Now that the cross compiler is installed on the DAQ machine it is time to try and compile the simplest program, download it to the gumstix, and see if it will run.

			Here is the source code

			<pre>
			#include <stdio.h>

			int main(void)
			{
			printf("Hello Gummy\n");
			return 0;
			}

			</pre>


			I put it on the DAQ machine in the subdirectory

			~/gumstix/Hello/ Hello.c

			I compiled it with the command

			~/gumstix/gumstix-oe/tmp/cross/arm-angstrom-linux-gnueabi/bin/gcc Hello.c



			It made the binary a.out

			I copied it over to the gumstix using scp

			scp a.out root@134.50.3.175:

			and it ran

			root@gumstix-custom-verdex:~$ ./a.out
			Hello Gummy
