I am using errno (global variable) in my socket.c file of the kernel
and have also include <bits/errno.h> file and also define Extern int errno in the socket.c file. I have done this to check out the errors which are received when a client and server are running ....
To include the changes which i have made in the socket.c file i am compiling the kernel. But it is giving me error as
Undefined reference to errno
So, anyone please help me out..
