nrfx_gpiote_init undefined reference

Question

Hi, 
 I have shifted from Arduino to nrf. Arduino is straight forward and with very less dev time. I understand this is way more powerful and next level platform, but does it have to be so painful to work on this platform? 
 
 From the past four hours, I have been struggling with the implementation of the interrupt. I am looking at the code in the example "pin_change_int". Everything makes sense and when i copy the logic to my own program I get following GPIOTE errors. 
 
 I have tried copying sdk_config.h GPIOTE text and enabling it from CMSIS editor. 
 I have tried importing nrf_gpiote.c file from modules
rfx\drivers\src 
 I watched the video that shows how to import driver. GPIOTE driver does not exist in the given folder 
 nrf_drv_gpiote. exists in the legacy folder. If it's legacy what is new? 
 
 errors are 
 undefined reference to `nrfx_gpiote_init' 
 undefined reference to `nrfx_gpiote_in_init' 
 undefined reference to `nrfx_gpiote_in_event_enable'

For people out there they need to do the following. 1. Include file from nRF5_SDK\modules rfx\drivers\src rfx_gpiote.c 2. Copy `sdk_config.h` text //========================================================== // GPIOTE_ENABLED - nrf_drv_gpiote - GPIOTE peripheral driver - legacy layer //========================================================== #ifndef GPIOTE_ENABLED #define GPIOTE_ENABLED 1 #endif // GPIOTE_CONFIG_NUM_OF_LOW_POWER_EVENTS - Number of lower power input pins #ifndef GPIOTE_CONFIG_NUM_OF_LOW_POWER_EVENTS #define GPIOTE_CONFIG_NUM_OF_LOW_POWER_EVENTS 1 #endif // GPIOTE_CONFIG_IRQ_PRIORITY - Interrupt priority // Priorities 0,2 (nRF51) and 0,1,4,5 (nRF52) are reserved for SoftDevice // <0=> 0 (highest) // <1=> 1 // <2=> 2 // <3=> 3 // <4=> 4 // <5=> 5 // <6=> 6 // <7=> 7 #ifndef GPIOTE_CONFIG_IRQ_PRIORITY #define GPIOTE_CONFIG_IRQ_PRIORITY 6 #endif // // NRFX_GPIOTE_ENABLED - nrfx_gpiote - GPIOTE peripheral driver //========================================================== #ifndef NRFX_GPIOTE_ENABLED #define NRFX_GPIOTE_ENABLED 1 #endif // NRFX_GPIOTE_CONFIG_NUM_OF_LOW_POWER_EVENTS - Number of lower power input pins #ifndef NRFX_GPIOTE_CONFIG_NUM_OF_LOW_POWER_EVENTS #define NRFX_GPIOTE_CONFIG_NUM_OF_LOW_POWER_EVENTS 1 #endif // NRFX_GPIOTE_CONFIG_IRQ_PRIORITY - Interrupt priority // <0=> 0 (highest) // <1=> 1 // <2=> 2 // <3=> 3 // <4=> 4 // <5=> 5 // <6=> 6 // <7=> 7 #ifndef NRFX_GPIOTE_CONFIG_IRQ_PRIORITY #define NRFX_GPIOTE_CONFIG_IRQ_PRIORITY 6 #endif // NRFX_GPIOTE_CONFIG_LOG_ENABLED - Enables logging in the module. //========================================================== #ifndef NRFX_GPIOTE_CONFIG_LOG_ENABLED #define NRFX_GPIOTE_CONFIG_LOG_ENABLED 0 #endif // NRFX_GPIOTE_CONFIG_LOG_LEVEL - Default Severity level // <0=> Off // <1=> Error // <2=> Warning // <3=> Info // <4=> Debug #ifndef NRFX_GPIOTE_CONFIG_LOG_LEVEL #define NRFX_GPIOTE_CONFIG_LOG_LEVEL 3 #endif // NRFX_GPIOTE_CONFIG_INFO_COLOR - ANSI escape code prefix. // <0=> Default // <1=> Black // <2=> Red // <3=> Green // <4=> Yellow // <5=> Blue // <6=> Magenta // <7=> Cyan // <8=> White #ifndef NRFX_GPIOTE_CONFIG_INFO_COLOR #define NRFX_GPIOTE_CONFIG_INFO_COLOR 0 #endif // NRFX_GPIOTE_CONFIG_DEBUG_COLOR - ANSI escape code prefix. // <0=> Default // <1=> Black // <2=> Red // <3=> Green // <4=> Yellow // <5=> Blue // <6=> Magenta // <7=> Cyan // <8=> White #ifndef NRFX_GPIOTE_CONFIG_DEBUG_COLOR #define NRFX_GPIOTE_CONFIG_DEBUG_COLOR 0 #endif // // REMOVE ME OR ELSE CMSIS WILL NOT WORK // 3. Remove one // from bottom of text out of 2 otherwise CMISS wont work 4. Go armgcc folder and open makefile. in SRC files add $(SDK_ROOT)/modules/nrfx/drivers/src/nrfx_gpiote.c \ Too much to do for a simple task.
