I'm not an expert on archives but I think your problem might be that it is a 
library but you pass it in such a way the compiler thinks it's an object 
file.

Try "ar -crus libfileout.a file1 file2 file3; gcc file.c -lfileout.a". 
Perhaps you need to add "-L." to the gcc command for it to find your library 
(which I'm guessing is in the current directory).


Right,
