Do I need static libraries to statically link?

Question

On \'C\', Linux,

Do I need static libraries to statically link, or the shared ones I have suffice? If not, why not? (Don\'t they contain the same data?)

Answer 1

All libraries you link into a statically linked program must be the static variant. While the dynamic (libfoo.so) and static (libfoo.a) libraries have the same functions in them, they are different format files and so you need the matching type for your program.
