This appendix presents customizations you can apply to the standard SDK.

<title>Adding Individual Packages to the Standard SDK</title>
<para>
When you build a standard SDK using the
<filename>bitbake -c populate_sdk</filename>, a default set of
packages is included in the resulting SDK.
The
<ulink url='&YOCTO_DOCS_REF_URL;#var-TOOLCHAIN_HOST_TASK'><filename>TOOLCHAIN_HOST_TASK</filename></ulink>
and
<ulink url='&YOCTO_DOCS_REF_URL;#var-TOOLCHAIN_TARGET_TASK'><filename>TOOLCHAIN_TARGET_TASK</filename></ulink>
variables control the set of packages adding to the SDK.
</para>
<para>
If you want to add individual packages to the toolchain that runs on
the host, simply add those packages to the
<filename>TOOLCHAIN_HOST_TASK</filename> variable.
Similarly, if you want to add packages to the default set that is
part of the toolchain that runs on the target, add the packages to the
<filename>TOOLCHAIN_TARGET_TASK</filename> variable.
</para>

<section id='adding-api-documentation-to-the-standard-sdk'>
<title>Adding API Documentation to the Standard SDK</title>
<para>
You can include API documentation as well as any other
documentation provided by recipes with the standard SDK by
adding "api-documentation" to the
<ulink url='&YOCTO_DOCS_REF_URL;#var-DISTRO_FEATURES'><filename>DISTRO_FEATURES</filename></ulink>
variable:
<literallayout class='monospaced'>
DISTRO_FEATURES_append = " api-documentation"
</literallayout>
Setting this variable as shown here causes the OpenEmbedded build
system to build the documentation and then include it in the standard
SDK.
