Description Yuta SATOH 2017-01-31 10:26:18 UTC

can not compile itself using clang++-4.0 + libcxx.
I confirmed this issue on both Linux and FreeBSD.


Steps to Reproduce:
1. USE="-doc libcxx" emerge sys-devel/clang sys-devel/clang-runtime sys-libs/compiler-rt-sanitizers sys-libs/libcxx sys-libs/compiler-rt sys-libs/libomp sys-devel/llvm (build with gcc)
2. CC=clang CXX="clang++ -stdlib=libc++" USE="-doc libcxx" emerge sys-devel/clang

Could you paste a full run-through of package versions? I'm particular interested in libcxx* version used.

The version of all packages except sys-libs/libcxxrt is 4.0.0_rc1.

# USE="-doc libcxx" emerge -pv sys-devel/clang sys-devel/clang-runtime sys-libs/compiler-rt-sanitizers sys-libs/libcxx sys-libs/compiler-rt sys-libs/libomp sys-devel/llvm sys-libs/libcxxrt

These are the packages that would be merged, in order:

I'm sorry but we can't provide proper support for multiple versions of LLVM packages.  If you can still reproduce the problem with 7.0.1 series, please open a new bug.
