Content bug: Rust_to_wasm fails to mention Perl and Make

[Dionysusnu]

What page(s) did you find the problem on?

Compiling from Rust to WebAssembly
https://developer.mozilla.org/en-US/docs/WebAssembly/Rust_to_wasm

Specific page section or heading?

https://developer.mozilla.org/en-US/docs/WebAssembly/Rust_to_wasm#wasm-pack

What is the problem?

Installing wasm-pack using cargo requires both perl and make to be installed. These aren't on Windows by default, but nothing is mentioned about it in the guide.

What did you expect to see?

The guide should make mention of this, and recommend how to install both of them. It's a lengthy process though..

Did you test this? If so, how?

I ran into this issue myself, while following the guide.
The error is

error: failed to run custom build command for `openssl-sys v0.9.65`

with some more clutter output lines.
However, no clear problem can be identified from this output. It does mention running a perl script, but it is not at all obvious that it fails because it cannot find perl itself.
This issue for the library shows how unclear the error is: sfackler/rust-openssl#1455

Closed the PR (#9254) as Rust setup docs are more appropriate for documenting this.

[wbamberg]

Yes, closing this, because listing requirements for Rust installation are out of scope for this article.
