261 | ||
262 | The packages below implement functions for generating properly | |
3c4b39be | 263 | formatted commandlines for the compiler being used. Each package |
6b09c160 YST |
264 | defines two primary functions 'format_linker_cmd()' & |
265 | 'format_compiler_cmd()' that accepts a list of named arguments (a | |
3c4b39be | 266 | hash) and returns a list of formatted options suitable for invoking the |
6b09c160 YST |
267 | compiler. By default, if the compiler supports scripting of its |
268 | operation then a script file is built containing the options while | |
269 | those options are removed from the commandline, and a reference to the | |
270 | script is pushed onto the commandline in their place. Scripting the | |
271 | compiler in this way helps to avoid the problems associated with long | |
272 | commandlines under some shells. | |

669 | =head1 NAME | |
670 | ||
671 | ExtUtils::CBuilder::Platform::Windows - Builder class for Windows platforms | |
672 | ||
673 | =head1 DESCRIPTION | |
674 | ||
675 | This module implements the Windows-specific parts of ExtUtils::CBuilder. | |
676 | Most of the Windows-specific stuff has to do with compiling and | |
677 | linking C code. Currently we support the 3 compilers perl itself | |
678 | supports: MSVC, BCC, and GCC. | |
679 | ||
680 | This module inherits from C<ExtUtils::CBuilder::Base>, so any functionality | |
681 | not implemented here will be implemented there. The interfaces are | |
682 | defined by the L<ExtUtils::CBuilder> documentation. | |
