[lwip-users] Re: [lwip] Problems with 0.5.1 release

Hi Rajaram!

Looks like this is a case were your mileage does vary!
I just tried lwIP 0.5.1 on my Mandrake Linux running kernel
2.4.16 and it compiles and runs fine. The erros that you are
getting are because there is a problem with /usr/include/linux/if_tun.h
What version of Linux are you running?

If you are not running Linux 2.4.x you need to find the proper
include file that contains those definitions. Going back to 0.5.0
won't help because there were problems with the tap device.
