I want to run sweethome3d (nixpkgs rev 057f9aecfb71c4437d2b27d3323df7f93c010b7e) but run into
Caused by: com.jogamp.opengl.GLException: Profiles [GL4bc, GL3bc, GL2, GLES1] not available on device null
This old thread had the same issue years ago:
The difference is that I am running NVIDIA
$ glxinfo -B
name of display: :0
display: :0 screen: 0

What I don’t understand is that I do use MESA drivers for OpenGL in my NixOS config
$ nix repl
Welcome to Nix 2.18.1. Type :? for help.
nix-repl> flake = __getFlake (toString ./.)
nix-repl> flake.outputs.nixosConfigurations.tosaka.config.hardware.opengl.package.pname
"mesa"
and
$ find /run/opengl-driver/lib -name '*mesa*'
/run/opengl-driver/lib/libGLX_mesa.so.0
/run/opengl-driver/lib/libEGL_mesa.so.0.0.0
/run/opengl-driver/lib/libGLX_mesa.so.0.0.0
/run/opengl-driver/lib/libGLX_mesa.so
/run/opengl-driver/lib/libEGL_mesa.so.0
/run/opengl-driver/lib/libEGL_mesa.so
The package for sweethome3d on nixpkgs seems to assume that MESA OpenGL is used and can be used to override OpenGL version.
I guess I can either
- try to force NVIDIA to use another OpenGL version (could not find about it on the web)
- try to force sweethome3d to use MESA instead of NVIDIA (I have no idea how)
Would anyone know about it?
