Broken Application after Qt 5.1 -> 5.2 update



  • I am building Qt through buildroot for an embedded system. I was running Qt 5.1 in buildroot 2013.11 and recently updated to 2014.02. After a full rebuild of the file system I reissued qmake on my application which compiled with no errors. I updated the file system on the embedded device (imx6) and copied my application to the device. When I run it the application runs like normal but the touchscreen does not work anymore and there is no text anywhere in the application. All the buttons are blank and when I add items to lists they do not appear. All of this is code that was working perfectly when compiled against Qt 5.1. It is a C++ application that is using a Makefile generated by qmake to build and link against Qt. All of the ui files were created in designer.

    Does anyone have any idea what might be wrong? I am going to revert back to 5.1 but eventually I would like to get it up and running with 5.2.

    Hi and welcome to devnet,

    Did you do a clean rebuild of your application ?



  • Yes I did. I performed a "make clean" and a full rebuild.

    i can interact with the buttons in my view by performing tasks such as hide and show but if I call setText on the button no text appears.

    Can you test it with the latest 5.3 ?

    In between, you should check the "bug report system":http://bugreports.qt-project.org to see if there's something about this
