g_module...: module calls function of core applicatioin

["Tobias Kipfelsberger" <tobias kipfelsberger gmx de>]

Hi...
I have a plugin which is registered and loaded with the g_module functions.
So far so good everything works find.
But how can i let the modul access a function of the coreapplication?

Example:
in CoreApplication.h:

G_MODULE_EXPORT void 
setCoreMenuAppbarText (const gchar* text)
{}

in plugin.c:

#include "CoreApplication.h"
void
xyz ()
{
     setCoreMenuAppbarText("test");
}

as i execute the programm... i always get a undefined symbol error.

Thanks in advance...
Tobi
