| Additional Information | I have tried the following by chatgpt and couldn't solve the issue: Ensure X Server is Running: If you are using WSL (Windows Subsystem for Linux), you need to have an X server running on your Windows machine. You can use software like VcXsrv or Xming. Download and install one of these, then start the X server. Set DISPLAY Environment Variable: Set the DISPLAY environment variable in your WSL environment to point to your Windows machine's IP address. You can do this by adding the following line to your ~/.bashrc file and then sourcing it: bash نسخ الكود echo "export DISPLAY=$(grep nameserver /etc/resolv.conf | awk '{print $2}'):0" >> ~/.bashrc source ~/.bashrc Run the Application: Try running your application again to see if the issue is resolved. If the application still fails to start, we can try reinstalling the Qt platform plugins: bash نسخ الكود sudo apt-get install --reinstall qt5-default Check Qt Plugin Path: Ensure the Qt plugins are in the correct path. You can add the following lines to your ~/.bashrc file if needed: bash نسخ الكود export QT_QPA_PLATFORM_PLUGIN_PATH=/usr/lib/x86_64-linux-gnu/qt5/plugins/platforms export QT_PLUGIN_PATH=/usr/lib/x86_64-linux-gnu/qt5/plugins Verify Plugin Directory: Verify that the xcb plugin is located in the expected directory: bash نسخ الكود ls /usr/lib/x86_64-linux-gnu/qt5/plugins/platforms You should see libqxcb.so among other plugins. Check Permissions: Ensure that the directory and files have the correct permissions: bash نسخ الكود sudo chmod -R 755 /usr/lib/x86_64-linux-gnu/qt5/plugins Run a Simple Qt Application: Try running a simple Qt application to verify that Qt itself is functioning correctly. You can create a basic Qt application or use an existing one to test. If you still encounter issues after these steps, please provide any additional error messages or logs for further assistance. Ensure X Server is Running on Windows If you're using WSL (Windows Subsystem for Linux), make sure you have an X server running on your Windows machine. You can use VcXsrv or Xming. Here's how to proceed with VcXsrv: Download and Install VcXsrv: Download VcXsrv from here and install it on your Windows machine. Run VcXsrv: After installation, launch VcXsrv with the following options: Select "Multiple windows" Check "Start no client" Check "Disable access control" Set DISPLAY Environment Variable in WSL Ensure the DISPLAY environment variable is set correctly in your WSL environment. Edit .bashrc: Open your .bashrc file: bash نسخ الكود nano ~/.bashrc Add DISPLAY Export: Add the following line to set the DISPLAY variable: bash نسخ الكود export DISPLAY=$(grep nameserver /etc/resolv.conf | awk '{print $2}'):0 Reload .bashrc: Apply the changes: bash نسخ الكود source ~/.bashrc Check for X Server Connection Verify that you can connect to the X server from your WSL environment. Test X Server Connection: Install x11-apps to use xeyes for testing: bash نسخ الكود sudo apt-get install x11-apps Run xeyes to check if the X server connection works: bash نسخ الكود xeyes If the xeyes application opens, your X server connection is working correctly. Run Your Qt Application Again Try running your Qt application again: bash نسخ الكود cd ~/qt-test ./qt-test Additional Troubleshooting If the application still fails, ensure the Qt platform plugins are correctly set up: Check Qt Plugin Path: Ensure the QT_QPA_PLATFORM_PLUGIN_PATH is set correctly: bash نسخ الكود export QT_QPA_PLATFORM_PLUGIN_PATH=/usr/lib/x86_64-linux-gnu/qt5/plugins/platforms Check Permissions: Ensure the plugin directory has the correct permissions: bash نسخ الكود sudo chmod -R 755 /usr/lib/x86_64-linux-gnu/qt5/plugins Verify Plugin Directory: List the contents of the plugins directory to ensure libqxcb.so is present: bash نسخ الكود ls /usr/lib/x86_64-linux-gnu/qt5/plugins/platforms If you still encounter issues, please provide any additional error messages or logs for further assistance. | ||||

What is the content of the file "~/.bashrc"? Namely, what does the following command give you? cat ~/.bashrc Because from the error message that you are getting, the wrong commands were used to install OpenFOAM 11 and/or possibly there was an attempt to install OpenFOAM 12. Furthermore, why is there a mention to 'root' as well? What does the command above give you when you run it as root? |
