[LLVMdev] Compiling LibC++ with LLVM on ARM (original) (raw)

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. :)
