Building MySQL from Source  /  MySQL Source-Configuration Options

Chapter 4 MySQL Source-Configuration Options

The CMake program provides a great deal of control over how you configure a MySQL source distribution. Typically, you do this using options on the CMake command line. For information about options supported by CMake, run either of these commands in the top-level source directory: 

$> cmake . -LH
$> ccmake .

You can also affect CMake using certain environment variables. See Environment Variables.

For boolean options, the value may be specified as 1 or ON to enable the option, or as 0 or OFF to disable the option.

Many options configure compile-time defaults that can be overridden at server startup. For example, the CMAKE_INSTALL_PREFIX, MYSQL_TCP_PORT, and MYSQL_UNIX_ADDR options that configure the default installation base directory location, TCP/IP port number, and Unix socket file can be changed at server startup with the --basedir, --port, and --socket options for mysqld. Where applicable, configuration option descriptions indicate the corresponding mysqld startup option.

The following sections provide more information about CMake options.

CMake Option Reference

The following table shows the available CMake options. In the Default column, PREFIX stands for the value of the CMAKE_INSTALL_PREFIX option, which specifies the installation base directory. This value is used as the parent location for several of the installation subdirectories.

General Options

  • -DBUILD_CONFIG=mysql_release

    This option configures a source distribution with the same build options used by Oracle to produce binary distributions for official MySQL releases.

  • -DWITH_BUILD_ID=bool

    On Linux systems, generates a unique build ID which is used as the value of the build_id system variable and written to the MySQL server log on startup. Set this option to OFF to disable this feature.

    Added in MySQL 8.0.31, this option has no effect on platforms other than Linux.

  • -DBUNDLE_RUNTIME_LIBRARIES=bool

    Whether to bundle runtime libraries with server MSI and Zip packages for Windows.

  • -DCMAKE_BUILD_TYPE=type

    The type of build to produce:

    • RelWithDebInfo: Enable optimizations and generate debugging information. This is the default MySQL build type.

    • Release: Enable optimizations but omit debugging information to reduce the build size. This build type was added in MySQL 8.0.13.

    • Debug: Disable optimizations and generate debugging information. This build type is also used if the WITH_DEBUG option is enabled. That is, -DWITH_DEBUG=1 has the same effect as -DCMAKE_BUILD_TYPE=Debug.

    The option values None and MinSizeRel are not supported.

  • -DCPACK_MONOLITHIC_INSTALL=bool

    This option affects whether the make package operation produces multiple installation package files or a single file. If disabled, the operation produces multiple installation package files, which may be useful if you want to install only a subset of a full MySQL installation. If enabled, it produces a single file for installing everything.

  • -DFORCE_INSOURCE_BUILD=bool

    Defines whether to force an in-source build. Out-of-source builds are recommended, as they permit multiple builds from the same source, and cleanup can be performed quickly by removing the build directory. To force an in-source build, invoke CMake with -DFORCE_INSOURCE_BUILD=ON.

  • -DFORCE_COLORED_OUTPUT=bool

    Defines whether to enable colorized compiler output for gcc and clang when compiling on the command line. Defaults to OFF.

Installation Layout Options

The CMAKE_INSTALL_PREFIX option indicates the base installation directory. Other options with names of the form INSTALL_xxx that indicate component locations are interpreted relative to the prefix and their values are relative pathnames. Their values should not include the prefix.

Storage Engine Options

Storage engines are built as plugins. You can build a plugin as a static module (compiled into the server) or a dynamic module (built as a dynamic library that must be installed into the server using the INSTALL PLUGIN statement or the --plugin-load option before it can be used). Some plugins might not support static or dynamic building.

The InnoDB, MyISAM, MERGE, MEMORY, and CSV engines are mandatory (always compiled into the server) and need not be installed explicitly.

To compile a storage engine statically into the server, use -DWITH_engine_STORAGE_ENGINE=1. Some permissible engine values are ARCHIVE, BLACKHOLE, EXAMPLE, and FEDERATED. Examples: 

-DWITH_ARCHIVE_STORAGE_ENGINE=1
-DWITH_BLACKHOLE_STORAGE_ENGINE=1

To build MySQL with support for NDB Cluster, use the WITH_NDB option. (NDB 8.0.30 and earlier: Use WITH_NDBCLUSTER.)

Note

It is not possible to compile without Performance Schema support. If it is desired to compile without particular types of instrumentation, that can be done with the following CMake options: 

DISABLE_PSI_COND
DISABLE_PSI_DATA_LOCK
DISABLE_PSI_ERROR
DISABLE_PSI_FILE
DISABLE_PSI_IDLE
DISABLE_PSI_MEMORY
DISABLE_PSI_METADATA
DISABLE_PSI_MUTEX
DISABLE_PSI_PS
DISABLE_PSI_RWLOCK
DISABLE_PSI_SOCKET
DISABLE_PSI_SP
DISABLE_PSI_STAGE
DISABLE_PSI_STATEMENT
DISABLE_PSI_STATEMENT_DIGEST
DISABLE_PSI_TABLE
DISABLE_PSI_THREAD
DISABLE_PSI_TRANSACTION

For example, to compile without mutex instrumentation, configure MySQL using -DDISABLE_PSI_MUTEX=1.

