Blocking installation problem on Mac M1

[Microraptoria]

Hello!

While trying to install it on a Mac 15.0 Sequoia (M1 Chip) with Rust 1.83.0, I've faced the following error:

--- stdout
  MacOS detected. We will check if you have either the MacPorts or Homebrew package managers.
  Checking for MacPorts...
  Macports not found.
  Checking for Homebrew...
  'brew' executable detected at "/opt/homebrew/bin/brew\n"
  Proceeding with installation assuming Homebrew is your package manager

  --- stderr
  thread 'main' panicked at /Users/blep/.cargo/registry/src/index.crates.io-6f17d22bba15001f/rsmgclient-2.0.2/build.rs:101:14:
  called `Result::unwrap()` on an `Err` value: Os { code: 2, kind: NotFound, message: "No such file or directory" }

After investaging a bit by myself, I was able to fix it "quickly and dirty" by tweaking your code. When looking at the aforementioned file (build.rs), I get:

let mut openssl_dirs = std::fs::read_dir(PathBuf::new().join(path_openssl))
            .unwrap()

(a bit more about this later). Just above, I see that you check the installation of OpenSSL:

let path_openssl = if cfg!(target_arch = "aarch64") {
            "/opt/homebrew/Cellar/[email protected]"
        } else {
            "/usr/local/Cellar/[email protected]"
        };

I've changed from [email protected] to openssl@3 (which is installed on my machine). Note that for MacPorts you check the installation of openssl3. So, I bypassed the error. 😁

Anyway, the error comes from the fact that std::fs::read_dir returns a Result that you bypass using an unwrap. So, if [email protected] is effectively not installed on the client's machine (which was the case for me), it explodes. 💥

Moreover, even if it's not recommended, if I try to install [email protected] through brew, I get:

Error: [email protected] has been disabled because it is not supported upstream! It was disabled on 2024-10-24. 

Hence the blocking error. 🙂
