Hi to all,
I replaced my version of Mapserver with a precompiled one. I also installed
the latest version of gdal11.dll and ogrinfo from the OpenEV_FW zip.
As suggested by Frank Warmerdam I used the following SrcDataSource tag in
the virtual file:
<SrcDataSource>ODBC:MGWI_MAPSERVER</SrcDataSource>. MGWI_MAPSERVER is the
DSN for my ODBC data source.
Here is the orginfo output:
D:\WebScripts\MapServer>ogrinfo --formats
Loaded OGR Format Drivers:
-> "ESRI Shapefile" (read/write)
-> "UK .NTF" (readonly)
-> "SDTS" (readonly)
-> "TIGER" (read/write)
-> "S57" (read/write)
-> "MapInfo File" (read/write)
-> "DGN" (read/write)
-> "VRT" (readonly)
-> "AVCBin" (readonly)
-> "REC" (readonly)
-> "Memory" (read/write)
-> "GML" (read/write)
-> "ODBC" (read/write)
-> "OGDI" (readonly)
-> "FMEObjects Gateway" (readonly)
D:\WebScripts\MapServer>ogrinfo
D:\webCGCq\lcnp\mapserver_demo\maritimes\data\shp\geo83\mgwi.ovf
ERROR 4: Update access not supported for VRT datasources.
Had to open data source read-only.
INFO: Open of
`D:\webCGCq\lcnp\mapserver_demo\maritimes\data\shp\geo83\mgwi.ovf'
using driver `VRT' successful.
1: MGWI_TBLLOC (Point)
When I execute Mapserver I got the following message:
msDrawMap(): Image handling error. Failed to draw layer named 'MGWI_TBLLOC'.
msOGRFileOpen(): OGR error. Open failed for OGR connection `mgwi.ovf'. File
not found or unsupported format.
Thanks for the help
Héryk

Julien,
Just because I do not know all the steps you have done, can you tell me
if you were able to have some output form "ogrinfo" command?
