Warnings [Pg004] macro parameter "__VA_ARGS__"

[annapalu]

Hi all,

i have a little problem with the #define NRF_LOG. I have this warnings, and i don't know why.

Warning[Pg004]: macro parameter "VA_ARGS" is used in both expanded and raw forms

Someone have an idea about the reason?

Thank you, Anna

Hi all,

i understood that the problem is :

NRF_LOG(NRF_LOG_COLOR_RED "\n*** ASSERTION FAILED ***\n");

If i delete a NRF_LOG_COLOR_RED, not warning is generate, or if i use a NRF_LOG_PRINTF instead of NRF_LOG.

But i don't know why.

Chhers, Anna

I guess it might be a compiler issue. Something similar to this: Standard alternative to GCC's ##VA_ARGS trick.
