ROS Problem: libQt5Core.so.5: cannot open shared object file: No such file or directory

I use this method, from https://answers.ros.org/question/354808/error-running-turtlesim-noetic/.

The key point is to be sure to find the location of your libQtCore, and don't copy others' answers directly.

You could try:

whereis libQt5Core.so.5

copy that address

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

Are you sure that libqt5gui5 is installed? If not, try:

sudo apt-get install libqt5gui5

After installation of the package it should be placed in the proper location that ros could find.

Thank you guys. Below are the steps to solve this problem:

1. Download an X server application for windows because WLS doesn't support graphical interfaces. An example of such X application is Xming (you can download it from https://sourceforge.net/projects/xming/)
2. Type the following command in the WLS terminal: export DISPLAY=:0

Hopefully, this should work!
