Re: [pygame] controlled midi playback

Python 2.5 extensions are compiled on Windows with vctoolkit2003 by default. It is the same compiler used on Python 2.5. When I compile with MinGW I get these warnings: 

Warning: .drectve `-defaultlib:LIBCMT ' unrecognized
Warning: .drectve `-defaultlib:OLDNAMES ' unrecognized
Warning: .drectve `-defaultlib:uuid.lib ' unrecognized
Warning: .drectve `-defaultlib:uuid.lib ' unrecognized
Warning: .drectve `-defaultlib:LIBCMT ' unrecognized
Warning: .drectve `-defaultlib:OLDNAMES ' unrecognized

Warning: .drectve `-defaultlib:uuid.lib ' unrecognized
Warning: .drectve `-defaultlib:LIBCMT ' unrecognized
Warning: .drectve `-defaultlib:OLDNAMES ' unrecognized
which appear to be related to the libraries portmidi.lib and porttime.lib. Maybe the VC linker can ignore -defaultlib directives in a library. I find there is a /NODEFAULTLIB:library linker option. Maybe add something like the following to setup.py after libraries = [....] for win32:
extra_link_args=["NODEFAULTLIB:LIBCMT", "NODEFAULTLIB:OLDNAMES", "NODEFAULTLIB:uuid.lib"]
Or try running vcvars32.bat (is there one for the 2003 toolkit) before executing setup.py.
If you wish you may try the pypm.pyd I compiled MinGW. It links to msvcr71.dll, which is the big issue with Python 2.5, and works with my small test program.

that fixed the pyrex problem. i have the .c file now but there is another problem i ran into. i tried to use code::blocks and the vctoolkit2003 to compile the extension. i get this error message: fatal error LNK1104: cannot open file 'LIBCMTD.LIB' maybe you can give me another tip? what compiler did python 2.5 for windows get compiled with? i read somewhere that it can get messy if you don't use the same compiler for extensions.

    Yeah. To make Pyrex compatible with C++ enumerations are no longer
    treated as integers, though assignment of an enumeration to an
    integer
    is still allowd. Not accepting an enumeration as a boolean value
    may be
    a bug. I would have to check. But then again it makes some sense. Just
    edit line 357 to be:


           while(Pm_Poll(self.midi) != pmNoError):