To exclude a storage engine from the build, use -DWITH_engine_STORAGE_ENGINE=0. Examples: 

-DWITH_ARCHIVE_STORAGE_ENGINE=0
-DWITH_EXAMPLE_STORAGE_ENGINE=0
-DWITH_FEDERATED_STORAGE_ENGINE=0

It is also possible to exclude a storage engine from the build using -DWITHOUT_engine_STORAGE_ENGINE=1 (but -DWITH_engine_STORAGE_ENGINE=0 is preferred). Examples: 

-DWITHOUT_ARCHIVE_STORAGE_ENGINE=1
-DWITHOUT_EXAMPLE_STORAGE_ENGINE=1
-DWITHOUT_FEDERATED_STORAGE_ENGINE=1

If neither -DWITH_engine_STORAGE_ENGINE nor -DWITHOUT_engine_STORAGE_ENGINE are specified for a given storage engine, the engine is built as a shared module, or excluded if it cannot be built as a shared module.

Feature Options

  • -DADD_GDB_INDEX=bool

    This option determines whether to enable generation of a .gdb_index section in binaries, which makes loading them in a debugger faster. The option is disabled by default. lld linker is used, and is disabled by It has no effect if a linker other than lld or GNU gold is used.

    This option was added in MySQL 8.0.18.

  • -DCOMPILATION_COMMENT=string

    A descriptive comment about the compilation environment. As of MySQL 8.0.14, mysqld uses COMPILATION_COMMENT_SERVER. Other programs continue to use COMPILATION_COMMENT.

  • -DCOMPRESS_DEBUG_SECTIONS=bool

    Whether to compress the debug sections of binary executables (Linux only). Compressing executable debug sections saves space at the cost of extra CPU time during the build process.

    The default is OFF. If this option is not set explicitly but the COMPRESS_DEBUG_SECTIONS environment variable is set, the option takes its value from that variable.

    This option was added in MySQL 8.0.22.

  • -DCOMPILATION_COMMENT_SERVER=string

    A descriptive comment about the compilation environment for use by mysqld (for example, to set the version_comment system variable). This option was added in MySQL 8.0.14. Prior to 8.0.14, the server uses COMPILATION_COMMENT.

  • -DDEFAULT_CHARSET=charset_name

    The server character set. By default, MySQL uses the utf8mb4 character set.

    charset_name may be one of binary, armscii8, ascii, big5, cp1250, cp1251, cp1256, cp1257, cp850, cp852, cp866, cp932, dec8, eucjpms, euckr, gb2312, gbk, geostd8, greek, hebrew, hp8, keybcs2, koi8r, koi8u, latin1, latin2, latin5, latin7, macce, macroman, sjis, swe7, tis620, ucs2, ujis, utf8mb3, utf8mb4, utf16, utf16le, utf32.

    This value can be set at server startup with the --character-set-server option.

  • -DDEFAULT_COLLATION=collation_name

    The server collation. By default, MySQL uses utf8mb4_0900_ai_ci. Use the SHOW COLLATION statement to determine which collations are available for each character set.

    This value can be set at server startup with the --collation_server option.

  • -DDISABLE_PSI_COND=bool

    Whether to exclude the Performance Schema condition instrumentation. The default is OFF (include).

  • -DDISABLE_PSI_FILE=bool

    Whether to exclude the Performance Schema file instrumentation. The default is OFF (include).

  • -DDISABLE_PSI_IDLE=bool

    Whether to exclude the Performance Schema idle instrumentation. The default is OFF (include).

  • -DDISABLE_PSI_MEMORY=bool

    Whether to exclude the Performance Schema memory instrumentation. The default is OFF (include).

  • -DDISABLE_PSI_METADATA=bool

    Whether to exclude the Performance Schema metadata instrumentation. The default is OFF (include).

  • -DDISABLE_PSI_MUTEX=bool

    Whether to exclude the Performance Schema mutex instrumentation. The default is OFF (include).

  • -DDISABLE_PSI_RWLOCK=bool

    Whether to exclude the Performance Schema rwlock instrumentation. The default is OFF (include).

  • -DDISABLE_PSI_SOCKET=bool

    Whether to exclude the Performance Schema socket instrumentation. The default is OFF (include).

  • -DDISABLE_PSI_SP=bool

    Whether to exclude the Performance Schema stored program instrumentation. The default is OFF (include).

  • -DDISABLE_PSI_STAGE=bool

    Whether to exclude the Performance Schema stage instrumentation. The default is OFF (include).

  • -DDISABLE_PSI_STATEMENT=bool

    Whether to exclude the Performance Schema statement instrumentation. The default is OFF (include).

  • -DDISABLE_PSI_STATEMENT_DIGEST=bool

    Whether to exclude the Performance Schema statement digest instrumentation. The default is OFF (include).

  • -DDISABLE_PSI_TABLE=bool

    Whether to exclude the Performance Schema table instrumentation. The default is OFF (include).

  • -DDISABLE_SHARED=bool

    Whether to disable building build shared libraries and compile position-dependent code. The default is OFF (compile position-independent code).

    This option is unused, and was removed in MySQL 8.0.18.

  • -DDISABLE_PSI_PS=bool

    Exclude the Performance Schema prepared statements instances instrumentation. The default is OFF (include).

  • -DDISABLE_PSI_THREAD=bool

    Exclude the Performance Schema thread instrumentation. The default is OFF (include).

    Only disable threads when building without any instrumentation, because other instrumentations have a dependency on threads.

  • -DDISABLE_PSI_TRANSACTION=bool

    Exclude the Performance Schema transaction instrumentation. The default is OFF (include).

  • -DDISABLE_PSI_DATA_LOCK=bool

    Exclude the performance schema data lock instrumentation. The default is OFF (include).

  • -DDISABLE_PSI_ERROR=bool

    Exclude the performance schema server error instrumentation. The default is OFF (include).

