[lwip-users] compiling LWIP 1.3.2 on IAR EWARM 6.0

[Carol Lai]

Hi,

 

I’m compiling LWIP 1.3.2 as C++ language in IAR.  But I’m getting the following error message.

 

 

Error[Pe135]: class "tcp_pcb" has no member "lwip_recv" C:\Projects\Plastic\LWIP_Problem\platform\StellarisWare\third_party\lwip-1.3.2\src\core\tcp.c 837

Error while running C/C++ Compiler

 

 

It appears that IAR is not replacing the macro correctly.  Does anyone know how to set them up correctly for IAR compiler?

Thanks,

 

Carol

There a at least three things that are strange here:
1. IAR doesn't seem to care that the recv() macro (defined at the end of sockets.h) is a function-like macro but 'recv' is not used as a function in tcp.c. That might be a problem of compiling it as C++ (and not C).
2. It seems like somehow tcp.c includes sockets.h (which it shouldn't) - or where does the redefinition from 'recv' to 'lwip_recv' come from? Did you place an include to sockets.h somewhere in a global header file (e.g. lwipopts.h or cc.h)?
3. tcp.c 837 of lwIP 1.3.2 says "pcb->flags &= ~(TF_ACK_DELAY | TF_ACK_NOW);" - I don't see where recv or lwip_recv is referenced??

If you don't find why sockets.h is included from these files, I'd recommend to disable LWIP_COMPAT_SOCKETS first, that should correct it, but you then have to define it to 1 in every application file before including sockets.h (if you really need that feature).

Also, you might want to upgrade to 1.4.0, since 1.3.2 is outdated.

LOL, that's a funny footer for a message sent to a public list which is archived in many places on the web :-)
