As far I know (not much) flex2.4 has a simple and efficient support
for C++ that consists of writing a C++ class header, while flex2.4 (and
up) just write a method. You should be able to use any i/o flavor
including iostreams...


flex++2.3.*-* (that I've written 2 years ago with bison++1.21-*) is
much more complex and uses preprocessor like feature... it works, it
is much customizable but it it too much complex... I really should
have used a scheme like flex2.4 for fle++ and bison++ (regrets!)

there was one at ftp.th-darmstadt.de, but I've received query that
make me think it is no more there. it were also on a FTP server
around cse.unl.edu, but I've no more info. try at our Web server (we
don't have a ftp server on our gatekeeper) http://www.icdc.fr/ and
follow the links ... (/ftp is mapped to the old ftp directory)

I agree. Much more info should also be proposed. anyway read the
news:comp.compilers FAQ and relatives.


I think flex++2.3.*-* and bison++1.*-* are not the best choice since
they are not standard and are no more really supported by me since
I've much work here (icdc.fr).


look for bison-A1 for a bison C++ support
see also for PCCTS (news:comp.compilers.pccts).
look for flex2.4 nd up for a flex C++ support
look for commercial products liek YACC++
tell us about some


flex2.4 and up is in my opinion a very good solution. anyway like
many peoples I'm demanding for a good c++ support for bison.
