=head1 NAME
-ExtUtils::MakeMaker - create an extension Makefile
+ExtUtils::MakeMaker - Create a module Makefile
=head1 SYNOPSIS
-C<use ExtUtils::MakeMaker;>
-
-C<WriteMakefile( ATTRIBUTE =E<gt> VALUE [, ...] );>
-
-which is really
+ use ExtUtils::MakeMaker;
-C<MM-E<gt>new(\%att)-E<gt>flush;>
+ WriteMakefile( ATTRIBUTE => VALUE [, ...] );
=head1 DESCRIPTION
that can be individually overridden. Each subroutine returns the text
it wishes to have written to the Makefile.
-=head2 Hintsfile support
-
-MakeMaker.pm uses the architecture specific information from
-Config.pm. In addition it evaluates architecture specific hints files
-in a C<hints/> directory. The hints files are expected to be named
-like their counterparts in C<PERL_SRC/hints>, but with an C<.pl> file
-name extension (eg. C<next_3_2.pl>). They are simply C<eval>ed by
-MakeMaker within the WriteMakefile() subroutine, and can be used to
-execute commands as well as to include special variables. The rules
-which hintsfile is chosen are the same as in Configure.
-
-The hintsfile is eval()ed immediately after the arguments given to
-WriteMakefile are stuffed into a hash reference $self but before this
-reference becomes blessed. So if you want to do the equivalent to
-override or create an attribute you would say something like
-
- $self->{LIBS} = ['-ldbm -lucb -lc'];
-
-=head2 What's new in version 5 of MakeMaker
-
-MakeMaker 5 is pure object oriented. This allows us to write an
-unlimited number of Makefiles with a single perl process. 'perl
-Makefile.PL' with MakeMaker 5 goes through all subdirectories
-immediately and evaluates any Makefile.PL found in the next level
-subdirectories. The benefit of this approach comes in useful for both
-single and multi directories extensions.
-
-Multi directory extensions have an immediately visible speed
-advantage, because there's no startup penalty for any single
-subdirectory Makefile.
-
-Single directory packages benefit from the much improved
-needs_linking() method. As the main Makefile knows everything about
-the subdirectories, a needs_linking() method can now query all
-subdirectories if there is any linking involved down in the tree. The
-speedup for PM-only Makefiles seems to be around 1 second on my
-Indy 100 MHz.
-
-=head2 Incompatibilities between MakeMaker 5.00 and 4.23
-
-There are no incompatibilities in the short term, as all changes are
-accompanied by short-term workarounds that guarantee full backwards
-compatibility.
-
-You are likely to face a few warnings that expose deprecations which
-will result in incompatibilities in the long run:
-
-You should not use %att directly anymore. Instead any subroutine you
-override in the MY package will be called by the object method, so you
-can access all object attributes directly via the object in $_[0].
+MakeMaker 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().
-You should not call the class methos MM->something anymore. Instead
-you should call the superclass. Something like
+=head2 How To Write A Makefile.PL
- sub MY::constants {
- my $self = shift;
- $self->MM::constants();
- }
-
-Especially the libscan() and exescan() methods should be altered
-towards OO programming, that means do not expect that $_ to contain
-the path but rather $_[1].
-
-Try to build several extensions simultanously to debug your
-Makefile.PL. You can unpack a bunch of distributed packages within one
-directory and run
-
- perl -MExtUtils::MakeMaker -e 'WriteMakefile()'
-
-That's actually fun to watch :)
-
-Final suggestion: Try to delete all of your MY:: subroutines and
-watch, if you really still need them. MakeMaker might already do what
-you want without them. That's all about it.
+See ExtUtils::MakeMaker::Tutorial.
+The long answer is the rest of the manpage :-)
=head2 Default Makefile Behaviour
-The automatically generated Makefile enables the user of the extension
-to invoke
+The generated Makefile enables the user of the extension to invoke
perl Makefile.PL # optionally "perl Makefile.PL verbose"
make
=head2 make test
-MakeMaker checks for the existence of a file named "test.pl" in the
-current directory and if it exists it adds commands to the test target
-of the generated Makefile that will execute the script with the proper
-set of perl C<-I> options.
+MakeMaker checks for the existence of a file named F<test.pl> in the
+current directory and if it exists it execute the script with the
+proper set of perl C<-I> options.
MakeMaker also checks for any files matching glob("t/*.t"). It will
-add commands to the test target of the generated Makefile that execute
-all matching files via the L<Test::Harness> module with the C<-I>
-switches set correctly.
+execute all matching files in alphabetical order via the
+L<Test::Harness> module with the C<-I> switches set correctly.
+
+If you'd like to see the raw output of your tests, set the
+C<TEST_VERBOSE> variable to true.
+
+ make test TEST_VERBOSE=1
+
+=head2 make testdb
+
+A useful variation of the above is the target C<testdb>. It runs the
+test under the Perl debugger (see L<perldebug>). If the file
+F<test.pl> exists in the current directory, it is used for the test.
+
+If you want to debug some other testfile, set the C<TEST_FILE> 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<TESTDB_SW> 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_EXE, INST_MAN1DIR, and
-INST_MAN3DIR. All these default to something below ./blib if
-you are I<not> building below the perl source directory. If you I<are>
+the macros INST_LIB, INST_ARCHLIB, INST_SCRIPT, INST_MAN1DIR and
+INST_MAN3DIR. All these default to something below ./blib if you are
+I<not> building below the perl source directory. If you I<are>
building below the perl source, INST_LIB and INST_ARCHLIB default to
- ../../lib, and INST_EXE is not defined.
+../../lib, and INST_SCRIPT is not defined.
The I<install> 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
+ INSTALLDIRS set to
+ perl site vendor
- INST_LIB INSTALLPRIVLIB INSTALLSITELIB
- INST_ARCHLIB INSTALLARCHLIB INSTALLSITEARCH
- INST_EXE INSTALLBIN
- INST_MAN1DIR INSTALLMAN1DIR
- INST_MAN3DIR INSTALLMAN3DIR
+ PERLPREFIX SITEPREFIX VENDORPREFIX
+ INST_ARCHLIB INSTALLARCHLIB INSTALLSITEARCH INSTALLVENDORARCH
+ INST_LIB INSTALLPRIVLIB INSTALLSITELIB INSTALLVENDORLIB
+ INST_BIN INSTALLBIN INSTALLSITEBIN INSTALLVENDORBIN
+ INST_SCRIPT INSTALLSCRIPT INSTALLSCRIPT INSTALLSCRIPT
+ 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.
-If you don't want to keep the defaults, 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.
+You can check the values of these variables on your system with
-MakeMaker gives you much more freedom than needed to configure
-internal variables and get different results. It is worth to mention,
-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.

