If you want to link, say, libapplejuice statically, but not, say, liborangejuice, you can link like this:

gcc object1.o object2.o -Wl,-Bstatic -lapplejuice -Wl,-Bdynamic -lorangejuice -o binary

There's a caveat -- if liborangejuice uses libapplejuice, then libapplejuice will be dynamically linked too.

You'll have to link liborangejuice statically alongside with libapplejuice to get libapplejuice static.

And don't forget to keep -Wl,-Bdynamic else you'll end up linking everything static, including libc (which isn't a good thing to do).
