Building B2G requires quite a few libraries installed. For one, we need the ones listed here: https://github.com/mozilla-b2g/b2g#linux and https://developer.mozilla.org/en/Mozilla/Boot_to_Gecko/B2G_build_prerequisites#Requirements_for_Linux On top of this, there are a bunch of 32-bit libraries we need to install, but there is no canonical list of these libraries :( We tend to discover what we need by running the build script and seeing where it fails...

I did make a list of libs needed on Amazon EC2 VM's, here: https://intranet.mozilla.org/Auto-tools/B2G_Automation/Setting_Up_Amazon_VMs Naturally, this list will be different on different linux distributions, and is subject to change at any time.

We're working on pulling all the stuff from the b2g repositories into snapshots that we can use. Extra dependencies will be specified in the mock configs for these jobs.

NB - the any additional dependencies should be installed into the mock environment, and not onto the machine. These will be part of the mozharness configs for the b2g builds.

I think we have what we need here.
