I have some trouble when I want to add a database.
_dataBase = QSqlDatabase::addDatabase("QPSQL");
After calling this method I have an error:
QSqlDatabase: QPSQL driver not loaded
QSqlDatabase: available drivers: QSQLITE QMYSQL QMYSQL3 QODBC QODBC3 QPSQL QPSQL7
I include to PATH
variable paths to:
PostgreSQL\9.3\bin
PostgreSQL\9.3\lib
PostgreSQL\9.3\include
Also I copy folder sqldrivers
to Debug
folder. Also tried to copy dlls drom this folder to Debug
. Doesn't work either.
I came here googling because I had the same problem in Windows.
In my case to solve the issue I had to install PostgreSQL for Windows 32 bits since my Qt target was MinGW 32 bits.
Additionally, I had to add the PATH
to the PostgreSQL bin and lib directories so Qt could find the right .dlls
.
@SET PATH=C:\Program Files (x86)\PostgreSQL\9.6\bin\;C:\Program Files (x86)\PostgreSQL\9.6\lib\;%PATH%
The PATH
can be set before launching Qt Creator or using the Qt Creator itself via the Build Environment
in the Projects
pane.
