I am currently using flex/bison to generate a lexer & parser, with the whole project in Xcode. However the files generated by flex & bison produce a couple of compiler warnings when they are compiled. How can I suppress these warnings?
I know I can suppress warnings on a per-file basis through the 'Build Phases' tab, but the generated files don't appear here.
I tried adding the flag [-w] to the source file [ie, the .lpp and .ypp files], however this didn't work - Xcode understandably tried to pass that flag to bison, which it didn't like.
