Run configure -help to see what drivers can be built. You should get an output similar to this:. The configure script cannot detect the neccessary libraries and include files if they are not in the standard paths, so it may be necessary to specify these paths using the -I and -L command-line options. On Windows the -I parameter doesn't accept spaces in filenames, so use the 8.

Look at the sections that follow for additional information about required libraries. The MySQL embedded server is a drop-in replacement for the normal client library. You need the MySQL header files and as well as the shared library libmysqlclient.

Depending on your Linux distribution you may need to install a package which is usually called "mysql-devel". After installing Qt, as described in the Installing Qt for X11 Platforms document, you also need to install the plugin in the standard location:. You need to get the MySQL installation files. EXE and choose "Custom Install". If you are not using a Microsoft compiler, replace nmake with make in the line above. Including "-o Makefile" as an argument to qmake to tell it where to build the makefile can cause the plugin to be built in release mode only.

If you are expecting a debug version to be built as well, don't use the "-o Makefile" option. In this example, Qt 4. After connecting to the Oracle server, the plugin will auto-detect the database version and enable features accordingly. It's possible to connect to a Oracle database without a tnsnames. This requires that the database SID is passed to the driver as the database name and that a hostname is given. Usually, this means that the database server will use the user authentication provided by the operating system instead of its own authentication mechanism.

Leave the username and password empty when opening a connection with QSqlDatabase to use the external credentials authentication.

Here is an example:. Build the plugin as follows here it is assumed that Oracle Client is installed in C: When you run your application you will also need to add the oci. You should use native drivers in preference to the ODBC driver where they are available. ODBC support can be used as a fallback for compliant databases if no native drivers are available.

For Unix systems there are some implementations which must be installed first. Some ODBC drivers claim to be version 2.

The QODBC plugin therefore checks whether the data source can be used after a connection has been established and refuses to work if the check fails. Do this at your own risk! To avoid this problem, instruct the ODBC driver to behave as a 3. Note that this will affect multiple aspects of ODBC driver behavior, e. Before setting this connect option, consult your ODBC documentation about behavior differences you can expect. Some drivers don't support scrollable cursors.

Supported Databases

In that case case only queries in forwardOnly mode can be used successfully. With Microsoft SQL Server the result set returned by a stored procedure that uses the return statement, or returns multiple result sets, will be accessible only if you set the query's forward only mode to forward using QSqlQuery:: On Windows NT based systems, this is the default. It is recommended that you use unixODBC. You can find the latest version and ODBC drivers at http: You need the unixODBC header files and shared libraries.

The ODBC header and include files should already be installed in the right directories. You just have to build the plugin as follows:. We recommend that you use a client library from version 7. For more information about PostgreSQL visit http: Unicode is automatically used if the server supports it. Note that the driver only supports the UTF-8 encoding. If your database uses any other encoding, the server must be compiled with Unicode conversion support.

Building the Drivers Using Configure

Unicode support was introduced in PostgreSQL version 7. Install the appropriate PostgreSQL developer libraries for your compiler.

That is why in my first post I showed the mysql libs, their locations and otool -L to show the plugin points to the right libmysqlclient. I remember jyavenard's name from back when I was setting up my mythtv 0.

Back then I built mythtv from sources with osx-packager and all of the apps were self contained. I downloaded MythFrontend. I was able to copy frontend settings from my 0. I've never tried that. There have been very few commits to the 0.
