270 | ||
271 | The packages below implement functions for generating properly | |
3c4b39be | 272 | formatted commandlines for the compiler being used. Each package |
6b09c160 YST |
273 | defines two primary functions 'format_linker_cmd()' & |
274 | 'format_compiler_cmd()' that accepts a list of named arguments (a | |
3c4b39be | 275 | hash) and returns a list of formatted options suitable for invoking the |
6b09c160 YST |
276 | compiler. By default, if the compiler supports scripting of its |
277 | operation then a script file is built containing the options while | |
278 | those options are removed from the commandline, and a reference to the | |
279 | script is pushed onto the commandline in their place. Scripting the | |
280 | compiler in this way helps to avoid the problems associated with long | |
281 | commandlines under some shells. | |

682 | =head1 NAME | |
683 | ||
684 | ExtUtils::CBuilder::Platform::Windows - Builder class for Windows platforms | |
685 | ||
686 | =head1 DESCRIPTION | |
687 | ||
688 | This module implements the Windows-specific parts of ExtUtils::CBuilder. | |
689 | Most of the Windows-specific stuff has to do with compiling and | |
690 | linking C code. Currently we support the 3 compilers perl itself | |
691 | supports: MSVC, BCC, and GCC. | |
692 | ||
693 | This module inherits from C<ExtUtils::CBuilder::Base>, so any functionality | |
694 | not implemented here will be implemented there. The interfaces are | |
695 | defined by the L<ExtUtils::CBuilder> documentation. | |
