What does this error mean "undefined symbol: _ZNK14QWidgetPrivate17hasHeightForWidthEv"
-
Hi
I've written a gui program and when I want to run it the qt will display the following error
@symbol lookup error: /usr/lib/x86_64-linux-gnu/libQtOpenGL.so.4: undefined symbol: _ZNK14QWidgetPrivate17hasHeightForWidthEv
/home/mahyaits/MahyaSoftware/MahyaITS-build-desktop-Qt_4_8_1_in_PATH__System__Debug/MahyaITS exited with code 127@and it exits without launching the application ... I've searched most of the available forums and tried different solutions but none worked out for me ....
what does this mean ? I'm working with qt 4.8 and there's only 1 version of qt installed in my pc ...
