Multiple definition error in app_uart_fifo

Hi

I combined ble_app_uart with relay example .I am getting a multiple definition error in app_uart_fifo while building.I have added required .c files and their header paths and also compared the sdk config file of uart example with relay example.Please let me know if I am missing something.Find below the attached screenshot.

Thank you

  • The message text says it all:

    A "multiple definition" means that you have the same thing defined in multiple places.

    The 'C' programming language requires that things must be defined once - and only once.

    The message also tells you where it is finding all the multiple  definitions - so you need to go through those definitions, and decide which is the one to keep.

    This is standard 'C' stuff - nothing specifically to do with Nordic or SES

    It would be easier to analyse & explain the messages if you copied them & pasted text

    Post as for source code, but omit step 3 (ie, leave as just 'Text):
