smake 1.2.1 fails to build using Xcode 4.2

[macports@…]

Building smake 1.2.1 after upgrading to Xcode 4.2 hangs at the same position. The OBJ/i386-darwin-cc/avoffset process uses 100% CPU when this happens.

Hi,

I'm hitting the same issue. Any idea how to work around it ?

[macports@…]

I finally got this port to build by using the "-vv" flag. Perhaps this turns off parallel compilation? Maybe I was just lucky though.

It's building with 'gcc' which ends up being llvm-gcc-4.2 with Xcode 4.x. Using clang instead seems to make it work. r91666

Actually, clang seems to have the same problem in older Xcode versions -- 4.3 is OK, 4.1 is not, 4.2 I don't have handy. Guess we'll just have to fall back to gcc 4.2. r91667

If anyone finds a better solution, or if this works with the clang in Xcode 4.2, please let us know of course.
