QMYSQL driver not loaded on Ubuntu

SGaist

I know where your dlls are. If using 64bit, the question is: is "C:\Program Files\MySQL\MySQL Server 5.6\lib" contained in the PATH environment variable in the Run section on the Project panel in Qt Creator ?

I didn't ask you to run ldd on /bin/date but on your Qt 5.2.0 libqsqlmysql.so

You already have all the information: call "ldd /opt/Qt5.2.0/5.2.0/gcc_64/plugins/sqldrivers/libqsqlmysql.so"

to see what libraries it links to

You have it on the second line:

You have the version 18 and not the 16.

So two solutions here:

find the version 16
build the Qt MySQL plugin yourself with this version of the client library (best)

Sorry , but can you help me for find or build qt mysql plugin ?
I run this command : root@Gigabyte-Z68P-DS3:/opt/Qt5.2.0/5.2.0/Src/qtbase/src/plugins/sqldrivers/mysql# qmake "INCLUDEPATH+=/usr/include/mysql" "LIBS+=-L/usr/lib/mysql -lmysqlclient_r" mysql.pro

I think my command is not true ! in QT 5.2 any folders and roots is different...

SGaist

did you call make after that ?

? Offline

I run first this command : root@Gigabyte-Z68P-DS3:~# cd /opt/Qt5.2.0/5.2.0/Src/qtbase/src/plugins/sqldrivers/mysql

after :

Are you sure you are using the right qmake ?

Also, why are you developing as root ?
