I need help with XCode 7.3

Show all headers | View raw

I only use XCode to compile the occasional "C" program but after
updating to OS X 10.11.4 and XCode 7.3 I cannot even compile a
"hello world" file.

Source:
#include <stdio.h>
#
int	main(int argc, char** argv)
{
	printf("Hello world.\n");
}
}
Result:
bash-3.2$ which cc
/Developer/usr/bin/cc
bash-3.2$ cc hello.c
couldn't understand kern.osversion `15.4.0'
hello.c:1:21: error:  unistd.h: No such file or directory
hello.c: In function 'main':
hello.c:5: warning: incompatible implicit declaration of built-in
	function 'printf'
bash-3.2$

I don't understand what generates the
	couldn't understand kern.osversion `15.4.0'
message and I don't know how to prevent the error.

Can someone help?

TIA
