# In a Build.PL : use Module::Build; my $build = Module::Build->new ( module_name => 'Foo::Bar', license => 'perl', create_makefile_pl => 'traditional' ); ...
"ExtUtils::MakeMaker"has been the standard way to distribute modules for a long time, many tools (CPAN.pm, or your system administrator) may expect to find a working Makefile.PL in every distribution they download from CPAN. If you want to throw them a bone, you can use
"Module::Build::Compat"to automatically generate a Makefile.PL for you, in one of several different styles.
"Module::Build::Compat"also provides some code that helps out the Makefile.PL at runtime.
- create_makefile_pl($style, $build)
- Creates a Makefile.PL in the current directory in one of several styles, based on the supplied
$build. This is typically controlled by passing the desired style as the
"new()"method; the Makefile.PL will then be automatically created during the
The currently supported styles are:
- A Makefile.PL will be created in the ``traditional style, i.e. it will use
"ExtUtils::MakeMaker"and won't rely on
"Module::Build"at all. In order to create the Makefile.PL'', we'll include the
"build_requires"dependencies as the
"perl Build.PL"stage you ask the user questions, or do some auto-sensing about the user's environment, or if you subclass
"Module::Build"to do some customization, because the vanilla Makefile.PL won't do any of that.
- A small Makefile.PL will be created that passes all functionality through to the Build.PL script in the same directory. The user must already have
"Module::Build"installed in order to use this, or else they'll get a module-not-found error.:
- passthrough (DEPRECATED)
- This is just like the
"small"option above, but if
"Module::Build"is not already installed on the user's system, the script will offer to use
"CPAN.pm"to download it and install it before continuing with the build.
"configure_requires"metadata property and install Module::Build before running Build.PL if Module::Build is listed and Module::Build now adds itself to configure_requires by default. Perl 5.10.1 includes
"configure_requires"support. In the future, when
"configure_requires"support is deemed sufficiently widespread, the
"passthrough"style will be removed.
- run_build_pl(args => \@ARGV)
- This method runs the Build.PL script, passing it any arguments the user may have supplied to the
"perl Makefile.PL"command. Because
"Module::Build"accept different arguments, this method also performs some translation between the two.
"run_build_pl()"accepts the following named parameters:
"args"parameter specifies the parameters that would usually appear on the command line of the
"perl Makefile.PL"command - typically you'll just pass a reference to
- This is the filename of the script to run - it defaults to
- This method writes a 'dummy' Makefile that will pass all commands through to the corresponding
"write_makefile()"accepts the following named parameters:
- The name of the file to write - defaults to the string
So, some common scenarios are:
- Just include a Build.PL script (without a Makefile.PL script), and give installation directions in a README or INSTALL document explaining how to install the module. In particular, explain that the user must install
"Module::Build"before installing your module.
"ExtUtils::MakeMaker"way of doing things.
- Include a Build.PL script and a ``traditional Makefile.PL, created either manually or with
"create_makefile_pl()". Users won't ever have to install
"Module::Build"if they use the Makefile.PL'', but they won't get to take advantage of
"Module::Build"'s extra features either.
For good measure, of course, test both the Makefile.PL and the Build.PL before shipping.
- Include a Build.PL script and a ``pass-through Makefile.PL built using
"Module::Build::Compat". This will mean that people can continue to use the ``old installation commands, and they may never notice that it's actually doing something else behind the scenes. It will also mean that your installation process is compatible with older versions of tools like CPAN and CPANPLUS.:
