To compile just the MySQL client libraries and client programs and not the server, use the --without-server option:

shell> ./configure --without-server

If you have no C++ compiler, some client programs such as mysql cannot be compiled because they require C++.. In this case, you can remove the code in configure that tests for the C++ compiler and then run ./configure with the --without-server option. The compile step should still try to build all clients, but you can ignore any warnings about files such as mysql.cc. (If make stops, try make -k to tell it to continue with the rest of the build even if errors occur.)

If you want to build the embedded MySQL library (libmysqld.a), use the --with-embedded-server option.

If you don't want your log files and database directories located under /usr/local/var, use a configure command something like one of these:

shell> ./configure --prefix=/usr/local/mysql
shell> ./configure --prefix=/usr/local \
           --localstatedir=/usr/local/mysql/data

The first command changes the installation prefix so that everything is installed under /usr/local/mysql rather than the default of /usr/local. The second command preserves the default installation prefix, but overrides the default location for database directories (normally /usr/local/var) and changes it to /usr/local/mysql/data.

You can also specify the installation directory and data directory locations at server startup time by using the --basedir and --datadir options. These can be given on the command line or in an MySQL option file, although it is more common to use an option file. See Section 4.2.3.3, “Using Option Files”.

This option specifies the port number on which the server listens for TCP/IP connections. The default is port 3306. To listen on a different port, use a configure command like this:

shell> ./configure --with-tcp-port=3307

If you are using Unix and you want the MySQL socket file location to be somewhere other than the default location (normally in the directory /tmp or /var/run), use a configure command like this:

shell> ./configure \
           --with-unix-socket-path=/usr/local/mysql/tmp/mysql.sock

The socket file name must be an absolute path name. You can also change the location of mysql.sock at server startup by using a MySQL option file. See Section B.5.4.5, “How to Protect or Change the MySQL Unix Socket File”.

If you want to compile statically linked programs (for example, to make a binary distribution, to get better performance, or to work around problems with some Red Hat Linux distributions), run configure like this:

shell> ./configure --with-client-ldflags=-all-static \
           --with-mysqld-ldflags=-all-static

If you are using gcc and don't have libg++ or libstdc++ installed, you can tell configure to use gcc as your C++ compiler:

shell> CC=gcc CXX=gcc ./configure

When you use gcc as your C++ compiler, it does not attempt to link in libg++ or libstdc++. This may be a good thing to do even if you have those libraries installed. Some versions of them have caused strange problems for MySQL users in the past.

The following list indicates some compilers and environment variable settings that are commonly used with each one.

In most cases, you can get a reasonably optimized MySQL binary by using the options from the preceding list and adding the following options to the configure line:

--prefix=/usr/local/mysql --enable-assembler \
--with-mysqld-ldflags=-all-static

The full configure line would, in other words, be something like the following for all recent gcc versions:

CFLAGS="-O3 -mpentiumpro" CXX=gcc CXXFLAGS="-O3 -mpentiumpro \
-felide-constructors -fno-exceptions -fno-rtti" ./configure \
--prefix=/usr/local/mysql --enable-assembler \
--with-mysqld-ldflags=-all-static

The binaries we provide on the MySQL Web site at http://dev.mysql.com/downloads/ are all compiled with full optimization and should be perfect for most users. See Section 2.2, “Installing MySQL from Generic Binaries on Unix/Linux”. There are some configuration settings you can tweak to build an even faster binary, but these are only for advanced users. See Section 7.5.1, “How Compiling and Linking Affects the Speed of MySQL”.

If the build fails and produces errors about your compiler or linker not being able to create the shared library libmysqlclient.so.N (where N is a version number), you can work around this problem by giving the --disable-shared option to configure. In this case, configure does not build a shared libmysqlclient.so.N library.

By default, MySQL uses the latin1 (cp1252 West European) character set. To change the default set, use the --with-charset option:

shell> ./configure --with-charset=CHARSET

CHARSET 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. (Additional character sets might be available. Check the output from ./configure --help for the current list.)

