[Swig-user] error compiling a wrapped c++ file

[Ingo B. <ing...@we...>]

Hello,

I have the latest SWIG and Python versions and I tried to wrap a simple c (c++) example with swig but without success:

 example.c

 int fun(int x, int y) {
   int g;
   g = x + y;
   return g;
 }

 example.i

 %module example.i
 extern int fun(int x, int y);

 1.) swig -python -c++ example.i

 => example_wrapper.cxx

 2.) gcc -c -fpic example_wrapper.cxx -I/python/include -I/....... all  the include paths

 THIS DOES NOT WORK, BUT PRODUCING THE MESSAGES
