    Make types struct to be compatible.

    How to make this warning clean

    typedef struct Recording_Settings recording_settings;
    struct Recording_Settings
        gchar *profile;
        gchar *destination;
    recording_settings rec_settings;
    typedef struct _GstEncodingProfile GstEncodingProfile;
    GstEncodingProfile *rb_gst_get_encoding_profile (const char *media_type);
    Warning: assignment from incompatible pointer type:

    static void profile_combo_change_cb(GtkComboBox *combo, gpointer userdata)
        GtkTreeIter iter;
        GtkTreeModel *model;
        /* Grab the encoding profile choosen */
        model = gtk_combo_box_get_model (GTK_COMBO_BOX (combo));
        if (gtk_combo_box_get_active_iter(GTK_COMBO_BOX(combo), &iter)) {
            gchar *media_type;
            gtk_tree_model_get(GTK_TREE_MODEL(model), &iter, 0, &media_type, -1);
            rec_settings.profile = rb_gst_get_encoding_profile(media_type); // Warning: assignment from incompatible pointer type
            g_free (media_type);

    Does rb_gst_get_encoding_profile does not return a gchar* as rec_settings.profile expects.

    The input for the function is defined as a gchar*, but the prototype expects const char *

    Don't try and suppress the warnings, try to fix them.
