Software projects/OS/Slackware/Advanced usage/Distributed compilation

Get started

• So you need at least two networked Open Pandoras.
• In this exemple, we'll use two OP, OP-1 and OP-2.
• The compilation will be launched on OP-1.
• OP-2 IP adress is 10.0.0.2
• If you connect two OP with an USB cable, be sure to read this.

Distccd server activation

• On both OP, launch as root:

distccd

Setting up the hosts

• On OP-1, open a terminal:

export DISTCC_HOSTS="localhost 10.0.0.2"

Compile

• In the same OP-1 terminal:

make -j4 CC=distcc
make -j4 CC=distcc

• In the -j(n), n represents the (number of CPU used X 2), so if you compile with 10 OP, it will be -j20 .

Monitoring

• You can see how the compilation is distributed.
• As root on OP-1, type:

distccmon-gnome
