You will then also need to add * '-lgstpbutils-0.10' manually to your LIBS line. * * ## Library initialisation * * Before using any of its functions, applications and plugins must call * gst_pb_utils_init() to initialise the library. * */ #ifdef HAVE_CONFIG_H # include "config.h" #endif #include "pbutils.h" #include "pbutils-private.h" #include "gst/gst-i18n-plugin.h" static gpointer _init_locale_text_domain (gpointer data) { #ifdef ENABLE_NLS GST_DEBUG ("binding text domain %s to locale dir %s", GETTEXT_PACKAGE, LOCALEDIR); bindtextdomain (GETTEXT_PACKAGE, LOCALEDIR); bind_textdomain_codeset (GETTEXT_PACKAGE, "UTF-8"); #endif return NULL; } void gst_pb_utils_init_locale_text_domain (void) { static GOnce locale_init_once = G_ONCE_INIT; g_once (&locale_init_once, _init_locale_text_domain, NULL); } /** * gst_pb_utils_init: * * Initialises the base utils support library.
