Mike, Thanks so much! This solves the problem. This option was not there when I do "configure --help". Now I have lots of undefined references like these, I think most likely libglib is not up to date: ../../../gst/.libs/libgstreamer-0.10.so: undefined reference to `g_param_spec_object' ../../../gst/.libs/libgstreamer-0.10.so: undefined reference to `g_utf8_validate' ../../../gst/.libs/libgstreamer-0.10.so: undefined reference to `g_date_get_month' ../../../gst/.libs/libgstreamer-0.10.so: undefined reference to `g_value_get_float' ../../../gst/.libs/libgstreamer-0.10.so: undefined reference to `g_memdup' ../../../gst/.libs/libgstreamer-0.10.so: undefined reference to `g_type_interface_peek' ../../../gst/.libs/libgstreamer-0.10.so: undefined reference to `g_value_set_int64' ../../../gst/.libs/libgstreamer-0.10.so: undefined reference to `g_thread_pool_new' ../../../gst/.libs/libgstreamer-0.10.so: undefined reference to `g_flags_get_first_value' ../../../gst/.libs/libgstreamer-0.10.so: undefined reference to `g_slist_remove' ../../../gst/.libs/libgstreamer-0.10.so: undefined reference to `g_mkdir_with_parents' ../../../gst/.libs/libgstreamer-0.10.so: undefined reference to `glib_major_version' ../../../gst/.libs/libgstreamer-0.10.so: undefined reference to `g_value_unset' ../../../gst/.libs/libgstreamer-0.10.so: undefined reference to `g_source_set_priority' ../../../gst/.libs/libgstreamer-0.10.so: undefined reference to `g_strdupv' Feng
