Are there "NCS_VERSION" or "NRF_VERSION" C makros available?

[Achim Kraus]

Today I recognized that in one of the  updates since ncs 1.8.0, now "nrf_modem_gnss_fix_interval_set" returns -NRF_EINVAL, if GNSS is already running. In older versions it was -NRF_EPERM.

If an application is considered to work with different ncs/nrf versions, is it possible to detect that ncs/nrf version via C preprocessor makros?

Such breaking API changes are unfortunately the cause of quite a lot of issues. Is there a list of such return value changes? If not, I would welcome such a list very much.

This can be done using Cmake and https://github.com/nrfconnect/sdk-nrf/blob/v2.3.0/VERSION.

Tested it using the Zephyr Hello World sample:

# SPDX-License-Identifier: Apache-2.0

cmake_minimum_required(VERSION 3.20.0)


find_package(Zephyr REQUIRED HINTS $ENV{ZEPHYR_BASE})
project(hello_world)

file(STRINGS ${ZEPHYR_BASE}/../nrf/VERSION NCS_VERSION_CMAKE)
add_definitions( -DNCS_VERSION="${NCS_VERSION_CMAKE}")

target_sources(app PRIVATE src/main.c)

Thanks!

In the meantime I also found a "ncs_version.h", which is generated during the build process.
