Unable to build docs

[jturner314]

When I try to build the docs (latest master, version 85bfae5) with cargo doc (Rust 1.30.1 on x86_64-unknown-linux-gnu), I get an internal compiler error. Is anyone else experiencing this, or is it just me? I don't see any other issues about this.

The fix was merged into rust already but is only available for nightly build. You can build nalgebra docs on nightly.

See rust-lang/rust#55690

Okay, thanks. I tried stable, beta, and the nightly I had already; I should have tried updating nightly. I can confirm it works with the latest nightly.
