Incompatible redefinition of macro "STATIC_ASSERT_SIMPLE" and "STATIC_ASSERT_MSG"

[trevortjes]

Hey,

I am getting a

warning:  #47-D: incompatible redefinition of macro "STATIC_ASSERT_SIMPLE"  (declared at line 215)
warning:  #47-D: incompatible redefinition of macro "STATIC_ASSERT_MSG"  (declared at line 216)

#ifdef __CC_ARM
	#define STATIC_ASSERT_SIMPLE(EXPR)      extern char (*_do_assert(void)) [sizeof(char[1 - 2*!(EXPR)])]
	#define STATIC_ASSERT_MSG(EXPR, MSG)    extern char (*_do_assert(void)) [sizeof(char[1 - 2*!(EXPR)])]
#endif

in file app_util.h coming from the following files:

nrf_drv_twi.c

nrfx_saadc.c

app_timer.c

app_error_weak.c

nrfx_twi.c

nrfx_timer.c

nrfx_twim.c

And some other files I created myself.

I wonder what the right way is of dealing with this warning. Using a #ifndef does not work and spawns errors.

Could you tell me what to do in order to recreate this error? Maybe you could share your project?

Check out this link, that may help you.

Best regards,
