Why on earth would you pass 'tcp_active_pcbs'? Wherever you got that 
from: tell them this is wrong and they should stop spreading such 
horrible code examples!

Starting with 2.0.0, you can even link this only when including 
"lwip/priv/tcp_priv.h". And guess what, 'priv' means 'private'. Not 
'public'! You should smell there's something wrong when an application 
needs to include the private headers of the stack!

This indicates you have not called lwip_init(). I wonder who told you 
how to start with lwIP? Did you see there are actually files in the 
'doc' folder?

Really (and not meant in an offensive way!), I'm with Dirk thinking you 
need someone teaching you lessons on embedded programming. Or you need 
to pay someone programming your devices if this is about devices you 
want to sell...
