QMYSQL driver not loaded (but built)
-
I followed this guide (http://www.seppemagiels.com/blog/create-mysql-driver-qt-windows) and built the dlls and .a files. I put them in the spot the guide said (.../qtsources/4.8.1/src/plugins/sqldrivers), my mingw/bin folder, and also my qtsdk/desktop/qt/4.8.1/mingw/bin folder. However, when I run his test application, the only results I'm getting from QSqlDatabase::drivers() are "QSQLITE", "QODBC3", and "QODBC". I'm supposed to be getting a result for QMYSQL. What do I need to do? I tried adding INCLUDEPATH and LIBS in my project.pro file to point to any folder that had the dlls I made, but that didn't change anything.

I have the same problem, I'm compiling the dylib and are already in the right repectoire. But when I compile I get the message Error
QMYSQL driver not loaded
QSqlDatabase: available drivers: QSQLITE QODBC QODBC3 QPSQL QPSQL7
QSqlError(-1, "Driver not loaded", "Driver not loaded")I'm using Qt 5.0.2 and Qt Creator 2.7.1 for Mac OS X 10.7.5
Thanks you -

Hi,
The loader can't find libmysqlclient. Do you have it in your PATH ?
-
Let me rephrase that:
In your PATH environment variable, do you have the path pointing to the folder where libmysqlclient.dylib can be found ?
-
Two possibilities:
Update you .profile and start QtCreator from the console using :
@open myproject.pro@Updated the value in the Run section of the Project panel
