supports inline assembly. I thought the answer would be no though, as I has
checked if GCC supported inline asm and it looks like it does, but you need
to do some things before it's able to work. I didn't really read into detail
though. Anyway, that is fine. I can exclude the function.
I'll try to explain the header problem more throughly. You answered the
first part for me Matthias, thanks. I hadn't actually checked if it was in
another namespace (doh!), I was trying to find the correct syntax earlier
though. Can I do this for instance:
inlineASM = mb.namespace("foo").class_("NxMath").member_function("bar")
inlineASM.exclude()
Right now because of this function I can't generate any code at all. Here is
the error I get:

C:/Program Files/NVIDIA Corporation/NVIDIA PhysX
SDK/v2.8.1/SDKs/Foundation/include/NxMath.h: In
   static member function `static void NxMath::sinCos(float, NxF32&,
NxF32&)':
C:/Program Files/NVIDIA Corporation/NVIDIA PhysX
SDK/v2.8.1/SDKs/Foundation/include/NxMath.h:744: error: `
   _asm' undeclared (first use this function)
C:/Program Files/NVIDIA Corporation/NVIDIA PhysX
SDK/v2.8.1/SDKs/Foundation/include/NxMath.h:744: error: (Each
   undeclared identifier is reported only once for each function it appears
   in.)
C:/Program Files/NVIDIA Corporation/NVIDIA PhysX
SDK/v2.8.1/SDKs/Foundation/include/NxMath.h:744: error: syntax
   error before `local'

I get this error whether or not I exclude the function (the way I had shown
in the previous post). So I'm guess the problem is probably with namespaces
and gccxml can not find the function I'm giving it. Sorry if any of these
are silly questions. I'm still learning how to use py++ and I've never used
GCC before (I've always used Microsoft compilers). GCC surely has some
global define like WIN32 and LINUX to determine OS, does it not? I don't
think that's a problem though. At least I'm not getting any errors related
to it. The errors I posted are the only errors I'm getting at this point.
Hopefully I was a bit more clear this time :) - Tom
