Error building libc++ with clang - MacOSX 10.6

Clang Frontend
1

Dear all,

I’m currently attempting to build a self-hosted clang / LLVM toolset. The initial build of clang / LLVM with GCC has been successful (and clang is currently building itself, all good so far), I’m now wanting to build libc++ with clang (in order to then re-build clang with itself and a self-hosted libc++), however following the simple instructions on the lib++ index page, I’m getting the error “‘cxxabi.h’ file not found” shown below [1].

I’ve found one mailing list post mentioning this [2], but not proposing how to work around it. I’d welcome any suggestions.

Yours,
James.

Hello,

I'm currently attempting to build a self-hosted clang / LLVM toolset. The initial build of clang / LLVM with GCC has been successful (and clang is currently building itself, all good so far), I'm now wanting to build libc++ with clang (in order to then re-build clang with itself and a self-hosted libc++), however following the simple instructions on the lib++ index page, I'm getting the error "'cxxabi.h' file not found" shown below [1].

You need this file from libc++abi: <http://llvm.org/svn/llvm-project/libcxxabi/trunk/include/cxxabi.h&gt;

HTH,
Jonathan
