Mac --> QSqlDatabase: QMYSQL driver not loaded
-
Sorry, I mislead you, it must be set as environment variable when you run your application. Go to Projects, select the run panel, Run environment, and add that variable there
-
I place my variable and I have a lot of stuff :

Then how did you install MySQL ?
-
Ok, so where on your system can you find a library named libmysqlclient.dylib ?
-
Ok ! Here we have it now. Please use install_name_tool to update the QtSql library in the framework
-
In my folder I have theses files :
@bash-3.2$ cd usr/local/mysql-5.6.19-osx10.6-x86//lib/
bash-3.2$ ls
libmysqlclient.18.dylib libmysqlclient_r.dylib
libmysqlclient.a libmysqld-debug.a
libmysqlclient.dylib libmysqld.a
libmysqlclient_r.18.dylib libmysqlservices.a
libmysqlclient_r.a plugin@What will I do ?
-
using install_name_tool, correct the path /opt/local/lib/mysql55/mysql/libmysqlclient.18.dylib in libqsqlmysql.dylib with /usr/local/mysql-5.6.19-osx10.6-x86//lib/libmysqlclient.18.dylib
-
install_name_tool -change old_path new_path libqsqlmysql.dylib

Hello SGaist,
I have tried your solution, with this instruction:
install_name_tool -change /opt/local/lib/mysql55/mysql/libmysqlclient.18.dylib /Applications/mampstack-5.4.26-0/mysql/lib/libmysqlclient.dylib libqsqlmysql.dylibbut during debug I receive this message:
@

QSqlError(2005, "QMYSQL: Unable to connect", "Unknown MySQL server host 'localhost:3306' (2)") @I have followed all step that you wrote previously!
Can you help me? -
Is your server running ?
Also, if it was deployed correctly, you should need to correct the path by hand. The client library should be already copied in your bundle
-
It's not work for my :'(
@install_name_tool -change /opt/local/lib/mysql55/mysql/libmysqlclient.18.dylib /Applications/mampstack-5.4.26-0/mysql/lib/libmysqlclient.dylib libqsqlmysql.dylib
error: /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/install_name_tool: can't open file: libqsqlmysql.dylib (No such file or directory)
@what I must to do ? I'm on Yosemite now.
-
As silly as it may sound, use the correct path to libqsqlmysql.dylib
-
I don't understand what you mean.
One other thing when I run my project I have these lines :
@QSqlDatabase: QMYSQL driver not loaded
QSqlDatabase: available drivers: QSQLITE QMYSQL QMYSQL3 QODBC QODBC3 QPSQL QPSQL7@If it's available why it's not loaded.
-
@can't open file: libqsqlmysql.dylib (No such file or directory)@
You didn't run the command in the right folder since libqsqlmysql.dylib could not be found.
That generally happens when the plugin can't be loaded because e.g. it can't find one of the its dependencies
