error: Could not compile `nalgebra`.
warning: build failed, waiting for other jobs to finish...
error: build failed

command that failed:

cargo run --features metal

I am guessing this is fixed in later version of nalgebra?

[msiglreith]

Thanks for the report, I will update the source and migrate towards gfx-hal 0.2

[taylorjdawson]

Thank you! Let me know if you need anymore information. 👍

[msiglreith]

Updated everything please give it a try again. I hope metal still works as I don't have a Mac for testing.

[taylorjdawson]

Thanks! I think there might be one last thing to do? Specify the binary?

❯ cargo run --features metal
error: `cargo run` could not determine which binary to run. Use the `--bin` option to specify a binary, or 
(on nightly) the `default-run` manifest key.
available binaries: ocean, ocean_generator

[msiglreith]

oops, missed to remove the generator again edit: done

[taylorjdawson]

Thanks! what was the bin file for?

[msiglreith]

For generating the static spectrum and frequency values, which where done at runtime before and now stored as binary data on disk (faster startup times)

[taylorjdawson]

Very interesting, thank you! I'll let you know if it works!

This is the next error that arose:

error[E0433]: failed to resolve: could not find `AutoreleasePool` in `back`

[msiglreith]

Thanks for testing! I assume these are not needed anymore, removed

[taylorjdawson]

Wow that worked, this is impressive and will be a great reference. Thanks!
