[distcc] distcc doesn't read /etc/distcc/hosts when started by rpmbuild

[Yassine ILMI]

Hi Sam,

1 - From my understanding, distcc is looking for its configuration from
environment variables (for the current session) or for a config file
located in $DISTCC_DIR/hosts directory -
http://distcc.googlecode.com/svn/trunk/doc/web/man/distcc_1.html#TOC_15

2 - I'm not sure how distcc handle configuration from files depending on
distributions, you should also run "distcc-config" utility. More
information about distcc configuration keys here :
http://distcc.googlecode.com/svn/trunk/doc/web/man/distcc_1.html#TOC_22

3 - I prefer to configure distcc using environment variable directly in a
file and source it when needed. You should check if the session used to run
rpmbuild also have distcc environment variables set.

Cheers,
Yassine
