/usr/lib/x86_64-linux-gnu/libQt5Core.so.5: version `Qt_5.15' not found

Hello, I am being sent a binary file from another machine and when trying to run it I am getting this error: /usr/lib/x86_64-linux-gnu/libQt5Core.so.5: version `Qt_5.15' not found.

Looking in my /usr/lib/x86_64-linux-gnu/ folder I only have up to libQt5Core.so.5.9.5 although I have QT 5.15.1 installed.

Anyone know how I could fix this error?

export LD_LIBRARY_PATH=HERE_PATH_TO_QT_LIBS_DIR && ./my_app

One solution is to properly deploy the app, see https://doc.qt.io/qt-5/linux-deployment.html "Creating the Application Package"
Or you set LD_LIBRARY_PATH to point to your Qt 5.15.1 libs before starting the app.

@jsulm How exactly would I set the LD_LIBRARY_PATH? Would it just be a command line statement where I am equaling it to the 5.15.1 libs?

@m4t1 Did you try

export LD_LIBRARY_PATH=HERE_PATH_TO_QT_LIBS_DIR && ./my_app