  • -DDOWNLOAD_BOOST=bool

    Whether to download the Boost library. The default is OFF.

    See the WITH_BOOST option for additional discussion about using Boost.

  • -DDOWNLOAD_BOOST_TIMEOUT=seconds

    The timeout in seconds for downloading the Boost library. The default is 600 seconds.

    See the WITH_BOOST option for additional discussion about using Boost.

  • -DENABLE_DOWNLOADS=bool

    Whether to download optional files. For example, with this option enabled, CMake downloads the Google Test distribution that is used by the test suite to run unit tests, or Ant and JUnit, required for building the GCS Java wrapper.

    As of MySQL 8.0.26, MySQL source distributions bundle the Google Test source code used to run unit tests. Consequently, as of that version the WITH_GMOCK and ENABLE_DOWNLOADS CMake options are removed and are ignored if specified.

  • -DENABLE_EXPERIMENTAL_SYSVARS=bool

    Whether to enable experimental InnoDB system variables. Experimental system variables are intended for those engaged in MySQL development, should only be used in a development or test environment, and may be removed without notice in a future MySQL release. For information about experimental system variables, refer to /storage/innobase/handler/ha_innodb.cc in the MySQL source tree. Experimental system variables can be identified by searching for “PLUGIN_VAR_EXPERIMENTAL”.

  • -DENABLE_GCOV=bool

    Whether to include gcov support (Linux only).

  • -DENABLE_GPROF=bool

    Whether to enable gprof (optimized Linux builds only).

  • -DENABLED_LOCAL_INFILE=bool

    This option controls the compiled-in default LOCAL capability for the MySQL client library. Clients that make no explicit arrangements therefore have LOCAL capability disabled or enabled according to the ENABLED_LOCAL_INFILE setting specified at MySQL build time.

    By default, the client library in MySQL binary distributions is compiled with ENABLED_LOCAL_INFILE disabled. If you compile MySQL from source, configure it with ENABLED_LOCAL_INFILE disabled or enabled based on whether clients that make no explicit arrangements should have LOCAL capability disabled or enabled, respectively.

    ENABLED_LOCAL_INFILE controls the default for client-side LOCAL capability. For the server, the local_infile system variable controls server-side LOCAL capability. To explicitly cause the server to refuse or permit LOAD DATA LOCAL statements (regardless of how client programs and libraries are configured at build time or runtime), start mysqld with --local-infile disabled or enabled, respectively. local_infile can also be set at runtime. See Security Considerations for LOAD DATA LOCAL.

  • -DENABLED_PROFILING=bool

    Whether to enable query profiling code (for the SHOW PROFILE and SHOW PROFILES statements).

  • -DFORCE_UNSUPPORTED_COMPILER=bool

    By default, CMake checks for minimum versions of supported compilers; to disable this check, use -DFORCE_UNSUPPORTED_COMPILER=ON.

  • -DFPROFILE_GENERATE=bool

    Whether to generate profile guided optimization (PGO) data. This option is available for experimenting with PGO with GCC. See cmake/fprofile.cmake in the MySQL source distribution for information about using FPROFILE_GENERATE and FPROFILE_USE. These options have been tested with GCC 8 and 9.

    This option was added in MySQL 8.0.19.

  • -DFPROFILE_USE=bool

    Whether to use profile guided optimization (PGO) data. This option is available for experimenting with PGO with GCC. See the cmake/fprofile.cmake file in a MySQL source distribution for information about using FPROFILE_GENERATE and FPROFILE_USE. These options have been tested with GCC 8 and 9.

    Enabling FPROFILE_USE also enables WITH_LTO.

    This option was added in MySQL 8.0.19.

  • -DHAVE_PSI_MEMORY_INTERFACE=bool

    Whether to enable the performance schema memory tracing module for memory allocation functions (ut::aligned_name library functions) used in dynamic storage of over-aligned types.

  • -DIGNORE_AIO_CHECK=bool

    If the -DBUILD_CONFIG=mysql_release option is given on Linux, the libaio library must be linked in by default. If you do not have libaio or do not want to install it, you can suppress the check for it by specifying -DIGNORE_AIO_CHECK=1.

  • -DMAX_INDEXES=num

    The maximum number of indexes per table. The default is 64. The maximum is 255. Values smaller than 64 are ignored and the default of 64 is used.

  • -DMYSQL_MAINTAINER_MODE=bool

    Whether to enable a MySQL maintainer-specific development environment. If enabled, this option causes compiler warnings to become errors.

  • -DWITH_DEVELOPER_ENTITLEMENTS=bool

    Whether to add the get-task-allow entitlement to all executables to generate a core dump in the event of an unexpected server halt.

    On macOS 11+, core dumps are limited to processes with the com.apple.security.get-task-allow entitlement, which this CMake option enables. The entitlement allows other processes to attach and read/modify the processes memory, and allows --core-file to function as expected.

    This option was added in MySQL 8.0.30.

  • -DMUTEX_TYPE=type

    The mutex type used by InnoDB. Options include:

    • event: Use event mutexes. This is the default value and the original InnoDB mutex implementation.

    • sys: Use POSIX mutexes on UNIX systems. Use CRITICAL_SECTION objects on Windows, if available.

    • futex: Use Linux futexes instead of condition variables to schedule waiting threads.

  • -DMYSQLX_TCP_PORT=port_num

    The port number on which X Plugin listens for TCP/IP connections. The default is 33060.

    This value can be set at server startup with the mysqlx_port system variable.

