--- Comment #7 from Markus Trippelsdorf <trippels at gcc dot gnu.org> --- Thanks. I get with gcc-4.9: ... Linking CXX executable ../../../Binaries/test_runner CMakeFiles/test_runner.dir/test_runner.cpp.o:test_runner.cpp:function boost::filesystem::path::path<boost::filesystem::directory_entry>(boost::filesystem::directory_entry const&, boost::enable_if<boost::filesystem::path_traits::is_pathable<boost::decay<boost::filesystem::directory_entry>::type>, void>::type*): error: undefined reference to 'boost::filesystem::path_traits::dispatch(boost::filesystem::directory_entry const&, std::string&)' collect2: error: ld returned 1 exit status tests/common/TestRunner/CMakeFiles/test_runner.dir/build.make:113: recipe for target 'Binaries/test_runner' failed Note that I'm using the new C++ ABI already and I don't have a testbox that uses the old ABI. So someone that still uses the old ABI needs to debug this further...
