为什么每次运行必须重新导入路径? [复制链接]

版本:qtopia-free-1.7.0
qtopia安装路径:/root/Qt_x86/qtopia-free-1.7.0
运行:
______________________________
export QPEDIR=/root/Qt_x86/qtopia-free-1.7.0
export QTDIR=/root/Qt_x86/qtopia-free-1.7.0
export PATH=$QTDIR/bin:$PATH
export LD_LIBRARY_PATH=$QTDIR/lib:$LD_LIBRARY_PATH
export QTDIR=$QTEDIR
qpe
就提示:
_______________________________

[root@host-f-48 root]# qpe
Connected to VFB server: 240 x 320 x 32
Cannot find font definition file /lib/fonts/fontdir - is $QTDIR set correctly?
_________________________________

echo $QTEDIR,
echo $QTDIR 均无显示,请问大家,在安装过程中不是已经设置的过么?为什么没有保存?

必须重新再次设置路径,才能运行qpe!

请问这是什么问题?如何解决?谢谢!
