troubles with linking

[Mohamed O.Abouzeid]

while I'm trying to compile my code, I got an error :

".\Objects\ble_firmware_v1.axf: Error: L6405E: No .ANY selector matches main.o(i.app_error_handler). "

this error appeared at linking process

I don't know how to solve this error & why it appear ?

Did you include components\libraries\util\app_error.c in your project? This file is needed if you have not implemented your own app_error_handler
