.TH XSUBPP 1 "2007-06-19" "perl v5.8.8" "Perl Programmers Reference Guide"
xsubpp \- compiler to convert Perl XS code into C code
\&\fBxsubpp\fR [\fB\-v\fR] [\fB\-\*(C+\fR] [\fB\-csuffix csuffix\fR] [\fB\-except\fR] [\fB\-s pattern\fR] [\fB\-prototypes\fR] [\fB\-noversioncheck\fR] [\fB\-nolinenumbers\fR] [\fB\-nooptimize\fR] [\fB\-typemap typemap\fR] ... file.xs
This compiler is typically run by the makefiles created by ExtUtils::MakeMaker.
\&\fIxsubpp\fR will compile \s-1XS\s0 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 \fItypemap\fR. It will use
the following search path to find default typemaps, with the rightmost
typemap taking precedence.
\& ../../../typemap:../../typemap:../typemap:typemap
Note that the \f(CW\*(C`XSOPT\*(C'\fR MakeMaker option may be used to add these options to
any makefiles generated by MakeMaker.
Adds ``extern \*(L"C\*(R"'' to the C code.
.IP "\fB\-csuffix csuffix\fR" 5
.IX Item "-csuffix csuffix"
Set the suffix used for the generated C or \*(C+ code. Defaults to '.c'
(even with \fB\-\*(C+\fR), but some platforms might want to have e.g. '.cpp'.
Don't forget the '.' from the front.
Retains '::' in type names so that \*(C+ hierachical types can be mapped.
Adds exception handling stubs to the C code.
.IP "\fB\-typemap typemap\fR" 5
.IX Item "-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.
Prints the \fIxsubpp\fR version number to standard output, then exits.
.IP "\fB\-prototypes\fR" 5
By default \fIxsubpp\fR will not automatically generate prototype code for
all xsubs. This flag will enable prototypes.
.IP "\fB\-noversioncheck\fR" 5
.IX Item "-noversioncheck"
Disables the run time test that determines if the object file (derived
from the \f(CW\*(C`.xs\*(C'\fR file) and the \f(CW\*(C`.pm\*(C'\fR files have the same version
.IP "\fB\-nolinenumbers\fR" 5
.IX Item "-nolinenumbers"
Prevents the inclusion of `#line' directives in the output.
.IP "\fB\-nooptimize\fR" 5
Disables certain optimizations. The only optimization that is currently
affected is the use of \fItarget\fRs by the output C code (see perlguts).
This may significantly slow down the generated code, but this is the way
\&\fBxsubpp\fR of 5.005 and earlier operated.
Disable recognition of \f(CW\*(C`IN\*(C'\fR, \f(CW\*(C`OUT_LIST\*(C'\fR and \f(CW\*(C`INOUT_LIST\*(C'\fR declarations.
.IP "\fB\-noargtypes\fR" 5
Disable recognition of ANSI-like descriptions of function signature.
No environment variables are used.
