[Mapserver-users] mapserver crashes at a png file

[Vincent Schut]

Carsten,

Assuming you run linux, can you run shp2img on your mapfile as a test?
Or use mapserv from the commandline: ./mapserv 
"QUERY_STRING=map=/path/to/your/mapfile.map&mode=map"
which should ouput the image to stdout so you should see a bunch of ascii 
codes in your terminal. Or something like a segfault...
If there is a segfault, run the same command through the debugger:
gdb mapserv
run "QUERY_STRING=map=/path/to/your/mapfile.map&mode=map"
[gdb reports segfaulting ]
backtrace

this will give you some clues about the function/library that generates the 
error. Assuming that your version of mapserver has been compiled with 
debugging symbols, of course.

If you run windows, I cannot help you I'm afraid... But others can, so keep 
posting to this list!

Regards,
Vincent Schut.
