It is based on the Makefile.SH model provided by Andy Dougherty and the perl5-porters. It splits the task of generating the Makefile into several subroutines that can be individually overridden. Each subroutine returns the text it wishes to have written to the Makefile. As there are various Make programs with incompatible syntax, which use operating system shells, again with incompatible syntax, it is important for users of this module to know which flavour of Make a Makefile has been written for so they'll use the correct one and won't have to face the possibly bewildering errors resulting from using the wrong one. On POSIX systems, that program will likely be GNU Make; on Microsoft Windows, it will be either Microsoft NMake, DMake or GNU Make. See the section on the L parameter for details. ExtUtils::MakeMaker (EUMM) is object oriented. Each directory below the current directory that contains a Makefile.PL is treated as a separate object. This makes it possible to write an unlimited number of Makefiles with a single invocation of WriteMakefile(). All inputs to WriteMakefile are Unicode characters, not just octets. EUMM seeks to handle all of these correctly. It is currently still not possible to portably use Unicode characters in module names, because this requires Perl to handle Unicode filenames, which is not yet the case on Windows. =head2 How To Write A Makefile.PL See L. The long answer is the rest of the manpage :-) =head2 Default Makefile Behaviour The generated Makefile enables the user of the extension to invoke perl Makefile.PL # optionally "perl Makefile.PL verbose" make make test # optionally set TEST_VERBOSE=1 make install # See below The Makefile to be produced may be altered by adding arguments of the form C. E.g. perl Makefile.PL INSTALL_BASE=~ Other interesting targets in the generated Makefile are make config # to check if the Makefile is up-to-date make clean # delete local temp files (Makefile gets renamed) make realclean # delete derived files (including ./blib) make ci # check in all the files in the MANIFEST file make dist # see below the Distribution Support section =head2 make test MakeMaker checks for the existence of a file named F in the current directory, and if it exists it executes the script with the proper set of perl C<-I> options. MakeMaker also checks for any files matching glob("t/*.t"). It will execute all matching files in alphabetical order via the L module with the C<-I> switches set correctly. You can also organize your tests within subdirectories in the F directory. To do so, use the F directive in your I. For example, if you had tests in: t/foo t/foo/bar You could tell make to run tests in both of those directories with the following directives: test => {TESTS => 't/*/*.t t/*/*/*.t'} test => {TESTS => 't/foo/*.t t/foo/bar/*.t'} The first will run all test files in all first-level subdirectories and all subdirectories they contain. The second will run tests in only the F and F. If you'd like to see the raw output of your tests, set the C variable to true. make test TEST_VERBOSE=1 If you want to run particular test files, set the C variable. It is possible to use globbing with this mechanism. make test TEST_FILES='t/foobar.t t/dagobah*.t' Windows users who are using C should note that due to a bug in C, when specifying C you must use back-slashes instead of forward-slashes. nmake test TEST_FILES='t\foobar.t t\dagobah*.t' =head2 make testdb A useful variation of the above is the target C. It runs the test under the Perl debugger (see L). If the file F exists in the current directory, it is used for the test. If you want to debug some other testfile, set the C variable thusly: make testdb TEST_FILE=t/mytest.t By default the debugger is called using C<-d> option to perl. If you want to specify some other option, set the C variable: make testdb TESTDB_SW=-Dx =head2 make install make alone puts all relevant files into directories that are named by the macros INST_LIB, INST_ARCHLIB, INST_SCRIPT, INST_MAN1DIR and INST_MAN3DIR. All these default to something below ./blib if you are I building below the perl source directory. If you I building below the perl source, INST_LIB and INST_ARCHLIB default to ../../lib, and INST_SCRIPT is not defined. The I target of the generated Makefile copies the