[pygame] Re: Mac OS X MIDI support success (MacPorts)

[Russell Owen <rowen@xxxxxx>]

The problem I'm having is that it insists on trying to use Mac OS X 10.5 SDK, which doesn't even exist on my operating system (I'm trying to build this on Mac OS X 10.4, to assure backward compatibility, and I only have 10.3.9 and 10.4 SDKs installed). That's clearly not going to work.

I have tried everything I can think of, based on google searches, including:
$ export MACOSX_DEPLOYMENT_TARGET=10.4
$ export CMAKE_OSX_DEPLOYMENT_TARGET=10.4
$ export CMAKE_OSX_SYSROOT=/Developer/SDKs/MacOSX10.4.sdk
and even running the CMake GUI and overriding the path to the SDK before pressing Generate. It ignores everying and always uses a path to the nonexistent 10.5 SDK.

I don't know if this is a bug in CMake 2.8.6 or if portmidi's config insists on 10.5 or later.

It's presumably practical to build a binary installer for python.org's 64-bit python (Mac OS X 10.6 and later) that includes portmidi. I'm not sure it's doable for the 32-bit python.org python (MacOS X 10.3.9 and later) -- at least not without giving up 10.4 compatibility.
