Looks like the fix for bug #786627 has nasty side effects with clang. From the ebuild: # bug #786627 append-cppflags -std=c++14 From config.log configure:4574: checking whether the C compiler works configure:4596: x86_64-pc-linux-gnu-clang -O2 -pipe -march=x86-64 -frecord-gcc-switches -fno-diagnostics-color -fmessage-length=0 -fno-strength-reduce -std=c++14 -Wl,-O1 -Wl,--as-needed -Wl,--defsym=__gentoo_check_ldflags__=0 -fuse-ld=lld conftest.c >&5 clang-13: warning: optimization flag '-fno-strength-reduce' is not supported [-Wignored-optimization-argument] error: invalid argument '-std=c++14' not allowed with 'C' I was thinking where does that come from? Well the ebuild itself.
Would recommend replacing the `append-cppflags -std=c++14` by something along the lines export CXX=tc-getCXX -std=c++14 to enforce the use of c++14 compiler without adding options to the C compiler. Setting language standards in compilers could be an interesting addition for the toolchain-funcs eclass.
