I am trying to use distcc to distribute the compilling work of an gentoo laptop to an server that also have Gentoo installed.

Here is the info of the laptop which runs distcc:

emerge --info
Code:

emerge --info

The above info are all from guest (the laptop). It is found that the server has received the compilling job via distccd. here is the output on the server:

Can anyone please shed some light on this issue? thanks very much.

-------------------------update -------------------------------
interestingly, when I make the setup reversed (i.e., PC becomes client that runs distcc, laptop becomes server that runs distccd, the job is able to be distributed from the client to the server), the compilling work can be successfully distributed from client to server. but during the compile, there are still some warnings:

pump emerge g++

For me, compiling gcc, g++, etc hasn't ever made use of distcc. They don't get along well apparently. The difference is that, on my system, it doesn't even try to use it. Perhaps the ebuild for the new version of gcc doesn't disable distcc like it should? Might be worth looking.

I use distcc extensively here. It's true that most of gcc doesn't use distcc, but some parts do, such as compiling mpc, etc. I think it's locked to MAKEOPTS="-j1" too, at least much of it. At least here in Funtooland. I concede that our gcc ebuilds are different.
I have this env variable:
Code:
DISTCC_DIR=/var/tmp/portage/.distcc
I don't have DCCC_PATH at all.
Regarding this error:
Code:
distcc[8725] (dcc_set_trace_from_env) ERROR: failed to open logfile /home/chenming/distcclog: Permission denied
you need to change the ownership on that log file, this one works here:
Code:
-rw-r--r-- 1 distcc  root    1432649335 Nov  6 08:58 distccd.log
Yes, it's for distccd, but same thing. Woo, that puppy's getting pretty large, better clean it up. So you see, I do use distcc alot...
This error:
Code:
distcc[8728] ERROR: failed to connect to UNIX-DOMAIN /tmp/distcc-pump.fPQj5w/socket: Permission denied
seems to be that pump is being run by a different user than the emerge process. Have you tried simply running pump emerge from the command line, rather than 1st starting pump --startup? Else I guess it's google time, obviously it's not going to work while you have that error. I've had it before too, don't recall how I fixed it, except to get everything right :wink: And of course, the man files, distcc, distccd, pump and include server.
I run pump on a couple of ARM devices, best I've got for you.

This is of no use to anyone, but I happily use distcc on gcc and gclib with -j3. I did once have a problem compiling gclib with distcc, but it turned out I'd upgraded distcc, and lost the symlinks to the wrapper function described in the Distcc/Crossdev guide.
