Re: Unable to build tools from netbsd-6-0 branch on 7.99.36/7.99.42



And of course, this is not really a new problem.  See

http://mail-index.netbsd.org/current-users/2016/05/08/msg029334.html

and the related thread for details and work-around.

Is there some reason why we shouldn't commit this?

I was looking into some other (irrelevant) issue, and wanted to try and build a 6-0 release.

Using the command

	./build.sh -T /build/netbsd-6-0/tools/x86_64/amd64 \
	-D /build/netbsd-6-0/dest/amd64 -O /build/netbsd-6-0/obj/amd64 \
	-R /build/netbsd-6-0 /release -V RELEASEMACHINEDIR=amd64 -V \
	MKKDEBUG=yes -U -m amd64 -j1 -U tools

It gets most of the way through, then fails on building gcc. The first error message is

My build host is running a 7.99.42 kernel from yesterday, with a 7.99.36 userland.

Any clue on what's broken?

I was reminded on irc that tools build allows errors, so the above is not the real problem.

A short while further down the log file, I do find a real error:
