I will answer here, would you mind to upload the answer to stackoverflow?

I use bjam only to compile boost. After this, I prefer to use scons ( on Windows and on Linux ). The following is an example of sconstruct file, which is used to compile one of the Py++ unittests: ( this is a generated code too :-) ) import sys env = Environment() if 'linux' not in sys.platform: env['MSVS'] = {'VERSION': ''} env['MSVS_VERSION'] = '' Tool('msvc')(env) t = env.SharedLibrary( target=r'abstract_classes' , source=[ r'/home/roman/language-binding/sources/pyplusplus_dev/unittests/temp/abstract_classes.cpp' ] , LIBS=[ r"boost_python" ] , LIBPATH=[ r"",r"/home/roman/include/libs" ] , CPPPATH=[ r"/home/roman/boost_svn",r"/usr/include/python2.6",r"/home/roman/language-binding/sources/pyplusplus_dev/unittests/temp",r"/home/roman/language-binding/sources/pyplusplus_dev/unittests/data",r"/home/roman/boost_svn" ] , CCFLAGS=[ ] , SHLIBPREFIX='' , SHLIBSUFFIX='.so' ) Since your code generator written in Python, you can continue where Py++ stops and generate your favorite "make" file. You can go even father. Py++ tests generate the code, compile, load new module and test the functionality. All this is done in a single, stand alone process.
