 This Installation page works on the assumption that you have already submitted your [Exim BuildFarm Application](http://eximbuild.mrball.net/cgi-bin/register-form.pl) and the BuildFarm administration has sent you an email with your machine alias (aka _animal_) and secret password, which you will enter in step 9 below.  If you just want to run the build farm client and never submit the results, you call simply run everything with the --test option and it will still work.  If you ever run it without --test, it will still work, but the server will reject the feedback because it's from an unknown _animal_.

 ## Install Steps
 1. Make sure that all required packages for Exim to build successfully are installed. The minimal package requirements are the basic suite of compiler tools and basic libraries.  You will also need to install the ccache package.

 13. Test the configure process by running `./run_build.pl --test --verbose=2 --only-steps=configure`. If there are errors, you'll need to correct them until the process succeeds (ends with OK).  You can repeat this as many times as necessary because test mode does not store the status of the git repo or the status of each stage of the build.

If there are build errors when building the test suite, or runtime errors trying to run the test suite, you may need to install additional packages (you shouldn't though).

-16. If you enabled the documentation building process in the *build-farm.conf*, then you can try to build it with `./run_build.pl --test --verbose=2 --only-steps=configure,make-doc`.  For documentation generation to succeed, it will require extra packages to be installed to support xml, xslt, pdf, and a few other things.

For documentation generation to succeed, it will require extra packages to be installed to support xml, xslt, pdf, and a few other things. You will need to install packages named **xfpt** and **sdop**. Some prebuilt packages are available for [CentOS 6](http://www.blafasel.at/exim/doc_rpms/) and [CentOS 5](http://downloads.mrball.net/Linux/CentOS/5/RPMS/x86_64/). The packages are available directly on Debian and Ubuntu distros.

 17. If you can get past each of these steps, then your build farm system meets the minimum requirements.
 18. The official process can be kicked off by running `/home/farm/code/run_cron.sh --run-all`.  This will run the default build configuration, keep track of the git repository status, and upload the build results to the server.
 19. Once that command runs with no complaints, add it to the **farm** user crontab.  You can run it at whatever frequency you choose, I suggest 1 hour.  If a previous instantiation is still running, the script will detect the lockfile and exit so as not to step on each other.
