[build] targeting different versions of libstdc++
If I make a system with libstdc++6-dev, libstdc++7-dev, and libstdc++8-dev on it, is there a way to tell clang to use one over the other? By default it will use the latest one. I know that for linking one can use the clang flag "--gcc-toolchain=/usr/lib/gcc/x86_64-linux-gnu/7" to get the link to point at it, but I'm not sure if this also handles the header paths or not. If this option works for both header inclusion and for linking, would I need to specify it as <cxxflags> and also as <linkflags>? Thanks, Jim

No idea. Intuitively, I would expect it to work, though.
