One thing to note with this example is that I'm checking out from poky/bernard, only because when I created this session, poky/master wasn't building for me.  Normally, you'd want to use poky/master i.e. in the step below where it says 'git checkout -b bernard-cur poky/bernard' you'd want to do 'git checkout -b master-cur poky/master'.  Sometimes it's easier to just use the last known stable version in cases where master is broken and you don't necessarily need master to get your work done.
NOTE: this transcript was from a build done on a Ubuntu 10.04 system.  Please see the 'Yocto Project Quickstart' for the packages required to be installed on the host system for building [http://www.yoctoproject.org/docs/yocto-quick-start/yocto-project-qs.html]

Latest revision as of 16:21, 12 March 2012

Here's a cut-and-paste shell session showing one way to do a start-from-scratch git checkout and build, the end result being a sato desktop in a qemu session (commands also shown for that).

NOTE: this transcript was from a build done on a Ubuntu 10.04 system. Please see the 'Yocto Project Quickstart' for the packages required to be installed on the host system for building [1]

One thing to note with this example is that I'm checking out from poky/edison.

You had no conf/local.conf file. This configuration file has therefore been
created for you with some default values. You may wish to edit it to use a 
different MACHINE (target hardware) or enable parallel build options to take 
advantage of multiple cores for example. See the file for more information as 
common configuration options are commented.

### Shell environment set up for builds. ###

You can now run 'bitbake <target>' 

Common targets are:
    core-image-minimal
    core-image-sato
    meta-toolchain
    meta-toolchain-sdk
    adt-installer
    meta-ide-support 

You can also run generated qemu images with a command like 'runqemu qemux86'


trz@elmorro:/usr/local/dev/Yocto/build$ cd conf
trz@elmorro:/usr/local/dev/Yocto/build/conf$ ls
bblayers.conf  local.conf

Change only the following variables in local.conf, it makes the build go faster depending on how many CPUs you have. I have 4, with HT, so I'm changing my values to 8: 

trz@elmorro:/usr/local/dev/Yocto/build/conf$ emacs -nw local.conf
BB_NUMBER_THREADS = "8"
PARALLEL_MAKE = "-j 8"

Since this is your first build, it won't matter - it will take awhile regardless, but for later builds, to avoid re-downloading all the packages again, you can point the DL_DIR variable in local conf to the downloads dir of a previous build. Continuing the session... 

trz@elmorro:/usr/local/dev$ cd Yocto/
trz@elmorro:/usr/local/dev/Yocto$ source oe-init-build-env

The build succeeded so you can now boot the kernel and rootfs into a graphical desktop:
