 typetetris | I have a project with several libs and apps in a single workspace. But I would like to package the apps separately. How do I prevent rebuilds in unrelated apps, if only the source of another app is touched?
Is splitting the repository/workspace the only pragmatic option?
The build system (naersk, cargo2nix, etc ...) would need to be aware of this and only include needed sources, but I am not aware of one doing that. | 08:19:04 |
 dpc | typetetris: You could possibly build the whole workspace, and then use another derivation to copy some binaries from that workspace build. | 18:34:35 |
| dpc | typetetris: Alternatively, crane can run cargo build --bin <cargo-bin> and create a binary out of it, which I use to build single-binary containers, like this: https://github.com/fedimint/fedimint/blob/6624d833de202417da1255759076f4c3f09ac3cf/flake.nix#L179 | 18:35:41 |
| dpc | I imagine cargo2nix and naersk might have similar functionality. | 18:36:11 |

| typetetris | Hmm, would have to try this. But I would expect it to rebuild the single-binary build everytime unrelated sources in the same workspace change. Those build system don't usually filter sources on components to be build. | 05:32:41 |
| typetetris | Of course, that is a very specific requirement. | 05:32:56 |
| typetetris | So it is ok, they don't do this. | 05:33:08 |

 newam | I'm trying to build embedded rust firmware with nix, but not having much success with the recommendations in the rust-section of the nix manual, if anyone here has experience with this I could use some help 😃

 Xe Iaso | how do i make a rust compiler with the wasm32-wasi target enabled? | 16:56:27 |
 a-kenji | I used the oxalica overlay here: https://github.com/zellij-org/zellij/blob/main/.nix/plugins.nix | 16:57:49 |
| a-kenji | This is where the toolchain is specified: https://github.com/zellij-org/zellij/blob/main/rust-toolchain.toml, but i am not quite sure how to do it without an overlay. | 16:59:00 |
| Xe Iaso | :+1: thanks | 17:04:55 |

| dpc | Can I somehow do nix shell nixpkgs#rust-analyzer nixpkgs#openssl nixpkgs#pkg-config github:nix-community/fenix#complete without running nix flake init first?
Basically when I have to temporarily work on Rust project that isn't flakified, I just want to get the dev env working without having some extra files checked in.
| 18:25:00 |
 slby | Yes | 18:25:59 |
| slby | With this syntax you don't need a flake. | 18:26:25 |
| dpc | Oh, I see. I got myself confused then by using .# initially . Thanks. | 18:30:19 |
| slby | And you probably want someting like
nix shell github:nix-community/fenix#complete.toolchain
for enix.
| 18:31:21 |

| 18:31:24 |
| dpc | One last thing nix shell nixpkgs#rust-analyzer nixpkgs#openssl.dev nixpkgs#openssl nixpkgs#pkg-config github:nix-community/fenix#complete.toolchain does not add openssl to PKG_CONFIG_PATH | 18:33:26 |
| dpc | What can I do about it, other than add it manually? | 18:33:55 |
 pennae | use a devShell with all your dependencies in it rather than nix shell | 18:36:46 |
| slby | I am not too sure about that, does it work with nix develop? It doesn't know what kind of input openssl is. so it doesn't prepare it. | 18:37:02 |

 figsoda | I think you would need to set LD_LIBRARY_PATH to make it work with nix develop | 00:54:00 |
| figsoda | nix-shell should work though | 00:54:22 |
