I'm with OSX Lion, compiling for backwards compability with 10.5 (even 10.4 compiles). I don't do any static libs/exes. Here is my script, which compiles for 386/x86_64 and merges them into one fat (universal) exe. I have to switch and compile with gcc-4.2 which is GNU GCC, not LLVM

I haven't downloaded yet the latest XCode 4.5 beta, here is what I got currently:

xcodebuild -version
Xcode 4.2
Build version 4D139

As I always do "cleaner" instead of clean, relying on lua installed already (in my case through MacPorts - "port install lua")

Hi,

I had a compilation error when compiling on the new OS X lion - it
boiled down to /usr/include/unwind.h being different than the standard
GCC version.

In particular, _Unwind_Exception_Class and _Unwind_Ptr, are not
declared, but where they are referenced previously, uint64_t and
uintptr_t are used instead. I've not done any form of extensive testing,
but the attached patch seems to suffice to make it compile.

I am not sure, but the preprocessor check for __llvm__ may need to be
stricter, in the sense that maybe llvm-gcc on linux probably uses the
standard GCC unwind.h.
