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. > * Why is there -isysroot?

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/ > * Any hint what -isysroot should be to find something as > common as stdlib.h? Yes, it contains all of the includes and libs for that particular SDK. > * Is "make -f makefile.mac" supposed to compile using cc, gcc, or something > else? gcc should be fine for now, you could target llvm-gcc if you want, but gcc isn't disappearing complete in the meantime. -------- Dan Wilcox @danomatika danomatika.com robotcowboy.com
