Re: How to use boost.python

I tried to compile boost.python 1.20.2 with KCC4.0e on linux7.1.
Libary compilation seems fine and libboost_python.a was created. But
when I tried to compile test programs, it gives me errors. I tried two
programs, comprehensive.cpp in ./test directory and abstract.cpp in
./example directory, both gave me errors.

*************comprehensive.cpp*************

Since KCC usually takes two step to compile a template-rich program, I
doubt it really finished libary compiling. The errors it complained
are in extension_class.o. Are idea what is wrong? thanks.
