nrf9160 preprocessor options

[PeterC]

Hi,

I have a similar problem to the case: (devzone.nordicsemi.com/.../having-a-problem-with-preprocessor-options) with not being able to access the preprocessor options. I have made a copy of the mqtt-simple sample and loaded it through "Open nRF Connect SDK project". I am now adding some GPIO code. I have added CONFIG_GPIO=y to the prj config file and I am now getting the error  "gpio.h: No such file or directory". After research: (https://devzone.nordicsemi.com/f/nordic-q-a/31245/segger-embedded-studio---unable-to-add-user-include-directories-no-such-file-or-directory)  I need to include the directory within the preprocessor options tab but the only options available to me are shown below. Loading the example mqtt_simple project also does not give me the preprocessor tab.

Any ideas on what I am missing?

Thank you

Hi,

 

Changes in zephyr were introduced, which changed the include paths for drivers and other components (https://github.com/NordicPlayground/fw-nrfconnect-nrf/pull/1811).

 

Could you try including #include<drivers/gpio.h> and see if this resolves the issue?

 

Kind regards,

Håkon

Thanks Hakon, that fixed the issue.

Is this link a complete list of all the paths that have changed? (https://github.com/NordicPlayground/fw-nrfconnect-nrf/pull/1811/files)

Does this also mean I will not need to access the preprocessor tab to include paths from now on? I hope so since I cannot access it...any thoughts on why it is not available? 

Cheers

Hi Peter,

That is correct! Its a change from "component.h" to "<subsystem>/component.h", but it doesn't only apply to drivers. It applies to most systems in the OS itself, like printk is now:

#include <sys/printk.h>

Old:

#include <misc/printk.h>

 Yes, there is here:

https://github.com/zephyrproject-rtos/zephyr/issues/16539

 

If you get stuck on a certain header or similar, just let me know and I'll try to help out.

 

Cheers,

Håkon
