Add RUSTFLAGS="--cfg=engine" before that command and you should be good. Setting a .cargo/config.toml as described in the new work-in-progress docs should also work.

That said, I'd be willing to create a perseus cargo .. command that lets these sorts of things be done more easily, since you should really run them for --cfg=client as well.

For anyone just searching the error, this error also happens if you update Perseus without updating the cli.

cargo install perseus-cli --version 0.4.0-beta.16

[arctic-hen7]

@rwdj oh yes, currently the CLI is undergoing some major updates as well, so it needs to be kept in sync fully with whatever version you're using. Post v0.4.0 going stable however, that shouldn't be so much of a problem anymore.

[rieval]

I updated to beta.17 and followed the docs to create the .cargo/config.toml. Everything seems to be working fine. Hurray for you!

[arctic-hen7]

@rieval glad to hear! Since adding that file is now strongly recommended and works for this sort of thing, it's probably not worth creating a perseus cargo command (especially since cargo rustc would probably confuse the flags quite a bit).
