Bug 22057 – emerge with distcc fails with: ERROR: unknown host

• Product: Portage Development
• Status: RESOLVED FIXED

[Description Miguel Sousa Filipe 2003-06-01 13:01:04 UTC]

distcc is used successefully in the same computer in things like:
time make CC="distcc" -j5 bzImage

but .. emerge ntp 
does not work.. here is the error
distcc[22653] (dcc_open_socket_out) ERROR: unknown host: "DISTCC_HOSTS=127.0.0.1"
distcc[22653] (dcc_build_somewhere) Warning: failed to distribute to
"DISTCC_HOSTS=127.0.0.1", running locally instead

www linux # echo $DISTCC_HOSTS 
DISTCC_HOSTS=127.0.0.1 193.136.164.1 193.136.164.11

www linux # distcc-config --get-hosts
DISTCC_HOSTS=127.0.0.1 193.136.164.1 193.136.164.11

also noticed that if I did make CC=distcc -j5 bzImage the make would fail with
the same errors.. but make CC="distcc" -j5 bzImage runs very nicely.
also, hostnames aren't working, I only got distcc working with numeric IPv4 host
numbers.

I've seen posts in the forums with ppl having these same problems.. please check
this out guys!

What version of distcc are you using?  Have you tried upgrading to the latest 2.5-r1?  I will be marking that version as stable this week sometime, so please try that to see if these problems are resolved.

Your reported use of 'CC=distcc' also indicates you have probably not read (or have decided to ignore) the Gentoo distcc documentation.  Please view the latest revision on our new development wiki:

http://wiki.dev.gentoo.org/gentoo/moin.cgi/UsingDistcc?action=show

For reference, the original URL mentioned in the ebuild contains mostly the same information, though the wiki is now slightly more up-to-date:

http://cvs.gentoo.org/~zwelch/distcc.html

Try following the suggestions presented there, as well as the linked QuestionsAndAnswers page.  If things remain problematic, please report more of the basic details about your problems, with clear and simple steps to reproduce the problem.  Thank you for using Gentoo.

try:

   unset $DISTCC_HOSTS
   distcc-config --set-hosts "host1 host2 host3"


The problem is you have DISTCC_HOSTS= in the string of hosts, which clearly
is not a valid host.
