Hi everyone!

Today, I tried to start an FreeCAD AppImage that I have been using for the last year. But to my surprise, I am treated with this message;

Code:
(qt.qpa.plugin) Could not find the Qt platform plugin "wayland" in ""
(qt.glx) qglx_findConfig: Failed to finding matching FBConfig for QSurfaceFormat(version 2.0, options QFlags<QSurfaceFormat::FormatOption>(), depthBufferSize -1, redBufferSize 1, greenBufferSize 1, blueBufferSize 1, alphaBufferSize -1, stencilBufferSize -1, samples -1, swapBehavior QSurfaceFormat::SingleBuffer, swapInterval 1, colorSpace QSurfaceFormat::DefaultColorSpace, profile  QSurfaceFormat::NoProfile)
(qt.glx) qglx_findConfig: Failed to finding matching FBConfig for QSurfaceFormat(version 2.0, options QFlags<QSurfaceFormat::FormatOption>(), depthBufferSize -1, redBufferSize 1, greenBufferSize 1, blueBufferSize 1, alphaBufferSize -1, stencilBufferSize -1, samples -1, swapBehavior QSurfaceFormat::SingleBuffer, swapInterval 1, colorSpace QSurfaceFormat::DefaultColorSpace, profile  QSurfaceFormat::NoProfile)
Could not initialize GLX


I tried other versions of this AppImage, same thing.
I think I updated this laptop the day before yesterday, so something happened by then.

Something known? Or did I miss some information regarding this?

Does it work if you do:

Code:
export QT_QPA_PLATFORM="xcb"

before starting the AppImage?

No, but different error;

Code:
(qt.glx) qglx_findConfig: Failed to finding matching FBConfig for QSurfaceFormat(version 2.0, options QFlags<QSurfaceFormat::FormatOption>(), depthBufferSize -1, redBufferSize 1, greenBufferSize 1, blueBufferSize 1, alphaBufferSize -1, stencilBufferSize -1, samples -1, swapBehavior QSurfaceFormat::SingleBuffer, swapInterval 1, colorSpace QSurfaceFormat::DefaultColorSpace, profile  QSurfaceFormat::NoProfile)
(qt.glx) qglx_findConfig: Failed to finding matching FBConfig for QSurfaceFormat(version 2.0, options QFlags<QSurfaceFormat::FormatOption>(), depthBufferSize -1, redBufferSize 1, greenBufferSize 1, blueBufferSize 1, alphaBufferSize -1, stencilBufferSize -1, samples -1, swapBehavior QSurfaceFormat::SingleBuffer, swapInterval 1, colorSpace QSurfaceFormat::DefaultColorSpace, profile  QSurfaceFormat::NoProfile)
Could not initialize GLX


Edit: Well, similar, but missing the first
Code:
(qt.qpa.plugin) Could not find the Qt platform plugin "wayland" in ""

line.

That error was also in your first message. My guess, from doing a Web search for "'Failed to finding matching FBConfig' appimage" and results like this, is that changes to the AppImage need to made by the FreeCAD devs. But perhaps someone else can say exactly what the problem is.

(If you're not already aware, app-portage/genlop can be used to list package merges, via `genlop -l`, so that you can review what packages were updated and when.)

I'll see if someone over at FreeCAD community has experienced this.

Thanks

Eventually, I found a branch (link branch), build date yesterday, with a working AppImage. So in a way, it has been solved.

Thanks for suggestions.
