I am using the example TWI_sensor_pca10040 with a main.cpp, and I see that there is some sort of error with the logging that I cannot point out. I get this error
Linking twi_sensor_pca10040.elf Output/twi_sensor_pca10040 nrf52832_xxaa/Obj/main.o: In function
main': undefined reference to
nrf_log_init(unsigned int (*)())'
The line causing the error is APP_ERROR_CHECK(NRF_LOG_INIT(NULL));
when calling NRF_LOG_INIT()
THe logging is not enabled
#define TWI_CONFIG_LOG_ENABLED 0
#define NRF_LOG_DEFAULT_LEVEL 0
If I enable it I get errors

If I disable the logging then everything goes fine since there is not logging, #define NRF_LOG_ENABLED 0
so, I wonder , what's happening?
thanks
