Some questions about this result:

1. Is it generally expected that snapshot tags should build on OSX? I thought it would be more likely to build than HEAD. Am I wrong? Is it preferred to build HEAD for general use?
2. Has this issue been fixed? I cannot find a reference to "WARNING: Title underline too short" (which might be the failing error? although the output continues for quite some time) on this list or on bugs.swift.org <http://bugs.swift.org/>, but presumably somebody has tried to build Swift at some point in the past few days
3. Is there something wrong with my config?

Sorry for asking a "hurr durr how to build" question, but I am still getting oriented with the build system and initial searching did not turn up anything relevant to the Swift project specifically.


(Joe Groff) #2

Snapshots and HEAD should always build cleanly on all supported platforms, so we ought to fix this. It may be that our buildbots don't have sphinx installed, so the docs aren't getting checked there. Disabling sphinx in your build config should work around it in the meantime.
