[antlr-interest] Problems with using the C++ grammar provided at antlr.org.

[Gordon Prieur]

Min,

    Unless you left out compiler options (below), the line you typed
would generate lots of messages. You need at least several options.
Try "g++ -c -I<path-to-antlr-cpp-header-files> -g CPPLexer.cpp".
You'll have to supply the path, but you need to tell the compiler
where the antlr cpp module's include files are. You might still
get lots of errors, but there should be fewer and more related
to mistakes in CPPLexer.cpp.
