UE compile failures on latest nix

1

Hello, Im a artist that works in both film and games. I need UE5 to work. ive moved over to nix as ive seen some awesome things, and i really love the way its immutable and can shift from hardware to hardware.

My issue is that, i cannot get UE5 to compile. when i get to the run the “./Setup.sh” im presented with errors from bash. Specifically “bash: ./Setup.sh: cannot executte required file not found”

I have mono installed "the version that was availble to nix-env -i mono
then i install clang again with nix-env -i clang
then i pulled the repo and ran the Setup.sh

i cannot get past this issue. Im looking forward to working with this os, its very promising and this so far is the only issue i have come across beside a few hardware issues (mostly solved)

If any one could help me get ue5 compiled and running i would be extremely greatful. Thank you in advanced

Is Setup.sh starting with #!/bin/bash ?

Installing development dependencies using nix-env is not supported. Use nix-shell instead. See also I installed a library but my compiler is not finding it. Why?

As for the Setup.sh error, NixOS intentionally does not have /bin/bash (recently discussed in Shebang locations) so you will need to replace this line with #!/usr/bin/env bash.

I’d love to know if you managed to get UE5 to compile.
