distcc and portage

[CatSC]

Hello.
At the moment I'm trying to setup distcc.
I think distcc itself is working cos if I do
$ cd /usr/srs/linux
$ make bzImage -j3 CC=distcc
it distributes tasks and compiles properly.

my /etc/make.conf looks like

Code: Select all

CFLAGS="-O2 -mcpu=i686 -fomit-frame-pointer"
CHOST="i386-pc-linux-gnu"
USE="kde gtk"
CXXFLAGS="${CFLAGS}"

MAKEOPTS="-j5 CC=distcc"
FEATURES="distcc"
DISTCC_HOSTS="main localhost"

when I try emerge something it says
"distcc[13047] ERROR: compile on localhost failed"

Cna you plz help me?

[cylgalad]

MAKEOPTS="-j5" is enough, emerge ccache and have a FEATURES="distcc ccache", and don't forget to use distcc-config
You MUST read : http://www.gentoo.org/doc/en/distcc.xml

Thanks

Ok I have it working now... the problem was that I thought that I have GCC of same version on both comps, but I didn't.

But there's other little problem. "distcc Monitor" does not show anything...
I'm sure that distcc itself is working properly cos I can see cc1 processes started by distccd on my main comp.

Do you know how to fix it?

CatSC:

In some guide somewhere it said to launch the graphical monitor with the env var as such:

Code: Select all

DISTCC_DIR=/var/tmp/portage/.distcc nohup distccmon-gnome &

and the text version as such:

Code: Select all

DISTCC_DIR=/var/tmp/portage/.distcc distccmon-text 1

Hope this helps

So using the above hint on executing distcc-gnome worked for me...also if you check in /var/tmp/portage/.distcc there should be two directories state and lock. When it wasnt working for me on one of my boxes I noticed that lock was missing so I unemerged it and rememerged it and it ran just fine after that so if your having problems might check that directory and then reemerge....El

Couple of noob questions about distcc:
Firstly which computer can i run the monitor on to see something happening (as neither seem to show much )?
And secondly what is a good program to emerge to test this as i'm emerging kde at the mo (it's an update so thought i might as well) and it doesn't seem to have done anything (i've only give it 10 mins on a Pentium3 700 but still)?
Cheers

You can run the monitor on the pc that you begin the emerge on ie the computer you are actually installing the software on. VSFTPD seems to use DISTCC consistently. So I would emerge it see if I see any activity and then unmerge it to test distcc with. Also as a sanity check I run netstat -c -A inet on either computer and look for traffic on port 3632 which is what distcc uses. If you are seeing that traffic it is working! Also running top -u distcc is somewhat useful just to make sure the program is actually running. Hope this helps. El

i get this error when trying to run distccmon-text the way you said:

Code: Select all

root # DISTCC_DIR=/var/tmp/portage/.distcc distccmon-text 1
distccmon-text[26968] (dcc_mkdir) ERROR: mkdir /var/tmp/portage/.distcc/state failed: No such file or directory
