gst-inspect-1.0: undefined symbol: gst_tracer_factory_get_type

[palash]

Gstreamer custom plugin can not be loaded, reporting no element. gst-inspect-1.0 shows error for the following command:

$ gst-inspect-1.0 /usr/local/lib/gstreamer-1.0/libgstmyplugin.so

gst-inspect-1.0: symbol lookup error: gst-inspect-1.0: undefined symbol: gst_tracer_factory_get_type

The most likely reason for this is that you compiled against a newer
version of the GStreamer includes and GStreamer library (maybe compiled
from source and installed into /usr/local/?), and that at runtime the
system picks up an older version of GStreamer, e.g. a GStreamer
installed from packages into /usr/lib.

Maybe you didn't run 'sudo ldconfig' after doing 'make install'.

Maybe you need to add /usr/local/lib/... to the LD_LIBRARY_PATH
environment variable or /etc/ld.so.conf*

You can check which GStreamer it picks up via:

 $ ldd /usr/local/lib/gstreamer-1.0/libgstmyplugin.so | grep
libgstreamer

Above command is showing following:

libgstreamer-1.0.so.0 => /usr/lib/arm-linux-gnueabihf/libgstreamer-1.0.so.0

First I installed gstreamer-0.10 then installed gstreamer-1.0 but I have uninstalled the gstreamer-0.10.

Thanks Tim, the library path was the problem. I tried with a fresh setup and it worked fine.
