244 | |
245 | The packages below implement functions for generating properly |
3c4b39be |
246 | formatted commandlines for the compiler being used. Each package |
6b09c160 |
247 | defines two primary functions 'format_linker_cmd()' & |
248 | 'format_compiler_cmd()' that accepts a list of named arguments (a |
3c4b39be |
249 | hash) and returns a list of formatted options suitable for invoking the |
6b09c160 |
250 | compiler. By default, if the compiler supports scripting of its |
251 | operation then a script file is built containing the options while |
252 | those options are removed from the commandline, and a reference to the |
253 | script is pushed onto the commandline in their place. Scripting the |
254 | compiler in this way helps to avoid the problems associated with long |
255 | commandlines under some shells. |

659 | =head1 NAME |
660 | |
661 | ExtUtils::CBuilder::Platform::Windows - Builder class for Windows platforms |
662 | |
663 | =head1 DESCRIPTION |
664 | |
665 | This module implements the Windows-specific parts of ExtUtils::CBuilder. |
666 | Most of the Windows-specific stuff has to do with compiling and |
667 | linking C code. Currently we support the 3 compilers perl itself |
668 | supports: MSVC, BCC, and GCC. |
669 | |
670 | This module inherits from C<ExtUtils::CBuilder::Base>, so any functionality |
671 | not implemented here will be implemented there. The interfaces are |
672 | defined by the L<ExtUtils::CBuilder> documentation. |
