Hi, I have tried the version MSVC2008 (Win32) -development available today at http://www.gisinternals.com/sdk/ and I have still the same problem. For your information, I'm running GDAL on windows with a PostGIS 2.0 connection on Linux server. I tried many version of GDAL 1.9 and I always have the same problem. The version 1.8 is working very well but I would like to take advantage of the improvements in the last version because I'm working on an important project in Canada where processing time is very important.
Does any developper has an idea for this problem ?
