Problem with libQt5Core.so.5

[Nikita_Pas]

Hi everyone.
I get the following error when running projects:

$ cmake -DGeant4_DIR=/home/name/geant4-v11.2.1-install/lib/Geant4-11.2.1 ../B1
...
$ make
..
[100%] Built target exampleB1
$ ./exampleB1
./exampleB1: error while loading shared libraries: libQt5Core.so.5: cannot open shared object file: No such file or directory

The ldd command showed the following:

$ ldd ./exampleB1 | grep -i qt 
/libQt5Core.so.5 => not found 
/libQt5OpenGL.so.5 => /lib/x86_64-linux-gnu/libQt5OpenGL.so.5 (0x00007f44d0770000)
/libQt5Widgets.so.5 => /lib/x86_64-linux-gnu/libQt5Widgets.so.5 (0x00007f44cff90000)
/libQt5Gui.so.5 => /lib/x86_64-linux-gnu/libQt5Gui.so.5 (0x00007f44cf990000)
/libQt5Core.so.5 => not found
/libQt5Core.so.5 => not found
/libQt5Core.so.5 => not found
/libQt5Core.so.5 => not found
/libQt5Core.so.5 => not found
/libQt5Core.so.5 => not found

But this file is on the system:

$ find /lib/ -name  libQt5Core.so.5
/lib/nsight-compute/host/linux-desktop-glibc_2_11_3-x64/libQt5Core.so.5
/lib/nsight-systems/Host-x86_64/libQt5Core.so.5
/lib/x86_64-linux-gnu/libQt5Core.so.5

I installed everything:

$ sudo apt-get install g++ cmake cmake-curses-gui build-essential expat libx11-dev libxmu-dev libexpat1 libexpat1-dev libqt4-dev libglu1-mesa-dev freeglut3-dev mesa-common-dev
$ sudo apt-get install qt5-default qtbase5-dev libqt5quickcontrols2-5 libqt5multimedia5 libqt5webengine5 libqt5quick5 libqt5qml5 qtchooser qt5-qmake qtbase5-dev-tools

The solution with the “$ source /home/name/geant4-v11.2.1-install/bin/geant4.sh” does not help.
I also tried to re-build Geant4 after installing all the libraries with the conditions below, but the problem remains.

$ sudo cmake -DCMAKE_INSTALL_PREFIX=../geant4-v11.2.1-install ../geant4-v11.2.1 -DGEANT4_INSTALL_DATA=ON -DGEANT4_USE_QT=ON -DGEANT4_USE_OPENGL_X11=ON -DGEANT4_BUILD_MULTITHREADED=ON -DCMAKE_BUILD_TYPE=Release

I’m using windows 10 with wsl, where:
Geant4 Version: 11.2.1
Operating System: Ubuntu 20.04.6 LTS (on version 22.04.3 the situation is the same)
CMake Version: 3.16.3

Tell me, please, how can I solve this problem?

It’s probably this bug in WSL/Qt: ELF section .note.ABI-tag breaks shared libraries · Issue #3023 · microsoft/WSL · GitHub

See that and related for workarounds.

Thanks for your reply.

I stole the command from your link

$ sudo strip --remove-section=.note.ABI-tag /usr/lib/x86_64-linux-gnu/libQt5Core.so.5 

And got an error with “…libG4graphics_reps.so…”. I fixed it with the command

$ source /home/name/geant4-v11.2.1-install/bin/geant4.sh

After that it showed problems with “Available UI session types: [Qt, tcsh, csh], qt.qpa.xcb: …, qt.qpa.plugin: …”.
Then I got tired of it. I left WSL and just installed Virtual Box with Ubuntu 20. In this implementation, everything worked from the first installation.
