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.

The Yocto Project has extensive documentation about OE including a reference manual
which can be found at:

You had no conf/bblayers.conf file. The configuration file has been created for
you with some default values. To add additional metadata layers into your
configuration please add entries to this file.

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