hi all!!
I'm building a little project about representation of function,
and i need a parser to scan the strings i send to the main function.
using the bison program i get the followin message
bison -d Parser.y
bison.exe:bad address
i tried also to use the byacc program (for what i know is similar),
and the flex program, but this generate other problems, in fact
the compile fase was no problem, but at link time, the ld warn about
an unreferenced function "yywrap()" called by the .c files
generated by the byacc program. This function is declared as 'extern',
so i think it should be declared in some other file (generated by some
other programs)
maybe yywrap() is a function generated by bison (but bison don't want
to run)???
how to resolve the 'bad address' problem in bison??
P.S. in the makefile i compile using g++ -D__cplusplus ..list of files
sorry for my bad english
if you can't reply me on the mail list, please write at coea77 AT tin DOT it =
first or at coea AT libero DOT it or at mcodato AT dsi DOT unive DOT it
thank you
Mattia Codato