  • -DMYSQLX_UNIX_ADDR=file_name

    The Unix socket file path on which the server listens for X Plugin socket connections. This must be an absolute path name. The default is /tmp/mysqlx.sock.

    This value can be set at server startup with the mysqlx_port system variable.

  • -DMYSQL_PROJECT_NAME=name

    For Windows or macOS, the project name to incorporate into the project file name.

  • -DMYSQL_TCP_PORT=port_num

    The port number on which the server listens for TCP/IP connections. The default is 3306.

    This value can be set at server startup with the --port option.

  • -DMYSQL_UNIX_ADDR=file_name

    The Unix socket file path on which the server listens for socket connections. This must be an absolute path name. The default is /tmp/mysql.sock.

    This value can be set at server startup with the --socket option.

  • -DOPTIMIZER_TRACE=bool

    Whether to support optimizer tracing. See Tracing the Optimizer.

  • -DREPRODUCIBLE_BUILD=bool

    For builds on Linux systems, this option controls whether to take extra care to create a build result independent of build location and time.

    This option was added in MySQL 8.0.11. As of MySQL 8.0.12, it defaults to ON for RelWithDebInfo builds.

  • -DSHOW_SUPPRESSED_COMPILER_WARNINGS=bool

    Show suppressed compiler warnings, and do so without failing with -Werror. Defaults to OFF.

    This option was added in MySQL 8.0.30.

  • -DUSE_LD_GOLD=bool

    GNU gold linker support was removed in MySQL 8.0.31; this CMake option was also removed.

    CMake causes the build process to link with the GNU gold linker if it is available and not explicitly disabled. To disable use of this linker, specify the -DUSE_LD_GOLD=OFF option.

  • -DUSE_LD_LLD=bool

    CMake causes the build process to link using the LLVM lld linker for Clang if it is available and not explicitly disabled. To disable use of this linker, specify the -DUSE_LD_LLD=OFF option.

    This option was added in MySQL 8.0.16.

  • -DWIN_DEBUG_NO_INLINE=bool

    Whether to disable function inlining on Windows. The default is OFF (inlining enabled).

  • -DWITH_ANT=path_name

    Set the path to Ant, required when building GCS Java wrapper. Set WITH_ANT to the path of a directory where the Ant tarball or unpacked archive is saved. When WITH_ANT is not set, or is set with the special value system, the build process assumes a binary ant exists in $PATH.

  • -DWITH_ASAN=bool

    Whether to enable the AddressSanitizer, for compilers that support it. The default is OFF.

  • -DWITH_ASAN_SCOPE=bool

    Whether to enable the AddressSanitizer -fsanitize-address-use-after-scope Clang flag for use-after-scope detection. The default is off. To use this option, -DWITH_ASAN must also be enabled.

  • -DWITH_AUTHENTICATION_CLIENT_PLUGINS=bool

    This option is enabled automatically if any corresponding server authentication plugins are built. Its value thus depends on other CMake options and it should not be set explicitly.

    This option was added in MySQL 8.0.26.

  • -DWITH_AUTHENTICATION_LDAP=bool

    Whether to report an error if the LDAP authentication plugins cannot be built:

    • If this option is disabled (the default), the LDAP plugins are built if the required header files and libraries are found. If they are not, CMake displays a note about it.

    • If this option is enabled, a failure to find the required header file and libraries causes CMake to produce an error, preventing the server from being built.

    For information about LDAP authentication, see LDAP Pluggable Authentication.

  • -DWITH_AUTHENTICATION_PAM=bool

    Whether to build the PAM authentication plugin, for source trees that include this plugin. (See PAM Pluggable Authentication.) If this option is specified and the plugin cannot be compiled, the build fails.

  • -DWITH_AWS_SDK=path_name

    The location of the Amazon Web Services software development kit.

  • -DWITH_BOOST=path_name

    The Boost library is required to build MySQL. These CMake options enable control over the library source location, and whether to download it automatically:

    • -DWITH_BOOST=path_name specifies the Boost library directory location. It is also possible to specify the Boost location by setting the BOOST_ROOT or WITH_BOOST environment variable.

      -DWITH_BOOST=system is also permitted and indicates that the correct version of Boost is installed on the compilation host in the standard location. In this case, the installed version of Boost is used rather than any version included with a MySQL source distribution.

    • -DDOWNLOAD_BOOST=bool specifies whether to download the Boost source if it is not present in the specified location. The default is OFF.

    • -DDOWNLOAD_BOOST_TIMEOUT=seconds the timeout in seconds for downloading the Boost library. The default is 600 seconds.

    For example, if you normally build MySQL placing the object output in the bld subdirectory of your MySQL source tree, you can build with Boost like this: 

    mkdir bld
cd bld
cmake .. -DDOWNLOAD_BOOST=ON -DWITH_BOOST=$HOME/my_boost

    This causes Boost to be downloaded into the my_boost directory under your home directory. If the required Boost version is already there, no download is done. If the required Boost version changes, the newer version is downloaded.

    If Boost is already installed locally and your compiler finds the Boost header files on its own, it may not be necessary to specify the preceding CMake options. However, if the version of Boost required by MySQL changes and the locally installed version has not been upgraded, you may have build problems. Using the CMake options should give you a successful build.

    With the above settings that allow Boost download into a specified location, when the required Boost version changes, you need to remove the bld folder, recreate it, and perform the cmake step again. Otherwise, the new Boost version might not get downloaded, and compilation might fail.

  • -DWITH_CLIENT_PROTOCOL_TRACING=bool

    Whether to build the client-side protocol tracing framework into the client library. By default, this option is enabled.

