I'm debating when to move my own development machine to Leopard. Right now all the components that I use to assemble my Python app were built on 10.4, so I know they should run on both 10.4 and 10.5; I want to continue to support 10.4. However, will an application that is bundled by py2app on 10.5 run on 10.4 if all the frameworks were originallybuild on 10.4? Does py2app introduce any kind of additional compilationthat would break backward OS compatability?
py2app does not cause additional compilation. As long as the python framework and all extensions and shared libraries are build for 10.4 the resulting .app should work just fine.
In theory it should even be possible to build extensions on 10.5, as long as the python framework is build with the 10.4u SDK and MACOSX_DEPLOYMENT_TARGET is set to 10.4. That's not something I've tested though, just compiling all C/C++ code on a 10.4 system is therefore the safest course.
