MySQL Plugin for Raspberry

JoPhoxene

Hi every body.

I am developing an application with QT which will manage a database on a Raspberry and I have some problems with the MySQL plug-in.
To install QT I followed this tutorial : link text
I was able to cross-compile the MySQL plug-in with QT but when I try to load it with the code :

QPluginLoader loader;
loader.setFileName("/usr/local/qt5pi/plugins/sqldrivers/libqsqlmysql.so");
std::cout << "Plugin Loader worked = " << QString::number(loader.load()).toStdString() << std::endl;
std::cout << "Plugin Loader error = "  << loader.errorString().toStdString() << std::endl;

I have this error :

Plugin Loader worked = 0
Plugin Loader error = Cannot load library /usr/local/qt5pi/plugins/sqldrivers/libqsqlmysql.so: (This platform does not support dynamic libraries.)

I tried to recompile the plug-in at least 50 times but I have every time the same issue. Do you know why ?

Thanks

Hi and welcome to devnet,

What parameter did you pass when building Qt ?

What distribution are you running on your Pi ?

JoPhoxene

Hi and thank you for your answer,
When building Qt I configured it like this :

./configure -release -opengl es2 -device linux-rasp-pi2-g++ -device-option CROSS_COMPILE=~/raspi/tools/arm-bcm2708/gcc-linaro-arm-linux-gnueabihf-raspbian/bin/arm-linux-gnueabihf- -sysroot ~/raspi/sysroot -opensource -confirm-license -make libs -prefix /usr/local/qt5pi -extprefix ~/raspi/qt5pi -hostprefix ~/raspi/qt5 -v

On the Raspberry I am running the last version of Raspbian : Raspbian Jessie with PIXEL

Do you have the dependencies installed on your Pi ?

By the way why are you trying to load the plugin by hand ?

JoPhoxene

I think I have installed all dependencies, how to check ?
I load the plugin by hand just for the debug to have the error message.

Problem solved, I reinstall Raspbian and recompile Qt and now everythings works.
