Each package defines two primary functions 'format_linker_cmd()' & 'format_compiler_cmd()' that accepts a list of named arguments (a hash) and returns a list of formatted options suitable for invoking the compiler. By default, if the compiler supports scripting of its operation then a script file is built containing the options while those options are removed from the commandline, and a reference to the script is pushed onto the commandline in their place. Scripting the compiler in this way helps to avoid the problems associated with long commandlines under some shells. =end comment =cut sub new { my $class = shift; my $self = $class->SUPER::new(@_); my $cf = $self->{config}; # Inherit from an appropriate compiler driver class my $driver = "ExtUtils::CBuilder::Platform::Windows::" . $self->_compiler_type; eval "require $driver" or die "Could not load compiler driver: $@"; unshift @ISA, $driver; return $self; } sub _compiler_type { my $self = shift; my $cc = $self->{config}{cc}; return ( $cc =~ /cl(\.exe)?$/ ?

Most of the Windows-specific stuff has to do with compiling and linking C code. Currently we support the 3 compilers perl itself supports: MSVC, BCC, and GCC. This module inherits from C, so any functionality not implemented here will be implemented there. The interfaces are defined by the L documentation. =head1 AUTHOR Ken Williams Most of the code here was written by Randy W.
