g++: error trying to exec \'cc1plus\': execvp: No such file or          


        

Answer 1

You may have this issue as well if you have environment variable GCC_ROOT pointing to a wrong location. Probably simplest fix could be (on *nix like system):

unset GCC_ROOT

in more complicated cases you may need to repoint it to proper location
