undefined reference to `nrf_pwr_mgmt_init

[All4here]

hello,

       i am using the Nrf52840 , SDK version 15 with segger embedded studio.

i am developing simple application but i got this issue. i already add the reference in the following location 

project-> edit option -> common-> Preprocessor-> user includes dic.

i already used some  custom library which is working fine but not power management  library.

.c file is also included. the error is coming from the linker 

here is the output

thank you

Did you add nrf_pwr_mgmt.c to your project? [Edit: never mind, I see it in your compilation log]

Did you redefine the NRF_PWR_MGMT macro in sdk_config.h?

[All4here]

yes  already add  nrf_pwr_mgmt.c   into the project 

NRF_PWR_MGMT_ENABLED is only defined one time which is equal to 1 means already enable.

Hi,

Did you solve this yet? If not, can you share your project files?

[All4here]

still i have issue.please check the attachment.

thank you Archive.zip

Are you using the SmartID.emProject Segger Embedded Studio project file? And does your project compile without the pwr_mgmt stuff? Your include directories points to ../../../config, but your sdk_config.h file rather seems to be located in ../config. If your project file can't see sdk_config.h, or if it sees the wrong sdk_config.h file, your defines won't matter. 

[All4here]

yes i am using the SmartID.emProject.

yes my project compile without pwr_mgmt.

i removed the ../../../config. and add the reference to the ../config.

but still same error with pwr_mgmt _stuff..

thank you

Hi, 

I just tried to import pwr_mgmt into a clean project, and it shouldn't be more to it than

1. adding nrf_pwr_mgmt.c to your project files,
2. including a path to the library folder,
3. including nrf_pwr_mgmt.h in your main.c,
4. enabling in sdk_config.h.

But is it seems like you have done all of that. I can't compile your files because you have used absolute file paths in your project which makes it hard to debug. 

Are you able to add any other libraries or drivers?

Are you able to add pwr_mgmt to a clean project, like the blinky example?

Hi Martin

As you see below, the problem is that Nordic forgot to add ifdef with extern "C" in nrf_pwr_mgmt.h. This directive is added in other libraries but not in this one. Plaease fix it in next SDK release. Thanks.
