The OGR provider present in 3.4.0 GA is apparently missing the fix from r4525, which prevents it from working with MapGuide? Enterprise 2010.
Below are the error log statements from executing the "Test" operation on MapGuide?:
File from the standalone OGR download (file version 3.4.0.4701):
<2009-04-20T08:54:03> 3620 MapGuide? Maestro 127.0.0.1 Administrator
Error: An unclassified exception occurred.
StackTrace?:
File from the WinSDK download (file version 3.4.0.4701):
<2009-04-20T08:56:17> 2016 MapGuide? Maestro API 127.0.0.1 Administrator
Error: An unclassified exception occurred.
StackTrace?:
If I build from source, without the fix from r4525 I get the exact same errors.
If I include the fix from r4525, everything works as expected.
I have attached my own build of the OGR provider, which works.
