Problem w/ boost_python_debug.dll

[Boost.Python questions should go to the C++-sig
(http://www.python.org/sigs/c++-sig/); I seldom watch this list carefully.]


This is a limitation of our build system (sorry, we're working on it).
boost_python_pydebug.lib is really built as boost_python.lib, then
copied/renamed, a strategy that doesn't work out well. You have several
options:

    1. rename the debug products back to boost_python.lib/.dll, and link
with that. Keep debug and release versions in separate directories. Keep
your PATH straight so that the wrong one is never loaded by mistake

    2. Use Boost.Build to build your project. It always keeps the
debug/release/debug-python versions in separate directories, and
automatically points at the right one (which is why this doesn't cause me
all kinds of pain every day).

    3. Temporarily edit libs/python/build/Jamfile to change the name of the
library target from boost_python to boost_python_pydebug. Rebuild
everything. There will be a properly-named-and-functioning debug library in
the bin/ directory tree. Grab it and away you go.

Sorry for the inconvenience. I'm going to try to get distutils going for v2;
that should make some of these things easier.

HTH,
Dave
