Error: L6200E: Symbol app_error_handler multiply defined (by app_error.o and main.o).

Hi All,

I am trying to interface an SPI OLED display 128x32 with my nrf51422 development kit over SDK 12.2.0 with BLE. After the program gets compiled, i am getting this error Error: L6200E: Symbol app_error_handler multiply defined (by app_error.o and main.o). Not enough information to list image symbols. Not enough information to list the image map. Finished: 2 information, 0 warning and 1 error messages.

and the project is not building.
What could be the reason?

Have you declared anything in main.c called app_error_handler? Could you upload your main.c file?

HI.. I got the same problem..

As suggested by RK in this thread, you should remove the implementation of app_error_handler from main.c. I suspect you are using this example, which is written for SDK 10. app_error have changed from SDK 10 to SDK 12.2. If you want the example to compile without changes, you need to use it with SDK 10.
