Broken c++ std libraries on macOS High Sierra 10.13

Question

I recently bought a new MacBook on which I transferred my old session. Since then, and after i upgraded to 10.13, i can\'t get clang to compile anything including only iostr

Answer 1

I had exactly the same problem after transferring to macOS High Sierra (though, errors were not the same, but similar).

I found a workaround by renaming /usr/local/include to /usr/local/include_old (well, name does not really matter, just the fact that g++/clang will not search for headers in this folder anymore).
