To reproduce builds:

 (1) Download the br-reproduce-build script at
     http://git.buildroot.net/buildroot-test/plain/utils/br-reproduce-build

 (2) Run ./br-reproduce-build <hash of the build>

     The <hash of the build> is for example
     0ae6ca0b278ca1903057ff6ac31b1b70e8638b9a in
     http://autobuild.buildroot.net/results/0ae6ca0b278ca1903057ff6ac31b1b70e8638b9a

Otherwise, you can do that manually. In every build result directory,
such as
http://autobuild.buildroot.net/results/0ae6ca0b278ca1903057ff6ac31b1b70e8638b9a,
you have a file called "gitid" that contains the Buildroot commit at
which the build was done, and a file called "config" that contains the
Buildroot configuration.

So essentially, what the br-reproduce-build script does is:

$ git checkout $(curl http://autobuild.buildroot.net/results/0ae6ca0b278ca1903057ff6ac31b1b70e8638b9a/gitid)
$ make clean
$ curl http://autobuild.buildroot.net/results/0ae6ca0b278ca1903057ff6ac31b1b70e8638b9a/config > .config
$ make

Best regards,

Thomas
