Honestly I would just try to patch it out to be "noop" (always assume toolchain it tries to "check" is fine) and see if it builds. i already deleted build.rs and then it fails because there was no wasm output | 12:56:46 |
| cleverca22 | and patching it to remove the check, i dont think will work, its just going to run cargo on the real wasm project, and then fail the same as dummy-crate | 12:57:15 |
 Gaétan Lepage | What is the best way to reference release/target/x86_64-unknown-linux-gnu/release/ in the checkPhase for instance? | 13:27:45 |
| Gaétan Lepage | Is there a shell variable containing this? | 13:27:53 |
 Alyssa Ross | There is a variable for the system part | 13:39:58 |

How does it fail? Cannot compile the WASM runtime: no standard library sources found at /nix/store/0rn3apgrjdqrq6zpqsrh5b8dmlxbci42-rustc-1.85.0/lib/rustlib/src/rust!
i gave it an ldd, and now it cant find the standard library | 13:48:05 |

There is a variable for the system part I ended up using cargoInstallHook.targetSubdirectory | 14:03:35 |

| cleverca22 | ah wait, it wants the SOURCE for wasm32! | 14:11:34 |
| cleverca22 | K900: any ideas? | 14:14:40 |
 K900 | It should be the same source always | 14:14:53 |
| cleverca22 | ls: cannot access '/nix/store/0rn3apgrjdqrq6zpqsrh5b8dmlxbci42-rustc-1.85.0/lib/rustlib/src/rust': No such file or directory | 14:15:09 |
| cleverca22 | its looking in here for wasm32 | 14:15:14 |
| cleverca22 | but its only in $out//lib/rustlib/wasm32-unknown-unknown/ | 14:15:32 |
| cleverca22 | in a pre-compiled form | 14:15:37 |
| Alyssa Ross | Why does it need source? | 14:18:09 |
| cleverca22 | In reply to @qyliss:fairydust.space
Why does it need source? no idea, but thats what the error said:

 tobi34 | It seems that https://github.com/nix-community/fenix.git does not have the current rust stable version 1.86.0. Is there a workaround to get rust 1.86.0 with fenix ? | 19:20:12 |
| K900 | It should presumably update after the fix that was just merged | 19:22:06 |
| tobi34 | I have looked at the last commit, it seems to have fixed some vscode problem. I didn't see a change for updating to 1.86.0 (I am very new to nix, so I'm not sure). In the issues page there is a call for a new maintainer. | 19:34:45 |
| K900 | That change fixes the automatic CI workflow | 19:39:36 |
| K900 | That updates the Rust versions | 19:39:40 |

| Pol | Hey, I would like to package my first Rust project to Nixpkgs, but there are flaky test when tests are ran by the checkphase within Nix. | 07:49:50 |
| Pol | You can see the package here: https://github.com/NixOS/nixpkgs/pull/397142/commits/dccd2f8cf6e64985393fb6f04ee2d12c763af0a8 | 07:50:31 |
