Ok, I found this one:It seems, that xlocale.h should not be used as an include, and glibc removed that.So this is ok.The question is if this issue was addressed by icu4c, so we can just go to the next step, or should we do something about this.2017-12-03 23:04 GMT+01:00 Gábor Boskovits <boskovits@gmail.com>:I've found that simply reverting the update to icu4c 60 commit brings up the issue you just mentioned, with missing xlocale.h.So it seems, that the one you found introduced the xlocale problem, while 4e080fbb0bb73e4444181599676f4e1ef5fdc2ba introduces the new error. I think we should deal with the one you find first, the see what's with this newer one.We also have a long running discussion on a bug introduced by a later glibc update, ee3ebf1a357bd4eb36a2fa1790a7b549cffb305a which broke a lot of packages. Might these be somehow related? 2017-12-03 22:46 GMT+01:00 Chris Marusich <cmmarusich@gmail.com>:Gábor Boskovits <boskovits@gmail.com> writes:

After about 2 days of running git bisect, my computer has informed me
that the first bad commit is 67d527e35e367c9e9e89ec01cda2ce32cabd2d89.
This is the first commit where icu4c fails to build on core-updates.
The build failure at this commit is as follows:

Note that this is NOT the same error as the one that occurs at commit
d6adba786cf2ab1b26ff083928b64262281ff106 (which is the commit on
core-updates from which Gábor's branch change-default-icedtea-8 branch
begins). That error is:

The fact that these errors are different suggests that more than one
problem may have been introduced...
I haven't tried any more recent commits on core-updates. I am not sure
what the best way is to debug this, so I would appreciate any advice
anyone has.
I hope that information helps. Hopefully, together, we can untangle
this!
