[C++-sig] Re: Newbie vector_indexing_suite Link Errors

[David Brownell]

I was attempting to compile and link vector_indexing_suite.cpp, located in
the python\test directory.  It looks like #define'ing
BOOST_PYTHON_STATIC_LIB was all I needed.  Seems strange that I didn't have
to #define this until I started working with the vector_indexing_suite.

Thanks for your help!
