[gentoo-user] Problem with distcc and pump mode: failed to connect to unix-domain: Permission denied

[Uwe Scholz]

Hello Gentoo fellows :-)

I have a mysterious problem with distcc and pump mode. Actually, distcc
is working here, but together with pump mode I get strange error
messages and can't find a solution for it.

For example I tried to install minitube on my notebook (the distcc
client) by

pump emerge minitube

In the output of the make process for nearly every new file which should
be processed the error message

distcc[2815] ERROR: failed to connect to UNIX-DOMAIN /tmp/distcc-pump.boOiEs/socket: Permission denied
distcc[2815] (dcc_build_somewhere) Warning: failed to get includes from include server, preprocessing locally

occurs. So, if I get this right, pump mode is not used. Distcc itself is
working, as my other PC is compiling something for the client, but I
want to understand why pump mode is not used...

/tmp/distcc-pump.boOiEs/socket is owned by root as you can see here:
ls -l /tmp/distcc-pump.boOiEs/socket
srwxr-xr-x 1 root root 0 10. Okt 09:55 socket

The file /etc/distcc/hosts on my client looks like
uwe-notebook/8,cpp,lzo 127.0.0.1/1 
where uwe-notebook is the distccd server.

In both /etc/portage/make.conf on the client and the server side I have 
FEATURES="preserve-libs sandbox ccache distcc parallel-fetch"
CCACHE_CPP2=1
CCACHE_DIR="/var/tmp/ccache"

The CFLAGS are not set to native for both machines but to nocona on the
client and to core2 on the server side, as distcc is not working for
native.

Can anyone give me a clue?

Ciao,
Uwe

I just want to inform you all that I solved the problem with distcc and
pump-mode. FEATURE="distcc-pump" was missing in my make.conf. With this
entry no further errors occur.

Ciao,
