6 | <title>Images</title> | ||
7 | |||
8 | <para> | ||
9 | The OpenEmbedded build system provides several example | ||
10 | images to satisfy different needs. | ||
11 | When you issue the <filename>bitbake</filename> command you provide a “top-level” recipe | ||
12 | that essentially begins the build for the type of image you want. | ||
13 | </para> | ||
14 | |||
15 | <note> | ||
16 | Building an image without GNU General Public License Version 3 (GPLv3) components | ||
17 | is only supported for minimal and base images. | ||
18 | Furthermore, if you are going to build an image using non-GPLv3 components, | ||
19 | you must make the following changes in the <filename>local.conf</filename> file | ||
20 | before using the BitBake command to build the minimal or base image: | ||
21 | <literallayout class='monospaced'> | ||
22 | 1. Comment out the EXTRA_IMAGE_FEATURES line | ||
23 | 2. Set INCOMPATIBLE_LICENSE = "GPLv3" | ||
24 | </literallayout> | ||
25 | </note> | ||
26 | |||
27 | <para> | ||
28 | From within the <filename>poky</filename> Git repository, use the following command to list | ||
29 | the supported images: | ||
30 | <literallayout class='monospaced'> | ||
31 | $ ls meta*/recipes*/images/*.bb | ||
32 | </literallayout> | ||
33 | These recipes reside in the <filename>meta/recipes-core/images</filename>, | ||
34 | <filename>meta/recipes-extended/images</filename>, | ||
35 | <filename>meta/recipes-graphics/images</filename>, | ||
36 | <filename>meta/recipes-qt/images</filename>, | ||
37 | <filename>meta/recipes-rt/images</filename>, | ||
38 | <filename>meta/recipes-sato/images</filename>, and | ||
39 | <filename>meta-skeleton/recipes-multilib/images</filename> directories | ||
40 | within the <ulink url='&YOCTO_DOCS_DEV_URL;#source-directory'>Source Directory</ulink>. | ||
41 | Although the recipe names are somewhat explanatory, here is a list that describes them: | ||

137 | <tip> | ||
138 | From the Yocto Project release 1.1 onwards, <filename>-live</filename> and | ||
139 | <filename>-directdisk</filename> images have been replaced by a "live" | ||
140 | option in <filename>IMAGE_FSTYPES</filename> that will work with any image to produce an | ||
141 | image file that can be | ||
142 | copied directly to a CD or USB device and run as is. | ||
143 | To build a live image, simply add | ||
144 | "live" to <filename>IMAGE_FSTYPES</filename> within the <filename>local.conf</filename> | ||
145 | file or wherever appropriate and then build the desired image as normal. | ||
