Create a new directory for the build environment:

Create the directory
$ mkdir $HOME/oe
$ cd $HOME/oe

To be able to download sources from the net, it may be required to configure Proxy Settings.

Now check out the following repositories:

Clone Arago repositories
$ git clone git://arago-project.org/git/arago.git
$ git clone git://arago-project.org/git/arago-oe-dev.git
$ git clone git://arago-project.org/git/arago-bitbake.git

Replace "git" protocol with "http" or "ssh", depending on the required access.

Note: If you know what you are doing, you can try using Arago overlay with upstream OpenEmbedded and BitBake repositories.

The directory should now be populated with 3 subdirectories – arago, arago-oe-dev and arago-bitbake.

Edit arago/setenv file and make sure environment variables are set properly. OEBASE should point to the directory you’ve created in the beginning:

export OEBASE=$HOME/oe

Also, in order to use a separate "scratch" area outside of home directory, you may want to enable SCRATCH variable and point it appropriately:

export SCRATCH=/sim/scratch_AID

Now, source this file to set the environment variables:

$ . arago/setenv

Or alternatively (which is the same, but maybe required if using other shell than bash):

$ source arago/setenv

TI Note: Users of TI RHEL4 systems should also source the arago/ti-rhel4-setenv to set additional paths:

$ . arago/ti-rhel4-setenv

If not done before, set the PATH variable to point to the CodeSourcery toolchain (refer to Getting CodeSourcery Toolchain for obtaining one):

$ export PATH=/opt/arm-2007q3/bin:$PATH

Extract the arago-csl-sdk.tar.bz2 from http://arago-project.org/files/short-term/extras/ on top of the CodeSourcery toolchain (that may require root permissions, depending where CS toolchain was installed):

# tar -jxvf arago-sdk-bins/arago-csl-sdk.tar.bz2 -C /opt/arm-2007q3

Now it should be ready to start a build of the minimal filesystem image:

$ bitbake arago-base-image

Or to build a bigger filesystem with more applications, libraries and tools:

$ bitbake arago-demo-image

To build a kernel, use the following command. Please note, that currently only PSP and linux-omap linux kernels for OMAP3 EVM and linux-omap kernel for BeagleBoard are supported. DaVinci platforms use linux-davinci kernels and also can use linux-davinci-staging, which is a staging area for upcoming features.

$ MACHINE=omap3evm bitbake virtual/kernel
$ MACHINE=beagleboard bitbake virtual/kernel
$ MACHINE=dm6446-evm bitbake virtual/kernel
$ MACHINE=dm355-evm bitbake virtual/kernel

Resulting images and packages will be placed under arago-deploy directory - images for the filesystem, kernel and bootloader; and ipk for binary IPK packages, respectively.
