Cannot get distcc/pump to work

graysky · 2012-12-19 23:59:13

I have two machines on a GigaLAN both running distccd.
1) Workstation (Intel i7-3770K) with 8 logical CPUs.
2) Laptop (Intel C2D) with 2 logical CPUs.

On my workstation:

% cat /etc/distcc/hosts
localhost/9,cpp,lzo
192.168.0.102/3,cpp,lzo

On my laptop:

% cat /etc/distcc/hosts
localhost/3,cpp,lzo
192.168.0.101/9,cpp,lzo

Just the workstation
Here is just the workstation

% make -j8 bzImage  496.11s user 25.67s system 712% cpu 1:13.26 total

Trying to use pump/distcc
On the laptop...

% eval pump --startup

On the workstation...

% eval pump --startup

% pump make -j12 bzImage CC=distcc

Love to figure out what's going wrong.

Note that I can use makepkg to build using just distcc (no pump mode) just fine.

/etc/makepkg.conf
MAKEFLAGS="-j12"
BUILDENV=(distcc fakeroot color !ccache check !sign)
DISTCC_HOSTS="localhost/9 192.168.0.102/3"
