[PD] Building Pd App on OSX

[Dan Wilcox]

Wee. You're lucky I just did a bunch of low level library compiling stuff on OSX/iOS for OpenFrameworks ...

By specifying multiple architectures, OSX will build a "fat" lib that supports them in a single binary.

i386 + ppc is the old "universal binary/lib". The new 10.7+ format is i386 + x86_64 so I'd suggest dropping the old format
now as the vast majority of people are using newer Intel machines.

sysroot should point to the Mac OSX SDK location. For newer Xcodes, there is a commandline util that returns the path to the Xcode
developer root: xcode-select -print-path. With Xcode 4.6, it returns:

/Applications/Xcode.app/Contents/Developer

For example, with the 10.8 SDK you can use this:
$(xcode-select -print-path)/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.8.sdk/

Naturally, you can do a search in that SDKs folder and choose the last one to build for the latest SDK or simply use a shell variable:

OSX_SDK_VER=10.8
SYSROOT=$(xcode-select -print-path)/Platforms/MacOSX.platform/Developer/SDKs/MacOSX$OSX_SDK_VER.sdk/

Yes, it contains all of the includes and libs for that particular SDK.

gcc should be fine for now, you could target llvm-gcc if you want, but gcc isn't disappearing complete in the meantime.
