C++ performs symbol mangling, which is why libglade could not find the
symbol. If you look at the object file containing the function with nm,
you should see that the function name there is different.
To fix the problem, you will have to declare that your function should be
usable from C. Something like:
extern "C" void on_zoom_valeur_activate (GtkWidget * w, gpointer data);
This only limits what you can put in the argument list to C syntax (ie.
no default arguments or alternate implementations with different
argument lists) -- it doesn't limit you to only C syntax inside the
function body. This will prevent the compiler from mangling the symbol
name.
