Qt psgl driver not loaded

HorstJ

Hi All,

sorry being the thousandth asking this, but none of the solutions helped me. I have a fresh postgres 9.4 x86 install and build the qt psgl plugin by myself. Then I copied qsqlpsqld.dll to myapppath/debug/sqldrivers and set Path to my postgres bin directory.

Unfortunately I only get the well known "PSQL driver not loaded"

Dependency Walker (seem to be missing, but for every dll I checked):
api-ms-win...
dcomp.dll
gpsvc.dll
ieshims.dll

Debug output from shell:

QFactoryLoader::QFactoryLoader() checking directory path "C:/PROGRA~4/Qt/5.3/mingw482_32/plugins/sqldrivers" ...
QFactoryLoader::QFactoryLoader() checking directory path "myapppath/debug/sqldrivers" ...
QFactoryLoader::QFactoryLoader() looking at "myapppath/debug/sqldrivers/libqsqlpsqld.a"
"Plugin verification data mismatch in 'myapppath/debug/sqldrivers/libqsqlpsqld.a'"
not a plugin
QFactoryLoader::QFactoryLoader() looking at "myapppath/debug/sqldrivers/qsqlpsqld.dll"
Found metadata in lib myapppath/debug/sqldrivers/qsqlpsqld.dll, metadata=
{
"IID": "org.qt-project.Qt.QSqlDriverFactoryInterface",
"MetaData": {
"Keys": [
"QPSQL7",
"QPSQL"
]
},
"className": "QPSQLDriverPlugin",
"debug": true,
"version": 328450
}

Got keys from plugin meta data ("QPSQL7", "QPSQL")
QSqlDatabase: PSQL driver not loaded
QSqlDatabase: available drivers: QPSQL QPSQL7

Any ideas are welcome ;-)

Hi,

Are you starting your program from Qt Creator ? And where did you modify your PATH variable ?

HorstJ

HI,
I tried both ways, creator and windows shell.
I have changed the PATH variable global (windows settings) and do not override it in creator.

You should rather change the one from Qt Creator. The PATH environment variable should stay as clean as possible.
