Configuring OpenEmbedded - This section is a stub, help us by expanding it + At this point, your $OEBASE/ directory should + contain at least the following subdirectories: + + build/ + bitbake/ + openembedded/ + + + +
Environment Setup + There are a few environment variables that you will need to set + before you can build software for OpenEmbedded using BitBake. You will + need to set these variables every time you open a terminal for + development. You can automate this in + ~/.profile, /etc/profile, or + perhaps use a script to set the necessary variables for using BitBake. + + + Since the path to your OpenEmbedded installation will be used in + many places, setting it in your environment will allow you to use + the $OEBASE variable in all pathes and make it + easier to change in the future should the need arise. To + set $OEBASE if you use a Bourne like shell + + If you use a CSH like shell (e.g. on a FreeBSD system), you + will set environment variables like this: + +$ setenv VAR_NAME "VAR_VALUE" + + , do this: + + +$ export OEBASE=/path/to/your/oe/installation + + + + If you followed the recommendation to use BitBake from svn, you + will need to add the path to the BitBake executable to + your PATH environment variable like this: + + +$ export PATH=$OEBASE/bitbake/bin:$PATH + + + In order for bitbake to find the configuration files for + OpenEmbedded, you will need to set the BBPATH + variable. + + +$ export BBPATH=$OEBASE/build:$OEBASE/openembedded + + + Finally, if you wish to allow BitBake to inherit + the $OEBASE variable from the environment, you will + need to set the BB_ENV_EXTRAWHITE variable: + + +$ export BB_ENV_EXTRAWHITE="OEBASE" + + Note the absence of the "$" character which implies that you are + setting BB_ENV_EXTRAWHITE to the variable name, not + the variable value. + +
+ +
Local Configuration + It is now time to create your local configuration. While you could + copy the default local.conf.sample like this: + + +$ cd $OEBASE +$ cp openembedded/conf/local.conf.sample build/conf/local.conf +$ vi build/conf/local.conf + + It is actually recommended to start smaller and + keep local.conf.sample in the background. Add + entries from there step-by-step as you understand and need + them. Please, do not just edit + build/conf/local.conf.sample but + actually READ it (read it and then edit it). + + + For building an org.openembedded.dev branch, in + your local.conf file, you should have at least + the following three + entries: BBFILES, DISTRO + and MACHINE. For example, consider the following + mininal local.conf file for the Ångström + distribution and the Openmoko gta01 machine: + + +BBFILES = "${OEBASE}/openembedded/packages/*/*.bb" +DISTRO = "angstrom-2008.1" +MACHINE = "om-gta01" + +
