This compiler is typically run by the makefiles created by
ExtUtils::MakeMaker or by Module::Build or other Perl module build
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
The compiler will search for typemap files called typemap. It will use
the following search path to find default typemaps, with the rightmost
typemap taking precedence.
It will also use a default typemap installed as "ExtUtils::typemap".
Note that the "XSOPT" MakeMaker option may be used to add these options
to any makefiles generated by MakeMaker.
Retains '::' in type names so that C++ hierarchical types can be
Adds exception handling stubs to the C code.
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.
Specifies the name of the output file to generate. If no file is
specified, output will be written to standard output.
-v Prints the xsubpp version number to standard output, then exits.
By default xsubpp will not automatically generate prototype code
for all xsubs. This flag will enable prototypes.
Disables the run time test that determines if the object file
(derived from the ".xs" file) and the ".pm" files have the same
Disable recognition of "IN", "OUT_LIST" and "INOUT_LIST"
Disable recognition of ANSI-like descriptions of function
-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.
No environment variables are used.