+=head2 PREFIX and LIB attribute
-The PREFIX attribute can be used to set the INSTALL* attributes in one
-go. The quickest way to install a module in a non-standard place
+PREFIX and LIB can be used to set several INSTALL* attributes in one
+go. The quickest way to install a module in a non-standard place might
+be
perl Makefile.PL PREFIX=~
-This will replace the string specified by $Config{prefix} in all
-$Config{install*} values.
+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).
+
+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.

+by perl by default, nor by make.

-INST_LIBDIR = C<$(INST_LIB)$(ROOTEXT)>
+=head2 Using Attributes and Parameters
-INST_AUTODIR = C<$(INST_LIB)/auto/$(FULLEXT)>

+=item ABSTRACT_FROM
-# The following "=item C" is used by the attrib_help routine

+=item AUTHOR
+
+String containing name (and email address) of package author(s). Is used
+in 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
+

Something like C<"-DHAVE_UNISTD_H">
+=item DESTDIR
+
+This is the root directory into which the code will be installed. It
+I<prepends itself to the normal prefix>. For example, if your code
+would normally go into /usr/local/lib/perl you could set DESTDIR=/tmp/
+and installation would go into /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. "/tmp/" not "/tmp".

=item DIR
Ref to array of subdirectories containing Makefile.PLs e.g. [ 'sdbm'
=item DISTNAME
-Your name for distributing the package (by tar file). This defaults to
-NAME above.
+A safe filename for the package.
+
+Defaults to NAME above but with :: replaced with -.
+
+For example, Foo::Bar becomes Foo-Bar.

+
+Your name for distributing the package with the version number
+included. This is used by 'make dist' to name the resulting archive
+file.

+
+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 ) ] )

=item EXE_FILES
Ref to array of executable files. The files will be copied to the
-INST_EXE directory. Make realclean will delete them from there
+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.

-The name of the Makefile to be produced. Defaults to the contents of
-MAKEFILE, but can be overridden. This is used for the second Makefile
-that will be produced for the MAP_TARGET.
+The name of the Makefile to be produced. This is used for the second

