 dotlambda | Is there some way of running cargo build --target=wasm32-wasip1 while building a package for x86_64-linux?

 rosssmyth | Not that I am aware of. You may be able to hack something together with fastCross. But the way the rustc derivation is setup right now makes it hard to just compile a sysroot for a target. | 21:38:12 |
| rosssmyth | * Not that I am aware of. You may be able to hack something together with fastCross. But the way the rustc derivation is setup right now makes it hard to just compile a sysroot for a target without structuring all of your Nixpkgs instance around it. | 21:38:35 |
| rosssmyth | You may be able to do something funny like setting the platforms to a wasi and require people to use pkgsCross.wasi32. But I have no idea what the state of compiling for wasi32 is or if that would work. Would be annoying for end-users though. | 21:41:41 |
 Sandro 🐧 | mitmproxy-linux is cross compiling without anything extra to something wasm | 21:46:52 |
| Sandro 🐧 | *ebpf not wasm | 21:49:53 |
| Sandro 🐧 | your target is missing here https://github.com/NixOS/nixpkgs/blob/master/pkgs/development/compilers/rust/rustc.nix#L158-L161 though | 21:50:09 |
| Sandro 🐧 | maybe this hint https://github.com/NixOS/nixpkgs/blob/master/lib/systems/default.nix#L504 helps | 21:51:07 |
| dotlambda | I would hope that adding something like pkgsCross.wasi32.buildPackages.rustc does the trick | 22:03:08 |
| rosssmyth | Probably will, but that has the downside of instantiating a whole other nixpkgs | 22:03:38 |
| dotlambda | pkgsCross.wasi32 is also used to build Firefox | 22:04:06 |
| dotlambda | In reply to @robert:funklause.de
I would hope that adding something like pkgsCross.wasi32.buildPackages.rustc does the trick Sadly, it fails to build with a complaint about missing a "wasi-root" key in bootstrap.toml | 22:09:51 |
