undefined reference to `nrf_nvic_state' when i clearly included nvic.h

[julian24]

Hello everyone

I'm trying to build an app using Segger Embedded Studio and a nRF52832. I'm currently struggling to include the fds module since i get the following errors:

Building ‘basurometro_lte_52’ from solution ‘basurometro_lte_52’ in configuration ‘Release’
Linking basurometro_lte_52.elf
Output/Release/Obj/basurometro_lte_52/nrf_sdh.o: in function `softdevice_evt_irq_disable':
undefined reference to `nrf_nvic_state'
Output/Release/Obj/basurometro_lte_52/nrf_sdh.o: in function `softdevices_evt_irq_enable':
undefined reference to `nrf_nvic_state'
Build failed

Those references shouldn't bother the building process since I have nvic.h included and these softdevice directories included in my project( (among many other necessary ones):


C:/nRF5_SDK_17.1.0_ddde560/components/softdevice/common
C:/nRF5_SDK_17.1.0_ddde560/components/softdevice/s132/headers
C:/nRF5_SDK_17.1.0_ddde560/components/softdevice/s132/headers/nrf52

So i'm not really sure why this problem may have come up. Can anyone help me?

Hi,

In general, it is recommended to start with one of the Bluetooth projects if you want to create a project that includes SoftDevice. Otherwise, you will need to manually resolve and apply SoftDevice dependencies and configurations.

The global 'nrf_nvic_state' variable is defined in app_util_platform.c, so the linker error suggests that you have not included app_util_platform.c in your build.

Best regards,

Vidar

hello.

i tried using an sdk_config from ble projects, but it didn't work. Also, i have app_util_platform.c included in my build.

Then you are likely missing 'SOFTDEVICE_PRESENT' in your list of preproccessor symbols.
