The error message is "function aquire_screen() undefine". "Function makecol () undefine". I am using allegro5.0.10 for msvc10. I am also trying to run an edited version of on of the example game programe provided in the allegro package.
Can you give the exact error message rather than paraphrasing?
A quick search of the allegro-5.0.10 manual doesn't document any acquire_screen function, although it is documented in version 4 of allegro. Perhaps you're copying code meant for a previous version?
