Re: Problem with Gtk::Window in dynamic library

["Volosatov Alexander" <rope-walker yandex ru>]

Try this:
main.cpp
-----------------------------
#include <locale.h>
#include <libintl.h>
#include <gtkmm.h>
#include <glibmm.h>
#include <iostream>
using namespace std;

int main(int argc, char ** argv)
{
    Glib::Module module("./open_dialog.dll");
    if (module)
    {
        cout << "\nmodule loaded ok";
        Gtk::Window* (*func)(void);
        string str("open_dialog");
        if (module.get_symbol( str, (void *&)func))
        {
            cout << "\nfunction found";
            Gtk::Window *wnd;
            wnd = (*func)();            
            cout << "\nafter function";
            cin.get();            
            Gtk::Main::run(*wnd);
        }
    }    
    cin.get();    
    return 0;
}

-------------------------------
library
-------------------------------
#include <iostream>
#include <gtkmm.h>
using namespace std;

extern "C" Gtk::Window *open_dialog()
{
    Gtk::Window *dialog = new Gtk::Window();
    return dialog;
}
