Qt 6.7.2 tools suddenly stopped working

Tom asso

I’m running Qt 6.7.2 on ubuntu 22.04.3. I installed Q6 6.7.2 in HOME with the online installer tool. Somehow my installed Qt tools have stopped working. E.g. qtcreator now fails with:

% qtcreator
qtcreator: $HOME/Qt6/Tools/QtCreator/bin/../lib/Qt/lib/libQt6Core.so.6: version `Qt_6.7' not found (required by $HOME/Qt6//6.7.2/gcc_64/lib/libQt6DBus.so.6)

I get the same error for qtdesignstudio.
I get the same error if I execute directly from qtcreator bin/ directory:

% cd $HOME/Qt6/Tools/QtCreator/bin
./qtcreator
./qtcreator: $HOME/Qt6/Tools/QtCreator/bin/../lib/Qt/lib/libQt6Core.so.6: version `Qt_6.7' not found (required by $HOME/Qt6/6.7.2/gcc_64//lib/libQt6DBus.so.6)

My PATH and LD_LIBRARY_PATH are set as follows:

% echo $PATH
$HOME/Qt6/Tools/QtDesignStudio/bin:$HOME/Qt6/Tools/QtCreator/bin:$HOME/Qt6/6.7.2/gcc_64/bin:/usr/lib/ccache:/opt/gcc-arm-none-eabi-10-2020-q4-major/bin:$HOME/.local/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games:/snap/bin:/snap/bin:$HOME/.local/bin

% echo $LD_LIBRARY_PATH 
$HOME/Qt6//6.7.2/gcc_64/lib:

These failures are mysterious, as the tools were working last time I tried them several weeks ago, and I don't know what relevant changes I've made to my system.

Thanks!

Hi,

Why are you setting LD_LIBRARY_PATH like that ?

@SGaist - I am almost sure LD_LIBRARY_CODE was set that way when tools were working. But I unset LD_LIBRARY_PATH and now the tools are working! Thanks!
