Check what has been assigned to varialbe NETINCLUDE and what is the actual path of the header files included in .c file? Are they same?

Now here it seems that compiler is not able to find the header files used in nat.c. So specify the search path of those header files in makefile , using -I option.

You can use do while loop. for eg:
char ch;

printf("Do u want to continue(y/n):");
scanf("%c",&ch);

hi..
First check whether you have declared structs more than 1 time or not.
To check open a terminal and go to the directory containing the source code, using cd command and than execute command ...

Understood d concept...
I will definately take care of d tag next time...
