## Using nix-shell ## Working with nix
If you're using nix, you can use the following nix-shell to work on Rust: Several nix configurations are defined in `src/tools/nix-dev-shell`.
```nix If you're using direnv, you can create a symbol link to `src/tools/nix-dev-shell/envrc-flake` or `src/tools/nix-dev-shell/envrc-shell`
{ pkgs ? import <nixpkgs> {} }:
pkgs.mkShell { ```bash
name = "rustc"; ln -s ./src/tools/nix-dev-shell/envrc-flake ./.envrc # Use flake
nativeBuildInputs = with pkgs; [
binutils cmake ninja pkg-config python3 git curl cacert patchelf nix
];
buildInputs = with pkgs; [
openssl glibc.out glibc.static
];
# Avoid creating text files for ICEs.
RUSTC_ICE = "0";
# Provide `libstdc++.so.6` for the self-contained lld.
LD_LIBRARY_PATH = "${with pkgs; lib.makeLibraryPath [
stdenv.cc.cc.lib
]}";
}
``` ```
or
```bash
ln -s ./src/tools/nix-dev-shell/envrc-shell ./.envrc # Use nix-shell
```
