I got a situation, I can’t get a program compile since I splitted the files cause i thought it was too big.
Once the files is all merged in one, it works perfectly. Now that i splitted them, the compiler gives me the following error:

This is driving me crazy. I can’t get these to work when I split them.
And I find it a more organized thing, And I really wanna do it.

I’m dispose the files, so you guys can check out if you want.

Header main.h(the only header in the project. Although I had more than one for each .c file):

    It looks like the file include\allegro\alcompat.h is defining the same symbol (fnt_datafile, snd_datafile) multiple times, wherever you include it.

    If these are meant to be globals, they should be declared extern in the header and defined in a single implementation file.

    If they’re methods, they should be declared inline.

    It works when there’s just one file because that means just one translation unit exporting those symbols.
