Is the message "QLock::lock(): Identifier removed" anything I should be concerned about?



  • I have a platform with an optional secondary display. Since I want to separate the two displays I've split the code into two applications, one for the primary display and one for the secondary. I start them by running
    @
    ./app_1 -qws -display linuxfb:/dev/fb0 &
    if [ -e /dev/fb1 ]
    then
    ./app_2 -qws -display linuxfb:/dev/fb1 &
    fi
    @

    But now I started to see the output:
    @
    QLock::lock(): Identifier removed
    QLock::unlock(): Unlock without corresponding lock
    QLock::lock(): Identifier removed
    QLock::unlock(): Unlock without corresponding lock
    QLock::lock(): Identifier removed
    QLock::unlock(): Unlock without corresponding lock
    @

    Is this something I should be concerned about? Is this caused by running several qws:es? Or should I look for the error somewhere else?

    Thanks
    /Emil



  • It does seem to be a problem, after a while one of the screen freezes. My guess is that the process deadlocks. It's been a while since I compiled Qt, and I don't have the config files. But from what I can see in my qconfig.pri it seems like most of the things are enabled. Does anyone have any advice on what to look for?

    Hello kottkungen, I know this is an old post
    but did you solve this? I have exactly same configuration with two QWS applications
    on different fbs and exactly same error messages.

    Thank you for your help
