Hello everyone
I managed to solve the issue. I figured out that maybe the problem is
that the apache user (under which mapserver runs as CGI) can't read my
epsg file. I got suspicious since my epsg file is actually a symlink to
the real file (which is in /usr/share/proj/nad/epsg). I deleted the
symlink and created a hardlink instead and presto! the error went away!
ln /usr/share/proj/nad/epsg /usr/share/proj/epsg
Thanks for the help, guys
Regards,
Adrian

Hmm, any idea on this one? How can I find out if proj is trying to read
the epsg file? I'm thinking of using strace to see what files it tries
to open, but I don't know what syntax to use to try to project from 4326
to 900913...
Just to clarify:
- Your data is in wgs84 (epsg:4326)
- you want to serve mercator projection (epsg:900913)
A few questions:
- are there any errors in the capabilities document?
- did you tried to use mapserver logging (MS_ERRORFILE) and high debug
level (DEBUG 5)
- could you try to use shp2img, maybe this gives you a bit more information?
- did you compile MapServer and the dependencies by yourself?
- what MapServer version do you use?
- do you have Proj4 installed? (OpenLayers doesn't use the same lib, it
uses the javascript lib)
I hope it does not look like keeping you busy, but without further
information its difficult to help.
Lars
