Including custom zephyr module

It does indeed try to build the module without needing the EXTRA_ZEPHYR_MODULES. Can it be possible that the build order is different when using it through the west manifest compared to the EXTRA_ZEPHYR_MODULES?

yes, the build order is different.
Zephyr modules provided with `EXTRA_ZEPHYR_MODULES` are processed after `ZEPHYR_MODULES`.
In general `ZEPHYR_MODULES` are obtained by `west list` but can also be provided as build argument.

Therefore, when `test-module` is in the manifest at the location you present, then I assume that it comes first in the list (second in case your manifest project is also a Zephyr module)

In general it is wise to have Zephyr modules self-contained, however this is not always possible, and in situations where a Zephyr module depends on other modules, then one should add `depends:` to the module.yml file.

For example the following will add a dependency between your module `and hal_nordic`:

name: test-module

build:
  depends:
  - hal_nordic
  cmake: .
  kconfig: ./library/Kconfig

Hi Dejan,

I just tried your suggestion and removing the EXTRA_ZEPHYR_MODULES does not seem to be the trick unfortunately. When I remove this line and add the submodule again in the west manifest, it fails with the same errors as in my original question.

Hi,

You should use either west manifest or EXTRA_ZEPHYR_MODULES variable. If you want that your module gets included in the west update, you could try to remove EXTRA_ZEPHYR_MODULES line from your CMakeLists.txt file.

Best regards,
