Creating a DLL from a wrapped cpp file with SWIG

Question

I am in the process of learning how to use SWIG on Windows.

The following is my c++ code:

 /* File : example.cxx */

 #include \"example.h\"
 #defin         


        

Answer 1

SWIG (at least on v3.0) generates the python.h inclusion in the wrapper as follows:

#if defined(_DEBUG) && defined(SWIG_PYTHON_INTERPRETER_NO_DEBUG)
/* Use debug wrappers with the Python release dll */
# undef _DEBUG
# include 
# define _DEBUG
#else
# include 
#endif

So when compiling a debug version of the wrapper on a Windows platform, we simply need to define the SWIG_PYTHON_INTERPRETER_NO_DEBUG flag to avoid the pyconfig.h file issue mentioned in Ken's answer.
