-description: |
- An example of creating a cross-compile SDK for an embedded Baserock system.
-
- This cluster demonstrates how you can use the 'sdk' write extension to
- produce a cross-compile SDK tarball for an Baserock applicance. In this
- example the system is assumed to run on ARMv7, and the SDK is built to
- run on any x86_32 GNU/Linux system.
-
- The SDK is a Baserock system itself, containing just 'build-essential' and a
- 'cross-toolchain' stratum. The SDK system also includes the target
- appliance's system, as a 'subsystem', so that the libraries and headers are
- available when building.
-
- This cluster deploys the SDK system using the 'sdk' write extension, which
- produces a tarball with a small shell header. When the shell header is
- executed, and passed a directory name on the commandline, it extracts the SDK
- to that path and patches the binaries so that they execute correctly from
- that directory.
-
- Deploying the applicate system artifact to the target device should be
- done with a separate cluster morphology, because you will often want to
- do this without rebuilding the SDK.
-
- You must build each system with `morph build` before deploying. We recommend
- doing this all from your Baserock development machine, using a Baserock
- ARM distributed build network to produce the system artifact. Once both
- system artifacts are cached locally, the `morph deploy` command will produce
- a self-extracting shell script/tarball following the 'location' field.
-
- See the documentation of the sdk.write extension for more information.
