I get the following error:

error[E0432]: unresolved import `nix::fcntl`
 --> src/lib.rs:7:10
  |
7 | use nix::fcntl::{flock, FlockArg};
  |          ^^^^^ could not find `fcntl` in `nix`

When I try to compile with cargo build --target wasm32-wasi

We don't target that platform. Would you care to submit a PR to add support?

[antoniomuso]

When I find time, I will be happy to do it.

Have you been able to make it work? WASI/WASM support is the only blocker missing for our usecase as well. However, I do not have the expertise for WASM/WASI/WASIX support. It would be great to have it supported. All other platforms work as expected. Thanks for the info, will check back later.

Do you guys want to use nix on that target or just make the code compile?

To actively target the wasm/wasi/wasix platform which can be run in a WebAssembly runtime, not just to compile. I'd love to ship executables like that, in a hardware-independent format.

Thanks.
