Hello,

I'm trying to install Clang, using CMake with Ninja suport, according to this tutorial:

clang.llvm.org/docs/LibASTMatchersTutorial.html

The problem comes when building Clang. I uses this comand:

cmake .. -GNinja -DCMAKE_C_COMPILER=/path/to/clang -DCMAKE_CXX_COMPILER=/path/to/clang++Esto es lo que creo que finalmente he puesto:cmake -G Ninja ../llvm -DLLVM_BUILD_TESTS=ON -DCMAKE_C_COMPILER=/usr/local/bin/clang -DCMAKE_CXX_COMPILER=/usr/local/bin/clang++

instead of what the tutorial says by someone recommendation. But when I run Ninja (whith -v option) again i get this:

ninja: build stopped: subcommand failed.

Using locate c++config.h i get this directory, which is not where clang++ y searching for it:

/usr/include/i386-linux-gnu/c++/4.7/bits/c++config.h

I think it's because g++ look for it in a directory by default, by clang++ search for it in another location. How could I tell clang where to find it?

I'm using LinuxMint 15 32-bit.
