Ok great, it works now. I was missing the murgaLua to link.

1) ln -s /home/sun/Download/murgaLua/bin/Linux/murgaLua /usr/bin/murgaLua

2) vi example1.lua

fltk.fl_message("Hello Word")
print("Hello World")

3) $murgaLua example1.lua

Works great.

Well you haven't included the fltk module.
The '#' is a bit worrisome too; are you running this as root?

Hi all,

I want to ask the user to type a keystroke, and get that keystroke without the
user needing to press Enter. How do I do that in LUA?

In Perl you do it like this:

sub getch_unix($)
        {
        my $nodeSession = shift;
        my($GETCH_STYLE) = $nodeSession->getAttribute('getch_style');
        $GETCH_STYLE = 1 unless defined ($GETCH_STYLE);
        my($key);
        if ($GETCH_STYLE)
                {
                system "stty cbreak </dev/tty >/dev/tty 2>&1";
                }
        else
                {
                system "stty", '-icanon', 'eol', "\001";
                }

        $key = getc(STDIN);

        if ($GETCH_STYLE)
                {
                system "stty -cbreak </dev/tty >/dev/tty 2>&1";
                }
        else
                {
                system "stty", 'icanon', 'eol', '^@'; # ASCII null
                }
        return($key);
        }

For the time being I just need to do it in Linux/Unix/BSD, but it would be
nice to know how to do it in Windows too. Anyone know?

Thanks