files found below each of the INST_* directories to their INSTALL* counterparts. Which counterparts are chosen depends on the setting of INSTALLDIRS according to the following table: INSTALLDIRS set to perl site vendor PERLPREFIX SITEPREFIX VENDORPREFIX INST_ARCHLIB INSTALLARCHLIB INSTALLSITEARCH INSTALLVENDORARCH INST_LIB INSTALLPRIVLIB INSTALLSITELIB INSTALLVENDORLIB INST_BIN INSTALLBIN INSTALLSITEBIN INSTALLVENDORBIN INST_SCRIPT INSTALLSCRIPT INSTALLSITESCRIPT INSTALLVENDORSCRIPT INST_MAN1DIR INSTALLMAN1DIR INSTALLSITEMAN1DIR INSTALLVENDORMAN1DIR INST_MAN3DIR INSTALLMAN3DIR INSTALLSITEMAN3DIR INSTALLVENDORMAN3DIR The INSTALL... macros in turn default to their %Config ($Config{installprivlib}, $Config{installarchlib}, etc.) counterparts. You can check the values of these variables on your system with perl '-V:install.*' And to check the sequence in which the library directories are searched by perl, run perl -le 'print join $/, @INC' Sometimes older versions of the module you're installing live in other directories in @INC. Because Perl loads the first version of a module it finds, not the newest, you might accidentally get one of these older versions even after installing a brand new version. To delete I (not simply older ones) set the C variable. make install UNINST=1 =head2 INSTALL_BASE INSTALL_BASE can be passed into Makefile.PL to change where your module will be installed. INSTALL_BASE is more like what everyone else calls "prefix" than PREFIX is. To have everything installed in your home directory, do the following. # Unix users, INSTALL_BASE=~ works fine perl Makefile.PL INSTALL_BASE=/path/to/your/home/dir Like PREFIX, it sets several INSTALL* attributes at once. Unlike PREFIX it is easy to predict where the module will end up. The installation pattern looks like this: INSTALLARCHLIB INSTALL_BASE/lib/perl5/$Config{archname} INSTALLPRIVLIB INSTALL_BASE/lib/perl5 INSTALLBIN INSTALL_BASE/bin INSTALLSCRIPT INSTALL_BASE/bin INSTALLMAN1DIR INSTALL_BASE/man/man1 INSTALLMAN3DIR INSTALL_BASE/man/man3 INSTALL_BASE in MakeMaker and C<--install_base> in Module::Build (as of 0.28) install to the same location. If you want MakeMaker and Module::Build to install to the same location simply set INSTALL_BASE and C<--install_base> to the same location. INSTALL_BASE was added in 6.31. =head2 PREFIX and LIB attribute PREFIX and LIB can be used to set several INSTALL* attributes in one go. Here's an example for installing into your home directory. # Unix users, PREFIX=~ works fine perl Makefile.PL PREFIX=/path/to/your/home/dir This will install all files in the module under your home directory, with man pages and libraries going into an appropriate place (usually ~/man and ~/lib). How the exact location is determined is complicated and depends on how your Perl was configured. INSTALL_BASE works more like what other build systems call "prefix" than PREFIX and we recommend you use that instead. Another way to specify many INSTALL directories with a single parameter is LIB. perl Makefile.PL LIB=~/lib This will install the module's architecture-independent files into ~/lib, the architecture-dependent files into ~/lib/$archname. Note, that in both cases the tilde expansion is done by MakeMaker, not by perl by default, nor by make. Conflicts between parameters LIB, PREFIX and the various INSTALL* arguments are resolved so that: =over 4 =item * setting LIB overrides any setting of INSTALLPRIVLIB, INSTALLARCHLIB, INSTALLSITELIB, INSTALLSITEARCH (and they are not affected by PREFIX); =item * without LIB, setting PREFIX replaces the initial C<$Config{prefix}> part of those INSTALL* arguments, even if the latter are explicitly set (but are set to still start with C<$Config{prefix}>). =back If the user has superuser privileges, and is not working on AFS or relatives, then the defaults for INSTALLPRIVLIB, INSTALLARCHLIB, INSTALLSCRIPT, etc. will be appropriate, and this incantation will be the best: perl Makefile.PL; make; make test make install make install by default writes some documentation of what has been done into the file C<$(INSTALLARCHLIB)/perllocal.pod>. This feature can be bypassed by calling make pure_install. =head2 AFS users will have to specify the installation directories as these most probably have changed since perl itself has been