From: Zhao Liu <zhao1....@intel.com> As commit 3e015d815b3f ("use g_path_get_basename instead of basename") said, g_path_get_dirname() should be preferred over dirname() since the former is a portable utility function that has the advantage of not modifing the string argument.
Replace dirname() with g_path_get_dirname().
