You need to install the libc++abi1 package.

When trying to build a project (e.g. QtCreator) with Clang 3.7 and libc++, I get the linker message

        /usr/bin/ld: cannot find -lc++abi

I found some code in gcc.js which explicitly request the library if targetOS is Linux

        if (product.moduleProperty("qbs", "targetOS").contains("linux") && stdlib === "libc++")

But libc++abi seems not to be available for Linux (at least not for Ubuntu 15.10). The documentation in http://libcxxabi.llvm.org/ leads to the assumption that it's only available on Apple systems. (And in fact, on my Mac there is such a library.)

Any hints?
