[cfe-dev] [3.5 Release] <cxxabi.h> not found by clang-3.5 rc1 with libc++

[Marc J. Driftmeyer]

This has been broken on Linux [Debian Linux in my case], as in it has 
never worked on Linux that I've tested, but it magically works [for 
obvious reasons] on OS X.

Debian has LLVM/Clang 3.4.2 with /usr/include/c++/v1/

Building from trunk having /usr/local/include/c++/v1

Both are broken.

I don't even bother building trunk with the following turned on:

//Use libc++ if available.
LLVM_ENABLE_LIBCXX:BOOL=ON

I default to the following:

//Use libc++ if available.
LLVM_ENABLE_LIBCXX:BOOL=OFF

Otherwise, the damn stack won't compile. By off it just defaults to 
GCC's libstc++ stack and compiles as expected. Everything else with 
compiling a fresh libc++ builds when turned on in cmake, but this part.
