[lwip-users] [lwip] lwip

[Zhang Liandong]

i have port lwip to ucos and now i can browse web page get from the target 
system which run ucos+lwip, but after i refresh the browser several times pbuf 
is used up then lwip stop work. Through debug by printf i find the number of 
pbuf is reduced by a constant value(for a big web page it is 4 for a very 
little one it is 1). but no pbuf is stay on any pcbs, that means some pbufs is 
simply dropped after being used not being freed back to lwip. 

help,help,help

No, simhost and others are just example programs. lwIP is compiled as a
library and these programs are linked against it.

Run simhost by typing './simhost'. Maybe you need privileges to access the
tap device, so maybe you need to run it as root. After that you have a web
server running on the IP address 192.168.0.2. Try to put this number in a
web browser or "ping 192.168.0.2". That's lwIP working.

BTW, isnt it in the documentation?
