Look at ar.
ar sru libmine.a this.o that.o theother.o
will do.
Do:
ranlib libmine.a
if it's linking slowly.

On the link step, put -Ldirectory so ld can find it, like -L. if it's in
the local dir, and do -lmine (assumes it's called libmine.a)

You could just put libmine.a on the link line, but then the whole thing
will be linked in no matter what. Using the -l flag ensures that
only the .o files referenced are linked in.
Put the -l entry last, after the .o files.
