I suggest you just take the weekend and write your own
parser and lexical analysis, void of Flex and Bison.
I did and I have never looked back.
:-)
If you advice to reinvent the wheel, it's bad advice. But it makes sense
to know alternatives which may be easier to use or more convenient to work
with. For example, I very much like re2c lexer, it is simple, fast, and
can be used in ad-hoc manner inside regular c++ sources.
I grew up with Lex and Yacc.
Issues (none of which were ultimately show stoppers).
- Multiple sets in the same program.
- Error reporting.
- Memory recovery on errors.
- Size constraints.
- Parsing poorly designed languages.
- Parsing the idiosyncrasies of well designed languages.
- Porting to other platforms.
- GPL.
Now I just brute force it with C++
minimizing my dependencies on others.
Not wanting to start an off topic thread.

Windows does not come with built-in flex / bison support, nor
does mingw, nor (to the best of my knowledge) does Qt. (This
is true of a lot of unix-world libraries that are nearly universal
on various flavors of unix.)
I would expect (but don't know for a fact) that you could find a
third-party port of flex / bison to windows that you could then
use for your Qt / flex / bison project. In general, you would be
best off if you found a port built with the same compiler as your
Qt project (apparently mingw). One way to insure this would be
to build it yourself. If you're careful and know what your doing
you can sometimes get away with using c libraries compiled with
a different compiler (For example, the ms system calls were not
compile with mingw and you can call into those.), but it's likely to
be more bother trying to mix compilers than compiling something
like flex / bison yourself.

Happy Parsing!
