[Swift CI] Build Failure: 0. OSS - Swift Incremental RA - Ubuntu 16.04 (master) #897

Development CI Notifications

We keep seeing this failure in the bots:

src/libdispatch.so: error: undefined reference to ‘_T0s17_assertionFailures5NeverOs12StaticStringV_SSAE4fileSu4lines6UInt32V5flagstFTfq4nxnnn_n'

A clean build fixes it. However, it comes back, because if the bot builds the 4.0 branch and then goes and builds master, the problem returns.

Hmm, just so I understand what is going on here ... is there an
incompatible change and we aren't rebuilding enough stuff (possibly a
missing dependency?) or is there something else going on? Sounds like the
swift portion of the build needs to be more aggressively rebuilt?

I think that PR308 on libdispatch should help with that. I don’t have CI
rights on that repository though.

Hmm, just so I understand what is going on here ... is there an
incompatible change and we aren't rebuilding enough stuff (possibly a
missing dependency?) or is there something else going on? Sounds like the
swift portion of the build needs to be more aggressively rebuilt?

+Saleem, who's been looking at Dispatch's build system.

We keep seeing this failure in the bots:

src/libdispatch.so: error: undefined reference to
‘_T0s17_assertionFailures5NeverOs12StaticStringV_SSAE4fileSu4lines6UInt32V5flagstFTfq4nxnnn_n'

A clean build fixes it. However, it comes back, because if the bot builds
the 4.0 branch and then goes and builds master, the problem returns.

Can somebody look at this?
