Hi,
I have used FLEX/BISON for scanners and parsers many times before, but now I
should
parse 3 different files (with different grammars) in one program.
Both BISON and FLEX allow to change their global variables using the -p (or
-P) commandline
option. Multiple use should therefore be possible.
But...
When using e.g. -paa I get an unresloved symbol "aaerror" (was yyerror
before) while linking.
yyerror seems to be in libbison.a
Anyway, there might be more problems, I haven't figured out yet.
Has someone successfully applied multiple scanners/parsers in one program
using FLEX/BISON ?
I studied the docs, but didn't find any hint.
Any ideas welcome !
Tony
