xsubpp - compiler to convert Perl XS code into C code
SYNOPSIS
xsubpp [-v] [-except] [-s pattern] [-prototypes] [-noversioncheck] [-nolinenumbers] [-nooptimize] [-typemap typemap] [-output filename]...
file.xs
DESCRIPTION
This compiler is typically run by the makefiles created by ExtUtils::MakeMaker.
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 typemap. It will use the following search path to find default typemaps, with the right-
most typemap taking precedence.
../../../typemap:../../typemap:../typemap:typemap
It will also use a default typemap installed as "ExtUtils::typemap".
OPTIONS
Note that the "XSOPT" MakeMaker option may be used to add these options to any makefiles generated by MakeMaker.
-hiertype
Retains '::' in type names so that C++ hierarchical types can be mapped.
-except
Adds exception handling stubs to the C code.
-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.
-output filename
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.
-prototypes
By default xsubpp will not automatically generate prototype code for all xsubs. This flag will enable prototypes.
-noversioncheck
Disables the run time test that determines if the object file (derived from the ".xs" file) and the ".pm" files have the same version
number.
-nolinenumbers
Prevents the inclusion of `#line' directives in the output.
-nooptimize
Disables certain optimizations. The only optimization that is currently affected is the use of targets by the output C code (see
perlguts). This may significantly slow down the generated code, but this is the way xsubpp of 5.005 and earlier operated.
-noinout
Disable recognition of "IN", "OUT_LIST" and "INOUT_LIST" declarations.
-noargtypes
Disable recognition of ANSI-like descriptions of function signature.
-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.
ENVIRONMENT
No environment variables are used.
