[Mapserver-users] open failed ogr connection

[Paul Dymecki]

Hi,
   I'm just trying to get OGR with ODBC working  on the win32 binaries.  I
tried the shp2img on my map file though and get the following error
message..

>C:\msapps>shp2img -m c:\apache2\htdocs\ms4w\apps\cbm\map\cbm.map
>msProcessProjection(): Projection library error. invalid projection system
error
 >number <br>


Would i have to recompile mapserver with OGR??
thx,
Paul
