This page may be of help:
It describes recursive descent parsing using the camlp4 stream parser
extension and lex/yacc.
You may also be interested in this LLVM-based example in OCaml that uses
camlp4 for parsing directly:

I found flex and bison really tedious to use from C++. That was a long time
ago and there are probably better alternatives now though. Still much worse
than anything with first-class lexical closures and algebraic datatypes, of
