Evaluating compound expression within ASSERT()

[eyalasko]

Hi, 

My app was written on Windows PC/MSVC and is ported to nRF52/Keil.

In many places I've used MSVC assert() macro in the following manners:

• assert(function(arg1, arg2) == SUCCESS)
• assert(ptr)
• assert(ptr && intvar)

etc...

When porting it to nRF 52 I've tried to replace assert() with a generic MY_ASSERT() macro:

#if WINDOWS_PC

#define MY_ASSERT(cond)    assert((cond))

#else // nRF52+Keil

#define MY_ASSERT(cond)     ASSERT((cond))

#endif

Unfortunately when wrapping a function call+comparison MY_ASSERT(function(a,b) == SUCCESS), the source line is optimized out...

I tried to use ERROR_CHECK and also to implement do{int local_var = (cond); ASSERT(localVar);} while(0) type of tricks but it just doesn't work/compile

Any thoughts?

Thanks

Hi,

What SDK version are you using?

I have not checked how far back this holds, but at least in SDK 15 for the ASSERT macro to have any effect you must add the DEBUG_NRF preprocessor define. See nrf_assert.h. Without DEBUG_NRF or DEBUG_NRF_USER defined it will be an "if (false)".

Hi, 

I'm using SDK 14.2

Will give it a try.

Thanks
