./test2 -qws &You need to put ./ in front of your command - by default Linux does not look for binaries in current directory for security reasons.

@MhM93 Well, it tells you what is wrong: one of the shared libraries your application needs has a wrong version.
Doldd test2to see which libraries are needed. You probably need to deploy your app properly to your target, means: copy needed libraries as well. For more information see: http://doc.qt.io/qt-5/linux-deployment.html

could any one help me?
I am confused -
@MhM93 "It said 32 bit compiler, when I download the gcc I extract gccx64" - the compiler itself is a x86_64 (64bit) binary - this does not mean that it generates 64bit binaries. You are building for ARM 32bit, so it generates ARM 32bit binaries.
You should do this (as I suggested before) on your target device:
ldd ./test2It will should you which libraries are used by your executable.
"./test2: error while loading shared libraries: ./test2: unsupported version 9813 of Verneed record" - says that one of the libraries on your target has the wrong version number.

@MhM93 said in problem in running Qt app on nanoPC-T2:
Verneed record
Something is wrong with your executable. Can you show the whole build log (compiler output)?