installed. They will have to do this by calling perl Makefile.PL INSTALLSITELIB=/afs/here/today \ INSTALLSCRIPT=/afs/there/now INSTALLMAN3DIR=/afs/for/manpages make Be careful to repeat this procedure every time you recompile an extension, unless you are sure the AFS installation directories are still valid. =head2 Static Linking of a new Perl Binary An extension that is built with the above steps is ready to use on systems supporting dynamic loading. On systems that do not support dynamic loading, any newly created extension has to be linked together with the available resources. MakeMaker supports the linking process by creating appropriate targets in the Makefile whenever an extension is built. You can invoke the corresponding section of the makefile with make perl That produces a new perl binary in the current directory with all extensions linked in that can be found in INST_ARCHLIB, SITELIBEXP, and PERL_ARCHLIB. To do that, MakeMaker writes a new Makefile, on UNIX, this is called F (may be system dependent). If you want to force the creation of a new perl, it is recommended that you delete this F, so the directories are searched through for linkable libraries again. The binary can be installed into the directory where perl normally resides on your machine with make inst_perl To produce a perl binary with a different name than C, either say perl Makefile.PL MAP_TARGET=myperl make myperl make inst_perl or say perl Makefile.PL make myperl MAP_TARGET=myperl make inst_perl MAP_TARGET=myperl In any case you will be prompted with the correct invocation of the C target that installs the new binary into INSTALLBIN. make inst_perl by default writes some documentation of what has been done into the file C<$(INSTALLARCHLIB)/perllocal.pod>. This can be bypassed by calling make pure_inst_perl. Warning: the inst_perl: target will most probably overwrite your existing perl binary. Use with care! Sometimes you might want to build a statically linked perl although your system supports dynamic loading. In this case you may explicitly set the linktype with the invocation of the Makefile.PL or make: perl Makefile.PL LINKTYPE=static # recommended or make LINKTYPE=static # works on most systems =head2 Determination of Perl Library and Installation Locations MakeMaker needs to know, or to guess, where certain things are located. Especially INST_LIB and INST_ARCHLIB (where to put the files during the make(1) run), PERL_LIB and PERL_ARCHLIB (where to read existing modules from), and PERL_INC (header files and C). Extensions may be built either using the contents of the perl source directory tree or from the installed perl library. The recommended way is to build extensions after you have run 'make install' on perl itself. You can do that in any directory on your hard disk that is not below the perl source tree. The support for extensions below the ext directory of the perl distribution is only good for the standard extensions that come with perl. If an extension is being built below the C directory of the perl source then MakeMaker will set PERL_SRC automatically (e.g., C<../..>). If PERL_SRC is defined and the extension is recognized as a standard extension, then other variables default to the following: PERL_INC = PERL_SRC PERL_LIB = PERL_SRC/lib PERL_ARCHLIB = PERL_SRC/lib INST_LIB = PERL_LIB INST_ARCHLIB = PERL_ARCHLIB If an extension is being built away from the perl source then MakeMaker will leave PERL_SRC undefined and default to using the installed copy of the perl library. The other variables default to the following: PERL_INC = $archlibexp/CORE PERL_LIB = $privlibexp PERL_ARCHLIB = $archlibexp INST_LIB = ./blib/lib INST_ARCHLIB = ./blib/arch If perl has not yet been installed then PERL_SRC can be defined on the command line as shown in the previous section. =head2 Which architecture dependent directory? If you don't want to keep the defaults for the INSTALL* macros, MakeMaker helps you to minimize the typing needed: the usual relationship between INSTALLPRIVLIB and INSTALLARCHLIB is determined by Configure at perl compilation time. MakeMaker supports the user who sets INSTALLPRIVLIB. If INSTALLPRIVLIB is set, but INSTALLARCHLIB not, then MakeMaker defaults the latter to be the same subdirectory of INSTALLPRIVLIB as Configure decided for the