MYSQL Drivers - How to install on Mac osx 10.7?
-
This has got to be the most frustrating install for what is a very popular database.
I have searched and read and searched and read for 2 days now about how to install the MYSQL drivers, and still no joy.I followed the instructions on how to build for mac osx which is the platform I am using
so I ran qmake $QTDIR/qmake "INCLUDEPATH+=$MYSQLPATH/include" "LIBS+=-L$MYSQLPATH/lib -lmysqlclient_r" ./mysql.pro
and i got the following output:
@make -f Makefile.Debug

What am i doing wrong here?

Hi,
I have not built Qt from sources - i downloaded and installed the SDK 1.2.1, and used the maintenance tool to install the sources, I then proceeded to build the mySQL drivers.
any ideas?

Hi,
I have managed to compile both debug and release versions, 2 files which have been placed into the plugins folder:
libqsqlmysql_debug.dylib
libqsqlmysql.dylib~/QtSDK/Desktop/Qt/4.8.1/gcc/plugins/sqldrivers/
in my project file for my database application i am writing, i have added 'sql'
@QT += core gui sql@
in my main window constructor - i have the code to open the database:
@// Configure Database connection
db = QSqlDatabase::addDatabase("QMYSQL");
db.setHostName("localhost");
db.setDatabaseName("WorkforceManager");
db.setUserName("root");
//db.setPassword("abc1234");
db.setPort(3306);
DBOk = db.open();
qDebug() << db.drivers();
qDebug() << db.lastError();@This compiles without any problems. However, when i run the application, it is saying the following:
@QSqlDatabase: QMYSQL driver not loaded
QSqlDatabase: available drivers: QSQLITE QODBC3 QODBC QPSQL7 QPSQL
("QSQLITE", "QODBC3", "QODBC", "QPSQL7", "QPSQL")
QSqlError(-1, "Driver not loaded", "Driver not loaded")@do i need to tell Qt somehow about the new driver?

finally worked it out!!
final step after all of that you need to run the install-name-tool:
@install_name_tool -change libmysqlclient.18.dylib /usr/local/mysql/lib/libmysqlclient_r.18.dylib libqsqlmysql.dylib@
