STATIC_ASSERT and GCC (instead of Keil)

[Jim]

I'm bringing up ble_app_hrs as an eclipse project using gcc.

I'm running into an error in app_util.h, line 67:

#define STATIC_ASSERT(EXPR) typedef char static_assert_failed[(EXPR) ? 1 : -1]

The error is:

typedef 'static_assert_failed' locally defined but not used [-Werror=unused-local-typedefs] ble_app_hrs line 67, external location: ..../nrf51822/Include/app_common/app_util.h C/C++ Problem

I believe the instance of STATIC_ASSERT it's complaining about is in app_timer.c, line 1035:

STATIC_ASSERT(APP_TIMER_INT_LEVELS == 3);

QUESTION: what's up with this? Is there some kind of support I need to add so this mechanism will work correctly?

As far as I can see, this is a consequence of using GCC 4.8q4, in combination with -Werror, which turns all warnings into errors. Earlier versions of GCC have not given a warning on this construct, but it seems 4.8 does.

The application note is written for a previous version of GCC, but there shouldn't be any problems by using later versions if you just solve this one. That can either be done by removing the -Werror flag from line 60 of Makefile.common, or fix app_util.h as follows:

#define STATIC_ASSERT(EXPR) typedef char static_assert_failed[(EXPR) ? 1 : -1] __attribute__((unused))

Thanks! That did the trick. I'm now ale to build 5.1.0 with gcc.

worked here as well

Beautiful!

Hello to every one,

i must compile some .c and .h file in a project, am using MPLAB-X-IDE 6.20 and avr gcc 7.3.0 (for program my ATMega644P mcu).

the error up it seems like my errors, please can you rewrite for me this lines? thank you.

Compiler is unable to compile follow lines:

_Static_assert(__builtin_offsetof(struct SysTick_Regs, CALIB) == 0x1c - 0x10, "struct SysTick_Regs has incorrect size");

give me error: lpc17xx/lpc176x.h:62:42: error: "(" may not appear in macro parameter list
