Gdb is unable to locate the definition of std::string when compiled with

Answer 1

clang trusts that debugging symbols for libstd++ are available, so you have to install them. See ks1322's answer for how to do that on Fedora. On Ubuntu, run:

sudo apt-get install libstdc++6-dbgsym

After that, things will just work.

Do not define _GLIBCXX_DEBUG since that'll break libstdc++'s abi.

-fno-limit-debug-info will make clang emit debug info that's larger than necessary, so I'd advise against that too. Just install the debug info package for libstdc++.
