gcc not compiling

[Dotan Cohen]

I'm just getting started in programming C. My first attempt:
#include < stdio.h>
void main () {
    printf("\nHello World!\n");
}

Threw this error:
[dotancohen@localhost ~]$ gcc hello.c
hello.c:1:20: error:  stdio.h: No such file or directory
hello.c: In function 'main':
hello.c:3: warning: incompatible implicit declaration of built-in
function 'printf'
hello.c:2: warning: return type of 'main' is not 'int'
hello.c:4:2: warning: no newline at end of file

So I googled for "1:20: error:  stdio.h: No such file or directory"
and found a post that suggests that the answer to the problem is found
in the gcc manual. So I started reading it, but it is long and I'm not
finding anything!

I think that I'm missing a library stdio.h but I don't know where to
find it, and where to put it once I do find it. Or am I completly
wrong? The error message is pretty clear.

^-- extra space needs to be removed.

you have a space between "<" and "stdio" which shouldn't be there.  it
should just read
#include <stdio.h>

i.e., the file it can't find it " stdio.h"

Thanks, I removed the space. I also changed the main function from
void to int, and returned 0 at the end, as Brian D. McGrew suggested.
It works now. In five minutes I got three helpful answers- you guys
are great! Thanks everybody!

hi

if you remove the blank between "<" and "stdio.h>" it will compile.

Doltan,

I see long discussions about stuff. In case no one has actually answered
your question, the problem is you have a space between "<" and "stdio.h"
and so the compiler is looking for a while with an embedded space in it.

Get rid of that space and your program should compile (though you'll get
some of the same warnings).

Thanks, actually, it was answered several times! I removed the space
and made some other changes that were suggested here, and it compiled.

I also enjoyed the discussion regarding int vs. void and properly
returning a 0 after the function ends. I should get to class a little
more prepared than the next guy! Thank you all!

Well, for starters, it probably doesn't like the space between the <
and the s in < stdio.h>
Thats what is occasionally known as  typu  :-)

'C' being a strongly typo'd language....
