Normally the procedure for debugging a shared library is much the same as for debugging an executable - the main difference is that you may be unable to set a breakpoint until the shared library is loaded into memory. You attach the debugger to the main executable.

If you are debugging an application that is not owned by you, but is using your module in a plugin architecture, you still use the same method. Make sure (as always) that you have debugging information available for your shared library. In windows, you would generate a .pdb file. With gcc, I think you specify a special compiler flag (-g?) to ensure that debugging information is supplied. You attach the debugger to the third party application.
