then I install qt4.8.6 with this command:

./configure -embedded armv7l -prefix /opt/Qt4.8 -xplatform qws/linux-arm-g++ -no-webkit

and make and make install are successfully. when I open qt creator and set the qt version with this qmake(/opt/Qt4.8/bin/qmake) but show this error" No compiler can produce code for this Qt version. Please one or more compiler"

could you help me.
thanx in advance

I found the answer: I should create my GCC and set it to my Qt version

The problem wasn't the missing Qt version but the missing tool chain.

In Tools → Options → Tool Chains add GCC and set your gcc path as the Compiler path.
