Having trouble compiling C code on ubuntu. (#include errors)

[Bond112]

I'm trying to compile a C program on ubuntu 12.10 running in vmware, for the purpose of putting the compiled program on another, older linux machine later. However, when I compile with gcc prog.c -o prog, I get an error: "fatal error: asm/page.h: No such file or directory" Here are the headers:

#include <stdio.h>
#include <errno.h>
#include <stdlib.h>
#include <string.h>
#include <malloc.h>
#include <limits.h>
#include <signal.h>
#include <unistd.h>
#include <sys/uio.h>
#include <sys/mman.h>
#include <asm/page.h>
#include <asm/unistd.h>

I get an error at #include. It says "fatal error: asm/page.h: No such file or directory." How can I get the missing header? Thanks.

have you tried to run the following command in a Terminal window:
sudo find / -iname page.h:?:
If that file exists on the HD on which you installed Ubuntu, with that command you'll find it.

Well I found files named that in a number of locations, but I don't understand how I should make the program access it. Here's the results:

I get the same error.

Yes that's me obviously. I still haven't been able to compile it though. You can see my reply to the last answer.

What about the first answer?

Pass -I/usr/src/linux-headers-3.5.0-17/arch/x86/include/ to your CFLAGS - including a file in <> denotes a system location, and the purpose of the CFLAGS parameters are to tell your compiler to look in additional directories as a system location.

However, I'd still consider the point of whether it's necessary to include that file at all, like was suggested on SO.
