trying to get demo to run

[Douglass Davis]

I am a new user, and I have been having troubles trying to get Mapserver 
to do anything meaningful, so I am now just trying to get a simple demo 
to work.

The Demo is located here:
http://ms.gis.umn.edu/new_users/index_html#mapserver-overview

Whenever I run it, I get a 500 error.  In my error log I get this:
[Wed Jul 27 10:49:22 2005] [error] [client 127.0.0.1] Premature end of 
script headers: c:/program files/apache group/apache/cgi-bin/mapserv.exe

I am using the Windows XP version of mapscript:

C:\Documents and Settings\Douglass Davis>mapserv -v

OUTPUT=PDF
 OUTPUT=SWF SUPPORTS=PROJ SUPPORTS=FREETYPE SUPPORTS=WMS_SERVER

C:\Documents and Settings\Douglass Davis>php --version

PHP 4.4.0 (cgi-fcgi) (built: Jul 11 2005 16:13:04)

Here is the first part of the mapfile

I changed everything that the demo said needed to be changed.

Here's part of the index file (the only part that it said needs changing):

<!-- If you renamed the MapServer CGI program, or if your CGI directory 
is different from /cgi-bin, update the value of "action" below.  This 
could be "/scripts/mapserv.exe" for Windows and IIS users. -->
<form method=GET action="/cgi-bin/mapserv">

<!-- Change the "value" of map to the full path and name of your 
mapfile.  For Windows users, add the drive letter in front of the path.  
ex: "c:/inetpub/wwwroot/itasca/demo.map" -->
<input type="hidden" name="map" value="C:/Program Files/Apache 
Group/Apache/htdocs/mapserver/itasca/demo.map">

<input type="hidden" name="layer" value="lakespy2">
<input type="hidden" name="layer" value="dlgstln2">
<input type="hidden" name="zoomsize" value=2>

<!-- The value of the parameter below should be the same as the form 
action above -->
<input type="hidden" name="program" value="/cgi-bin/mapserv">

<! -- Replace the value of the parameter below to the full path to the 
temporary directory where MapServer will write temporary files.  Make 
sure the web user account can write to this directory.-->
<input type="hidden" name="map_web_imagepath" value="C:/tmp/ms_tmp/">

<!-- Replace the value of the parameter below with the virtual directory 
path (in Apache parlance, the Alias) of your imagepath.  If your 
imagepath was created under the htdocs or wwwroot directories, the value 
shouldn't have to be changed. -->
<input type="hidden" name="map_web_imageurl" value="/ms_tmp/">


Does any one know why this is not working?
