Wireshark-dev: Re: [Wireshark-dev] Wireshark no longer builds on SuSE 11.3

The code is simple enough (from glib-2.42.2 ).


* g_list_free_full:

* @list: a pointer to a #GList

* @free_func: the function to be called to free each element's data


* Convenience method, which frees all the memory used by a #GList,

* and calls @free_func on every element's data.


* Since: 2.28



g_list_free_full (GList          *list,

                  GDestroyNotify  free_func)


  g_list_foreach (list, (GFunc) free_func, NULL);

  g_list_free (list);



To provide the function for systems not having it, Evan didn’t like the function cast though even though it’s used by glib.


As for dropping SuSE 11.3 it’s perhaps time…

I was hoping to say, let's drop SuSE 11.3, as SuSE 11.4 has glib version 2.28, which includes the function. Also ReadHat 5 drops support by the end of next month. But SLES still supports it until 2019.


As for the convenience method, I would not provide a compatibility header, as this would require additional checks and defines. Just hardcode the functionality in this case, although it seems to be a burden. An utility function which masks the compatibility could also be a possible solution. In extcap I came across this issue quite some time, and most of the time I ended up hardcoding the functionality.

This function is very useful and open-coded many times, should we
provide a compatibility header for older GLib?
Kind regards,
