[cfe-dev] Failure building clang on Mageia2

[Edward Diener]

My attempt to build clang on Mageia2 from the latest llvm/clang source
failed when it could not find cxxabi.h. On Mageia2 it is at:

/usr/lib/gcc/x86_64-mageia-linux-gnu/4.6.3/include/

Here is the output with the compiler -v flag temporarily turned on:

I do not know why those gcc paths the compiler is searching are so
strange, but thet are clearly not where the file exists. Does anybody
have any idea ? The gcc compiler is 4.6.3.
