how to add the "hal_time_get()" API's library?

[CJChang]

Hi, 

I would like to use hal_time_get()  [hal_timer.h] in my project, and I try to add below library into Makefile.

but I got an error.  "error: implicit declaration of function 'hal_time_get'"

how can I call the "hal_time_get()" API on my project?

Thank you.

This error is about compilation, not linkage (that's were you need the library). Sounds obvious, but did you include the header file in the source you want to compile?

Hi RayCreemers,

Thank you.

Yes, I have included relate folder in the Makefile ($(SDK_ROOT)/components/802_15_4/api/HAL)

[RoyCreemers]

That is about the location of the include... Did you add

'#include "hal_timer.h"' in your source file?

If no... you should

If yes, then ther is probably another header file using the same include guard (HAL_TIMER_H_INCLUDED)

Hi Ray,

Thank you.

I have included "hal_timer.h" but still compile error.

  sc_printf("get time: %llu", hal_time_get());

and I grep my source code, the "HAL_TIMER_H_INCLUDED" only used in hal_timer.h

Hi.

implicit declaration of function 'hal_time_get' means that you are using the function hal_timer_get before the compiler has seen the declaration ("prototype").

Check that you don't call it before you declare it.

Best regards,

Andreas
