I got the Allegro dev libraries, wrote and compiled a simple application, and ran it on my computer, and it worked fine. I had a friend test it, but it did not do anything when double clicked. I think the problem is that he does not have the Allegro library installed, so the program doesn't work. Is the only way to make it work for him to manually install the library and dependencies, or is there some way to package the necessary libraries with the application?
EDIT: Sorry, I meant to say I was using Allegro 5.
