Catching Exception in Static Library

Hello-

I'm linking a static library (freeimage.a) against my OS X application
(Xcode). The static library throws an exception (throw [number]) I want
to catch in my application. How can I propagate this C++ Exception into
my program? Is there any compiler switch?

I tried to compile the static library with -shared-libgcc, but this did
not help.

I also checked if exception are catched using the example below and the
handler works. However, not on the library exception.

Any ideas are welcome!

Thanks!

int number=41;
try {
// here I call my library ...

// just for exception testing
throw number;

} catch (...) {
printf("exception");
}
