lwip IAR Build

[alb]

I am running into a build problem using the IAR IDE. The problem seems to be with the inability to differentiate between:

C:\ChibiOS_2.6.4\ext\lwip\src\include\ipv4\lwip\icmp.h
C:\ChibiOS_2.6.4\ext\lwip\src\include\ipv6\lwip\icmp.h

The ipv4.c and and ipv6.c both include:

#include "lwip/icmp.h"

... I think the preprocessor is grabbing C:\ChibiOS_2.6.4\ext\lwip\src\include\ipv4\lwip\icmp.h for both cases.

I am ending up with errors such as:

Error[Pe020]: identifier "ICMP6_ECHO" is undefined C:\ChibiOS_2.6.4\ext\lwip\src\core\ipv6\icmp6.c 61
Error[Pe393]: pointer to incomplete class type is not allowed C:\ChibiOS_2.6.4\ext\lwip\src\core\ipv6\inet6.c 90
Error[Pe055]: too many arguments in invocation of macro "ip_init" C:\ChibiOS_2.6.4\ext\lwip\src\core\ipv6\ip6.c 63


How can I get around this problem?

Not sure, may be only one of those directories must be specified in the search path.

Okay, I took the ipv6 stuff out of the project and now am stuck with the following errors, for example:

These are condtionally defined in sys.h when NO_SYS is true in lwipopts.h - NO_SYS is zero as downloaded. If I change NO_SYS to a one, I get a boat load of other errors in api_lib.c, api_msg.c, lwipthread.c, sockets.c. But maybe that is progress.

You have to include the system module.

I suggest you give a look under ./os/various/lwip_bindings especially the .mk file.
