DBG_OFF and more are in debug.h.  Lwipopts.h should #include lwip/debug.h

 

It would be really helpful if we can use a better message subject and keep it constant – there is no thread history in the archives for this problem – I wanted to see this thread from the beginning to see if I missed anything.

The reason stat_display is not working is because DBG_OFF (maybe more) @lwipopts.h is not defined anywhere in lwip's files. Which is not a problem until I added #define LWIP_DEBUG to debug.h

Unfortunately, AVR32 Studio's compiler didn't realize I changed debug.h so it didn't bother to recompile it until I cleaned and rebuild all files.

How should I debfine DBG_OFF, DBG_ON, etc?

That isn't quite what I meant.  To send data do you call tcp_write()

or 

netconn_write() or send() for example?  If you use tcp_write()

directly then 

MEMP_NUM_NETBUF will have no effect and is not your problem.

If you call the function to display that stats and it shows nothing then 

something is wrong: it should print statistics about the resources

used.  

You'll have to debug what's gone wrong.
