Getting Buildroot
Buildroot releases are made every 3 months, in February, May, August and November. Release numbers are in the format YYYY.MM, so for example 2013.02, 2014.08.
Release tarballs are available at http://buildroot.org/downloads/.
For your convenience, a Vagrantfile is
available in support/misc/Vagrantfile
in the Buildroot source tree
to quickly set up a virtual machine with the needed dependencies to
get started.
If you want to setup an isolated buildroot environment on Linux or Mac Os X, paste this line onto your terminal:
curl -O https://buildroot.org/downloads/Vagrantfile; vagrant up
If you are on Windows, paste this into your powershell:
(new-object System.Net.WebClient).DownloadFile( "https://buildroot.org/downloads/Vagrantfile","Vagrantfile"); vagrant up
If you want to follow development, you can use the daily snapshots or make a clone of the Git repository. Refer to the Download page of the Buildroot website for more details.
