Re: [pygame] Re: Pygame midiout not working...

Hey folks,

I was wondering if the Mac midi output issue has been resolved.

Any word on a new build?

hrmm.  It seems the xcode 4.2 installer moved some stuff into "/Developer-old" folder and the ppc compilers are still in there.  So maybe that will work.  I'll give it a go later.

Also, this is the guide I plan to use for ppc support on Lion.

It's a bit hard for me, since I'm on OSX Lion and xcode 4.2 now.  Apple removed PPC support in their compiler here.  Which means PPC support is impossible without installing xcode 3 too.  So I need to install xcode 3 first to a separate directory, then install xcode 4.2 again, then do some symlinking in order to get them both working.

Note, to see the architectures in a dylib
    lipo -info /usr/local/lib/libportmidi.dylib

To remove the x64 architecture, and create a new version in /tmp/:
    lipo /usr/local/lib/libportmidi.dylib -remove x86_64 -output /tmp/libportmidi.dylib

Then to see what it is linked against...
    otool -L /usr/local/lib/libportmidi.dylib

So far I've had no luck building portmidi--either the current release or the trunk you provided. I get tons of errors that suggest fundamental .h files aren't being found. (And yes, I do have CMake installed and running). I suspect this is because the xcode project file was saved with too recent a version of xcode (as it reports when I open it in XCode).

Also, it has no PPC target (based on opening the project on my main 10.6.8 machine). That will cause trouble with python.org's 32-bit python. I don't use xcode so I'm not sure how easy it would be to add a PPC target. Another option is to try an older version of portmidi, though I doubt users who rely on portmidi would want to go too far back.

If somebody wants to provide me a 32-bit intel+PPC static portmidi library, compatible with 10.4 and later, I'll use it. Or you can try more complete instructions (including minimum version of XCode and MacOS X on which to attempt the build) and I'll see if I can find time to go that route.
