====== Hello cc65! ======

Here we go again - the mighty piece of code that never dies...

<code>
#include <stdio.h>

void main(void)
{
	printf("Hello, world!\n");
}
</code>

You save the above programming masterpiece using your favourite text editor as hello.c and the fun begins... You probably should read the excellent [[http://www.cc65.org/doc/|cc65 documentation]] or at least the [[http://www.cc65.org/doc/intro.html|introduction section]] before continuing. This will make things more clear and structured in your mind :-) For now, we assume that you know what are the [[http://www.cc65.org/doc/intro-1.html#ss1.3|translation phases]] (or you just don't want to know that) and we go the easy way, using cc65's [[http://www.cc65.org/doc/cl65.html|Compile & Link utility]]. The beauty of this utility is that single command:

<code>
$ cl65 hello.c
</code>

should create for you one object file named "hello.o" and one (C64) executable named "hello":

<code>
$ ls -l
total 24
-rw-r--r--  1 user  staff  2758 17 cze 20:05 hello
-rw-r--r--  1 user  staff    68 17 cze 19:38 hello.c
-rw-r--r--  1 user  staff   568 17 cze 20:05 hello.o
$
</code>

C64 is the default target for many cc65 tools. If you need to have your pride compiled for a different [[cc65:mainpage#target_platforms|target platform]] you need to add a switch to the command line:

<code>
$ cl65 -t apple2 hello.c
</code>

creates executable file for Apple ][ machines. For a complete list of supported target platforms, please refer to the [[http://www.cc65.org/doc/|cc65 documentation]] and [[http://www.cc65.org/doc/ld65.html|ld65]] [[http://www.cc65.org/doc/ld65-2.html#ss2.2|linker options]] for setting the target.