counterparts in %Config, otherwise it defaults to INSTALLPRIVLIB. The same relationship holds for INSTALLSITELIB and INSTALLSITEARCH. MakeMaker gives you much more freedom than needed to configure internal variables and get different results. It is worth mentioning that make(1) also lets you configure most of the variables that are used in the Makefile. But in the majority of situations this will not be necessary, and should only be done if the author of a package recommends it (or you know what you're doing). =head2 Using Attributes and Parameters The following attributes may be specified as arguments to WriteMakefile() or as NAME=VALUE pairs on the command line. Attributes that became available with later versions of MakeMaker are indicated. In order to maintain portability of attributes with older versions of MakeMaker you may want to use L with your C. =over 2 =item ABSTRACT One line description of the module. Will be included in PPD file. =item ABSTRACT_FROM Name of the file that contains the package description. MakeMaker looks for a line in the POD matching /^($package\s-\s)(.*)/. This is typically the first line in the "=head1 NAME" section. $2 becomes the abstract. =item AUTHOR Array of strings containing name (and email address) of package author(s). Is used in CPAN Meta files (META.yml or META.json) and PPD (Perl Package Description) files for PPM (Perl Package Manager). =item BINARY_LOCATION Used when creating PPD files for binary packages. It can be set to a full or relative path or URL to the binary archive for a particular architecture. For example: perl Makefile.PL BINARY_LOCATION=x86/Agent.tar.gz builds a PPD package that references a binary of the C package, located in the C directory relative to the PPD itself. =item BUILD_REQUIRES Available in version 6.55_03 and above. A hash of modules that are needed to build your module but not run it. This will go into the C field of your F and the C of the C field of your F. Defaults to C<<< { "ExtUtils::MakeMaker" => 0 } >>> if this attribute is not specified. The format is the same as PREREQ_PM. =item C Ref to array of *.c file names. Initialised from a directory scan and the values portion of the XS attribute hash. This is not currently used by MakeMaker but may be handy in Makefile.PLs. =item CCFLAGS String that will be included in the compiler call command line between the arguments INC and OPTIMIZE. =item CONFIG Arrayref. E.g. [qw(archname manext)] defines ARCHNAME & MANEXT from config.sh. MakeMaker will add to CONFIG the following values anyway: ar cc cccdlflags ccdlflags dlext dlsrc ld lddlflags ldflags libc lib_ext obj_ext ranlib sitelibexp sitearchexp so =item CONFIGURE CODE reference. The subroutine should return a hash reference. The hash may contain further attributes, e.g. {LIBS =E ...}, that have to be determined by some evaluation method. =item CONFIGURE_REQUIRES Available in version 6.52 and above. A hash of modules that are required to run Makefile.PL itself, but not to run your distribution. This will go into the C field of your F and the C of the C field of your F. Defaults to C<<< { "ExtUtils::MakeMaker" => 0 } >>> if this attribute is not specified. The format is the same as PREREQ_PM. =item DEFINE Something like C<"-DHAVE_UNISTD_H"> =item DESTDIR This is the root directory into which the code will be installed. It I. For example, if your code would normally go into F you could set DESTDIR=~/tmp/ and installation would go into F<~/tmp/usr/local/lib/perl>. This is primarily of use for people who repackage Perl modules. NOTE: Due to the nature of make, it is important that you put the trailing slash on your DESTDIR. F<~/tmp/> not F<~/tmp>. =item DIR Ref to array of subdirectories containing Makefile.PLs e.g. ['sdbm'] in ext/SDBM_File =item DISTNAME A safe filename for the package. Defaults to NAME below but with :: replaced with -. For example, Foo::Bar becomes Foo-Bar. =item DISTVNAME Your name for distributing the package with the version number included. This is used by 'make dist' to name the resulting archive file. Defaults to DISTNAME-VERSION. For example, version 1.04 of Foo::Bar becomes Foo-Bar-1.04. On some OS's where . has special meaning VERSION_SYM may be used in place of VERSION. =item DLEXT Specifies the extension of the module's loadable