Hello,
A friend of mine needs to run a tool that requires opencl. To help him, I tried to package it locally, and to that end I activated opencl using the following (I have an integrated UHD Graphics 620
):
hardware.opengl.enable = true;
hardware.opengl.extraPackages = with pkgs; [ intel-ocl ];
Now, opencl
seems to work, since I can run clinfo
and get some results:
$ clinfo
Number of platforms 1
[...]
Now, the tool is not trivial to package, so as a first step I run it in a steam-run
environment. However, it turns out that inside the steam-run
environment, clinfo
does not detect it:
$ nix-build -E "with import <nixpkgs> {}; (steam.override {extraPkgs = pkgs: [ocl-icd gnome3.librsvg clinfo]; }).run"
[...]
$ ./result/bin/steam-run bash
bash-4.4$ clinfo
Number of platforms 0
What is the proper way to proceed? I saw that steam has some kind of withPrimus = true;
, but I think that Primus is mostly for dual cards with nvidia
, which is not my case.
Thanks!
