The <filename>populate_sdk_*</filename> family of classes support
SDK creation.
This family of classes consists of the following:
<itemizedlist>
<listitem><para><emphasis><filename>populate_sdk_base</filename>:</emphasis>
The base class supporting SDK creation under all package
managers (i.e. DEB, RPM, and IPK).</para></listitem>
<listitem><para><emphasis><filename>populate_sdk_deb</filename>:</emphasis>
Supports creation of the SDK given the Debian package manager.
</para></listitem>
<listitem><para><emphasis><filename>populate_sdk_rpm</filename>:</emphasis>
Supports creation of the SDK given the RPM package manager.
</para></listitem>
<listitem><para><emphasis><filename>populate_sdk_ipk</filename>:</emphasis>
Supports creation of the SDK given the IPK package manager.
</para></listitem>
</itemizedlist>
</para>
<para>
The <filename>populate_sdk_base</filename> package inherits the
appropriate <filename>populate_sdk_*</filename> (i.e.
<filename>deb</filename>, <filename>rpm</filename>, and
<filename>ipk</filename>) based on
<link linkend='var-IMAGE_PKGTYPE'><filename>IMAGE_PKGTYPE</filename></link>.
</para>
<para>
The base class ensures all source and destination directories are
established and then populates the SDK.
After populating the SDK, the <filename>populate_sdk_base</filename>
class constructs two images:
<link linkend='var-SDK_ARCH'><filename>SDK_ARCH</filename></link><filename>-nativesdk</filename>,
which contains the cross-compiler and associated tooling, and the
target, which contains a target root filesystem that is configured for
the SDK usage.
These two images reside in
<link linkend='var-SDK_OUTPUT'><filename>SDK_OUTPUT</filename></link>,
which consists of the following:
<literallayout class='monospaced'>
${SDK_OUTPUT}/&lt;sdk_arch-nativesdk pkgs&gt;
${SDK_OUTPUT}/${SDKTARGETSYSROOT}/&lt;target pkgs&gt;
</literallayout>
</para>
<para>
Finally, the base populate SDK class creates the toolchain
environment setup script, the tarball of the SDK, and the installer.
</para>
<para>
The respective <filename>populate_sdk_deb</filename>,
<filename>populate_sdk_rpm</filename>, and
<filename>populate_sdk_ipk</filename> classes each support the
specific type of SDK.
These classes are inherited by and used with the
<filename>populate_sdk_base</filename> class.
