[Pythonmac-SIG] configure/distutils and C++

[Doug Wyatt]

I thought I'd rephrase and summarize what I learned trying to build 
XIST, which uses distutils and has one .cxx file.

What I learned: distutils gets its information about the compile/link 
commands from configure; a copy of the Python Makefile gets stored in 
/usr/local/lib/python2.2/config/Makefile.

configure --with-cxx=g++ does cause g++ to get invoked to compile .cxx 
or .cpp (etc.) sources, but the problem appears to be that:
[a] at least on Mac OS X, that's unneccessary; gcc will "do the right 
thing" for C++ sources
[b] there is no way to generate different link commands depending on 
whether one of the source files was C++.  The general solution might be 
simply to define -lstdc++ for all link commands in configure, and rely 
on the linker being smart enough to notice that nothing from libstdc++ 
is referenced when there are no C++ files compiled.

Have I missed something about distutils/configure?
