Sofa.GL problem

[accuracy-maker]

Dear Community,

I just upgrade my sofa (and all dependencies to v25.12 including SofaPython3, SoftRobot etc). when I run the example in SofaPython3 folder runSofa -l SofaPython3 examples/additional-examples/ControllerScene.py, there is an error:
`[WARNING] [GUIManager] Previously used GUI not registered. Using default GUI.
[ERROR] [SofaPython3::SceneLoader] Unable to completely load the scene from file 'examples/additional-examples/ControllerScene.py'.
Python exception:
ValueError: Object type OglModel<> was not created
The component 'OglModel' cannot be found in the factory.
This component has been MOVED from SofaOpenglVisual to Sofa.GL.Component.Rendering3D since SOFA v22.06.
To continue using this component you may need to update your scene by adding

But the following object(s) exist:
: VisualModel (63% match)

Your scene may not work on a sofa environment with different pre-loaded plugins.
To fix your scene and remove this warning you just need to cut & paste the following lines at the beginning of your scene:
root.addObject('RequiredPlugin', name='Sofa.Component.Engine.Transform') # Needed to use components [TransformEngine]
root.addObject('RequiredPlugin', name='Sofa.Component.IO.Mesh') # Needed to use components [MeshOBJLoader]
root.addObject('RequiredPlugin', name='Sofa.Component.StateContainer') # Needed to use components [MechanicalObject]

The list of available animation loop components is: [AnimationLoopParallelScheduler, ConstraintAnimationLoop, DefaultAnimationLoop, FreeMotionAnimationLoop, MultiStepAnimationLoop, MultiTagAnimationLoop]. A component of type DefaultAnimationLoop will be automatically added for you.

it seeems this simulation works correctly but just the visualisation is broken.

Another clue is that when I run cmake --build $FOLDER_TARGET -j$(nproc) after configure and generate via cmake-gui, it shows that
[100%] Linking CXX shared library ../../../../../../lib/python3/site-packages/Sofa/SoftRobotsInverse.cpython-312-x86_64-linux-gnu.so /usr/bin/ld: cannot find -lSofa.GL: No such file or directory collect2: error: ld returned 1 exit status gmake[2]: *** [applications/plugins/SoftRobots.Inverse/src/SoftRobots.Inverse/binding/CMakeFiles/SoftRobotsInverseBindings.dir/build.make:156: lib/python3/site-packages/Sofa/SoftRobotsInverse.cpython-312-x86_64-linux-gnu.so] Error 1 gmake[1]: *** [CMakeFiles/Makefile2:6598: applications/plugins/SoftRobots.Inverse/src/SoftRobots.Inverse/binding/CMakeFiles/SoftRobotsInverseBindings.dir/all] Error 2 gmake: *** [Makefile:156: all] Error 2

seems there's something wrong with sofa.gl

Other information: I use python=3.12 and WSL2. It works at my previous version sofa v22.06.

Thanks for your time and help.

kind regards,

follow by this, when I run the sofa command with -g, it shows that
[ERROR] [GUIManager] GUI 'qt' creation failed. Available GUIs: {batch}

it should include {qt, imgui} right?

CMake Warning at Sofa/GUI/Common/CMakeLists.txt:61 (message): -- Sofa.GUI.Common: Sofa.GL dependent features disabled.

when I click the configure in cmake-gui

I apologise here coz I post too much today :(.

I feel like I get deeper understanding of cpp, cmake and the source code. I figure it out the solution is clicking SOFA_WITH_OPENGL in cmake-gui and click configure and generate. It's defaulty disabled.

and also remember to install Sofa.Qt.
