请教下，为何我输入./run-all后不能打开startdemo
[root@localhost rgb_color]# ./run-all

Detected Qtopia edition 'pda' in /opt/FriendlyARM/mini2440/x86-qtopia/qtopia-2.2.0-FriendlyARM/qtopia

是不是我环境变量有误？
我把run-all改为：
#!/bin/sh
#export QPE_ROOT=/opt/FriendlyARM/mini2440/x86-qtopia/qtopia-2.2.0-FriendlyARM/qtopia
cd /opt/FriendlyARM/mini2440/x86-qtopia/hello/
../qtopia-2.2.0-FriendlyARM/qt2/bin/qvfb -width 240 -height 320 -depth 16 &
#export CAMERA_DEVICE=/dev/video1
#qtopia-2.2.0-FrinedlyARM/qt2/bin/qvfb -width 640 -height 480 -depth 16 &
cd ../qtopia-2.2.0-FriendlyARM/qtopia/image
mkdir root 2>/dev/null || true
export HOME=$PWD/root
cd opt/Qtopia
export PATH=$PWD/bin:$PATH
export LD_LIBRARY_PATH=$PWD/lib:$LD_LIBARAY_PATH
export QTDIR=$PWD
export QPEDIR=$PWD
export KDEDIR=$PWD/../kde
sleep 3
cd /opt/FriendlyARM/mini2440/x86-qtopia/qtopia-2.2.0-FriendlyARM/qtopia/bin
./startdemo
就可以了
