I am working on QT Creator 3.4.2 (opensource) Based on Qt 5.5.0 running on ubuntu 14.04LTS. We are trying to create our own application and run it on a SABRE SD platform before creating our own customized board.
We are able to cross-compile correctly, copy the built file to the SABRE SD platform .... but when we try to execute it, we get the following error.
QXcbConnection: Could not connect to display
We run Yocto Linux 3.14.28 on the development platform.
Could you please give us some hints on how to solve this issue?
Thank you very much for your help.
