FreeCAD AppImage stopped working after Fedora 40 upgrade

After upgrading to Fedora 40, my FreeCAD appimage isn’t working any more. This is the latest FreeCAD release.

It starts and goes through the splash screen / loading plugins, then fails with the following error message:

I’m not sure how to troubleshoot it further. It’s been a while since I’ve run into OpenGL issues.

I am on Workstation 40, using Gnome on X11.
Have been using freeCAD 21.1 appimage and no problems.
I just updated to the 21.2 appimage and it still works with no problems.

I note this on your inxi output

and on mine I see this.

  Display: x11 server: X.Org v: 1.20.14 with: Xwayland v: 23.2.6 driver: X:
    loaded: nvidia unloaded: fbdev,modesetting,nouveau,vesa
    gpu: nvidia,nvidia-nvswitch resolution: 1: 3840x2160~30Hz
    2: 1920x1080~75Hz

Just out of curiosity I switched to wayland and I see this

  Display: wayland server: X.Org v: 23.2.6 with: Xwayland v: 23.2.6
    compositor: gnome-shell driver: X: loaded: nvidia
    unloaded: fbdev,modesetting,nouveau,vesa gpu: nvidia,nvidia-nvswitch
    resolution: 1: 4096x2160~30Hz 2: 1920x1080~75Hz

Note that yours does not show a value for the Display: and mine shows the DE in use with both X11 and wayland. I suspect that solving that part may solve the issue with freeCAD.

I hit the same issue and was able to run FreeCAD using the following command:
LD_PRELOAD=/usr/lib64/ ./FreeCAD-0.21.2-Linux-x86_64.AppImage

This works even though my laptop has Intel graphics.

Hope this helps

I just have to ask. Why would you install an app image of something that is available from the Fedora Flatpak repo or also the rpm repo? It just seems like an invitation for grief to me. The ones in the Fedora Flatpak repo and the traditional Fedora repo are packaged with the appropriate settings for use with Fedora, which is one big step towards a good user experience. I also use FreeCad and do so with the Fedora Flatpak.

RPMs for Fedora 40 (same with 39) are not available for FreeCAD.
AppImage is the format that FreeCAD officially supports and provides, it does not provide flatpack.

Is there an official stable FreeCAD flatpack or FreeCAD + Fedora flatpack source?

If you’re using Gnome Software it can be found in Fedora Flathub selection repo and if you have the Flathub repo installed it can be found there in Beta form. AFAIK the Feora one is from the FreeCad team.

I am using nvidia for my GPU and have never had an issue with the FreeCAD appimage.

Previously freeCAD was available as rpm with f38 but they quit supporting rpm and now actually state that the appimage is the only way forward.

As I understand it, Python 3.11 is supported but Python 3.12 in fedora breaks freeCAD.
f38 initial release contained the rpm in the repo with version 0.20.2 but the current version 0.21.2 does not have an rpm available.

Huh, that fixed it for me. Very strange!
