Using gcc?

[version2]

I have some c code I'm trying to compile. I installed gcc, and the gmp lib, but I seem to be having some problems. I don't program in c myself, so I really don't know what any of this means.

chris@debian:~$ gcc pi.c -lm -lgmp -O3
pi.c:1:19: error: stdio.h: No such file or directory
pi.c:2:18: error: math.h: No such file or directory
pi.c:3:17: error: gmp.h: No such file or directory
pi.c: In function âmainâ:

do you have all the essential packages installed or they may not ben configured properly

if you aren't sure of having essential packages on your system do this

sudo apt-get install build-essential
