I had tried already without ccache (and a clean build directory). What I hadn't tried though was not defining CXX and CC variables to LLVM. Surprisingly, I am able to compile the viewer now despite the deceptive message that autobuild is now using Clang. The confusing thing is that I can point the CXX and CC variables to the exact same compilers xcode is using and still get the exact same failure. This sort of behaviour leaves me a little miffed. Being that I would really like to use ccache in my work, would you happen to know of a way to tell xcode to use ccache + llvm in Second life's compilation process? > (just won't work on Xcode5, which you aren't using anyway, because Apple > symlinked "llvm-gcc" to clang. -_-) So, one could get xcode5 working by just changing the symlink to the right compiler?