object. For example: DLEXT => 'unusual_ext', # Default value is $Config{so} NOTE: When using this option to alter the extension of a module's loadable object, it is also necessary that the module's pm file specifies the same change: local $DynaLoader::dl_dlext = 'unusual_ext'; =item DL_FUNCS Hashref of symbol names for routines to be made available as universal symbols. Each key/value pair consists of the package name and an array of routine names in that package. Used only under AIX, OS/2, VMS and Win32 at present. The routine names supplied will be expanded in the same way as XSUB names are expanded by the XS() macro. Defaults to {"$(NAME)" => ["boot_$(NAME)" ] } e.g. {"RPC" => [qw( boot_rpcb rpcb_gettime getnetconfigent )], "NetconfigPtr" => [ 'DESTROY'] } Please see the L documentation for more information about the DL_FUNCS, DL_VARS and FUNCLIST attributes. =item DL_VARS Array of symbol names for variables to be made available as universal symbols. Used only under AIX, OS/2, VMS and Win32 at present. Defaults to []. (e.g. [ qw(Foo_version Foo_numstreams Foo_tree ) ]) =item EXCLUDE_EXT Array of extension names to exclude when doing a static build. This is ignored if INCLUDE_EXT is present. Consult INCLUDE_EXT for more details. (e.g. [ qw( Socket POSIX ) ] ) This attribute may be most useful when specified as a string on the command line: perl Makefile.PL EXCLUDE_EXT='Socket Safe' =item EXE_FILES Ref to array of executable files. The files will be copied to the INST_SCRIPT directory. Make realclean will delete them from there again. If your executables start with something like #!perl or #!/usr/bin/perl MakeMaker will change this to the path of the perl 'Makefile.PL' was invoked with so the programs will be sure to run properly even if perl is not in /usr/bin/perl. =item FIRST_MAKEFILE The name of the Makefile to be produced. This is used for the second Makefile that will be produced for the MAP_TARGET. Defaults to 'Makefile' or 'Descrip.MMS' on VMS. (Note: we couldn't use MAKEFILE because dmake uses this for something else). =item FULLPERL Perl binary able to run this extension, load XS modules, etc... =item FULLPERLRUN Like PERLRUN, except it uses FULLPERL. =item FULLPERLRUNINST Like PERLRUNINST, except it uses FULLPERL. =item FUNCLIST This provides an alternate means to specify function names to be exported from the extension. Its value is a reference to an array of function names to be exported by the extension. These names are passed through unaltered to the linker options file. =item H Ref to array of *.h file names. Similar to C. =item IMPORTS This attribute is used to specify names to be imported into the extension. Takes a hash ref. It is only used on OS/2 and Win32. =item INC Include file dirs eg: C<"-I/usr/5include -I/path/to/inc"> =item INCLUDE_EXT Array of extension names to be included when doing a static build. MakeMaker will normally build with all of the installed extensions when doing a static build, and that is usually the desired behavior. If INCLUDE_EXT is present then MakeMaker will build only with those extensions which are explicitly mentioned. (e.g. [ qw( Socket POSIX ) ]) It is not necessary to mention DynaLoader or the current extension when filling in INCLUDE_EXT. If the INCLUDE_EXT is mentioned but is empty then only DynaLoader and the current extension will be included in the build. This attribute may be most useful when specified as a string on the command line: perl Makefile.PL INCLUDE_EXT='POSIX Socket Devel::Peek' =item INSTALLARCHLIB Used by 'make install', which copies files from INST_ARCHLIB to this directory if INSTALLDIRS is set to perl. =item INSTALLBIN Directory to install binary files (e.g. tkperl) into if INSTALLDIRS=perl. =item INSTALLDIRS Determines which of the sets of installation directories to choose: perl, site or vendor. Defaults to site. =item INSTALLMAN1DIR =item INSTALLMAN3DIR These directories get the man pages at 'make install' time if INSTALLDIRS=perl. Defaults to $Config{installman*dir}. If set to 'none', no man pages will be installed. =item INSTALLPRIVLIB Used by 'make install', which copies files from INST_LIB to this directory if INSTALLDIRS is set to perl. Defaults to $Config{installprivlib}. =item INSTALLSCRIPT Available in version 6.30_02 and above. Used by 