What compiler do you suggest then (because, at the moment, I'm using Dev-C++)? Thanks
Dev C++ isn't a compiler, it's an abandoned text editor that is usually distributed with an old out of date version of GCC. I suggest a more recent version of GCC.
Also, judging by all the posts about installing Allegro with Dev-C++ (there's even a sticky...), it doesn't seem to work well. But I don't even use an IDE and I have no problem installing things with apt. I just think people would have less issues in these areas without Dev-C++.
No one can agree how to count how many types of people there are. You could ask two people and get 10 different answers.
