Hi all,
I have a problem compiling programs that include sys/socket.h.
I use a very simple program as an example:
/*incl.c*/
#include <sys/socket.h>
#include <stdio.h>
int main(int argc, char *argv[])
{
printf("ciao\n");
return 0;
}
As you can see it doesn't call any function about sockets. It only
includes sys/socket.h.
When I run gcc incl.c I have the following answer:
In file included from incl.c:1:

Then, if I put #include<stdio.h> before the inclusion of sys/socket.h
it works without any error!
/*incl.c*/
#include <stdio.h>
#include <sys/socket.h>
int main(int argc, char *argv[])
{
printf("ciao\n");
return 0;
}
Can you help me?
Did I make any mistake?
Thank you in advance
NIK
