In case a package/image requres specific host dependencies it is possible to define entries in the `host_dependencies` array. Each entry is an object containing at least `name` and `which`. The `which` array contains tools to be checked in the current `PATH`. Optionally the two options `success_diffconfig` and `fallback_diffconfig` can be set. The former is optionally added in case the tool is found. The latter is added if the dependency is not available. If the dependecy is not available and no `fallback_diffconfig` is set, the config generation is considered impossible and stopped. Signed-off-by: Paul Spooren <mail@aparcar.org>

Subject: [PATCH] scripts: gen_config.py add host_dependencies option
|
|
|
|
In case a package/image requres specific host dependencies it is
|
|
possible to define entries in the `host_dependencies` array. Each entry
|
|
is an object containing at least `name` and `which`. The `which` array
|
|
contains tools to be checked in the current `PATH`.
|
|
|
|
Optionally the two options `success_diffconfig` and
|
|
`fallback_diffconfig` can be set. The former is optionally added in case
|
|
the tool is found. The latter is added if the dependency is not
|
|
available.
|
|
|
|
If the dependecy is not available and no `fallback_diffconfig` is set,
|
|
the config generation is considered impossible and stopped.
