Hi together,
I have made a reentrant (pure) flex parser without the c++ option. Now I am
trying to build the same parser with the c++
option to make an input with fstream (and use of iostream) possible.
So, there are some problems, it seems that the yylex() function doesn't take
any Parameter in the c++ option, but I need a version which takes a Parameter
like: int yylex(YYSTYPE *lvalp) or so, to give the tokens to the bison parser.
Any ideas?
Another possibility would be that somebody can tell me how to use fstream and
iostream objects without the c++
option declaration (but on a pure parser)
Kind regards
Markus
