The error means that location_type has not been declared as a type before the following declaration: void parser::error(const location_type& a_loc,const std::string& a_msg) It most likely means that the parser.y file is missing a #include directive with a header that defines the type. Probably because of a mistake in the input file from which parser.y was generated. It's not really a problem specific to GCC. I suggest searching the Web for the error message. Martin
