I<xsubpp> will compile XS code into C code by embedding the constructs necessary to let C functions manipulate Perl values and creates the glue necessary to let Perl access those functions. The compiler uses typemaps to determine how to map C function parameters and variables to Perl values. The compiler will search for typemap files called I<typemap>. It will use the following search path to find default typemaps, with the rightmost typemap taking precedence. ../../../typemap:../../typemap:../typemap:typemap It will also use a default typemap installed as C<ExtUtils::typemap>. =head1 OPTIONS Note that the C<XSOPT> MakeMaker option may be used to add these options to any makefiles generated by MakeMaker. =over 5 =item B<-hiertype> Retains '::' in type names so that C++ hierarchical types can be mapped. =item B<-except> Adds exception handling stubs to the C code. =item B<-typemap typemap> Indicates that a user-supplied typemap should take precedence over the default typemaps. This option may be used multiple times, with the last typemap having the highest precedence. =item B<-output filename> Specifies the name of the output file to generate. If no file is specified, output will be written to standard output. =item B<-v> Prints the I<xsubpp> version number to standard output, then exits. =item B<-prototypes> By default I<xsubpp> will not automatically generate prototype code for all xsubs. This flag will enable prototypes. =item B<-noversioncheck> Disables the run time test that determines if the object file (derived from the C<.xs> file) and the C<.pm> files have the same version number. =item B<-nolinenumbers> Prevents the inclusion of '#line' directives in the output. =item B<-nooptimize> Disables certain optimizations. The only optimization that is currently affected is the use of I<target>s by the output C code (see L<perlguts>). This may significantly slow down the generated code, but this is the way B<xsubpp> of 5.005 and earlier operated. =item B<-noinout> Disable recognition of C<IN>, C<OUT_LIST> and C<INOUT_LIST> declarations. =item B<-noargtypes> Disable recognition of ANSI-like descriptions of function signature. =item B<-C++> Currently doesn't do anything at all. This flag has been a no-op for many versions of perl, at least as far back as perl5.003_07. It's allowed here for backwards compatibility. =item B<-s=...> or B<-strip=...> I<This option is obscure and discouraged.> If specified, the given string will be stripped off from the beginning of the C function name in the generated XS functions (if it starts with that prefix). This only applies to XSUBs without C<CODE> or C<PPCODE> blocks. For example, the XS: void foo_bar(int i); when C<xsubpp> is invoked with C<-s foo_> will install a C<foo_bar> function in Perl, but really call C<bar(i)> in C. Most of the time, this is the opposite of what you want and failure modes are somewhat obscure, so please avoid this option where possible. =back =head1 ENVIRONMENT No environment variables are used. =head1 AUTHOR Originally by Larry Wall.
