ts_config() problem

TanLe
I have cross compiled Qt4.7.2 and tslib successfully.
I have trafered the compiled tslib and Qt to Mini210s
But when run example program.

It is give following error.
                                                   
    
QWSTslibMouseHandlerPrivate: ts_config() failed with error: 'No such file
or di'
Please check your tslib installation!  

I found this subject in forum, however everyone doesn't solve this problem
Some one help me come out of this issue.

Check the environment variables the libts uses to "know" which device node
if should use.

Check your /etc/profile, it should contain something like this:

export TSLIB_TSEVENTTYPE=INPUT
export TSLIB_CONSOLEDEVICE=none
export TSLIB_FBDEVICE=/dev/fb0
export TSLIB_TSDEVICE=/dev/input/event1
export TSLIB_CALIBFILE=/etc/pointercal
export TSLIB_CONFFILE=etc/ts.conf
export TSLIB_PLUGINDIR=/usr/lib/ts

if it doesn't, try manually declaring them (just enter into the console)
and see if that helps. The device might be event0 ts and the plugindir
might be in usr/local/lib, check these.
