It's better if I start a new thread.
I try to repost....
Can anyone give me some hints on how to complete
compilation phase under linux?
I have linux debian 2.2 (potato). Bison and flex report
to me a lot of problems with "implicit declaration of
function int yylex()" and so on. I'm not skilled with yacc and lex.
This first error I succeed to fix removing comment for yylex() in alternate linkage
specification somewhere (I do not remember, probably c++.reverse.*).
But errors continue...
Is there a universal solution?!
P.S. Tell me if I'm noisy, please. If so, I stop frustrating you.

TIA
