ximagesink not listed in config menu (disable-x)

[ericcardmanNo3]

Can you please tell me how to build ximagesink (gstreamer) in buildroot. How to make enable-x?
I can run make on \sys\ximage. But when loading libgstximagesink.so on the target i get unresolved symbol XFree. XFree is defined in libX11.so.

Please someone tell me how to solve that problem.

Thx.
