I had been referring to https://community.freescale.com/message/324447#324447 where on our target board it is gnome distribution in which xcb binaries are outdated. So we configured with -no-xcb and atttached is the configure line output.

Please suggest in this regard.

Thanks and Regards,
Ramakanth

Run ldd -d -r on the plugin. Does it complain of any libraries not getting found? Or does it complain or missing symbols?

If it complains about missing libraries, set LD_LIBRARY_PATH to where those libraries are located.
