It seems that the build system still invokes x86_64-pc-linux-gnu-g++ but with the clang mkspec, thus passing clang-specific flags that cause the error.

How are you specifying the compiler? The build.log says that CXX is unset.

Did you build dev-qt/qtcore with clang?

CXX is specified per package. I don't know if qtcore was built with clang or not.

I had the same problem with dev-qt/qtwebsockets:5.

Rebuilding dev-qt/qtcore with GCC and then trying qtwebsockets again solved this issue for me.
