Hi, I'm getting the same error on my version. I seem to remember something about a path issue with a newer version of OGR, but I could be wrong.
Assefa: do you remember what the cause of this is? ..Tom > -----Original Message----- > From: UMN MapServer Users List > [mailto:[EMAIL PROTECTED] On Behalf Of Scott Wittenburg > Sent: 17 January, 2008 2:59 PM > To: [email protected] > Subject: [UMN_MAPSERVER-USERS] Trouble with > OGC Workshop WFS Client Demo > > Hello All, > > I'm new to mapserver, and I'm having trouble getting one of > the OGC Workshop demos to work.