    For information about writing protocol trace client plugins, see Writing Protocol Trace Plugins.

    See also the WITH_TEST_TRACE_PLUGIN option.

  • -DWITH_CURL=curl_type

    The location of the curl library. curl_type can be system (use the system curl library) or a path name to the curl library.

  • -DWITH_DEBUG=bool

    Whether to include debugging support.

    Configuring MySQL with debugging support enables you to use the --debug="d,parser_debug" option when you start the server. This causes the Bison parser that is used to process SQL statements to dump a parser trace to the server's standard error output. Typically, this output is written to the error log.

    Sync debug checking for the InnoDB storage engine is defined under UNIV_DEBUG and is available when debugging support is compiled in using the WITH_DEBUG option. When debugging support is compiled in, the innodb_sync_debug configuration option can be used to enable or disable InnoDB sync debug checking.

    Enabling WITH_DEBUG also enables Debug Sync. This facility is used for testing and debugging. When compiled in, Debug Sync is disabled by default at runtime. To enable it, start mysqld with the --debug-sync-timeout=N option, where N is a timeout value greater than 0. (The default value is 0, which disables Debug Sync.) N becomes the default timeout for individual synchronization points.

    Sync debug checking for the InnoDB storage engine is available when debugging support is compiled in using the WITH_DEBUG option.

    For a description of the Debug Sync facility and how to use synchronization points, see MySQL Internals: Test Synchronization.

  • -DWITH_DEFAULT_FEATURE_SET=bool

    Whether to use the flags from cmake/build_configurations/feature_set.cmake. This option was removed in MySQL 8.0.22.

  • -DWITH_EDITLINE=value

    Which libedit/editline library to use. The permitted values are bundled (the default) and system.

  • -DWITH_FIDO=fido_type

    The authentication_fido authentication plugin is implemented using a FIDO library (see FIDO Pluggable Authentication). The WITH_FIDO option indicates the source of FIDO support:

    • bundled: Use the FIDO library bundled with the distribution. This is the default.

      As of MySQL 8.0.30, MySQL includes fido2 version 1.8.0. (Prior releases used fido2 1.5.0).

    • system: Use the system FIDO library.

    WITH_FIDO is disabled (set to none) if all authentication plugins are disabled.

    This option was added in MySQL 8.0.27.

  • -DWITH_GMOCK=path_name

    The path to the googlemock distribution, for use with Google Test-based unit tests. The option value is the path to the distribution zip file. Alternatively, set the WITH_GMOCK environment variable to the path name. It is also possible to use -DENABLE_DOWNLOADS=1, so that CMake downloads the distribution from GitHub.

    If you build MySQL without the Google Test unit tests (by configuring without WITH_GMOCK), CMake displays a message indicating how to download it.

    As of MySQL 8.0.26, MySQL source distributions bundle the Google Test source code. Consequently, as of that version, the WITH_GMOCK and ENABLE_DOWNLOADS CMake options are removed and are ignored if specified.

  • -DWITH_ICU={icu_type|path_name}

    MySQL uses International Components for Unicode (ICU) to support regular expression operations. The WITH_ICU option indicates the type of ICU support to include or the path name to the ICU installation to use.

    • icu_type can be one of the following values:

      • bundled: Use the ICU library bundled with the distribution. This is the default, and is the only supported option for Windows.

      • system: Use the system ICU library.

    • path_name is the path name to the ICU installation to use. This can be preferable to using the icu_type value of system because it can prevent CMake from detecting and using an older or incorrect ICU version installed on the system. (Another permitted way to do the same thing is to set WITH_ICU to system and set the CMAKE_PREFIX_PATH option to path_name.)

  • -DWITH_INNODB_EXTRA_DEBUG=bool

    Whether to include extra InnoDB debugging support.

    Enabling WITH_INNODB_EXTRA_DEBUG turns on extra InnoDB debug checks. This option can only be enabled when WITH_DEBUG is enabled.

  • -DWITH_INNODB_MEMCACHED=bool

    Whether to generate memcached shared libraries (libmemcached.so and innodb_engine.so).

  • -DWITH_JEMALLOC=bool

    Whether to link with -ljemalloc. If enabled, built-in malloc(), calloc(), realloc(), and free() routines are disabled. The default is OFF.

    WITH_JEMALLOC and WITH_TCMALLOC are mutually exclusive.

    This option was added in MySQL 8.0.16.

  • -DWITH_KEYRING_TEST=bool

    Whether to build the test program that accompanies the keyring_file plugin. The default is OFF. Test file source code is located in the plugin/keyring/keyring-test directory.

  • -DWITH_LIBEVENT=string

    Which libevent library to use. Permitted values are bundled (default) and system. Prior to MySQL 8.0.21, if you specify system, the system libevent library is used if present, and an error occurs otherwise. In MySQL 8.0.21 and later, if system is specified and no system libevent library can be found, an error occurs regardless, and the bundled libevent is not used.

    The libevent library is required by InnoDB memcached, X Plugin, and MySQL Router.

  • -DWITH_LIBWRAP=bool

    Whether to include libwrap (TCP wrappers) support.

  • -DWITH_LOCK_ORDER=bool

    Whether to enable LOCK_ORDER tooling. By default, this option is disabled and server builds contain no tooling. If tooling is enabled, the LOCK_ORDER tool is available and can be used as described in The LOCK_ORDER Tool.

    Note

    With the WITH_LOCK_ORDER option enabled, MySQL builds require the flex program.

