[gst-devel] GStreamer beginer problem

[Chen Hailiang]

thinks Tim, I got the lastest version now,and found some unuseable methods 
has made up, such like gst_element_unref() was not used again. But I still 
can't use 'gst_element_factory_get_klass()', 
(error:elementInfo.c:(.text+0x60): undefined reference to 
`gst_element_factory_get_kalss').
my source codes were copied from <5.4.1. Getting information about an element 
using a factory>,the newest version of the application development 
manaul(0.10.20.1).may any other reason to bring about that?
think you.
