Hi Marshall, I'm trying to compile the whole thing in one go by adding libcxx and libcxxabi into llvm/src/projects. The first stage obviously has to use the system compiler, which is GCC 4.8.2, but I'm getting an error on ARM: Unwind-EHABI.cpp:1000:47: error: expected unqualified-id before string constant _LIBUNWIND_EXPORT extern "C" _Unwind_Reason_Code with the caret pointing at _Unwind_Reason_Code. With Clang, it passes, as it's what I'm using on the libcxx ARM buildbot. I tried using -std=c++11 on CXXFLAGS, but didn't seem to have made a difference. Ideas? cheers, --renato PS: I have other problems with AArch64, but let's deal with this one first. :)

You can play around with: __attribute__((visibility("default"))) extern "C" void func() {} Cheers. Tim.
