How to lunch the app ?

[parweb]

Hello,

I try to follow the docs to try lunatic (https://crates.io/crates/lunatic)

here the code I'm working on
https://github.com/parweb/test-lunatic/

I succeed to build the app after adding extern crate lunatic;
cargo build --release --target=wasm32-wasi

But where I find the binary lunatic ? lunatic target/wasm32-wasi/release/<name>.wasm

The documentations is a bit rough and I will definitely need to improve it. Especially the getting started part.

Lunatic consists of 2 parts:

1. Libraries for different languages - This allows you to generate lunatic compatible WASM files. This is the part you did!
2. The Lunatic runtime - This is the lunatic binary. For now you need to build it yourself. Using rust nightly and doing cargo build --release at the top of this repository should generate it. Don't forget to clone git submodules.

I will also provide pre-built binaries for different operating systems next week when hopefully networking support lands.

I run

git clone --recurse-submodules https://github.com/lunatic-lang/lunatic/
cargo build --release

but got this error

error[E0425]: cannot find function `available_concurrency` in module `thread`
  --> src/lib.rs:35:24

error: aborting due to previous error

For more information about this error, try `rustc --explain E0425`.
error: could not compile `lunatic-vm`

To learn more, run the command again with --verbose.

You will need to use the latest rust nightly. available_concurrency was a recent addition to Rust.

For other newcomers

rustup update
cargo build --release

then
