While i followed the steps involved in installing arm_qtopia.tar.gz provided with friendly arm device. I did the following things

#tar xvzf arm_qtopia.tar.gz -C/

It created a directory called arm-qtopia in the file system....

Then i clicked 'build-all' shell script to build all the elements in the folder arm-qtopia.....

While it did all the things while building qtopia...at some point it gave an error as following....

/bin/sh:arm-linux-g++:command not found
make[1]: ***[allmoc.cpp] Error 127
make[1]: Leaving directory '/arm-qtopia/qtopia-2.2.0-FriendlyARM/qt2/src'

...

Thus my application which i want to port on ARM device is not getting compiled using qmake of arm-qtopia....
What is the problem?? Please guide.....
