I was trying to compile official Hello World example of gnome applet
and end up having errors.
Here is the source code:
-----------------------
#include <gtk/gtk.h>
#include <panel-applet.h>
static gboolean hello_world_applet_start (PanelApplet *applet) {
GtkWidget *label;
label = gtk_label_new ("Hello World");
gtk_container_add (GTK_CONTAINER (applet), label);
gtk_widget_show_all (GTK_WIDGET (applet));
return TRUE;
}
static gboolean hello_world_factory_callback (PanelApplet *applet,
const gchar *iid, gpointer data) {
gboolean retval = FALSE;
if (g_strcmp0 (iid, "HelloWorldApplet") == 0)
retval = hello_world_applet_start (applet);
return retval;
}
PANEL_APPLET_OUT_PROCESS_FACTORY ("HelloWorldFactory",
PANEL_TYPE_APPLET, hello_world_factory_callback, NULL)
Compile command: (copied off of some guys post)
---------------------------
g++ -Wall -DGTK_DISABLE_SINGLE_INCLUDES -DGDK_DISABLE_DEPRECATED
-DGTK_DISABLE_DEPRECATED -DGSEAL_ENABLE `pkg-config --cflags --libs
gtk+-3.0 libpanelapplet-4.0` *.cpp -o helloworld
Error message:
--------------------------
