i get all these errors when i try to compile a very simple allegro program (keep in mind i just started allegro today)

liballeg_s.a? Isn't that the library you link against for static linking? The file should just be liballeg.a IIRC.
The docs are usually good enough for most of us; between that and the example code that comes with Allegro, you'll pick up the basics in no time. Along with that, there's the Allegro Game Development Network and Pixelate Magazine. But really, most of Allegro is pretty straight-forward, so just try using it and post a new thread if you run into any difficulty. [smile]

the problem is that when i try to do anything other than the basic hello world program i get tons of errors such as

and another thing is that how come all the examples are .c files can you only use allegro with c??
Allegro works with C++ just fine. Your errors seem to be related to syntax problems - post the code that isn't working.
