 Jack Leightcap | hey all -- i'm packaging a rust project, and noticed that nixpkgs doesn't include oxalica/rust-overlay: i'm curious then if there's a way to add targets to rustc inside nixpkgs, something like in a rust-toolchain.toml targets = [ "thumbv7em-none-eabihf" ] | 03:01:12 |
| Jack Leightcap | the context is an embedded firmware, so the target platform is fixed to arm-embedded. would pkgsCross.arm-embedded accomplish this? | 03:05:10 |
 ghpzin | Pretty sure this exact target is covered by something related to cross in rust section in nixpkgs. | 04:26:18 |

| Jack Leightcap | thanks, RTFM needed and useful here | 04:38:57 |
| ghpzin | Does anybody know if there are workarounds for Cargo.lock having dependencies with same name, but different urls ?

(other than editing Cargo.lock to use same one and hoping for the best) | 06:24:01 |

| Theo Paris | So building a rust crate for mingw with llvm ends up trying to cross compile rustc and cargo for mingw instead of just the rust crate... What would be the correct fix for this? Additionally, building x86_64-w64-mingw32-rustc fails due to dlltool | 04:09:22 |

 K900 | How are you doing that? Also, why LLVM? | 04:10:19 |
| Theo Paris | (import nixpkgs {
system = "x86_64-linux";
crossSystem = {
system = "x86_64-windows";
rust = {
rustcTarget = "x86_64-pc-windows-gnu";
};
};
}).pkgsLLVM.pkgsCross.mingwW64

| Theo Paris | If I set useLLVM and linker to lld in crossSystem instead of outside crossSystem, it fails to build compiler-rt-libc. | 04:11:32 |
| Theo Paris | * If I set useLLVM and linker to lld in crossSystem instead of outside crossSystem, it fails to build compiler-rt-libc, probably because it tries to use lld flags with lld-link | 04:12:12 |
| K900 | Yeah this is very wrong for a variety of reasons | 04:14:21 |
| K900 | What are you trying to achieve here | 04:14:28 |
| K900 | Do you want MinGW or MSVC | 04:14:37 |
| Theo Paris | I am trying to cross compile a rust crate with mingw and LLVM. | 04:14:55 |
| K900 | This makes no sense because MinGW is GNU | 04:15:30 |
| K900 | So do you want MinGW or LLVM | 04:15:37 |
| Theo Paris | I wanted mingw because its posix | 04:15:46 |
| K900 | Then why is LLVM even there | 04:16:00 |
| Theo Paris | Because I want to use llvm tools and clang instead of gcc | 04:16:19 |
| K900 | Why? | 04:16:45 |
| Theo Paris | If there is a way to uses clang/lld-link to cross compile without mingw then I have no idea what that way would be. | 04:16:55 |