    This option was added in MySQL 8.0.17.

  • -DWITH_LSAN=bool

    Whether to run LeakSanitizer, without AddressSanitizer. The default is OFF.

    This option was added in MySQL 8.0.16.

  • -DWITH_LTO=bool

    Whether to enable the link-time optimizer, if the compiler supports it. The default is OFF unless FPROFILE_USE is enabled.

    This option was added in MySQL 8.0.13.

  • -DWITH_LZ4=lz4_type

    The WITH_LZ4 option indicates the source of zlib support:

    • bundled: Use the lz4 library bundled with the distribution. This is the default.

    • system: Use the system lz4 library. If WITH_LZ4 is set to this value, the lz4_decompress utility is not built. In this case, the system lz4 command can be used instead.

  • -DWITH_LZMA=lzma_type

    The type of LZMA library support to include. lzma_type can be one of the following values:

    • bundled: Use the LZMA library bundled with the distribution. This is the default.

    • system: Use the system LZMA library.

    This option was removed in MySQL 8.0.16.

  • -DWITH_MECAB={disabled|system|path_name}

    Use this option to compile the MeCab parser. If you have installed MeCab to its default installation directory, set -DWITH_MECAB=system. The system option applies to MeCab installations performed from source or from binaries using a native package management utility. If you installed MeCab to a custom installation directory, specify the path to the MeCab installation, for example, -DWITH_MECAB=/opt/mecab. If the system option does not work, specifying the MeCab installation path should work in all cases.

    For related information, see MeCab Full-Text Parser Plugin.

  • -DWITH_MSAN=bool

    Whether to enable MemorySanitizer, for compilers that support it. The default is off.

    For this option to have an effect if enabled, all libraries linked to MySQL must also have been compiled with the option enabled.

  • -DWITH_MSCRT_DEBUG=bool

    Whether to enable Visual Studio CRT memory leak tracing. The default is OFF.

  • -DMSVC_CPPCHECK=bool

    Whether to enable MSVC code analysis. The default is OFF.

  • -DWITH_MYSQLX=bool

    Whether to build with support for X Plugin. The default is ON. See Using MySQL as a Document Store.

  • -DWITH_NUMA=bool

    Explicitly set the NUMA memory allocation policy. CMake sets the default WITH_NUMA value based on whether the current platform has NUMA support. For platforms without NUMA support, CMake behaves as follows:

    • With no NUMA option (the normal case), CMake continues normally, producing only this warning: NUMA library missing or required version not available.

    • With -DWITH_NUMA=ON, CMake aborts with this error: NUMA library missing or required version not available.

  • -DWITH_PACKAGE_FLAGS=bool

    For flags typically used for RPM and Debian packages, whether to add them to standalone builds on those platforms. The default is ON for nondebug builds.

    This option was added in MySQL 8.0.26.

  • -DWITH_PROTOBUF=protobuf_type

    Which Protocol Buffers package to use. protobuf_type can be one of the following values:

    • bundled: Use the package bundled with the distribution. This is the default. Optionally use INSTALL_PRIV_LIBDIR to modify the dynamic Protobuf library directory.

    • system: Use the package installed on the system.

    Other values are ignored, with a fallback to bundled.

  • -DWITH_RAPID=bool

    Whether to build the rapid development cycle plugins. When enabled, a rapid directory is created in the build tree containing these plugins. When disabled, no rapid directory is created in the build tree. The default is ON, unless the rapid directory is removed from the source tree, in which case the default becomes OFF.

  • -DWITH_RAPIDJSON=rapidjson_type

    The type of RapidJSON library support to include. rapidjson_type can be one of the following values:

    • bundled: Use the RapidJSON library bundled with the distribution. This is the default.

    • system: Use the system RapidJSON library. Version 1.1.0 or later is required.

    This option was added in MySQL 8.0.13.

  • -DWITH_RE2=re2_type

    The type of RE2 library support to include. re2_type can be one of the following values:

    • bundled: Use the RE2 library bundled with the distribution. This is the default.

    • system: Use the system RE2 library.

    As of MySQL 8.0.18, MySQL no longer uses the RE2 library, and this option has been removed.

  • -DWITH_ROUTER=bool

    Whether to build MySQL Router. The default is ON.

    This option was added in MySQL 8.0.16.

  • -DWITH_SASL=value

    Internal use only. This option was added in 8.0.20. Not supported on Windows.

  • -DWITH_SSL={ssl_type|path_name}

    For support of encrypted connections, entropy for random number generation, and other encryption-related operations, MySQL must be built using an SSL library. This option specifies which SSL library to use.

    • ssl_type can be one of the following values:

      • system: Use the system OpenSSL library. This is the default.

        On macOS and Windows, using system configures MySQL to build as if CMake was invoked with path_name points to a manually installed OpenSSL library. This is because they do not have system SSL libraries. On macOS, brew install openssl installs to /usr/local/opt/openssl so that system can find it. On Windows, it checks %ProgramFiles%/OpenSSL, %ProgramFiles%/OpenSSL-Win32, %ProgramFiles%/OpenSSL-Win64, C:/OpenSSL, C:/OpenSSL-Win32, and C:/OpenSSL-Win64.

      • yes: This is a synonym for system.

      • opensslversion: (MySQL 8.0.30 and later:) Use an alternate OpenSSL system package such as openssl11 on EL7, or openssl3 on EL8.

        Authentication plugins, such as LDAP and Kerberos, are disabled as they do not support these alternative versions of OpenSSL.

