Error building watchdog (undefined reference to nrfx_wdt_init)

Question

Hello, I'm trying to add watchdog to my application based on SDK16.0 and NRF52811. In sdk_config.h I have added : #define WDT_ENABLED 1
#define NRFX_WDT_ENABLED 1 
 
 In my main.c : 
 #include "nrf_drv_wdt.h"

void watchdog_init(void)
{
 nrf_drv_clock_init();
 nrf_drv_wdt_config_t config = NRF_DRV_WDT_DEAFULT_CONFIG;
 uint32_t err_code = nrf_drv_wdt_init(&config, watchdog_handler);
 APP_ERROR_CHECK(err_code);
 err_code = nrf_drv_wdt_channel_alloc(&m_channel_id);
 APP_ERROR_CHECK(err_code);
 nrf_drv_wdt_enable();
}

int main(void) {
 (...)
 watchdog_init();
} 
 I'm getting error : 
 /usr/share/segger_embedded_studio_for_arm_4.50/gcc/arm-none-eabi/bin/ld: Output/soft_s112 Release/Obj/main.o: in function `nrf_drv_wdt_init':
<>/s112/ses/../../../../../../integration/nrfx/legacy/nrf_drv_wdt.h:102: undefined reference to `nrfx_wdt_init'
 
 What am I missing ? Thanks for your help ! Quentin

Hi Quentin, 
 Do you include the nrfx_wdt.c under nRF5_SDK\modules
rfx\drivers\src and add the path of nrfx_wdt.h under nRF5_SDK\modules
rfx\drivers\include into the makefile?
