PS
I copied SYSNTFY.DLL, IESHIMS.DLL and GPSVC.DLL because Dependency Walker mentioned them as dependent for my app.

Qsqldatabase Qpsql Driver Not Loaded

Did you compile the release and debug versions of the plugin? The output of the dependency walker looks like you work with the debug version. You should have qsqlpsql4.dll and qsqlpsqld4.dll in the %QTDIR%pluginssqldrivers directory. You can check the plugin path that is used in your program with: QString QLibraryInfo::location ( QLibraryInfo::PluginsPath );

i compiled both qsqlpsql4.dll/qsqlpsqld4.dll and plugin path is correct(%QTDIR%plugins). Thank for the answer.bmeric29 дек. 102010-12-29 20:02:45

The link you mentioned above also talks about the need to have (%pgsql)bin in your path.hmuelner29 дек. 102010-12-29 20:08:33

I compiled both release and debug versions, and the plugin path used is correct, yet I am still having the same issue. Any other ideas?Jordan10 июн. 112011-06-10 12:37:31

Try to use the debug version with VS2008 and have a look at the output window, where all loaded dlls are listed with the full path. Are the paths correct?hmuelner11 июн. 112011-06-11 16:45:27
