| Florian | W3F | Hi guys. I have been working on a patch for naersk and looking for some feedback. It is based on #167 and uses the additional information provided to only include crates in git-deps that are actually required. | 13:58:11 |

| bernardo | NixOS beginner here. I need to build a Rust crate (https://github.com/paritytech/substrate-contracts-node) that depends on Clang.
I keep running into:
I've tried adding some packages to Home Manager (libclang, llvmPackages.libclang, clang), without success.
I also did a brief google search but I'm quite confused about how to go about this.

 Mark | LIBCLANG_PATH = "${llvmPackages.libclang.lib}/lib"; | 20:12:17 |

LIBCLANG_PATH = "${llvmPackages.libclang.lib}/lib"; I saw this suggestion during my Google search, but I couldn't figure out which file to add this line to. I tried adding it to the same file where my Home Manager definitions are with no success. | 20:13:59 |

It's best to have a separate shell environment for each project, and you can add this in your mkShell | 20:15:26 |
| Mark | ^ | 20:16:10 |
| bernardo | hmm ok so I should write a shell.nix file for this specific project? | 20:16:21 |
| Mark | yes, or flake.nix preferably | 20:16:31 |
| Mark | & echo use flake > .envrc | 20:16:41 |
| bernardo | gotcha... thanks guys! | 20:17:04 |
| Mark | https://github.com/ZentriaMC/neard-nix/blob/master/default.nix | 20:17:15 |
| Mark | and of course flake.nix there | 20:20:51 |
| 23 Jan 2022 |
| bernardo | I'm using this shell.nix: https://github.com/paritytech/substrate/blob/master/shell.nix
applied at the root of this project: https://github.com/paritytech/substrate-contracts-node
I executed $ nix-shell then $ cargo build --release
and now I'm running into:
error[E0658]: use of unstable library feature 'proc_macro_is_available'
I'm guessing there's something missing on the shell.nix file?

What does rustc --version show? rustc 1.57.0-nightly (497ee321a 2021-09-09) | 01:33:38 |

| Zhaofeng Li | Hmm, that feature should exist in that version of nightly (it was removed a month later, which should cause it to complain that the feature is non-existent). Where is that in the code? | 01:36:15 |

= note: see issue #71436 <https://github.com/rust-lang/rust/issues/71436> for more information
= help: add `#![feature(proc_macro_is_available)]` to the crate attributes to enable
| 01:37:15 |
| Zhaofeng Li | Ok, try a newer nightly version where this has already stabilized | 01:39:16 |
