What configure parameters are used for building gst-omx, can you attach
the config.log? What's the output of ldd on libgstomx.so?

Does your vcos library export the symbol vcos_global_lock at all? From
your logs it is loaded but this symbol is not found. This does not look
like a problem in gst-omx at all to me as gst-omx does not use this
symbol directly.

I would check if everything is ok with your toolchain, libc and dynamic
linker, and also check if the userland part of the RPi firmware is a
known to be working version.

The RPi firmware userland part is supposed to be in /opt/vc btw :)
