Inline::CPP on win32 bug

hey all..

I was trying to build Inline:CPP on win32 using visualc++ version 6, and got
the following error in testing:

C:\visualc\VC98\INCLUDE\math.h(514) : error C2894: templates cannot be
declared to have 'C' linkage

NMAKE: fatal error U1077: 'cl' return code '0x2'.

I was wondering if this was a known bug (version .25 of Inline::CPP, because
it is a fatal error in using Inline::CPP on that platform..

Hmm.

I think the problem is that "perl.h" is included in an 'extern C' block,
which then includes math.h, which has template code.

If I comment out the template code in the main header included with vc++(
math.h), things seem to work fine. Of course this is totally backwards -
would it be possible to move the "perl.h" out of the "extern C" block
instead?

Yes, I think so. CPP.pm's sub validate() contains the following:

$o->{ILSM}{AUTO_INCLUDE} ||= <<END;
#ifndef bool
#include <%iostream%>
#endif
extern "C" {
#include "EXTERN.h"
#include "perl.h"
#include "XSUB.h"
#include "INLINE.h"
}
#ifdef bool
#undef bool
#include <%iostream%>
#endif
END

Try rewriting that to suit your needs.

Cheers,
