Xorg-1.7.3 XCALIBRATE touchscreen

[Marco Cavallini]

Hi,
I am using an ARM based architecture and I am trying to enable
touchscreen calibration without success.
I built Xorg version Xorg-1.7.3 configured with --enable-xcalibrate
but I didn't get this extension in my Xorg, so when I try to call xtscal
I get this error:
 # xtscal
 XCALIBRATE extension missing: Success

I debugged a bit the following packages (xtscal_0.6.3,
libxcalibrate_git, libxext_1.1.1) and I realized that the problem is
into Xorg so I wonder how could I enable XCALIBRATE.

Any help would be greatly appreciated.
If any functionality is missing I'd like to get a hint about how to
proceed to implement, debug and test it.

Thank you
