2.2 Installing the code

The Buildbot is installed using the standard python distutils module. After unpacking the tarball, the process is:

     python build
     python install

where the install step may need to be done as root. This will put the bulk of the code in somewhere like /usr/lib/python2.3/site-packages/buildbot . It will also install the buildbot command-line tool in /usr/bin/buildbot.

To test this, shift to a different directory (like /tmp), and run:

     buildbot --version

If it shows you the versions of Buildbot and Twisted, the install went ok. If it says no such command or it gets an ImportError when it tries to load the libaries, then something went wrong. pydoc buildbot is another useful diagnostic tool.

Windows users will find these files in other places. You will need to make sure that python can find the libraries, and will probably find it convenient to have buildbot on your PATH.

If you wish, you can run the buildbot unit test suite like this:

     PYTHONPATH=. trial buildbot.test

This should run up to 192 tests, depending upon what VC tools you have installed. On my desktop machine it takes about five minutes to complete. Nothing should fail, a few might be skipped. If any of the tests fail, you should stop and investigate the cause before continuing the installation process, as it will probably be easier to track down the bug early.

If you cannot or do not wish to install the buildbot into a site-wide location like /usr or /usr/local, you can also install it into the account's home directory. Do the install command like this:

     python install --home=~

That will populate ~/lib/python and create ~/bin/buildbot. Make sure this lib directory is on your PYTHONPATH.
