QPSQL driver not loaded Qt

Question

I have some problems 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 in the variables the paths PATHto:

PostgreSQL\9.3\bin
PostgreSQL\9.3\lib
PostgreSQL\9.3\include

I will also copy the folder sqldriversto Debug. Also tried copy dll drom from this folder to Debug. Does not work.

Answer 1

I came here googling because I had the same problem on Windows.

In my case, to solve the problem, I had to install PostgreSQL for Windows 32 bits, since my Qt target was 32 bits MinGW.

, PATH bin lib PostgreSQL, Qt .dlls.

@SET PATH=C:\Program Files (x86)\PostgreSQL\9.6\bin\;C:\Program Files (x86)\PostgreSQL\9.6\lib\;%PATH%

PATH Qt Creator Qt Creator Build Environment Projects.
