buildarm.sh

source /home/nicholas/qtopia-free-2.2.0-arm/setQpeEnv

qmake -spec qws/linux-arm-g++ -o Makefile.target *.pro

make -f Makefile.target clean

make -f Makefile.target

Use buildpc.sh if you want run it in computer.

source /home/nicholas/qtopia-free-2.2.0-pc/setQpeEnv

qmake -o Makefile.host -spec qws/linux-generic-g++ *.pro

make -f Makefile.host clean

make -f Makefile.host

After build it,put bin file to root file system.
For example /opt/Qtopia/bin/hello
The follow shell can get from /bin/run** (If you make it while run qtopia.)
