That symbol is std::string::string(string&&), which will be found in the
libstdc++ from GCC 4.8, but not necessarily in earlier versions.  The error
message says it's looking in /usr/lib/libstdc++.6.dylib which is almost
certainly not from GCC 4.8, on Mac OS X it's probably from GCC 4.2

What is the output if you add -v to the linker options?

Have you tried using the compiler on the command line, instead of via Eclipse?
