- PPC iBooks don't support booting from USB, good luck reinstalling a OS when your internal drive breaks
- everything earlier then MacOSX 10.4 Tiger seems completely unusable by now, as almost all software won't run on it, no support for building universal binaries either, OSX seems to go obsolete a lot faster then Windows
- MacPorts provides a good and up to date selection of software, you can almost find anything that you might need to build your software there, but MacPorts requires to compile everything from source, so installing a full build environment can take quite a few hours
- Flink provides binaries, but is outdated enough to be of not much use
- some include directives need changes, for example GL/gl.h to OpenGL/gl.h, AL/al.h to OpenAL/al.h
- native MacOSX libraries come in the form of frameworks, which bypass the usual -I, -l and -L flags and use a "-framework SDL" flag for gcc
- SDL comes as a native precompiled OSX framework library
- using the SDL framework requires to hardcode the include path or doing #ifdef's, as there is no sdl-config and the way frameworks requires you to include SDL_image with
, which is incompatible with the way things are done in Linux
- using g++ with -isystem DIR instead of -IDIR results in "error: template with C linkage", so don't do that on older MacOSXs
- otool is the equivalent of ldd on MacOSX
- building a standard MacOSX software bundle requires some fudging with the hard compiled path variables
- Gtk+ is by far the most troublesome piece of software to get up and running, it doesn't come in binary form but only in a fragile jhbuild
- MacOSX specific code can be isolated with a #ifdef __APPLE__ or on the Python side with a sys.platform == "darwin"
PS: While porting Windstille over to MacOSX I also fixed a few issues with the render path for older hardware, so it should be able to run (or crawl) again on Geforce2MX style hardware.
