Mesh SDK v2.2.0: Light Switch Build Fails on nrf_log.h & nrf_log_internal.h

[awneil]

Trying to build the unmodified light_switch_client_nrf52832_xxAA_s132_6_0_0.emProject from a fresh download of the Mesh SDK.

SDK_ROOT set & successfully tested as instructed.

app_error.c compile fails because it can't find nrf_log.h

so I added $(SDK_ROOT:../../../../nRF5_SDK_15.0.0_a53641a)/components/libraries/experimental_log to the Include Path

app_error.c compile then fails because it can't find nrf_log_internal.h

so I added $(SDK_ROOT:../../../../nRF5_SDK_15.0.0_a53641a)/components/libraries/experimental_log/src to the Include Path

Then it all builds OK.

So why was this missing from the Project??

Using Segger Embedded Studio.

Hi Andrew.

I'm unsure why this was missing from the project. I will create a ticket for the SDK team, so they are aware of it and can fix it.

Thanks for noticing this!

Hi again.

I've been trying to reproduce this issue, but I haven’t been successful in doing so.

Are both Mesh SDK 2.2.0 and SDK 15.0 vanilla (completely unmodified)?

Because when I use the two vanilla SDK's I can't reproduce the issue.

There could be that some files in your SDK 15.0, if you have modified them, that causes this issue.

I will continue to investigate the issue, and see if I find out anything else.

Ah, yes - the SDK installation has some changes. But the Mesh is "vanilla"

The problem was the locations of the nrf_log.h and nrf_log_internal.h files

They appear only in the components/libraries/experimental_log and components/libraries/experimental_log/src folders of my SDK.

Those paths were not in the Mesh Projects.

Pretty sure I haven't moved them, so do they also appear elsewhere in the "vanilla" SDK ?

EDIT

I should add that I was building the 'Debug' configuration.

The same applies to the Server & Provisioner projects.

Hi again.

They only appear in those two folders in the vanilla SDK as well.

I've tried all building configurations for the client, server, and provisioner project without receiving the error.

But there are many other files that the Mesh SDK uses from SDK 15. So maybe one of the other files from SDK 15 have been modified to include logging?

Could you try with a vanilla SDK 15 and see if you still get the error?

Ah - I guess that's possible. I'll have to try a fresh SDK.

But this would mean that none of the Mesh stuff uses logging?

Hi again.

It appears that Mesh has its own logging (found in nrf5_SDK_for_Mesh_v2.2.0_src_2\mesh\core\src\log.c).
