    <title>Testing Berkeley DB</title>

    <para>You may want to skip ahead to <xref linkend="bdb-installation"/>. The
    test suite can take up to 150 SBUs and has a few bugs causing a report of
    <quote>Regression tests failed</quote>. However, running the test suite is
    a very exhaustive test of your hardware, perhaps pushing your machine
    harder (especially disk I/O) than it will ever see during production use.
    Note that you must have <application>Tcl</application> installed to run the
    test suite.</para>

    <para>Build for the <application>Berkeley DB</application> test by running
    the following commands:</para>

<screen><userinput>cd build_unix &amp;&amp;
../dist/configure --prefix=/usr \
                  --enable-test \
                  --enable-tcl  \
                  --with-tcl=/usr/lib &amp;&amp;
make</userinput></screen>

    <para>To test the results, start <command>tclsh</command>:</para>

<screen><userinput>tclsh</userinput></screen>

    <para>From the <command>tclsh</command> prompt (<prompt>%&nbsp;</prompt>),
    run:</para>

    <title>Installation of Berkeley DB</title>

    <!-- <para>The installation commands below are identical to the commands used
    in the LFS book. If you installed <application>Berkeley DB</application>
    in LFS, and you don't add anything to the <command>configure</command>
    script, you'll end up with exactly what you already have. The additional
    parameters you can use are listed in the Command Explanations section
    below.</para> -->

    <note>
      <para>If you plan on installing <application>Berkeley DB</application>
      with Java support, you should check the system for certain versions
      of <xref linkend="jdk"/> and <xref linkend="gmime"/>. Specifically, if
      <application>JDK</application>-6 Update X and the
      <command>uudecode</command> program from the
      <application>GMime</application> program is on the system, the build will
      fail (unless you run the modified <command>./configure</command> command
      shown below). You can run two commands (<command>javac -version</command>
      and <command>uudecode --version</command>) to determine what versions are
      installed. You can also download and run a shell script from
      <ulink url="&files-anduin;/jdk-uudecode-check.sh"/> that will alert
      you to a non-working condition. If the identified programs exist on the
      system, you must modify the
      <command>./configure</command> command as shown below.</para>

<screen><userinput>uudecode="no" ../dist/configure --(use the parameters shown below)</userinput></screen>
    </note>

    <para>Install <application>Berkeley DB</application> by running the
    following commands:</para>