    • path_name is the path name to the OpenSSL installation to use. This can be preferable to using the ssl_type value of system because it can prevent CMake from detecting and using an older or incorrect OpenSSL version installed on the system. (Another permitted way to do the same thing is to set WITH_SSL to system and set the CMAKE_PREFIX_PATH option to path_name.)

    For additional information about configuring the SSL library, see Configuring SSL Library Support.

  • -DWITH_SYSTEMD=bool

    Whether to enable installation of systemd support files. By default, this option is disabled. When enabled, systemd support files are installed, and scripts such as mysqld_safe and the System V initialization script are not installed. On platforms where systemd is not available, enabling WITH_SYSTEMD results in an error from CMake.

    For more information about using systemd, see Managing MySQL Server with systemd. That section also includes information about specifying options otherwise specified in [mysqld_safe] option groups. Because mysqld_safe is not installed when systemd is used, such options must be specified another way.

  • -DWITH_SYSTEM_LIBS=bool

    This option serves as an “umbrella” option to set the system value of any of the following CMake options that are not set explicitly: WITH_CURL, WITH_EDITLINE, WITH_FIDO, WITH_ICU, WITH_LIBEVENT, WITH_LZ4, WITH_LZMA, WITH_PROTOBUF, WITH_RE2, WITH_SSL, WITH_ZSTD.

    WITH_ZLIB was included here priot MySQL 8.0.30.

  • -DWITH_SYSTEMD_DEBUG=bool

    Whether to produce additional systemd debugging information, for platforms on which systemd is used to run MySQL. The default is OFF.

    This option was added in MySQL 8.0.22.

  • -DWITH_TCMALLOC=bool

    Whether to link with -ltcmalloc. If enabled, built-in malloc(), calloc(), realloc(), and free() routines are disabled. The default is OFF.

    Beginning with MySQL 8.0.38, a tcmalloc library is included in the source; you can cause the build to use the bundled version by setting this option to BUNDLED. BUNDLED is supported on Linux systems only.

    WITH_TCMALLOC and WITH_JEMALLOC are mutually exclusive.

    This option was added in MySQL 8.0.22.

  • -DWITH_TEST_TRACE_PLUGIN=bool

    Whether to build the test protocol trace client plugin (see Using the Test Protocol Trace Plugin). By default, this option is disabled. Enabling this option has no effect unless the WITH_CLIENT_PROTOCOL_TRACING option is enabled. If MySQL is configured with both options enabled, the libmysqlclient client library is built with the test protocol trace plugin built in, and all the standard MySQL clients load the plugin. However, even when the test plugin is enabled, it has no effect by default. Control over the plugin is afforded using environment variables; see Using the Test Protocol Trace Plugin.

    Note

    Do not enable the WITH_TEST_TRACE_PLUGIN option if you want to use your own protocol trace plugins because only one such plugin can be loaded at a time and an error occurs for attempts to load a second one. If you have already built MySQL with the test protocol trace plugin enabled to see how it works, you must rebuild MySQL without it before you can use your own plugins.

    For information about writing trace plugins, see Writing Protocol Trace Plugins.

  • -DWITH_TSAN=bool

    Whether to enable the ThreadSanitizer, for compilers that support it. The default is off.

  • -DWITH_UBSAN=bool

    Whether to enable the Undefined Behavior Sanitizer, for compilers that support it. The default is off.

  • -DWITH_UNIT_TESTS={ON|OFF}

    If enabled, compile MySQL with unit tests. The default is ON unless the server is not being compiled.

  • -DWITH_UNIXODBC=1

    Enables unixODBC support, for Connector/ODBC.

  • -DWITH_VALGRIND=bool

    Whether to compile in the Valgrind header files, which exposes the Valgrind API to MySQL code. The default is OFF.

    To generate a Valgrind-aware debug build, -DWITH_VALGRIND=1 normally is combined with -DWITH_DEBUG=1. See Building Debug Configurations.

  • -DWITH_WIN_JEMALLOC=string

    On Windows, pass in a path to a directory containing jemalloc.dll to enable jemalloc functionality. The build system copies jemalloc.dll to the same directory as mysqld.exe and/or mysqld-debug.exe and utilizes it for memory management operations. Standard memory functions are used if jemalloc.dll is not found or does not export the required functions. An INFORMATION level log message records whether or not jemalloc is found and used.

    This option is enabled for official MySQL binaries for Windows.

    This option was added in MySQL 8.0.29.

  • -DWITH_ZLIB=zlib_type

    Some features require that the server be built with compression library support, such as the COMPRESS() and UNCOMPRESS() functions, and compression of the client/server protocol. The WITH_ZLIB option indicates the source of zlib support:

    In MYSQL 8.0.32 and later, the minimum supported version of zlib is 1.2.13.

    • bundled: Use the zlib library bundled with the distribution. This is the default.

    • system: Use the system zlib library. If WITH_ZLIB is set to this value, the zlib_decompress utility is not built. In this case, the system openssl zlib command can be used instead.

  • -DWITH_ZSTD=zstd_type

    Connection compression using the zstd algorithm (see Connection Compression Control) requires that the server be built with zstd library support. The WITH_ZSTD option indicates the source of zstd support:

    • bundled: Use the zstd library bundled with the distribution. This is the default.

    • system: Use the system zstd library.

    This option was added in MySQL 8.0.18.

  • -DWITHOUT_SERVER=bool

    Whether to build without MySQL Server. The default is OFF, which does build the server.

    This is considered an experimental option; it is preferred to build with the server.

    This option also prevents building of the NDB storage engine or any NDB binaries including management and data node programs.

