fast-cgi

[huub fleuren]

Hi List,

I managed to compile mapserver4_6beta1 from cvs with the latest maporaclespatial.c
(with Microsoft (R) 32-bit C/C++ Optimizing Compiler Version 12.00.8168 for 80x86)
using makefile.vc that comes with the source distribution 4.4.2

fcgi-2.4.0
gdal-1.2.6
gdwin32
mapserver.head
oracle10g
proj-4.4.9
regex-0.12

The resulting server works with the demodata (canada) and also a
shapefile in the used EPSG:28992

But, I get no image if i use OracleSpatial layers

compare:
(the black lines are a from a shapefile).

below some information
the only difference is WMS CLIENT WFS SERVER/CLIENT
i don't expect to need it
