[mapserver-users] Memory access error when accessing Oracle database

Mon Oct 22 08:10:37 PDT 2012

Hi,
I try to use MapServer 6.2.0-rc1 to display data from an Oracle database.

*mapserv -v*
MapServer version 6.2.0-rc1 OUTPUT = GIF OUTPUT = PNG OUTPUT = JPEG 
SUPPORTS = PROJ SUPPORTS = AGG SUPPORTS SUPPORTS = DG = FREETYPE 
SUPPORTS = ICONV SUPPORTS = WMS_SERVER SUPPORTS = WMS_CLIENT SUPPORTS = 
WFS_SERVER SUPPORTS = WFS_CLIENT SUPPORTS = WCS_SERVER SUPPORTS = 
FastCGI SUPPORTS = THREADS SUPPORTS = GEOS INPUT = JPEG INPUT = 
ORACLESPATIAL INPUT = OGR INPUT = GDAL INPUT = SHAPEFILE

*Error message:*

When I use the Connectiontype OGR I get a *different error*:

As far as I see it, the problem is the lack of SRID (zero instead of 4326)
