How to catch exception thrown from library in GCC C++?

Question

When i use dlopen to dynamically load a library it seems i can not catch exceptions thrown by that library. As i understand it it\'s because dlopen is a C function.

Answer 1

You need to specify RTLD_GLOBAL flag to dlopen. This will allow correct weak symbol binding, so each typeinfo symbol for exception object will point at the same place, which is needed by exception processing ABI code.

Answer 2

This depends on the version of GCC you are using.
First of all, make sure you compile everything with "-fPIC" and link with the "-rdynamic" flag.
RTLD_NOW flag is still needed.
