Transcript: from git checkout to qemu desktop
From Yocto Project
Jump to navigationJump to search
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.

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: http://yoctoproject.org/documentation For more information about OpenEmbedded see their website: http://www.openembedded.org/ 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.

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...

### 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/src/Yocto/build$ bitbake poky-image-sato
Pseudo is not present but is required, building this first before the main build
