[lwip-devel] [patch #9072] Add missing include for lwip/sys.h

[Sylvain Rochet]

Follow-up Comment #5, patch #9072 (project lwip):

Hi Axel,

Well, that's not how it is supposed to work, if your random function actually
live in your sys_arch.c, that's your problem, but this is not how it was
designed.

The current design behind it is to have your random implementation somewhere,
in let's say, random.c/random.h, and then cc.h should looks like this:

#include "random.h"
#define LWIP_RAND() my_random() 

Although I agree having it in sys_arch.c is perfectly fine and I would do the
same if I needed a function around my random call :)

Sylvain
