===== Building The SDK =====

<note important>In order to build the SDK it is necessary to follow the relevant Quickstart Guide ([[resources:tools-software:linuxdsp:docs:quickstartguide:quickstart_sc589|SC589-EZKIT and SC589-MINI]], [[resources:tools-software:linuxdsp:docs:quickstartguide:quickstart_sc594|SC594-EZKIT]], [[resources:tools-software:linuxdsp:docs:quickstartguide:quickstart_sc598|SC598-EZKIT]]) for Setting Up Your Host PC.</note>

==== Preparing the buildtool ====
Yocto requires the environment to be configured before building is possible.  A setup-environment script in the griffin, gxp or gxp2 folder contains all the required environment settings.

<code>
$ source setup-environment -m adsp-sc589-ezkit
</code>
or
<code>
$ source setup-environment -m adsp-sc589-mini
</code>
or
<code>
$ source setup-environment -m adsp-sc594-som-ezkit
</code>
or
<code>
$ source setup-environment -m adsp-sc598-som-ezkit
</code>
Sourcing the script will configure your build environment and create a build folder along with a local build configuration file.  See the Yocto Manual for further details.

<note important>Note that the build environment needs to be sourced once only before building.  If later working in a different terminal the setup-environment script should be sourced again.  If sourcing the setup-environment script is done without specifying the machine Yocto will reuse the previous configuration settings and retain any changes made to the files in the conf folder.</note>

==== Building the SDK ====
The SDK can be built for the adsp-sc5xx-minimal image or the adsp-sc5xx-full image. To build the SDK for the adsp-sc5xx-minimal image invoke bitbake from within the build directory created previously.

<code>
$ bitbake adsp-sc5xx-minimal -c populate_sdk
</code>
or for the adsp-sc5xx-full image
<code>
$ bitbake adsp-sc5xx-full -c populate_sdk
</code>

When the build has completed you will find a set of files in the <BUILD_DIR>/tmp/deploy/sdk directory. For the minimal image on SC594:
<code>
$ ls tmp/deploy/sdk
poky-glibc-x86_64-adsp-sc5xx-minimal-armv7at2hf-neon-adsp-sc594-som-ezkit-toolchain-3.1.8.host.manifest
poky-glibc-x86_64-adsp-sc5xx-minimal-armv7at2hf-neon-adsp-sc594-som-ezkit-toolchain-3.1.8.sh
poky-glibc-x86_64-adsp-sc5xx-minimal-armv7at2hf-neon-adsp-sc594-som-ezkit-toolchain-3.1.8.target.manifest
poky-glibc-x86_64-adsp-sc5xx-minimal-armv7at2hf-neon-adsp-sc594-som-ezkit-toolchain-3.1.8.testdata.json
</code>
or the full image on SC598:
<code>
$ ls tmp/deploy/sdk
poky-glibc-x86_64-adsp-sc5xx-full-aarch64-adsp-sc598-som-ezkit-toolchain-3.1.8.host.manifest
poky-glibc-x86_64-adsp-sc5xx-full-aarch64-adsp-sc598-som-ezkit-toolchain-3.1.8.sh
poky-glibc-x86_64-adsp-sc5xx-full-aarch64-adsp-sc598-som-ezkit-toolchain-3.1.8.target.manifest
poky-glibc-x86_64-adsp-sc5xx-full-aarch64-adsp-sc598-som-ezkit-toolchain-3.1.8.testdata.json
</code>


The poky-glibc-x86_64-adsp-sc5xx-minimal-armv7at2hf-neon-adsp-sc594-som-ezkit-toolchain-3.1.8.sh and the poky-glibc-x86_64-adsp-sc5xx-full-aarch64-adsp-sc598-som-ezkit-toolchain-3.1.8.sh are self-extracting archives containing the SDK.

\\
==== Installing the SDK ====
Invoke the self-extracting archive.
It will default to installing to /opt/poky/3.1.8 but gives you the option to select your own install folder during the installation.
For the minimal image on SC594
<code>
$ ./poky-glibc-x86_64-adsp-sc5xx-minimal-armv7at2hf-neon-adsp-sc594-som-ezkit-toolchain-3.1.8.sh
Poky (Yocto Project Reference Distro) SDK installer version 3.1.8
=================================================================
Enter target directory for SDK (default: /opt/poky/3.1.8): 
You are about to install the SDK to "/opt/poky/3.1.8". Proceed [Y/n]? y
Extracting SDK...................................................................done
Setting it up...done
SDK has been successfully set up and is ready to be used.
Each time you wish to use the SDK in a new shell session, you need to source the environment setup script e.g.
$ . /opt/poky/3.1.8/environment-setup-armv7at2hf-neon-poky-linux-gnueabi
</code>
or for the full image on SC598 
<code>
./tmp/deploy/sdk/poky-glibc-x86_64-adsp-sc5xx-full-aarch64-adsp-sc598-som-ezkit-toolchain-3.1.8.sh
Poky (Yocto Project Reference Distro) SDK installer version 3.1.8

You are about to install the SDK to "/opt/poky/3.1.8". Proceed [Y/n]? y
Extracting SDK................................................................................................................................................................................................................done

</code>

Your SDK is now installed.
