Jason, Hello, I am also new to mapserver (one week, approximately). I
also had the snow problem. However, from my experience, it is definately
best to start out with one layer at a time and then add on (Thanks for
your advice Paul :) - plug for my office-mate)
There is a stand-alone command that is called 'shp2gif' that is like a
de-bugging command. It can be found in the ms_3.2 directory after
installation.
The syntax looks like this: shp2gif -m state.map -o state.gif
Running this on your mapfile will make a gif image of either
snow or your first layer :) - hopefully your first layer. If it does not
run completely, it will give you an error message of what is not working
so you can start to debug. I kept my file very simple, not quite as
complex as the demo (hey - it was complex for me anyhoo) and am going to
then be adding layers to it.
I wanted to make sure to get at least one layer working first.
Just a suggestion from someone who made the suggestion to me-
