No such file or directory

[rocket_c]

#include <stdio.h>#include <stdlib.h>
#include <string.h>
#include <strings.h>

I just download Xcode and then run on terminal. The editor is using TeXshop. The file is a .c file. It shows the following errors:

gene.c:1:19: error: stdio.h: No such file or directory
gene.c:2:20: error: stdlib.h: No such file or directory
gene.c:3:20: error: string.h: No such file or directory
gene.c:4:21: error: strings.h: No such file or directory


Why ?

Thanks

You probably didn't install the Xcode program right if you are getting these. Please make and run a hello world program to confirm that your installation works.

gene.c:4:21: error: strings.h: No such file or directory

This probably doesn't exist in your include directory.

It is probably best if you have the header and the relevant source code or object code in your project directory. I am not that familiar with XCode though.

Of course it helps if all lines beginning with # are on there own line, as C requires.
