In ccompiler, you have this code in gen_lib_options:
for lib in libraries: (lib_dir, lib_name) = os.path.split (lib) if lib_dir: lib_file = compiler.find_library_file ([lib_dir], lib_name) if lib_file: lib_opts.append (lib_file) else: compiler.warn ("no library file corresponding to " "'%s' found (skipping)" % lib) else: lib_opts.append (compiler.library_option (lib))
Note that you aren't passing "debug" to compiler.find_library_file, so the debug libraries will never get used. Also note that msvccompiler doesn't provide for passing the debug flag to library_option, so it doesn't do the proper name mangling (adding _d) for the library name. I'm guessing you'll need to make gen_lib_options get passed the debug flag, and then make it pass that flag on to the compiler methods. No clue what to do for non-vc++ compilers (or even if they need debug flags).
You are completely right: MSVCCompiler links with the wrong library on debug builds. I just tried and noticed that python15.lib is explicitely passed to the linker (for both debug and release builds) although this is completely unneccessary for MSVC, since the python import library is already set with in pragma in Python.h. Maybe you should try one of the older code snapshots (for a certain definition of 'old')... Thomas
