What are .a files?

Hi.

So what are they exactly? If I remember correctly, then SDL uses .a file too. At linking time I just had to -lSDL and a file called libSDL.a was linked. I also had to include a header called SDL/SDL.h or something like that.

if libSDL.a contains definitions of functions, then why can't the definitions be in a .o file? Thus, at linking time, I'd just link the .o file and be done with it.

.a files are static libraries, basically just collections of .o files.

how can I make my own collections of .o files?

use ar

Code:

---

man ar

---

should give you all the information you need.
