This is more of a gcc/gnu toolchain question, but it's related to
java and in the past y'all've had some good answers, so here goes:
I'd like to strip a jnilib so that non-visible functions are harder
to spot and futz with by hackers. Here's what I do: I use -
fvisibility=hidden and just make a few functions visible (those that
are needed for the JNI interface). After the library is compiled, I
use strip -x to strip, but no luck -- many of the functions I'd like
to hide are still visible when I type nm (they're just not global).
I've also tried strip -s, but this seems to break my library, so if
someone had a good example of how to use that, I'd appreciate it.
Another option to try is to pass "-exported_symbols_list <filename>"
to ld. That ensures that only teh symbols you specify are exported by
your binary. See the ld manpage for more details.
