MySQL Connector/C++ is available as a static or dynamic library to use with your application. This section describes how to link the library to your application.
To avoid potential crashes, the build configuration of MySQL Connector/C++ should match the build configuration of the application using it. For example, do not use the release build of MySQL Connector/C++ with a debug build of the client application.
The MySQL Connector/C++ static library file is
mysqlcppconn-static.lib. You link this
library statically with your application. Also link against the
libmysql.lib. At runtime, the application
will require access to
The MySQL Connector/C++ dynamic library file is
mysqlcppconn.dll. To build your client
application, link it with the file
mysqlcppconn.lib. At runtime, the application
will require access to the files
Building a MySQL Connector/C++ Application with Microsoft Visual Studio
The initial steps for building an application to use either the static or dynamic library are the same. Some additional steps vary, depend on whether you are building your application to use the static or dynamic library.
Select File, New, Project from the main menu.
In the wizard, select Visual C++, Win32. From Visual Studio Installed Templates, select the application type Win32 Console Application. Enter a name for the application, then click OK, to move to the Win32 Application Wizard.
In the Win32 Application Wizard, click Application Settings and ensure the defaults are selected. The radio button Console application and the check box Precompiled headers are selected. Click Finish to close the wizard.
From the drop down list box on the toolbar, change from the default Debug build to the Release build.
From the main menu select Project, Properties. This can also be accessed using the hot key ALT + F7.
Under Configuration Properties, open the tree view.
Select C++, General in the tree view.
Ensure that Visual Studio can find the MySQL include directory. This directory includes header files that can optionally be installed when installing MySQL Server.
In the Additional Include Directories
text field, add the MySQL
Also set the location of additional libraries that Visual
Studio needs to build the application. These are located in
lib/opt directory, a
subdirectory of the MySQL Server installation directory.
In the tree view, open Linker, General, Additional Library Directories.
lib/opt directory into the
Additional Library Directories text
field. This enables the library file
libmysql.lib to be found.
The remaining steps depend on whether you are building an application to use the MySQL Connector/C++ static or dynamic library. If you are building your application to use the dynamic library, see Dynamic Build. If you are building your application to use the static library, carry out the following steps:
Open Linker, Input, Additional Dependencies.
CPPCONN_PUBLIC_FUNC is defined
to declare functions to be compatible with an application that
calls a DLL. If you are building an application to call the
static library, ensure that function prototypes are compatible
with this. In this case, define
CPPCONN_PUBLIC_FUNC to be an empty string,
so that functions are declared with the correct prototype.
In the Project,
Properties tree view, under
CPPCONN_PUBLIC_FUNC= into the
Preprocessor Definitions text field.
Make sure you enter
CPPCONN_PUBLIC_FUNC, so that it
is defined as an empty string.
If you are building an application to use the MySQL Connector/C++ dynamically linked library, carry out these steps:
Under Linker, Input,
mysqlcppconn.lib into the
Additional Dependencies text field.
mysqlcppconn.dll must be in the same
directory as the application executable, or somewhere on the
system's path, so that the application can access the MySQL Connector/C++
Dynamic Linked Library at runtime.
mysqlcppconn.dll to the same
directory as the application. Alternatively, extend the
PATH environment variable using
Alternatively, you can copy
mysqlcppconn.dll to the Windows
installation Directory, typically
