Description

• This contribution represents a trivial change (skip the following sections).
• This contribution represents a CI/CD change that needs to be tested e2e (skip the following sections; justify below).

Addition of a Nix flake

Motivation and Context

Added Nix flake to allow us to create reproducible development environments for subnet.

Changes Made

The changes consist of a flake.nix and a supporting expression avalanche-network-runner.nix which builds an environment to test and simulate subnet

Testing

Using nix develop I was able to check that avalanchego and avalanche-network-runner are in the path

Seems like the NIX_LDFLAGS needs to be set prior to line 83?

When I run nix develop inside m1 on linux ubuntu I get this error:

error:

I feared that may happen as I was unable to easily run this on a x86_64 system. I will now and get back with an update.

Looks more like a name resolution issue from the logs.

Adding this here as a note to self, but the nix shell will need these cargo deps. No need to add now.

cargo install cargo-binstall
cargo binstall cargo-risczero
cargo risczero install
