Lots of warning in Nordic library

[Bar]

I use the SES ver 4.12 with embOS of Segger.

It happened to me all the time.

I take an example from Nordic. I rebuild it with no warning. Then I take and add my files , build a new app. On rebuild I have no error but a lot of worning comming only from the Nordic standard lib.

FOr example:

#if NRF_MODULE_ENABLED(XXXX)

*XXX mean different defines

with warning "this use of "defined" may not be portable [-Wexpansion-to-defined] "

It show on all libraries 

In app_timer.c this warning.

Like "no previous prototype for 'RTC1_IRQHandler' [-Wmissing-prototypes]" because there is no declare in the h. (How it can be use in different c files without declare in the h file?

and it get repeated again and again. 

I get about 3600 warning from those types.

1. Is it something I need to be worry about ?

2. Why it is show in Nordic library which show be clean from warnings?

3. If it is not critical and usual, can I  change any setting not to see them?

Regards

Bar.

Hello Bar,

Did you include the file ses_startup_nrf52840.s file in your project? This file is included in the examples in the SDK, and is probably the reason why you don't get the same warnings there.

That being said, I am not too familiar with embOS.
