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.

  • -DCMAKE_BUILD_TYPE=type

    The type of build to produce:

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

    • 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.

  • -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.

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, FEDERATED, and PARTITION (partitioning support). Examples: 

-DWITH_ARCHIVE_STORAGE_ENGINE=1
-DWITH_BLACKHOLE_STORAGE_ENGINE=1

To build MySQL with support for NDB Cluster, use the WITH_NDBCLUSTER option.

Note

WITH_NDBCLUSTER is supported only when building NDB Cluster using the NDB Cluster sources. It cannot be used to enable clustering support in other MySQL source trees or distributions. In NDB Cluster source distributions, it is enabled by default. See Building NDB Cluster from Source on Linux, and Compiling and Installing NDB Cluster from Source on Windows, for more information.

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_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_EXAMPLE_STORAGE_ENGINE=0
-DWITH_FEDERATED_STORAGE_ENGINE=0
-DWITH_PARTITION_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_EXAMPLE_STORAGE_ENGINE=1
-DWITHOUT_FEDERATED_STORAGE_ENGINE=1
-DWITHOUT_PARTITION_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

  • -DCOMPILATION_COMMENT=string

    A descriptive comment about the compilation environment.

  • -DDEFAULT_CHARSET=charset_name

    The server character set. By default, MySQL uses the latin1 (cp1252 West European) 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, utf8, utf8mb4, utf16, utf16le, utf32. The permissible character sets are listed in the cmake/character_sets.cmake file as the value of CHARSETS_AVAILABLE.

    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 latin1_swedish_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_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).

  • -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.

  • -DENABLE_DTRACE=bool

    Whether to include support for DTrace probes. For information about DTrace, wee Tracing mysqld Using DTrace

    This option is deprecated because support for DTrace is deprecated in MySQL 5.7 and is removed in MySQL 8.0.

  • -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.

  • -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. (Prior to MySQL 5.7.6, it was enabled by default.) 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: Visual Studio 2013 (Windows); GCC 4.4 or Clang 3.3 (Linux); Developer Studio 12.5 (Solaris server); Developer Studio 12.2 or GCC 4.4 (Solaris client library); Clang 3.3 (macOS), Clang 3.3 (FreeBSD). To disable this check, use -DFORCE_UNSUPPORTED_COMPILER=ON.

  • -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.

  • -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 5.7.19.

  • -DWIN_DEBUG_NO_INLINE=bool

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

  • -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_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. This option was added in MySQL 5.7.19.

  • -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.

    This option was added in MySQL 5.7.19.

  • -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.

      As of MySQL 5.7.11, -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.

    This option was added in MySQL 5.7.19.

  • -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.

    As of MySQL 5.7.18, enabling WITH_DEBUG also enables Debug Sync. 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.

  • -DWITH_EDITLINE=value

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

    WITH_EDITLINE replaces WITH_LIBEDIT, which has been removed.

  • -DWITH_EMBEDDED_SERVER=bool

    Whether to build the libmysqld embedded server library.

    Note

    The libmysqld embedded server library is deprecated as of MySQL 5.7.17 and has been removed in MySQL 8.0.

  • -DWITH_EMBEDDED_SHARED_LIBRARY=bool

    Whether to build a shared libmysqld embedded server library.

    Note

    The libmysqld embedded server library is deprecated as of MySQL 5.7.17 and has been removed in MySQL 8.0.

  • -DWITH_EXTRA_CHARSETS=name

    Which extra character sets to include:

    • all: All character sets. This is the default.

    • complex: Complex character sets.

    • none: No extra character sets.

  • -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, in which case CMake downloads the distribution from GitHub.

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

  • -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_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.

    This option was added in MySQL 5.7.11.

  • -DWITH_LDAP=value

    Internal use only. This option was added in MySQL 5.7.29.

  • -DWITH_LIBEVENT=string

    Which libevent library to use. Permitted values are bundled (default) and system. Prior to MySQL 5.7.31, if you specify system, the system libevent library is used if present, and an error occurs otherwise. In MySQL 5.7.31 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 and X Plugin.

  • -DWITH_LIBWRAP=bool

    Whether to include libwrap (TCP wrappers) support.

  • -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_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.

  • -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.

    This option was added in MySQL 5.7.17.

  • -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.

    • system: Use the package installed on the system.

    Other values are ignored, with a fallback to bundled.

    This option was added in MySQL 5.7.12.

  • -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. This option was added in MySQL 5.7.12.

  • -DWITH_SASL=value

    Internal use only. This option was added in MySQL 5.7.29. 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:

      • yes: Use the system OpenSSL library if present, else the library bundled with the distribution.

      • bundled: Use the SSL library bundled with the distribution. This is the default prior to MySQL 5.7.28. As of 5.7.28, this is no longer a permitted value and the default is system.

      • system: Use the system OpenSSL library. This is the default as of MySQL 5.7.28.

    • 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_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_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_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:

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

    • system: Use the system zlib library.

Compiler Flags

  • -DCMAKE_C_FLAGS="flags"

    Flags for the C compiler.

  • -DCMAKE_CXX_FLAGS="flags"

    Flags for the C++ compiler.

  • -DWITH_DEFAULT_COMPILER_OPTIONS=bool

    Whether to use the flags from cmake/build_configurations/compiler_options.cmake.

    Note

    All optimization flags are carefully chosen and tested by the MySQL build team. Overriding them can lead to unexpected results and is done at your own risk.

  • -DSUNPRO_CXX_LIBRARY="lib_name"

    Enable linking against libCstd instead of stlport4 on Solaris 10 or later. This works only for client code because the server depends on C++98.

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"
