Straight out of man gcc (RTFM!! ;>):
Linker Options
-llibrary -nostartfiles -nostdlib -static -shared
-symbolic -Xlinker option -Wl,option -u symbol
...snip..
-static
On systems that support dynamic linking, this pre-
vents linking with the shared libraries. On other
systems, this option has no effect.
You capitalized it wrong :-) also look at the ld option, -Bstatic as
opposed to -Bdynamic. It depends on whether you're passing the option
to cc or ld, it seems, as they have different syntax. So just add
-static to CFLAGS and you should be fine.
