_USE_DEFAULT environment variable
2454 is set to true, the $default will be used without prompting. This
