However, if I change the above question a... (1 Reply)

module::install::compiler
Module::Install::Compiler(3) User Contributed Perl Documentation Module::Install::Compiler(3) NAME
Module::Install::Compiler - Commands for interacting with the C compiler SYNOPSIS
To be completed DESCRIPTION
Many Perl modules that contains C and XS code have fiendishly complex Makefile.PL files, because ExtUtils::MakeMaker doesn't itself provide a huge amount of assistance and automation in this area. Module::Install::Compiler provides a number of commands that take care of common utility tasks, and try to take some of intricacy out of creating C and XS modules. COMMANDS
To be completed TO DO
The current implementation is relatively fragile and minimalistic. It only handles some very basic wrapper around ExtUtils::MakeMaker. It is currently undergoing extensive refactoring to provide a more generic compiler flag generation capability. This may take some time, and if anyone who maintains a Perl module that makes use of the compiler would like to help out, your assistance would be greatly appreciated. SEE ALSO
