Module::Build::Compat - Compatibility with ExtUtils::MakeMaker
# In a Build.PL : use Module::Build; my $build = Module::Build->new ( module_name => 'Foo::Bar', license => 'perl', create_makefile_pl => 'passthrough' ); ...
Because 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.
Creates a Makefile.PL in the current directory in one of several styles, based on the supplied Module::Build object
$build. This is typically controlled by passing the desired style as the
create_makefile_pl parameter to Module::Build's
new() method; the Makefile.PL will then be automatically created during the
The currently supported styles are:
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.
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.
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
You don't want to use this style if during 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.
This method runs the Build.PL script, passing it any arguments the user may have supplied to the
perl Makefile.PL command. Because ExtUtils::MakeMaker and Module::Build accept different arguments, this method also performs some translation between the two.
run_build_pl() accepts the following named parameters:
This method writes a 'dummy' Makefile that will pass all commands through to the corresponding Module::Build actions.
write_makefile() accepts the following named parameters:
The name of the file to write - defaults to the string
So, some common scenarios are:
Note that if you do this, you may make things easier for yourself, but harder for people with older versions of CPAN or CPANPLUS on their system, because those tools generally only understand the Makefile.PL/
ExtUtils::MakeMaker way of doing things.
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.
