Re: cmake error on Ubuntu 13.10

[Fred Kiefer]

I don't know anything about building clang/llvm and you seem to be stuck
in that stage. From comparing the wiki page and your command lines I see
a little difference. You try to build the llvm tools separately on the
Wiki this happens as part of building llvm:

cd ~/llvm
mkdir build
cd build
cmake ..
make -j8   # 8=your number of build CPUs

What is the result of doing it the documented way?
