    <para><parameter>C_EXTRA_FLAGS=-fno-strict-aliasing</parameter>: This
    environment variable adjusts the compiler optimization to avoid failures in
    the testsuite and other operations.</para>

    <para><parameter>--libexecdir=/usr/sbin</parameter>: This switch installs
    the <command>mysqld</command> daemon and the
    <command>mysqlmanager</command> program in an appropriate location.</para>

    <para><parameter>--localstatedir=/srv/mysql</parameter>: This switch
    forces <application>MySQL</application> to use
    <filename class='directory'>/srv/mysql</filename> for database files and
    other variable data.</para>

    <para><parameter>--enable-thread-safe-client</parameter>: This
    switch compiles a thread-safe <application>MySQL</application> client
    library.</para>

    <para><parameter>--enable-assembler</parameter>: This switch allows using
    assembler versions of some string functions.</para>

    <para><parameter>--enable-local-infile</parameter>: This switch enables
    the <quote>LOAD DATA INFILE</quote> SQL statement.</para>

    <para><parameter>--with-unix-socket-path=/var/run/mysql</parameter>:
    This switch puts the unix-domain socket into the
    <filename class="directory">/var/run/mysql</filename> directory instead of
    the default <filename class="directory">/tmp</filename>.</para>

    <para><parameter>--without-bench</parameter>: This switch skips building
    the benchmark suite.</para>

    <para><parameter>--without-readline</parameter>: This switch forces the
    build to use the system copy of <application>readline</application> instead

    international character sets within the suite.</para>

    <para><command>make testdir=...</command>: This installs the test suite in
    <filename class='directory'>/tmp/mysql</filename>. The test suite is not
    required, nor does it function properly on an installed version of
    <application>MySQL</application>, so it is removed in the next step.</para>

    <para><command>ln -v -sf mysql/libmysqlclient{,_r}.so* .</command>: This
    command makes the <application>MySQL</application> shared libraries
    available to other packages at run-time.</para>

      <para>There are several default configuration files available in

      use. Create <filename>/etc/my.cnf</filename> using the following command

      <para>Further configuration requires that the

      the server using the following commands as the <systemitem
