Hi,

I'm currently testing an Alpha Release of mapserv 3.5. with GDAL library
support

MapServer version 3.5 (pre-alpha) OUTPUT=GIF OUTPUT=PNG OUTPUT=JPEG
OUTPUT=WBMP
SUPPORTS=PROJ SUPPORTS=TTF SUPPORTS=WMS INPUT=TIFF INPUT=EPPL7
INPUT=JPEG INPUT=
GDAL INPUT=SHAPEFILE

I have one georeferenced tif image which is in AGD66/AMG Zone 55
(EPSG:20255) and a would like to output this as WGS84/Geographic
(EPSG:4326)

The capabilities document shows the layer okay (and seems to have
generated it's own LatLonBoundingBox values - I assume from the
reprojection?).  There are infact 2 layers.


http://maps-dev.socialchange.net.au/cgi-bin/wms?request=capabilities

    <Layer queryable="0">
      <Name>barellan</Name>
      <Title>barellan</Title>
      <SRS>EPSG:20255</SRS>
      <LatLonBoundingBox minx="146.559" miny="-34.2968" maxx="146.586"
maxy="-34.2796" />
      <BoundingBox SRS="EPSG:20255"
                  minx="459415" miny="6.20674e+06" maxx="461936"
maxy="6.20484e+06" />
    </Layer>

When I try to use a mapserv getMap request (or wms request - which by
the way I know works okay as I've tested it with a straight forward
Geographic to Geographic on a georeferenced tif file):

http://maps-dev.socialchange.net.au/cgi-bin/wms?VERSION=1.1.0&REQUEST=GetMap&LAYERS=landsat&WIDTH=300&HEIGHT=300&BBOX=144.41,-37.74,146.95,-35.72
 (works okay)

http://maps-dev.socialchange.net.au/cgi-bin/wms?VERSION=1.1.0&REQUEST=GetMap&LAYERS=barellan&WIDTH=300&HEIGHT=300&BBOX=146.559,-34.2968,146.586,-34.2796
 (get error)

I get the following error:

<?xml version='1.0' encoding="UTF-8" standalone="no" ?>
<!DOCTYPE ServiceExceptionReport SYSTEM
"http://www.digitalearth.gov/wmt/xml/exception_1_1_0.dtd">
<ServiceExceptionReport version="1.1.0">
<ServiceException>
msDrawRasterLayer( TIFF ): General error message. Raster reprojection
supported only with the GDAL library.
</ServiceException>
</ServiceExceptionReport>

Can anyone tell me what the problem maybe?  The GDAL library being used
id v1.1.5

Thanks,

Trem
