Setup
We're going to be using Yocto. You probably want to refer to: http://www.yoctoproject.org/docs/current/yocto-project-qs/yocto-project-qs.html
The first part of this setup just repeats that.
Choose a directory for git sources, and a different directory for builds. I use: /src/ for git checkouts, and /src/build for builds.
Get a Yocto checkout:
cd /src git clone -b edison git://git.yoctoproject.org/poky.git
mkdir -p /src/build/gnomeos cd /src/build/gnomeos . oe-init-build-env
If you want at this point, you can run 'bitbake core-image-minimal' and you'll get an image bootable in QEMU. However, our next step is to set up the gnomeos layer on top.
You'll need a checkout of ostree:
cd /src git clone git://git.gnome.org/ostree
Now, edit /src/build/gnomeos/build/conf/layers.conf
Add /src/ostree/gnomeos/yocto as a layer. I also recommend editing conf/local.conf and doing the following:
- remove tools-profile and tools-testapps from EXTRA_IMAGE_FEATURES
- choose useful values for BB_NUMBER_THREADS, PARALLEL_MAKE
