godot-rust is not working on macos (using dylib and not dll)

[ghost]

I am following the hello world example on macos. I have followed all the steps but i keep getting an error:

Error loading GDNative file res://bin/warbath.dylib: GodotEngine v4.* is not yet supported. See #396

i am using godot 3.5 stable, godot-rust 0.10.0, rustc version 1.62.1

i am guessing that it is because i am trying to use a dylib instead of dll. but macos rust only produces dylib.

Since you're using Godot 3.5, can you check if #910 works for you?

You can use that branch as follows:

[dependencies]
gdnative = { git = "https://github.com/Bromeon/godot-rust.git", branch = "feature/godot-3.5" }

[lib]
crate-type = ["cdylib"]

It worked!!

Thank you so much

Happy to hear that, and thanks for trying that branch!
Every person testing it increases the confidence in our Godot 3.5 support 🙂

Any ideas how i can automate the build and import to godot? having to copy lib files after editing gets difficult with multiple files and frequent changes.

[Bromeon]

The gdnlib path can refer to something outside the Godot repository, e.g. res://../rust/target/debug/game-logic.dylib.
This way, you don't need to copy lib files, but you may need to minimize (not close) Godot when you build Rust.

Note that this only works during development -- once you export your Godot project, the res:// path needs to refer to libraries inside.

You can also further automate things with bash scripts, for example:

# assuming you have this directory strucure:
# 
# game/
#   godot/
#      project.godot
#   rust/
#      src/
#      target/
#      Cargo.toml

# godot is an alias/symlink to the Godot executable
cargo build --manifest-path rust/Cargo.toml && godot --path godot

Also don't hesitate to join our Discord server in case of further questions 🙂

Edit: updated Discord link

Hey. The invite is not working

[Bromeon]

@hirohido I just tried my link and get to the Discord page, and asked about account details. If I randomly change the link, it tells me the invitation is invalid. What error do you get?

That said, that link is pretty ancient and I could probably create a new one.

It works now. Thanks
