270 | |
271 | The packages below implement functions for generating properly |
3c4b39be |
272 | formatted commandlines for the compiler being used. Each package |
6b09c160 |
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 |
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. |

677 | =head1 NAME |
678 | |
679 | ExtUtils::CBuilder::Platform::Windows - Builder class for Windows platforms |
680 | |
681 | =head1 DESCRIPTION |
682 | |
683 | This module implements the Windows-specific parts of ExtUtils::CBuilder. |
684 | Most of the Windows-specific stuff has to do with compiling and |
685 | linking C code. Currently we support the 3 compilers perl itself |
686 | supports: MSVC, BCC, and GCC. |
687 | |
688 | This module inherits from C<ExtUtils::CBuilder::Base>, so any functionality |
689 | not implemented here will be implemented there. The interfaces are |
690 | defined by the L<ExtUtils::CBuilder> documentation. |
