[lwip-users] [lwip] running error of simhost?

[杨晔]

    I compiled lwip 0.5.3 under mandrake linux. Just "make" in the unixsim dir 
and then I got "simhost","simnode","simrouter" program. But when I typed 
"./simhost" I got the message:
   System initialized
   TCP/IP initialized
   tapif_init : no such file or directory
then the program quit. and the other program do not run correctly either. 
    I just did as the README file says, what's wrong? ( I saw the tap_if.o 
after make)
