Error with Qt when opening SOFA (QOpenGLWidget)

I faced the following error when running SOFA on my Ubuntu 24.04 where I downloaded SOFA v24.06 and Qt version 6.6.3 :

[WARNING] [Qt] QOpenGLWidget: Failed to create context
[WARNING] [Qt] composeAndFlush: QOpenGLContext creation failed
[WARNING] [Qt] composeAndFlush: makeCurrent() failed
[WARNING] [Qt] composeAndFlush: makeCurrent() failed
[WARNING] [Qt] composeAndFlush: makeCurrent() failed
[WARNING] [Qt] composeAndFlush: makeCurrent() failed
[WARNING] [Qt] composeAndFlush: makeCurrent() failed

To fix this, all what is needed is to specify :

export LD_LIBRARY_PATH=/home/hugo/Documents/Qt/6.6.3/gcc_64/lib/

where the path where I downloaded Qt is : /home/hugo/Documents/Qt/6.6.3/

If you want it to be persistent, add /home/hugo/Documents/Qt/6.6.3/gcc_64/lib/ to your PATH (in ˜/.bashrc for example)
