MySQL Embedded - Getting started with libmysqld. In the Embedded subdirectory, both debug and release versions are available, and in DLL and static builds.

Note The libmysqld embedded server library is deprecated as of MySQL 5.7.19 and will be removed in MySQL 8.0. Both libraries have the same interface.

In terms of C API calls, an application communicates with a standalone server the same way it communicates with an embedded server. A given client can be built to communicate with a standalone or embedded server, depending on whether it is linked against libmysqlclient or libmysqld at build time. There are two ways to obtain the C API header and library files required to build C API client programs. • Install a MySQL Server distribution. Server distributions include both libmysqlclient and libmysqld. • Install a Connector/C distribution. Connector/C distributions include only libmysqlclient.

They do not include libmysqld. For both MySQL Server and Connector/C, you can install a binary distribution that contains the C API files pre-built, or you can use a source distribution and build the C API files yourself. Normally, you install either a MySQL Server distribution or a Connector/C distribution, but not both. For information about issues involved with simultaneous MySQL Server and Connector/C installations, see. The names of the library files to use when linking C API client applications depend on the library type and platform for which a distribution is built.

• On Unix (and Unix-like) systems, the static library is libmysqlclient.a. The dynamic library is libmysqlclient.so on most Unix systems and libmysqlclient.dylib on OS X. For distributions that include embedded server libraries, the corresponding library names begin with libmysqld rather than libmysqlclient. • On Windows, the static library is mysqlclient.lib and the dynamic library is libmysql.dll. Windows distributions also include libmysql.lib, a static import library needed for using the dynamic library.

For distributions that include embedded server libraries, the corresponding library names are mysqlserver.lib, libmysqld.dll, and libmysqld.lib. Windows distributions also include a set of debug libraries. These have the same names as the nondebug libraries, but are located in the lib/debug library. You must use the debug libraries when compiling clients built using the debug C runtime. On Unix, you may also see libraries that include _r in the names. Before MySQL 5.5, these were built as thread-safe (re-entrant) libraries separately from the non- _r libraries. As of 5.5, both libraries are the same and the _r names are symbolic links to the corresponding non- _r names.

There is no need to use the _r libraries. For example, if you use to obtain linker flags, you can use in all cases, even for threaded clients. There is no need to use.
