This section refers to dynamic linking of Connector/C++ to the client library, not dynamic linking of applications to Connector/C++. Precompiled binaries of Connector/C++ use static binding with the client library by default.
An application that uses Connector/C++ can be linked either statically or dynamically to the Connector/C++ libraries. Connector/C++ is usually linked statically to the underlying MySQL client library.
It is also possible to link dynamically to the underlying MySQL
client library, although this capability is not enabled by
default. To link Connector/C++ dynamically to the client library, disable
building Connector/C++ from source:
rm CMakeCache.txt cmake . -DMYSQLCLIENT_STATIC_LINKING=0 make clean make make install
Now, when creating a connection in your application, Connector/C++ selects and loads a client library at runtime. It chooses the client library by searching defined locations and environment variables depending on the host operating system. It is also possible when creating a connection in an application to define an absolute path to the client library to load at runtime. This can be convenient if you have defined a standard location from which you want the client library to be loaded. This is sometimes done to circumvent possible conflicts with other versions of the client library that may be located on the system.
disabled to enable dynamic linking to the MySQL client library,
determines whether to link to the shared MySQL client library. By
is enabled. If
disabled, Connector/C++ is not linked to the shared MySQL client library.
Instead, that library is loaded and mapped at runtime.
