I use this guide document to install cross compiler 4.9.3 and also qt4.8.6. http://wiki.friendlyarm.com/wiki/index.php/Ubuntu_Core_with_Qt-Embedded#Develop_Qt_Application

@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

@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)?

this is my file:

I first wrote it in qt, then compile it@MhM93 I'm not going to build this (I would need to install the same build tools first), so please post the build log...
