Example code in README leads to linking errors #137

Closed amw-zero closed 3 years ago

amw-zero commented 3 years ago

Following the example code in the README for calling Rust from Ruby led to the following error for me:

error: could not compile `rutie_ruby_example`

MacOS version 10.15.7 Rutie version 0.8.1 Ruby version 2.7.2 (compiled with --enable-shared). rustc version 1.48.0

This error means that the Rust --> Ruby bindings have not linked (i.e. here) the Ruby C library.

I noticed that the example app in the repo does not specify the no-link cargo feature, and removing that feature from my example app allowed rutie to compile.

amw-zero commented 3 years ago

I have a PR for the removal of no-link from the example app code's Cargo.toml here: https://github.com/danielpclark/rutie/pull/136

Thanks for tagging me in this.

amw-zero commented 3 years ago

I’ve opened issues before where the maintainer did not get a notification automatically. Hopefully that didn’t come off as pushy, and if it did I apologize.

danielpclark commented 3 years ago

Not pushy at all. I don't get notifications unless I'm tagged or following something. It was, and is, a sincere thanks.

danielpclark commented 3 years ago

@amw-zero Just out of curiosity what OS are you using?

amw-zero commented 3 years ago

This happened to me on MacOS version 10.15.7.

danielpclark commented 3 years ago

@amw-zero Can you try it with Rutie v0.8.2 ? The build script previously had issues if rutie is included with a relative path. I don't know if that's how you were including it.

I have made it so that the no-link option is not on by default as I believe it was causing more problems for users than it was helping... but the option is still there. If this is no longer an issue please feel free to close the issue.
