I made a stupid mistake and forgot to simply include the necessary header files which led to an implicit declaration without a function definition. therefore there were no object files for the functions and the linker called an error.

sigh. sorry to bother you haha.

So it might help to change the title of your question to something more specific like "how add link folder in Keil" so that someone who can help will see it. You don't seem like a newbie. Very respectfully yours, and good luck.

hey butch,

thanks again :) yes actually thats what im looking for at the moment, a way to add folders to the linker. at first sight i couldnt figure out where to change the linkers search folders because the option i found was immutable.

Sorry, not a Keil user. In Eclipse using managed make, it automatically compiles and links every file that is "in" the project. I would think Keil would do something similar. Or is there a makefile that you manually edit? If so, add the file.o to the linker command in the makefile.

Hey butch,

Find the file where it is defined, and add that file to the Makefile or project. To find it:

>cd ~/NRFSDKxx
>grep nrf_drv_clock_init *

From the list, pick out the file where it is defined. Probably .../components/nrf_drv/nrf_clock.c (just a guess).
