How to enable touchscreen in Xfbdev

[Prashant J Zaveri]

Hello,

I have cross-compiled Xfbdev for ARM9 core and want to run it on a
board powered by Freescale's i.MX21 processor and running Kernel
Vanilla 2.6.22 with a few board-specific patches.

I m using following flag to cross compile X server :

--host=arm-linux --enable-kdrive --disable-kdrive-vesa
--disable-xephyr --disable-xorg --disable-xorgcfg --disable-dri
--disable-glx --disable-ipv6 --disable-xglserver --disable-xglxserver
--disable-xsdlserver --disable-xwinserver --disable-xnest
--disable-xephyr --disable-dmx --enable-tslib --disable-xinput
--enable-touchscreen

It enables tslib, but TOUCHSCREEN is still showing undefined in header
files. How to enable touchscreen support in server ?
