Re: [boost] Import problem

I downloaded the boost_jam rpms and did a make in a new directory after doing a "make links" with gcc resolving to gcc3.02. The make test passed with no problem. So as far as I know, my .so and my libbboost_python.a are both compiled with gcc3.02. I have symlinked the defs of gcc and g++ to achieve this. Do I need to symlink ld as well? I am running 2.11.90.0.8.

Also, is there a way to examine my libboost_python.a and confirm it was built with gcc3?

Thanks so much for your help.
