[UdjinPr]

Hello,

I am trying to insert fds functionality to light switch client. I added all files and libraries to project. But when i try to compile project i face with errors :

Build failed

And i couldn't find these variables in both projects

Hi.

All these functions are defined in components\libraries\log\src\nrf_log_frontend.c, so you have probably not included that file, the header file, or both correctly.

Best regards,

Hi,

I double checked about these files. In my project there is a folder of header file in 'User include Directories' and there is nrf_log_frontend.c

[AndreasF]

Hi.

Which IDE are you using, Segger Embedded Studio? Keil?

Best regards,

Andreas

[UdjinPr]

SES

[AndreasF]

Hi.

And did you include the source file (.c file) like this?

And add the header file (.h file) like this?

Best regards,

Andreas

Yes, as i said before. 

And i can't figure out where variable __stop_log_backends is.
