Re: [lwip-users] upgrade from 1.4.1 to 2.0.3

[Mattia Settin]

In addition I don't really get why

with NO_SYS = 0 (with FreeRTOS) sys_timeouts_mbox_fetch call sys_check_timeouts() which is the handle timeouts for NO_SYS==1 (without OS)

Probably I have an too old port file for FreeRTOS.

Yes, but sys_now is required even for timeouts for NO_SYS==0 (LWIP_TIMERS = 1). It this correct ?

The question is:
It is now mandatory define/use sys_now() ?

You can do without, but a number of features new to 2.0.x (or improved there) require it. Right now, the list is:
- timeouts for NO_SYS==1
- LWIP_SO_SNDTIMEO
- LWIP_SO_LINGER
- lwiperf app
- LWIP_TCP_TIMESTAMPS
- PPPoS

This list can grow longer in the future. As such, we can't ifdef out the prototype for these configs and it's always there. You can try without and you'll get a linker error once you enable code which actually uses it.
