Using flex++ and bison (not ++) with c++

[daniele.calisi]

Hi everyone,
after some days spent in long searches with google, I still not have
found a solution with this problem:

I need to use flex (or flex++) and bison (but not bison++) in order to
create a simple expression parser (that reads from a string, but this
is another problem)

I have problems with the fact that I cannot use bison++, and bison
creates a c file... do you have any simple tutorial on how create such
a thing?

Why not using boost::spirit?

Recent versions of bison can be used with C++. You can see a sample in my
open source z80 assembler:

http://www.arrakis.es/~ninsesabe/pasmo/

The last version, still under development, has a bison parser that compiles
in C++, inside a namespace and using a class as lexer.

Take care, bison manual warns that c++ related features can be changed in
next releases.

Man, that thing is incredible. I wrote an incredibly validator for a
file format we made up in less than 2 hours, with the learning and
everything.

Where can I get more info? I want to look into the possibilty of
feeding parse() a stream instead of character sequence. Flipping
through the docs has been helpful up to this point but I need more;
maybe it's in there but I can't find it...where is a good full coverage
tutorial on spirit (not just regurgitating the calculator example in
the docs for instance)?

Nevermind...perfectly obvious if you just keep reading a bit.
