[Mapserver-users] open failed ogr connection

[Andreas Koeberle]

Hi Frank,
I try it with a newer version that I found in the listarchive 
(http://www.maptools.org/dl/mapserver-4.1-dev-win32-php4.3.4.zip). These 
version seems to work with the gdal12.dll (2 April 2004). But I got the 
same error with mapserver and shp2img. I use a system DNS to my ODBC 
source.
