Nix build fails: line 729: /build/makeself.khG0YkK0/zstd: cannot execute: required file not found

[micimize]

It looks like the build fails due to some issue extracting the drivers

I am very much a Nix noob, so there is probably a better way of fixing this, but I was able to fix this on my system with the following patch:

The above diff didn't work for me, but figured the following out:

Update the ./utils/GetNixGL.sh file as such:

Seems to be almost working.

[TimVosch]

@kimabjorkede Looks like that specific driver version is not available. Try upgrading the driver on your host system.

Also check here for versions available:
https://download.nvidia.com/XFree86/Linux-x86_64/

But be warned, Simula most likely won't run - even if it compiles. The GLIBC dependency of your OpenXR Runtime will be too new for Simula, as Simula uses an almost 1,5 year old version.

[Cyrus-Harding]

I just got an nvidia driver that's in https://download.nvidia.com/XFree86/Linux-x86_64/, it seems to be able to continue longer, but it still ends up in an error:

Using @Delamare2112 's patch it gives a shorter error message:

@kimabjorkede
Unfortunately, I won't be able to be much of help.

The Shorter error is shorter because it can't find the "nvidia driver flake", so it wont even try to compile. However, in both cases there is an xapp-gtk3-module error. It is either a consequence of the driver not being able to be installed, or it is a separate dependency missing.

I'd first try to solve the driver issue before focusing on the xapp-gtk3-module error.

One thing I notice is that it is trying to install Nvidia Bumblebee. This is usually for notebooks with both an integrated GPU and a dedicated GPU.
You might try to bypass it to only use your dedicated GPU, but that might require changes to your OS setup and/or the flake.

Good luck!

[Cyrus-Harding]

I think I'll give up until someone properly fixes this.

It's a shame as Simula looks really cool!

[TimVosch]

@kimabjorkede IIRC the devs are mainly focusing on getting the headset hardware and fabrication worked out before continuing on the software. So I expect issues like these will be addressed sooner or later :)

Hi fellows.

The solution by [Delamare2112](#192 (comment)) seems to work for me on current Arch.

Mean while, I am now bumping on:

so have to figure out how to add correct glibC version.
