In a project that's worked 3 weeks ago, now i'm seeing the below error. This is reproducible in a bare bones cargo project. (llvm pkg-config opencv are installed.)

  1. Operating system: macOS
  2. The way you installed OpenCV: package, official binary distribution, manual compilation, etc.: homebrew
  3. OpenCV version: 4.2.0_3
  4. Attach the full output of the following command from your project directory:

Binding generator was completely rewritten in version 0.30, so that must be a regression. Have you tried building with --features buildtime-bindgen? You'll need libclang for that (e.g. from homebrew's llvm package).

Thanks, I could prob. help out too, if I'd knew how to run the last command "c++" "-O0" manually, or sth... Is there a staging dir? Thanks anyways...

Those commands are run in the general cargo out directory of the crate build, in your case it's /Users/ben/dev/rust/test2/target/debug/build/opencv-ff70dd177048d86f/out/, but the hash is different for different crate version and feature sets.

Looks like there are many errors. I can't seem to make sense of any specific one... Maybe its some wrong compiler version?

c++ --version 00:02:08
Apple clang version 11.0.0 (clang-1100.0.33.17)
Target: x86_64-apple-darwin19.3.0

Have you tried building with --features buildtime-bindgen?

Yes thanks, that actually made it work: features = ['opencv-4', 'buildtime-bindgen']
Both in my test and regular project!

Good to hear! I'm still going to try to update the default bindings so that they don't include this non-portable declaration
