Being a member 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_. +If you want to run more than one instance of the build farm to test multiple different configurations, such as one with OpenSSL and one with GnuTLS, simply start at step 9. More details on the extra configuration required to keep it separate from the main build are at the end of this page. + ## 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. 2. Create the master exim user (i.e. the user that Exim changes uid to when it runs in normal operation). I suggest the user **exim**. If you already have the Exim package provided by your distro installed, chances are good that you already have a user named **exim** or **exim4**. That user is fine.

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.
