25.9.2. mysql_config — Get Compile Options for Compiling Clients

mysql_config provides you with useful information for compiling your MySQL client and connecting it to MySQL.

mysql_config supports the following options:

  • --cflags

    Compiler flags to find include files and critical compiler flags and defines used when compiling the libmysqlclient library.

  • --include

    Compiler options to find MySQL include files. (Note that normally you would use --cflags instead of this option.)

  • --libmysqld-libs, --embedded

    Libraries and options required to link with the MySQL embedded server.

  • --libs

    Libraries and options required to link with the MySQL client library.

  • --libs_r

    Libraries and options required to link with the thread-safe MySQL client library.

  • --port

    The default TCP/IP port number, defined when configuring MySQL.

  • --socket

    The default Unix socket file, defined when configuring MySQL.

  • --version

    Version number for the MySQL distribution.

If you invoke mysql_config with no options, it displays a list of all options that it supports, and their values:

shell> mysql_config
Usage: /usr/local/mysql/bin/mysql_config [options]
Options:
  --cflags         [-I/usr/local/mysql/include/mysql -mcpu=pentiumpro]
  --include        [-I/usr/local/mysql/include/mysql]
  --libs           [-L/usr/local/mysql/lib/mysql -lmysqlclient -lz
                    -lcrypt -lnsl -lm -L/usr/lib -lssl -lcrypto]
  --libs_r         [-L/usr/local/mysql/lib/mysql -lmysqlclient_r
                    -lpthread -lz -lcrypt -lnsl -lm -lpthread]
  --socket         [/tmp/mysql.sock]
  --port           [3306]
  --version        [4.0.16]
  --libmysqld-libs [-L/usr/local/mysql/lib/mysql -lmysqld -lpthread -lz
                    -lcrypt -lnsl -lm -lpthread -lrt]

You can use mysql_config within a command line to include the value that it displays for a particular option. For example, to compile a MySQL client program, use mysql_config as follows:

shell> CFG=/usr/local/mysql/bin/mysql_config
shell> sh -c "gcc -o progname `$CFG --cflags` progname.c `$CFG --libs`"

When you use mysql_config this way, be sure to invoke it within backtick (‘`’) characters. That tells the shell to execute it and substitute its output into the surrounding command.
