Re: Hopelessly stuck with Boost.Python again

During the last hour I've build a release version of our app
containing Boost.Python. I hadn't done this before since it
required a lot of configuration changes - I had planned to use 
Python only in our debug version.

And....... it works! Finally!

So the problem with the unresolved external seems to appear
in only when using BOOST_DEBUG_PYTHON to compile the bp lib.

But why? I see that BOOST_DEBUG_PYTHON is only used in 
wrap_python.hpp to switch the python version. How can this
affect the compilation of conversions.obj and types.obj?
