Re: Types are unknown

Sorry, maybe I told you not enough details.

The developers of OpenSG defined their own types, for this they used the
standardtypes from c++. All does typedefs are in the file OSGBaseTypes.h.
For everything I want to do, in OpenSG, with types, I need to include
this file. I included the OSGBaseTypes.h like you discribed:
%{
#include "OSGBaseTypes.h"
%}

If I now use a function of the Vector-class there is a error like this:
ERROR: In procedureR64VecStorage4-setValues:
ERROR:  Wrong type argument in position 2: 3.3   
 
R64VecStorage4 is a container for a vector with 4 values of type Real64,
which is a double in c++. Every compilation works with no errors, but
guile doesn't know the OpenSG-types. So, if I write "#define Real64
double" in *.i or *_wrap.cpp, then guile knows the types, but I don't
want to do this for every file in the OpenSG-library. I thought there is a
better way to do this, but I don't know it.                                     
  
I have to tell guile, what the OpenSG-types are in c++.
I hope it is more clear now, what my problem looks like.
Thanks a lot!
