5 years ago @jappeace I don't understand what's the purpose of this. What exactly is the problem you are solving? Do you want to be able to build HyperNerd using only nixpkgs?
I just made default.nix give me native dependencies like zlib/openssl and I just build everything using only cabal https://github.com/tsoding/HyperNerd#nixos Had way too many problems with nixpkgs.

5 years ago I had problems with dependency resoultion, for example discord haskell got pulled in to the newest version on hackage. Which was incompatible with your code.
These changes create a shell with the exact version I believe you're using by pinning them to the git reversion used by upstream. For example this is the 0.8.3 release as tracked by git for discord haskell. And this pins all of the nixpkgs dependencies to a version I guessed you were using based on dates.

5 years ago @jappeace this doesn't clarify anything to me. Please provide detailed steps on how you try to build the project.

5 years ago Hi,
I followed the instructions in the readme to the letter now, being sure of myself I'd encounter an error, but alas, I must have deviated at some point wasting a bunch of my own time and some of yours.
I'm sorry.
in the default.nix import { } is used,
this uses the host os'es nixpkgs rather than selecting a specific
one.
In my case this would pull in various erronious libraries. It also couldn't find louis or discord-haskell so I also added those.
Pinning this down should make the libraries the same for anyone using this.
Most of this code is generated by cabal2nix, I just hooked it together and played with revisions untill I got a working build.
Cheers. - jappiejappie.
