CCACHE & DISTCC
After a successfull ccache and distcc packages merge, and after issuing the commands:
| Code: At the shell prompt |
$ env-update && source /etc/profile |
you must have a PATH environment variable looking like this:
| Code: At the shell prompt |
$ echo $PATH /usr/lib/ccache/bin:/usr/lib/distcc/bin:/usr/local/bin:/usr/bin:/bin:/opt/bin:/u sr/i686-pc-linux-gnu/gcc-bin/3.3.6:/opt/blackdown-jdk-1.4.2.02/bin:/opt/blackdow n-jdk-1.4.2.02/jre/bin:/usr/qt/3/bin:/usr/games/bin |
Check to see if you also have the following environment variables (just as samples):
| Code: At the shell prompt |
$ echo $DISTCC_HOSTS localhost 10.2.1.122 10.2.1.125 10.2.1.126 10.2.1.132 10.2.1.11 $ echo $CCACHE_DIR /home/me/.ccache |
Tip: If you don't have some of the above environment variables, check the manpages or other HOWTOs about ccache and distcc .
Scons
Then, you only need to add lines like the ones below to make your scons builds use object caching and distributed compilation:
| Code: SConstruct segment |
if os.path.exists('/usr/lib/distcc/bin'):
os.environ['PATH'] = '/usr/lib/distcc/bin:' + os.environ['PATH']
env['ENV']['DISTCC_HOSTS'] = os.environ['DISTCC_HOSTS']
if os.path.exists('/usr/lib/ccache/bin'):
os.environ['PATH'] = '/usr/lib/ccache/bin:' + os.environ['PATH']
env['ENV']['CCACHE_DIR'] = os.environ['CCACHE_DIR']
env['ENV']['PATH'] = os.environ['PATH']
env['ENV']['HOME'] = os.environ['HOME']
|
and call scons with the option -j n, with n being the number of distccd servers, including your localhost
That's it.
