[M3devel] Still can't bootstrap cm3

Rodney,

it's not easy to understand what has gone wrong at this point.
Usually, if you have a working system, cm3/scripts/upgrade.sh
should be able to bootstrap to a new set of sources. This is tested
every day in the tinderbox release tests, too. As the last builds seem
to have succeeded, I don't think there is a real problem in our
code base currently. You may want to have a look at test_build_current
in cm3/scripts/regression/defs.sh to see what's done in the regression
builds.

I'd suggest you either start again from the last release or
one of the latest snapshots available from the build machine.
I assume you are not building a cross compiler, but just trying
to perform an upgrade.

Daily snapshots are available from
http://www.opencm3.net/snaps/snapshot-index.html

I hope this helps,

Olaf
