@JinShil thanks, that did the trick!

@wilzbach doesn't Walter have a buildkite account?

[WalterBright]

I suppose I could sign up, but I tire of the endless accounts I have (several hundred). I'd like it if buildkite could simply produce a log anyone could read, like the other testers. I confess I don't even know what buildkite is or why we need it.

[jacob-carlborg]

@WalterBright I think you can login with your GitHub account. Buildkite is intended to replace Jenkins.

[jacob-carlborg]

The idea is that it should be public, but Buildkite needs to do that (approve it is an open source project, or something like that). We have asked for that but nothing has happened yet, as far as I know.
