-ExtUtils::MakeMaker - create an extension Makefile
+ExtUtils::MakeMaker - Create a module Makefile
=head1 SYNOPSIS
=head2 How To Write A Makefile.PL
-The short answer is: Don't.
-
- Always begin with h2xs.
- Always begin with h2xs!
- ALWAYS BEGIN WITH H2XS!
-
-even if you're not building around a header file, and even if you
-don't have an XS component.
-
-Run h2xs(1) before you start thinking about writing a module. For so
-called pm-only modules that consist of C<*.pm> files only, h2xs has
-the C<-X> switch. This will generate dummy files of all kinds that are
-useful for the module developer.
-
-The medium answer is:
-
- use ExtUtils::MakeMaker;
- WriteMakefile( NAME => "Foo::Bar" );
+See ExtUtils::MakeMaker::Tutorial.
The long answer is the rest of the manpage :-)
=head2 make test
MakeMaker checks for the existence of a file named F<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.

-module with the C<-I> switches set correctly.
+execute all matching files in alphabetical order via the

+
+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

F<test.pl> exists in the current directory, it is used for the test.

=over 2
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.
+
+From the GNU Makefile conventions.
+
=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.
+
+=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 DL_FUNCS
=item FIRST_MAKEFILE
-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
+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
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<Config/lddlflags>)
+
+Defaults to $Config{lddlflags}.
+
=item LDFROM
Defaults to "$(OBJECT)" and is used in the ld command to specify
make a perl. This is handled automatically as a switch by
MakeMaker. The user normally does not need it.
-=item MAKEFILE
+=item MAKEFILE_OLD
+
+When 'make clean' or similar is run, the $(FIRST_MAKEFILE) will be
+backed up at this location.
-The name of the Makefile to be produced.
+Defaults to $(FIRST_MAKEFILE).old or $(FIRST_MAKEFILE)_old on VMS.
=item MAN1PODS
=item NOECHO
-Defaults to C<@>. By setting it to an empty string you can generate a
-Makefile that echos all commands. Mainly used in debugging MakeMaker
-itself.
+Command so make does not print the literal commands its running.
+
+By setting it to an empty string you can generate a Makefile that
+prints all commands. Mainly used in debugging MakeMaker itself.
+
+Defaults to C<@>.
=item NORECURS
system resources, error detection, memory usage reporting, catchable failure
of memory allocations, etc.
+=item PERLPREFIX
+
+Directory under which core modules are to be installed.
+
+Defaults to $Config{installprefixexp} falling back to
+$Config{installprefix}, $Config{prefixexp} or $Config{prefix} should
+$Config{installprefixexp} not exist.
+
+Overridden by PREFIX.
+
=item PERLRUN
Use this instead of $(PERL) when you wish to run perl. It will set up
If you specify LIB or any INSTALL* variables they will not be effected
by the PREFIX.
-Defaults to $Config{installprefixexp}.
-
-=item PREREQ_PM
-
-Hashref: Names of modules that need to be available to run this
-extension (e.g. Fcntl for SDBM_File) are the keys of the hash and the
-desired version is the value. If the required version number is 0, we
-only check if any version is installed already.
-
=item PREREQ_FATAL
Bool. If this parameter is true, failing to have the required modules
It is I<extremely> rare to have to use C<PREREQ_FATAL> at all!
+=item PREREQ_PM
+

+
=item PREREQ_PRINT
Bool. If this parameter is true, the prerequisites will be printed to
=item SITEPREFIX
-Like PREFIX, but only for the site install locations.
+Like PERLPREFIX, but only for the site install locations.
-Defaults to PREFIX (if set) or $Config{siteprefixexp}. Perls prior to
-5.6.0 didn't have an explicit siteprefix in the Config. In those

+Defaults to $Config{siteprefixexp}. Perls prior to 5.6.0 didn't have

=item VERBINST

See attribute C<depend> below.
+=item VERSION_SYM
+
+A sanitized VERSION with . replaced by _. For places where . has
+special meaning (some filesystems, RCS labels, etc...)
+
=item XS
Hashref of .xs files. MakeMaker will default this. e.g.
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 => { }>>.

+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.
