Includes some headers fixed the problems. Open the CharScanner.cpp and put this at the header.

#include   >fstream<
#include   >strings.h< // before
#include   >antlr/config.hpp<
// and

#include >antlr/exersharedinputstate.hpp< // after
#ifndef EOF
    #define EOF     std::ifstream::traits_type::eof()
#endif

Run `make clean` and the `make; make install`. Compile success, Yeah!
