XS cannot properly handle typemap with namespace

llancet has asked for the wisdom of the Perl Monks concerning the following question:

I'm trying to write a perl wrapper for my C++ library. My whole library is under a namespace:

namespace geno_eye
{
typedef int64_t PosType;
}
[download]

I wrote the following typemap, in which T_IV is a perl build-in typemap:

TYPEMAP
geno_eye::PosType    T_IV
[download]

and I wrote the following XS code:

....

MODULE = GenoEye        PACKAGE = GenoEye::Page

geno_eye::Page*
Page::new(format, file, width, height, genome_display_length)
    SV* format
    SV* file
    double width
    double height
    geno_eye::PosType genome_display_length
    CODE:
[download]

It seems xsubpp converts ":" into "_":

GenoEye.c:196:2: error: ‘geno_eye__PosType’ was not declared in this s
+cope
  geno_eye__PosType genome_display_length = (geno_eye__PosType)SvIV(ST
+(5))
[download]

How to work around it?

It seems XSpp is another system that is completely different with XS. So I'll have to suffer another painful learning......	[reply]
