Topic: -Wpacked-not-aligned warning

Hi Forum,

Using WolfSSL with mplabx XC32 compiler shows several warnings related to 

-Wpacked-not-aligned

Example:

In file included from ../src/config/default/definitions.h:63,
                 from ../src/main.c:28:
../src/config/default/library/tcpip/tcpip.h:272:1: warning: alignment 1 of 'struct _IPV6_ADDR_STRUCT' is less than 2 [-Wpacked-not-aligned]
 } IPV6_ADDR_STRUCT;

The program compiles but the warnings are numerous, very noisy and makes debugging a bit more difficult.
Is there a way to silence these specific warnings?

Thank you.

Hi rlev,

You should be able to silence these warnings using: 

-Wno-packed-not-aligned

I will look into getting these warnings fixed.

Thanks,
Kareem
