Using distcc

Posted on 25, May 2013

For Debian, on your local machine as well as the build nodes:

sudo apt-get install distcc distcc-pump

On the build nodes:

distccd --daemon --jobs <n procs> --allow <local machine ip>

Indicate to your local machine where to find the build nodes, IP addresses space separated with options comma separated. If you are building C++ the lzo option is required:

export DISTCC_HOSTS='<node1 ip>,cpp,lzo <node2 ip>,cpp,lzo'

If you are using CMake for example, you will want to set both CMAKE_CXX_COMPILER and CMAKE_C_COMPILER to /usr/lib/distcc/c++ and /usr/lib/distcc/cc respectively before configuring your build. Now you are ready for a distributed build:

distcc-pump make -j<n procs across all nodes>
pump make -j<n procs across all nodes>


It seems the package in the Debian repository is not properly configured, and one may encounter this error or similar:

__________Using distcc-pump from /usr/bin
__________Using 1 distcc server in pump mode
/usr/bin/distcc-pump: 1: /usr/bin/distcc-pump: /usr/bin/ not found
/usr/bin/python: can't open file '/usr/bin/include_server/': [Errno 2] No such file or directory
__________Expected a socket at '/tmp/distcc-pump.dsNg8o/socket'
__________Could not start distcc-pump include server

To fix, in /usr/bin/distcc-pump , aroud line 43 set include_server :
