With everyone's help I finally got my first linux installation working. I hadn't programmed in c in two years, so anxious to get started. I typed in my starter program in pico.

#include<stdio.h>

void main()
{
printf("hello");
}

I then compiled hello.c:

gcc hello.c

It spewed back an error message, something about main not being int.

What am I doing wrong? Thanks for your help!
