Ric,

            Although I got to compile the library, I can get rid of some
compile errors. I tried some of the examples and the behavior is the
same. It says something about pure virtual functions not being defined
in parser.hpp:

virtual int LA(int i)=0;

virtual RefToken LT(int i)=0;

 

I had a look and they are not defined in parser.cpp, only in
LLkParserparser. Any ideas?

 

Here are the details (from building expr example):
