can't compile minimal example for wasm32-unknown-unknown

cargo web build --target wasm32-unknown-unknown --verbose

produces error: linking with lld failed: exit code: 1 and = note: Unknown flavor: wasm.

• rustc 1.27.0-nightly (056f589fb 2018-04-07)

Works for me; I'm using the same versions of everything as you do.

What's your OS?

And does this reproduce when you build with vanilla cargo? (The resuling artifacts will be useless, but it should link properly.)

Can you try to delete the examples/target directory and try again?

NixOS

Here's the same issue :(

It's the same. Probably it's an issue with NixOS but which one?

[koute]

My guess would be that either:

a) the Rust's copy of LLD on NixOS was inadvertently built without WASM support,
b) or Rust on NixOS uses system LLD which was build without WASM support

You might want to try to install Rust through rustup (although I don't know if that's possible on NixOS?) and see if it reproduces too.

If it's really a NixOS-specific report then reporting a bug on NixOS bug tracker would be appropriate here.

rustup didn't work for while in NixOS but I just tried it again an it seems to work :)
Thanks for your help!
