[lwip-users] undefined reference to sockets api

[rocco brandi]

hi everyone!

I'm trying to use the sockets api, but when I compiling I revice the following errors in the creation of the object file nicdrv.o (the nicdrv.c module is the one when the api are used):

.\Output\netX100\nicdrv.o: In function `ec_setupnic':
.\Sources\netX100\source/nicdrv.c:266: undefined reference to `lwip_socket'
.\Sources\netX100\source/nicdrv.c:266: undefined reference to `lwip_setsockopt'
.\Sources\netX100\source/nicdrv.c:266: undefined reference to `lwip_bind'
.\Sources\netX100\/nicdrv.c:266: undefined reference to `lwip_fcntl'
.\Output\netX100\nicdrv.o: In function `ec_closenic':
.\Sources\netX100\/nicdrv.c:277: undefined reference to `lwip_close'

Does anybody knows where is the problem?

Thanks ^_^
