I found interesting comments regarding this in <URL: http://allanmcrae.com/2015/06/the-case-of-gcc-5-1-and-the-two-c-abis/ > and <URL: https://llvm.org/bugs/show_bug.cgi?id=23529 >.
Apparently clang do not understand a new gcc invention, the API tag, which is inserted in symbols build using -std=c++11. According to <URL: https://www.reddit.com/r/cpp/comments/442b38/clang_38_gcc_53_incompatibilities/ >, We might get it working by building the library using --with-defualt-libstdcxx-abi=gcc4-compatible to avoid the problem, or perhaps we need -D_GLIBCXX_USE_CXX11_ABI=0. More testing is needed. -- Happy hacking Petter Reinholdsen
