error: could not compile `system-deps` (lib) due to 1 previous error

maybe you already know about this, maybe this is a nightly rust problem and not a system-deps problem, certainly it's not important to me so long as it is happening only on nightly - but I figured I should let you know about it in case work is needed

Thanks for the info, I was not aware of this problem.

That's really strange, why would Library.ld_args be missing with nightly?

@sdroege @amyspark : any idea?

[sdroege]

I don't know. It's always there since pkg-config-rs 0.3.24. Maybe that CI is using an ancient pkg-config-rs version?

[gdesmott]

Good point, we should have bumped the minimal version required!

Looks like it's from 0.3.25 actually.

[dimbleby]

ah yes, I also test with minimal versions - I hadn't realised that was the specific test that was failing

thanks!
