As I recall, bison itself doesn't have C++ support, but it might have
changed since I used it. Anyway, the "support" is mainly about iostream
library. As long as you don't need it, you can use bison+flex+c++ just
as you would use them with C. If you really need it, then there is a
bison fork with iostream support built in (plus it generates a class
instead of a "flat" file). It is called bison++ and it works with
flex++. And it has an example.


Hope this helps,
