Summary: distutils cannot link C++ code with GCC

Initial Comment:
It is mandatory to link C++ code against -lstdc++ -lm 
when creating an extension.

distutils does not do this in 2.1.1

Here is a setup.py for Python CXX that works around 
the problem, but it would be better for distutils to 
understand enough about C++ to do the right thing. 
THen the code for other compilers could be added. But 
GCC is important enough to do first.

You can get the CXX sources from
http://sourceforge.net/projects/cxx/

from distutils.core import setup, Extension

if os.name == 'posix':
	CXX_libraries = ['stdc++','m']
else:
	CXX_libraries = []


setup(name="pycxx_demo", version="1.0",
	ext_modules=
		[Extension(
			"example",
			sources = [
				"Demo/example.cxx",
				"Demo/python.cxx",
				"Demo/range.cxx",
				"Demo/rangetest.cxx",
			
	"Src/cxx_extensions.cxx",
				"Src/cxxextensions.c",
				"Src/cxxsupport.cxx",
			
	"Src/IndirectPythonInterface.cxx" ],
			include_dirs = [ ".", "Demo" ],
			libraries = CXX_libraries
			)
		]
	)

Barry, is this still a problem w/2.2.2?

Yes using G++ is another way to solve this.

Is this the same problem as

[ #413582 ] g++ must be called for c++ extensions

?  Not a rhetorical question, I would like to know!

Nobody at PL understands distutils well enough to do this,
so lowering the priority -- there's no way this will hold up
the release.
