我在tiny6410上移植了Qt4.8.1，交叉编译了一个可执行程序放到开发板上，但是一运行就没有反映了，我setqt4env的内容如下:
#!/bin/sh
if [ -e /etc/friendlyarm-ts-input.conf ] ; then
. /etc/friendlyarm-ts-input.conf
fi
true ${TSLIB_TSDEVICE:=/dev/touchscreen}
TSLIB_CONFFILE=/etc/ts.conf
export TSLIB_TSDEVICE
export TSLIB_CONFFILE
export TSLIB_PLUGINDIR=/usr/lib/ts
export TSLIB_CALIBFILE=/etc/pointercal
export QWS_DISPLAY=:1
#export LD_LIBRARY_PATH=/usr/local/lib:$LD_LIBRARY_PATH
export LD_LIBRARY_PATH=/opt/Qt4.8.1/lib:$LD_LIBRARY_PATH
export PATH=/bin:/sbin:/usr/bin/:/usr/sbin:/usr/local/bin
if [ -c /dev/touchscreen ]; then
export QWS_MOUSE_PROTO="Tslib MouseMan:/dev/input/mice"
if [ ! -s /etc/pointercal ] ; then
rm /etc/pointercal
/usr/bin/ts_calibrate
fi
else
export QWS_MOUSE_PROTO="MouseMan:/dev/input/mice"
fi
export QWS_KEYBOARD=TTY:/dev/tty1
export HOME=/root
