The OpenEmbedded build system provides several example
|
||
|
|
images to satisfy different needs.
|
||
|
|
When you issue the <filename>bitbake</filename> command you provide a “top-level” recipe
|
||
|
|
that essentially begins the build for the type of image you want.

Building an image without GNU General Public License Version 3 (GPLv3),
|
||
|
|
GNU Lesser General Public License Version 3 (LGPLv3), and the
|
||
|
|
GNU Affero General Public License Version 3 (AGPL-3.0) components
|
||
|
|
is only supported for minimal and base images.
|
||
|
|
Furthermore, if you are going to build an image using non-GPLv3 and
|
||
|
|
similarly licensed components, you must make the following changes in
|
||
|
|
the <filename>local.conf</filename> file before using the BitBake
|
||
|
|
command to build the minimal or base image:
|
||
|
|
<literallayout class='monospaced'>
|
||
|
|
1. Comment out the EXTRA_IMAGE_FEATURES line
|
||
|
|
2. Set INCOMPATIBLE_LICENSE = "GPL-3.0 LGPL-3.0 AGPL-3.0"
