I have inherited some lex code that compiles cleanly on Solaris
(and AIX I believe), but refuses to compile on RedHat Linux...
Lex does not complain when it parses the source file, but gcc
will not compile the resulting C code.
Is there some additional switch that gcc needs when compiling the
code generated by flex ?
I am not a lex guru...so any thoughts on this would be greatly
appreciated.
This is what I get:
