63 xsubpp - compiler to convert Perl XS code into C code
67 B<xsubpp> [B<-v>] [B<-except>] [B<-s pattern>] [B<-prototypes>] [B<-noversioncheck>] [B<-nolinenumbers>] [B<-nooptimize>] [B<-typemap typemap>] [B<-output filename>]... file.xs
71 This compiler is typically run by the makefiles created by L<ExtUtils::MakeMaker>
72 or by L<Module::Build> or other Perl module build tools.
74 I<xsubpp> will compile XS code into C code by embedding the constructs
75 necessary to let C functions manipulate Perl values and creates the glue
76 necessary to let Perl access those functions. The compiler uses typemaps to
77 determine how to map C function parameters and variables to Perl values.
79 The compiler will search for typemap files called I<typemap>. It will use
80 the following search path to find default typemaps, with the rightmost
81 typemap taking precedence.
83 ../../../typemap:../../typemap:../typemap:typemap
85 It will also use a default typemap installed as C<ExtUtils::typemap>.
89 Note that the C<XSOPT> MakeMaker option may be used to add these options to
90 any makefiles generated by MakeMaker.
96 Retains '::' in type names so that C++ hierarchical types can be mapped.
100 Adds exception handling stubs to the C code.
102 =item B<-typemap typemap>
104 Indicates that a user-supplied typemap should take precedence over the
105 default typemaps. This option may be used multiple times, with the last
106 typemap having the highest precedence.
108 =item B<-output filename>
110 Specifies the name of the output file to generate. If no file is
111 specified, output will be written to standard output.
115 Prints the I<xsubpp> version number to standard output, then exits.
119 By default I<xsubpp> will not automatically generate prototype code for
120 all xsubs. This flag will enable prototypes.
122 =item B<-noversioncheck>
124 Disables the run time test that determines if the object file (derived
125 from the C<.xs> file) and the C<.pm> files have the same version
128 =item B<-nolinenumbers>
130 Prevents the inclusion of `#line' directives in the output.
134 Disables certain optimizations. The only optimization that is currently
135 affected is the use of I<target>s by the output C code (see L<perlguts>).
136 This may significantly slow down the generated code, but this is the way
137 B<xsubpp> of 5.005 and earlier operated.
141 Disable recognition of C<IN>, C<OUT_LIST> and C<INOUT_LIST> declarations.
145 Disable recognition of ANSI-like descriptions of function signature.
149 Currently doesn't do anything at all. This flag has been a no-op for
150 many versions of perl, at least as far back as perl5.003_07. It's
151 allowed here for backwards compatibility.
157 No environment variables are used.