+
+=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

=head2 Overriding MakeMaker Methods
If you cannot achieve the desired Makefile behaviour by specifying
attributes you may define private subroutines in the Makefile.PL.
-Each subroutines returns the text it wishes to have written to
+Each subroutine returns the text it wishes to have written to
the Makefile. To override a section of the Makefile you can
either say:
- sub MY::c_o { "new literal text" }
+ sub MY::c_o { "new literal text" }
or you can edit the default by saying something like:
- sub MY::c_o {
- my $self = shift;
- local *c_o;
- $_=$self->MM::c_o;
- s/old text/new text/;
- $_;
- }
+ package MY; # so that "SUPER" works right
+ sub c_o {
+ my $inherited = shift->SUPER::c_o(@_);
+ $inherited =~ s/old text/new text/;
+ $inherited;
+ }
-Both methods above are available for backwards compatibility with
-older Makefile.PLs.
+If you are running experiments with embedding perl as a library into
+other applications, you might find MakeMaker is not sufficient. You'd
+better have a look at ExtUtils::Embed which is a collection of utilities
+for embedding.
If you still need a different solution, try to develop another
-subroutine, that fits your needs and submit the diffs to
-F<perl5-porters@nicoh.com> or F<comp.lang.perl.misc> as appropriate.
+subroutine that fits your needs and submit the diffs to
+F<makemaker@perl.org>
+
+For a complete description of all MakeMaker methods see
+L<ExtUtils::MM_Unix>.
+
+Here is a simple example of how to add a new target to the generated
+Makefile:
+
+ sub MY::postamble {
+ return <<'MAKE_FRAG';
+ $(MYEXTLIB): sdbm/Makefile
+ cd sdbm && $(MAKE) all
+
+ MAKE_FRAG
+ }
+
+=head2 The End Of Cargo Cult Programming
+
+WriteMakefile() now does some basic sanity checks on its parameters to
+protect against typos and malformatted values. This means some things
+which happened to work in the past will now throw warnings and
+possibly produce internal errors.
+
+Some of the most common mistakes:
+
+=over 2
+
+=item C<<MAN3PODS => ' '>>
+
+This is commonly used to supress the creation of man pages. MAN3PODS
+takes a hash ref not a string, but the above worked by accident in old
+versions of MakeMaker.
+
+The correct code is C<<MAN3PODS => { }>>.
+
+=back
+
+
+=head2 Hintsfile support
+
+MakeMaker.pm uses the architecture specific information from
+Config.pm. In addition it evaluates architecture specific hints files
+in a C<hints/> directory. The hints files are expected to be named
+like their counterparts in C<PERL_SRC/hints>, but with an C<.pl> file
+name extension (eg. C<next_3_2.pl>). They are simply C<eval>ed by
+MakeMaker within the WriteMakefile() subroutine, and can be used to
+execute commands as well as to include special variables. The rules
+which hintsfile is chosen are the same as in Configure.
+
+The hintsfile is eval()ed immediately after the arguments given to
+WriteMakefile are stuffed into a hash reference $self but before this
+reference becomes blessed. So if you want to do the equivalent to
+override or create an attribute you would say something like
+
+ $self->{LIBS} = ['-ldbm -lucb -lc'];

+
+=head2 Module Meta-Data
+
+Long plaguing users of MakeMaker based modules has been the problem of
+getting basic information about the module out of the sources
+I<without> running the F<Makefile.PL> and doing a bunch of messy
+heuristics on the resulting F<Makefile>. To this end a simple module
+meta-data file has been introduced, F<META.yml>.
+
+F<META.yml> is a YAML document (see http://www.yaml.org) containing
+basic information about the module (name, version, prerequisites...)
+in an easy to read format. The format is developed and defined by the
+Module::Build developers (see
+http://module-build.sourceforge.net/META-spec.html)
+
+MakeMaker will automatically generate a F<META.yml> file for you and
+add it to your F<MANIFEST> as part of the 'distdir' target (and thus
+the 'dist' target). This is intended to seamlessly and rapidly
+populate CPAN with module meta-data. If you wish to shut this feature
+off, set the C<NO_META> C<WriteMakefile()> flag to true.
+
+
+=head2 Disabling an extension
+If some events detected in F<Makefile.PL> imply that there is no way
+to create the Module, but this is a normal state of things, then you
+can create a F<Makefile> which does nothing, but succeeds on all the
+"usual" build targets. To do so, use
+
+ ExtUtils::MakeMaker::WriteEmptyMakefile();
+
+instead of WriteMakefile().
+
+This may be useful if other modules expect this module to be I<built>
+OK, as opposed to I<work> OK (say, this system-dependent module builds
+in a subdirectory of some other distribution, or is listed as a
+dependency in a CPAN::Bundle, but the functionality is supported by
+different means on the current architecture).
+
+=head2 Other Handy Functions
+
+=over 4
+
+=item prompt
+
+ my $value = prompt($message);
+ my $value = prompt($message, $default);
+
+The C<prompt()> function provides an easy way to request user input
+used to write a makefile. It displays the $message as a prompt for
+input. If a $default is provided it will be used as a default. The
+function returns the $value selected by the user.
+
+If C<prompt()> detects that it is not running interactively and there
+is nothing on STDIN or if the PERL_MM_USE_DEFAULT environment variable
+is set to true, the $default will be used without prompting. This
+prevents automated processes from blocking on user input.
+
+If no $default is provided an empty string will be used instead.

+Command line options used by C<MakeMaker-E<gt>new()>, and thus by

+is processed before any actual command line arguments are processed.
+
+=item PERL_MM_USE_DEFAULT
