Which Package for Freecad

Help
1

There are 3 packages for Freecad:

https://search.nixos.org/packages?channel=25.05&from=0&size=50&sort=relevance&type=packages&query=freecad

Assuming that freecad-wayland is for GNOME.

But freecad-wayland and freecad crashes sooner or later…

Why do you assume that?

It’s a Qt app.

Anyway, if it’s crashing, share the logs…

I think I am running into the same issue as they are. Regardless of which of the three freecad packages I use, the program crashes with a segmentation fault whenver I try to open a file or create a new project. One example for the crash is below. Here I started freecad and clicked on the first example project:

Unfortunately, that backtrace is missing debug info. Try using enableDebugging for that package; see here: Debug Symbols - NixOS Wiki

Thanks for the information. I shall start debugging…

As a temporary solution I have activated Flatpak…

{ config, pkgs, ... }:

{
  home.packages = [

    # Flatpak
    pkgs.flatpak
    pkgs.gnome-software

   ];
}

Just saw, that Freecad 1.0.2 is available. NixOS has version 1.0.1.

Does it make sense to wait with debugging?

Looks like there’s already a bug report about this: freecad: segfault when opening file · Issue #429237 · NixOS/nixpkgs · GitHub

In the meantime, I found that running FreeCAD as COIN_EGL=1 freecad works for me.

Freecad 1.0.2 is drafted in freecad: 1.0.1 -> 1.0.2 by LordGrimmauld · Pull Request #431206 · NixOS/nixpkgs · GitHub.
The file opening issue has been fixed in freecad: apply patch fixing crash on wayland by NickCao · Pull Request #434105 · NixOS/nixpkgs · GitHub, in the meantime COIN_EGL=1 freecad should work (or forcing x11 via QT_QPA_PLATFORM=xcb freecad)

freecad used to default to the qt5 build (and still does on stable 25.05). On that build, it defaulted to x11 rendering. The three packages were qt5 (x11), qt5 (wayland), and qt6 (supported both). Because of the way stable works, we can’t backport the removal of the qt5 versions, but the qt6 version is arguably the one that should be used. The crashes need backporting of the coin fix, which i can look into.