'make install' which copies files from INST_SCRIPT to this directory if INSTALLDIRS=perl. =item INSTALLSITEARCH Used by 'make install', which copies files from INST_ARCHLIB to this directory if INSTALLDIRS is set to site (default). =item INSTALLSITEBIN Used by 'make install', which copies files from INST_BIN to this directory if INSTALLDIRS is set to site (default). =item INSTALLSITELIB Used by 'make install', which copies files from INST_LIB to this directory if INSTALLDIRS is set to site (default). =item INSTALLSITEMAN1DIR =item INSTALLSITEMAN3DIR These directories get the man pages at 'make install' time if INSTALLDIRS=site (default). Defaults to $(SITEPREFIX)/man/man$(MAN*EXT). If set to 'none', no man pages will be installed. =item INSTALLSITESCRIPT Used by 'make install' which copies files from INST_SCRIPT to this directory if INSTALLDIRS is set to site (default). =item INSTALLVENDORARCH Used by 'make install', which copies files from INST_ARCHLIB to this directory if INSTALLDIRS is set to vendor. Note that if you do not set this, the value of INSTALLVENDORLIB will be used, which is probably not what you want. =item INSTALLVENDORBIN Used by 'make install', which copies files from INST_BIN to this directory if INSTALLDIRS is set to vendor. =item INSTALLVENDORLIB Used by 'make install', which copies files from INST_LIB to this directory if INSTALLDIRS is set to vendor. =item INSTALLVENDORMAN1DIR =item INSTALLVENDORMAN3DIR These directories get the man pages at 'make install' time if INSTALLDIRS=vendor. Defaults to $(VENDORPREFIX)/man/man$(MAN*EXT). If set to 'none', no man pages will be installed. =item INSTALLVENDORSCRIPT Available in version 6.30_02 and above. Used by 'make install' which copies files from INST_SCRIPT to this directory if INSTALLDIRS is set to vendor. =item INST_ARCHLIB Same as INST_LIB for architecture dependent files. =item INST_BIN Directory to put real binary files during 'make'. These will be copied to INSTALLBIN during 'make install' =item INST_LIB Directory where we put library files of this extension while building it. =item INST_MAN1DIR Directory to hold the man pages at 'make' time =item INST_MAN3DIR Directory to hold the man pages at 'make' time =item INST_SCRIPT Directory where executable files should be installed during 'make'. Defaults to "./blib/script", just to have a dummy location during testing. make install will copy the files in INST_SCRIPT to INSTALLSCRIPT. =item LD Program to be used to link libraries for dynamic loading. Defaults to $Config{ld}. =item LDDLFLAGS Any special flags that might need to be passed to ld to create a shared library suitable for dynamic loading. It is up to the makefile to use it. (See L) Defaults to $Config{lddlflags}. =item LDFROM Defaults to "$(OBJECT)" and is used in the ld command to specify what files to link/load from (also see dynamic_lib below for how to specify ld flags) =item LIB LIB should only be set at C time but is allowed as a MakeMaker argument. It has the effect of setting both INSTALLPRIVLIB and INSTALLSITELIB to that value regardless any explicit setting of those arguments (or of PREFIX). INSTALLARCHLIB and INSTALLSITEARCH are set to the corresponding architecture subdirectory. =item LIBPERL_A The filename of the perllibrary that will be used together with this extension. Defaults to libperl.a. =item LIBS An anonymous array of alternative library specifications to be searched for (in order) until at least one library is found. E.g. 'LIBS' => ["-lgdbm", "-ldbm -lfoo", "-L/path -ldbm.nfs"] Mind, that any element of the array contains a complete set of arguments for the ld command. So do not specify 'LIBS' => ["-ltcl", "-ltk", "-lX11"] See ODBM_File/Makefile.PL for an example, where an array is needed. If you specify a scalar as in 'LIBS' => "-ltcl -ltk -lX11" MakeMaker will turn it into an array with one element. =item LICENSE Available in version 6.31 and above. The licensing terms of your distribution. Generally it's "perl_5" for the same license as Perl itself. See L for the list of options. Defaults to "unknown". =item LINKTYPE 'static' or 'dynamic' (default unless usedl=undef in config.sh). Should only be used to force static linking (also see linkext below). =item MAGICXS Available in version 6.8305 and above. When this is set to C<1>, C
