Chris:
I'm no expert, but I'll take a swag.
This is happening because the compiler doesn't know where to look for
stdio.h, probably because it was installed in a "non-standard"
location. For example, if it was installed to /usr/local/include/
instead of /usr/include/ (or wherever the compiler expects it), the
compiler can't find it.
Long story short, you probably need to locate stdio.h and direct the
compiler to find it using -I (That's the dash 'eye' option). So if
stdio.h is in /usr/local/include/ I would compile with: gcc -I/
usr/local/include/ hello.c.
You can also find information on the internet about how to add a non-
standard directory to the compiler's search path so you don't have to
do this every time, but I'm lame on that and just use these options
every time.

Hello all,
I have just tried to compile a simple "Hello World" program in C,
but it
failed to do so.
source code:
#include <stdio.h>
int main()
{
printk("Hello World!\n");
getchar();
return 0;
}
error message:
------@--------------:~/Programs/C$ gcc hello.c
hello.c:1:20: error: stdio.h: No such file or directory
hello.c: In function ‘main’:
hello.c:5: warning: incompatible implicit declaration of built-in
function ‘printf’
I then changed 'printf' to 'printk' in the source code and got this
error message only:
------@--------------:~/Programs/C$ gcc hello.c
hello.c:1:20: error: stdio.h: No such file or directory
I'm using a fresh install of Ubuntu Edgy Eft (6.10), and it has gcc
4.1
installed.
