I am reading over the info on distcc so that I might be able to setup an
older P4 1.3 Ghz system to have help compiling from my dual Opteron
(amd64 mode).
I only want the Opteron to help the P4, not the other way around, the
Opteron does not need the help.
Is that configurable as such?
Thanks

Well, http://wiki.kraszewscy.net/Cross_DistCC shows how to do it (in Polish,
sorry).
In short:
---8X---[ setup for COMPILER machine (AMD64) ]-------------------
1. make directory /opt/cross32/bin
2. make there a file "i686-pc-linux-gnu-wrapper" containing
#!/bin/bash
exec /usr/bin/x86_64-pc-linux-gnu-g${0:$[-2]} -m32 "$@"
3. make it executable
4. make soft links in that directory
ln -s i686-pc-linux-gnu-wrapper gcc
ln -s i686-pc-linux-gnu-wrapper g++
ln -s i686-pc-linux-gnu-wrapper c++
ln -s i686-pc-linux-gnu-wrapper cc
ln -s i686-pc-linux-gnu-wrapper i686-pc-linux-gnu-gcc
ln -s i686-pc-linux-gnu-wrapper i686-pc-linux-gnu-g++
ln -s i686-pc-linux-gnu-wrapper i686-pc-linux-gnu-c++
ln -s i686-pc-linux-gnu-wrapper i686-pc-linux-gnu-cc
5. copy "/etc/init.d/distccd" to "/etc/init.d/distccd32"
6. fix "/etc/init.d/distccd32" to have
TMPDIR="${TMPDIR}" \
PATH="/opt/cross32/bin" \
/sbin/start-stop-daemon –start –quiet –startas ${DISTCCD_EXEC} \
7. copy "/etc/conf.d/distccd" to "/etc/conf.d/distccd32"
8. fix "/etc/conf.d/distccd" to have
DISTCCD_OPTS="${DISTCCD_OPTS} --port 3664"
---8X---[ end of setup for COMPILER machine (AMD64) ]-------------------
Now you have two distccd daemons:
* one at port 3632 for 32-bit distcompiling
* one at port 3664 for 64-bit distcompiling
At this point your Opterons will handle remote 32-bit compiling - you don't
need to make any changes on P4 machine other than activating regular distcc.
Thanks Pawel,
Your steps are obviously a bit different then those listed here.
http://www.gentoo.org/doc/en/cross-compiling-distcc.xml
So you are stating just emerge crossdev, the run crossdev -t
and from the point where the web page states "Here is what you want to
do:" (1.2) follow the instructions you listed here, rather then the web
page?
