Forget gcc. Apple stopped updating it at 4.2.3. And their LLVM-backed GCC is extremely buggy[*]. The future on Mac goes through Clang. Yes, I understand that means losing support for some older versions of Mac OS X (definitely 10.5, maybe even 10.6 -- I'm not the expert). That's the only reason we're still supporting GCC on Mac at all, because some people still need it for older Macs. But we can't keep it up forever. [*] for example, the assembly code required to detect the CPU features on x86 simply doesn't compile correctly, so I've turned it off and made Qt always report the base CPU features. That means the enhanced draw helpers will be built into QtGui but never used. You're carrying dead code if you use GCC 4.2.3. -- Thiago Macieira - thiago.macieira (AT) intel.com Software Architect - Intel Open Source Technology Center
