Вот пример:
gcc -framework CoreServices -o test test.c
Из man-страницы Apple gcc (i686-apple-darwin10-gcc-4.2.1):
In addition to the options listed below, Apple GCC also accepts and
passes nearly all of the options defined by the linker ld and by the
library tool libtool. Common options include -framework, -dynamic,
-bundle, -flat_namespace, and so forth. See the ld and libtool man
pages for further details.
И с страницы ld man:
-framework name[,suffix]
This option tells the linker to search for `name.frame-
work/name' the framework search path. If the optional suffix
is specified the framework is first searched for the name
with the suffix and then without (e.g. look for `name.frame-
work/name_suffix' first, if not there try `name.frame-
work/name').
