I've been very confused with trying to 'install' allegro. I found out that devc++ has a package manager tool that would do it for me. I'm not very good at all this sort of installation stuff so I thought that would be helpful. So i found a 'devpak' online here: http://devpaks.org/details.php?devpak=1 . I installed the pak, and I started a new, empty, project and tried to run this code:

#include <allegro.h>

int main(void)
{
        allegro_init();
        allegro_message("Hello World!");

        return 0;
}
END_OF_MAIN()

I get these errors in my compile log:
Compiler: Default compiler

Was there something else I was supposed to do after the devpak was installed?

How do I add that if I am using a devpak via the package manager?

I had this exact same problem. The way I fixed it is by copying alleg42.dll from the bin folder into the C:\WINDOWS\system32 folder.

I don't see the liballeg.a file anywhere in my file tree. I know that it exists within the devpak though\, I just can't seem to get to it.

I was under the impression that it would work properly after installing the devpak.

what additional steps are needed?

My question is, how do I do that with a DEVPAK installation of allegro?

EDIT: Problem solved, the trouble was that I had more than one installation of Mingw... I didn't realize devc++ installed it as well.