The default collation may also be specified. MySQL uses the latin1_swedish_ci collation by default. To change this, use the --with-collation option:

shell> ./configure --with-collation=COLLATION

To change both the character set and the collation, use both the --with-charset and --with-collation options. The collation must be a legal collation for the character set. (Use the SHOW COLLATION statement to determine which collations are available for each character set.)

With the configure option --with-extra-charsets=LIST, you can define which additional character sets should be compiled into the server. LIST is one of the following:

Clients that want to convert characters between the server and the client should use the SET NAMES statement. See Section 5.1.5, “Session System Variables”, and Section 9.1.4, “Connection Character Sets and Collations”.

To configure MySQL with debugging code, use the --with-debug option:

shell> ./configure --with-debug

This causes a safe memory allocator to be included that can find some errors and that provides output about what is happening. See MySQL Internals: Porting.

As of MySQL 5.1.12, using --with-debug to configure 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.

To cause the Debug Sync facility to be compiled into the server, use the --enable-debug-sync option. This facility is used for testing and debugging. When compiled in, Debug Sync is disabled by default. 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.

Debug Sync is also compiled in if you configure with the --with-debug option (which implies --enable-debug-sync), unless you also use the --disable-debug-sync option.

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

The --enable-debug-sync and --disable-debug-sync options were added in MySQL 5.1.41.

If your client programs are using threads, you must compile a thread-safe version of the MySQL client library with the --enable-thread-safe-client configure option. This creates a libmysqlclient_r library with which you should link your threaded applications. See Section 21.9.16.2, “How to Make a Threaded Client”.

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-dir=no|bundled|DIR option provides control over compression library support. The value no explicitly disables compression support. bundled causes the zlib library bundled in the MySQL sources to be used. A DIR path name specifies the directory in which to find the compression library sources.

It is possible to build MySQL with large table support using the --with-big-tables option.

This option causes the variables that store table row counts to be declared as unsigned long long rather than unsigned long. This enables tables to hold up to approximately 1.844E+19 ((2³²)²) rows rather than 2³² (~4.295E+09) rows. Previously it was necessary to pass -DBIG_TABLES to the compiler manually in order to enable this feature.

Run configure with the --disable-grant-options option to cause the --bootstrap, --skip-grant-tables, and --init-file options for mysqld to be disabled. For Windows, the configure.js script recognizes the DISABLE_GRANT_OPTIONS flag, which has the same effect. The capability is available as of MySQL 5.1.15.

This option allows MySQL Community Server features to be enabled. Additional options may be required for individual features, such as --enable-profiling to enable statement profiling. This option was added in MySQL 5.1.24. It is enabled by default as of MySQL 5.1.28; to disable it, use --disable-community-features.

When given with --enable-community-features, the --enable-profiling option enables the statement profiling capability exposed by the SHOW PROFILE and SHOW PROFILES statements. (See Section 12.4.5.33, “SHOW PROFILES Syntax”.) This option was added in MySQL 5.1.24. It is enabled by default as of MySQL 5.1.28; to disable it, use --disable-profiling.

See Section 2.1, “General Installation Guidance”, for options that pertain to particular operating systems.

See Section 5.5.6.2, “Using SSL Connections”, for options that pertain to configuring MySQL to support secure (encrypted) connections.

Several configure options apply to plugin selection and building:

--with-plugins=PLUGIN[,PLUGIN]...
--with-plugins=GROUP
--with-plugin-PLUGIN
--without-plugin-PLUGIN

PLUGIN is an individual plugin name such as csv or archive.

As shorthand, GROUP is a configuration group name such as none (select no plugins) or all (select all plugins).

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

configure --help shows the following information pertaining to plugins:

--with-plugins can take a list of one or more plugin names separated by commas, or a plugin group name. The named plugins are configured to be built as static plugins.

--with-plugin-PLUGIN configures the given plugin to be built as a static plugin.

--without-plugin-PLUGIN disables the given plugin from being built.

If a plugin is named both with a --with and --without option, the result is undefined.

For any plugin that is not explicitly selected or disabled, it is selected to be built dynamically if it supports dynamic build, and not built if it does not support dynamic build. (Thus, in the case that no plugin options are given, all plugins that support dynamic build are selected to be built as dynamic plugins. Plugins that do not support dynamic build are not built.)
