[mapserver-users] OK, another blank gif-file...

[Stephen Lime]

Remeber that layers are OFF by default with the CGI program unless they are defined
as "STATUS DEFAULT". The shp2gif utility reads the map file "as-is". So, since none
of you layers are ON for the CGI version you get a white image. To fix? Set their status
to DEFAULT or explicitly turn them on in the URL (&layer=bebauung1&layer=ortho-1).

I setup a .map-file that creates a gif-file containing an orthophoto and a
simple shapefile using "shp2img".
This works just fine, but when I try to invoke the exact same .map-file with
the "mapserv"-program using

http://130.75.85.56/cgi-bin/mapserv?map=/home/httpd/cgi-bin/test2.map&templa 
te=/home/httpd/html/test1.htm&imgext=3480000.000+5399000.000+3481557.000+540
0740.000

...for example, the gif-files stay white!!.
There cannot be anything wrong with directories or missing files, since the
.map-file is already tested on that same machine.
This is also true for the map-EXTENT.

I also tried to install binaries for GD, libtiff and libjpeg using the
"rpm"-command on redhat 6.2 for SPARC, but it always said everything was in
place just fine already, since I had compiled these before on that machine.

I also tried to save the orthophoto as unpacked gif, greyscale, of course,
but at least the shapefile should show up, right?
It even works with the windows-"shp2img"!!


-> Here is the .map-file:

    END # CLASS OBJECT

END # end of mapfile



-> These are the last two log-entries:

Any ideas on this one?
What does the "0" after the map-name "TEST2-" mean?
