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 Connector/C++ should match the build configuration of the application using it. For example, do not use the release build of Connector/C++ with a debug build of the client application.
The Connector/C++ static library file is
mysqlcppconn-static.lib. You link this library
statically with your application. Also link against the files
libmysql.lib. At runtime, the application will
require access to
The 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 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, , 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 , 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 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, . This can also be accessed using the hot key + .
Under Configuration Properties, open the tree view.
Select 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 the MySQL
lib/optdirectory, a subdirectory of the MySQL Server installation directory.
In the tree view, open Linker, General, Additional Library Directories.
lib/optdirectory into the Additional Library Directories text field. This enables the library file
libmysql.libto be found.
The remaining steps depend on whether you are building an application to use the 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_FUNCis 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_FUNCto be an empty string, so that functions are declared with the correct prototype.
In the Project, Properties tree view, under C++, Preprocessor, enter
CPPCONN_PUBLIC_FUNC=into the 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 Connector/C++ dynamically linked library, carry out these steps:
Under Linker, Input, add
mysqlcppconn.libinto the Additional Dependencies text field.
mysqlcppconn.dllmust be in the same directory as the application executable, or somewhere on the system's path, so that the application can access the Connector/C++ Dynamic Linked Library at runtime.
mysqlcppconn.dllto the same directory as the application. Alternatively, extend the
PATHenvironment variable using
SET PATH=%PATH%;C:\path\to\cpp. Alternatively, you can copy
mysqlcppconn.dllto the Windows installation Directory, typically
