This is a guide on how I compiled an image of Yocto Linux for the Intel Galileo SoC on Arch Linux.
*WARNING*: Arch Linux is not an officially supported build OS for Yocto Linux.
h2. Prepare the Environment Enironment
* Install a few prerequisite packages:
<pre>
sudo pacman -S cpio gawk wget diffstat unzip gcc-multilib texinfo chrpath socat sdl xterm
</pre>
* Install bitbake from the AUR:
<pre>
yaourt bitbake
</pre>
h3. Fix Python environment
* Create a dummy bin folder in the user directory:
<pre>
mkdir ~/bin
</pre>
#* Then add a symlink python to python2 and the config scripts in it:
<pre>
ln -s /usr/bin/python2 ~/bin/python
ln -s /usr/bin/python2-config ~/bin/python-config
</pre>
* Finally put the new folder at the beginning of your PATH variable:
<pre>
echo 'export PATH=~/bin:$PATH' >> ~/.bashrc
</pre>
h2. Prepare the Source Code
* Create a directory for the source code:
<pre>
mkdir ~/git && cd ~/git
</pre>
* Get the latest Yocto version:
<pre>
git clone -b dizzy git://git.yoctoproject.org/poky.git
cd poky
</pre>
h3. Configure Intel BSP
* Get the latest Intel Board Support Packages into the Yocto directory:
<pre>
git clone git://git.yoctoproject.org/meta-intel -b dizzy
</pre>
* Source poky/oe-init-build-env script, giving it the build directory (yocto_build) as a parameter:
<pre>
source oe-init-build-env
</pre>
* Edit @build/conf/local.conf@
<pre>
vi build/conf/local.conf
</pre>
#* And modify the config to match the *genericx86* machine:
<pre>
MACHINE ?= "genericx86"
</pre>
* Add the meta-intel layer to the bblayers.conf file:
<pre>
vi build/conf/bblayers.conf
</pre>
#* And modify the BBLAYERS definition:
<pre>
BBLAYERS ?= " \
/home/user/git/poky/meta \
/home/user/git/poky/meta-yocto \
/home/user/git/poky/meta-yocto-bsp \
/home/user/git/poky/meta-intel \
"
</pre>
h2. Build the Yocto Image
* Run bitbake to build core-image-minimal:
<pre>
bitbake core-image-minimal
</pre>
