Include logging in hello_world

[Asbjorn Bjorkkjar]

Hi,

I have trouble with including the logging module in the easiest hello_world sample version for nRF5340 Audio. 

#include <zephyr/kernel.h>
#include <dk_buttons_and_leds.h>
#include <logging/log.h>

The zephyr and leds&buttons work, and I can find them in my version of SDK at: v2.2.0 -> nrf -> include. 

The <logging/log.h> and <logging/logging.h> however cannot be found. How can this be done?

Regards,

Asbjørn

I found the include-files for logging in: zephyr -> include -> zephyr -> logging. When I included the whole path to my project, it found the file.
I still wonder how I can use the "< >" notation, so I don't need to include my whole path every time.

Hi Asbjørn,

You need to add zephyr before logging:

#include <zephyr/logging/log.h>

Previously you did not need the 'zephyr' prefix, but this is necessary after the Zephyr public headers were moved to include/zephyr in v3.1.0 of Zephyr. You can read about this in the release notes: Release notes Zephyr 3.1.0. It is the first point under API changes: 

Best regards,

Thank you - it worked out! I haven't noticed the new version of zephyr.
