Unable to activate feature "v7" about uuid HOT 6 CLOSED

Since the v6, v7, and v8 features are unstable, you also need to set a RUSTFLAGS environment variable at build-time in order to use them. We've got some docs on that here.

my project was building just fine 3/4 days ago

That makes me think you probably already have that flag set though, so I'll look into it. Maybe something changed upstream in Rust; we haven't made any releases in the last few days.

Glad you got it sorted! For what it’s worth, I can’t wait to get rid of those cfgs once the RFC is stable.

How did I manage to miss that?
Thanks, now everything works as expected.

Hey,

Same here; my project was building just fine 3/4 days ago but today I end up with the same error as you, without any modification of the codebase.

NB: I use uuid 1.4.0, built with Rust 1.70.0 on Debian

I just gave this a test with our example for a v7 sortable UUID using Rust 1.70.0 and 1.71.0 using the RUSTFLAGS cfg and it worked.

Hey,

I have the appropriate rustflags set in a cargo/config.toml file.

I will try again tonight; the fault is likely on my end anyway.

EDIT:

Well, the error was on my end; my cargo/config.toml is not detected for some reason but using the inlined environment variable RUSTFLAGS="--cfg uuid_unstable" cargo build worked like a charm.

EDIT2:
It appears that my cargo/config.toml should be named .cargo/config.toml; I don't know how I made it work few days ago ^^

Sorry for the inconvenience...

Have a nice day :)
