Qtcreator Raspberry Pi Device Cross Compile Issue



  • Running from Ubuntu 16.04 host, compiling for Raspberry Pi, Device tests good, None QApplications run and debug fine. QApplications find this message when debugging or running remotely: qtcreator rasspberry QXcbConnection: Could not connect to display ... Worked for years, not it does not, seem the last sets of upgrades of Qtcreator may have broken this but I am not sure..

    ssh -X application works fine.. Problem is only from qtcreator ..

    ran qtcreator from bash shell with alias of ssh to ssh -X then ran qtcreator and tried to run application remotely still no good, qtcreator rasspberry QXcbConnection: Could not connect to display..

    Welded DISPLAY :0 in the run env symptom changes, QXcbConnection: Could not connect to display DOES NOT APPEAR in application display, however neither does the display of the application..

    I am lost.. any help here would be appreciated.. Worked for a year, not it does not.. no clue.. Madness is right around the corner.
