I didn't realize that the code was designed to talk to an LCD.

I doubt very highly that it's got anything to do with the compiler.

Did you configure the appropriate lines to be serial?

For /dev/ttyS2 you need to do:

modprobe proc_gpio
echo "AF2 in" > /proc/gpio/GPIO46
echo "AF1 out" > /dev/gpio/GPIO47

I ran the tes633 program I compiled and I saw this on my terminal
program connected to /dev/ttyS2:

>This is line 1<
>This is line 2<

with some control characters before and after each line.

How did you connect the LCD to the gumstix (i.e. what exact cables did you =
use?
