[M3devel] HEADS UP: CM3 builds broken

[Olaf Wagner]

Hi again,

the builds I started again this morning before leaving home seem to
have succeeded again. I don't understand why compilation with the
latest sources on my own system was broken though; I'll have to
check that tonight. There's seems to be no immediate need for
action though :-)

It would be great if all committers would check the tinderbox status
on http://www.opencm3.net at least after check-ins. You'll find
it under "Status -> Tinderbox Tests", or directly at
http://tinderbox.elegosoft.com/tinderbox/cm3/status.html.

It contains links to all the build logs and the m3tests and package
build test results, as well as a list of check-ins that may be
responsible for any breakage (click on the dates in the left column).
