I recently purchased Turbo C++ 3.1 for Windows from Borland (old, I know), and I am trying to teach myself OWL programming, but I keep coming up with these stupid errors, even on those programs that came with the compiler. It says:
Fatal ..\OWL\INCLUDE\OWL.H 40: Error directive: OWL applications must be built with either WIN30 or WIN31 defined.
How can I fix this stupid error which is keeping me from programming in Windows! Thanks!
