| Note that right now, Launchpad can only be built and run on Ubuntu (8.04 "Hardy" to 9.04 "Jaunty").

| $ mkdir ~/launchpad $ cd ~/launchpad $ bzr --no-plugins cat http://bazaar.launchpad.net/~launchpad-pqm/launchpad/devel/utilities/rocketfuel-setup > rocketfuel-setup $ chmod a+x rocketfuel-setup $ ./rocketfuel-setup ## This will take a while -- maybe a few hours to get everything, ## depending on your Net connection. ## ## Note that you will be prompted for your 'sudo' password, and for ## a Launchpad login ID. The sudo access is necessary to get ## Launchpad running on your box; the Launchpad.net login is not ## strictly necessary, and you can just hit Return there if you ## want; see below for an explanation. ## ## Note that this will make changes to your Apache configuration if ## you already have an Apache server on your box. It will also add ## entries to /etc/hosts and it will setup a postgresql server on ## you box. ## If you want to play safe with regards to your existing Apache, ## try this out in a virtual environment first. ## TODO: Make sure this list is complete! $ ls lp-branches/ lp-sourcedeps/ $ cd lp-branches ## You are now in a newly-created Bazaar repository, with one ## branch ('devel'), into whose working tree the other ## source dependencies have been symlinked. The sourcedeps ## actually live in ../lp-sourcedeps, though. $ ls devel/ ## That's it! That's your Launchpad trunk. |

| == What the Installation Process Does == The '''`rocketfuel-setup`''' script first determines what release of Ubuntu you're running, then installs various lines into files under '''`/etc`''', to enable you to run Launchpad services locally. For example, it adds entries for "launchpad.dev", "bazaar.launchpad.dev", "lists.launchpad.dev", and others to your '''`/etc/hosts`''' file, so that after you build launchpad you can browse to '''`launchpad.dev`''' and see a locally-running instance. It also installs some packages, dependencies that Launchpad needs in order to run. This is why the sudo access is necessary; consult the script for details of what it's doing. Once it's got the system preparation out of the way, the script initializes a Bazaar repository (that's the '''`lp-branches`''' directory above), and pulls down a development trunk ('''`lp-branches/devel`'''). That will take a while. After it gets that, it fetches the other dependencies, the third-party libraries, by invoking a separate script, '''`lp-branches/devel/utilities/rocketfuel-get`'''. That will take a while too, as there are almost thirty such libraries. Once it has all the dependencies, it links them into the trunk working tree, using the script '''`lp-branches/devel/utilities/link-external-sourcecode`'''. |

Overview
Launchpad is a core of service-specific code surrounding various third-party libraries, some of which are installed. So the process of fetching Launchpad to build it looks something like this: grab the core code, grab all the libraries, unpack them into the right places in the tree, and then build the whole thing.
Fortunately, we've written scripts to take care of most of that, and instructions on using those scripts are below.
Launchpad's branches are hosted in Bazaar, using the 2a repository format -- currently the best available. That means you'll need to use at least Bazaar 1.18.1 or preferably 2.0 to get Launchpad. Recent Ubuntu releases contain a sufficient new version of Bazaar.
The source tree is about 150Mb, although the total size of the repository you'll download is about 280Mb, as you're getting the full history with it.
Getting It
To build and run a Launchpad development instance, see Running. If you just want to grab the trunk source code branch:
bzr branch lp:launchpad
To learn about alternative "trunk" branches, see Trunk.
