    <title>Installation of FLAC</title>

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

<screen><userinput>patch -Np1 -i ../flac-&flac-version;-xmms_plugin_fix-1.patch &amp;&amp;
LIBS=-lm ./configure --prefix=/usr &amp;&amp;
make</userinput></screen>

    <para>If you have <application>Valgrind</application> version 3.0.0 or
    higher installed and you plan on running the test suites after passing the
    <option>--enable-valgrind-testing</option> parameter to
    <command>configure</command>, you need to issue the following command to
    change some test scripts:</para>

<screen><userinput>sed -i -e "s/logfile-fd/log-fd/" `grep -lr logfile-fd test/*sh`</userinput></screen>

    <para>To test the results, issue: <command>make check</command>. This
    test suite will take quite a while. Note that if you passed the
    <option>--enable-exhaustive-tests</option> and
    <option>--enable-valgrind-testing</option> parameters to
    <command>configure</command> and then run the test suite, it will take a
    <emphasis>very</emphasis> long time (up to 300 SBUs) and use about 375 MB
    of disk space.</para>

    <filename class="libraryfile">libFLAC</filename> uses a function from the math

    Passing the environment variable to <command>configure</command> satisfies