Compiler Flags

To specify your own C and C++ compiler flags, for flags that do not affect optimization, use the CMAKE_C_FLAGS and CMAKE_CXX_FLAGS CMake options.

When providing your own compiler flags, you might want to specify CMAKE_BUILD_TYPE as well.

For example, to create a 32-bit release build on a 64-bit Linux machine, do this: 

$> mkdir build
$> cd build
$> cmake .. -DCMAKE_C_FLAGS=-m32 \
  -DCMAKE_CXX_FLAGS=-m32 \
  -DCMAKE_BUILD_TYPE=RelWithDebInfo

If you set flags that affect optimization (-Onumber), you must set the CMAKE_C_FLAGS_build_type and/or CMAKE_CXX_FLAGS_build_type options, where build_type corresponds to the CMAKE_BUILD_TYPE value. To specify a different optimization for the default build type (RelWithDebInfo) set the CMAKE_C_FLAGS_RELWITHDEBINFO and CMAKE_CXX_FLAGS_RELWITHDEBINFO options. For example, to compile on Linux with -O3 and with debug symbols, do this: 

$> cmake .. -DCMAKE_C_FLAGS_RELWITHDEBINFO="-O3 -g" \
  -DCMAKE_CXX_FLAGS_RELWITHDEBINFO="-O3 -g"

CMake Options for Compiling NDB Cluster

To compile with support for NDB Cluster, you can use -DWITH_NDB, which causes the build to include the NDB storage engine and all NDB programs. This option is enabled by default. To prevent building of the NDB storage engine plugin, use -DWITH_NDBCLUSTER_STORAGE_ENGINE=OFF. Other aspects of the build can be controlled using the other options listed in this section.

The following options apply when building the MySQL sources with NDB Cluster support.

  • -DMEMCACHED_HOME=dir_name

    NDB support for memcached was removed in NDB 8.0.23; thus, this option is no longer supported for building NDB in this or later versions.

  • -DNDB_UTILS_LINK_DYNAMIC={ON|OFF}

    Controls whether NDB utilities such as ndb_drop_table are linked with ndbclient statically (OFF) or dynamically (ON); OFF (static linking) is the default. Normally static linking is used when building these to avoid problems with LD_LIBRARY_PATH, or when multiple versions of ndbclient are installed. This option is intended for creating Docker images and possibly other cases in which the target environment is subject to precise control and it is desirable to reduce image size.

    Added in NDB 8.0.22.

  • -DWITH_BUNDLED_LIBEVENT={ON|OFF}

    NDB support for memcached was removed in NDB 8.0.23; thus, this option is no longer supported for building NDB in this or later versions.

  • -DWITH_BUNDLED_MEMCACHED={ON|OFF}

    NDB support for memcached was removed in NDB 8.0.23; thus, this option is no longer supported for building NDB in this or later versions.

  • -DWITH_CLASSPATH=path

    Sets the classpath for building MySQL NDB Cluster Connector for Java. The default is empty. This option is ignored if -DWITH_NDB_JAVA=OFF is used.

  • -DWITH_ERROR_INSERT={ON|OFF}

    Enables error injection in the NDB kernel. For testing only; not intended for use in building production binaries. The default is OFF.

  • -DWITH_NDB={ON|OFF}

    Build MySQL NDB Cluster; build the NDB plugin and all NDB Cluster programs.

    Added in NDB 8.0.31.

  • -DWITH_NDBAPI_EXAMPLES={ON|OFF}

    Build NDB API example programs in storage/ndb/ndbapi-examples/. See NDB API Examples, for information about these.

  • -DWITH_NDBCLUSTER_STORAGE_ENGINE={ON|OFF}

    NDB 8.0.30 and earlier: For internal use only; may not always work as expected. To build with NDB support, use WITH_NDBCLUSTER instead.

    NDB 8.0.31 and later: Controls (only) whether the NDBCLUSTER storage engine is included in the build; WITH_NDB enables this option automatically, so it is recommended that you use WITH_NDB instead.

  • -DWITH_NDBCLUSTER={ON|OFF} (DEPRECATED)

    Build and link in support for the NDB storage engine in mysqld.

    This option is deprecated as of NDB 8.0.31, and subject to eventual removal; use WITH_NDB instead.

  • -DWITH_NDBMTD={ON|OFF}

    Build the multithreaded data node executable ndbmtd. The default is ON.

  • -DWITH_NDB_DEBUG={ON|OFF}

    Enable building the debug versions of the NDB Cluster binaries. This is OFF by default.

  • -DWITH_NDB_JAVA={ON|OFF}

    Enable building NDB Cluster with Java support, including support for ClusterJ (see MySQL NDB Cluster Connector for Java).

    This option is ON by default. If you do not wish to compile NDB Cluster with Java support, you must disable it explicitly by specifying -DWITH_NDB_JAVA=OFF when running CMake. Otherwise, if Java cannot be found, configuration of the build fails.

  • -DWITH_NDB_PORT=port

    Causes the NDB Cluster management server (ndb_mgmd) that is built to use this port by default. If this option is unset, the resulting management server tries to use port 1186 by default.

  • -DWITH_NDB_TEST={ON|OFF}

    If enabled, include a set of NDB API test programs. The default is OFF.

  • -DWITH_PLUGIN_NDBCLUSTER={ON|OFF}

    For internal use only; may not always work as expected. This option was removed in NDB 8.0.31; use WITH_NDB instead to build MySQL NDB Cluster. (NDB 8.0.30 and earlier: Use WITH_NDBCLUSTER.)
