      <application>Valgrind</application> is an instrumentation framework for
      building dynamic analysis tools. There are Valgrind tools that can
      automatically detect many memory management and threading bugs, and
      profile programs in detail. Valgrind can also be used to build new
      tools.

    <title>Installation of Valgrind</title>

<!-- Fix applied upstream, remove in valgrind 1.14-->
    <para>
      First, fix a bug, which has been exposed by glibc-2.26:
    </para>

<screen><userinput>sed -i '1904s/4/5/' coregrind/m_syswrap/syswrap-linux.c</userinput></screen>

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

<screen><userinput>sed -i 's|/doc/valgrind||' docs/Makefile.in &amp;&amp;

./configure --prefix=/usr \
            --datadir=/usr/share/doc/valgrind-&valgrind-version; &amp;&amp;
make</userinput></screen>

    <note>
     <para>
       To run the tests for this package, valgrind requires a version of the
       /lib/ld-2.26.so (or later) library with debugging symbols present.
       Normally in LFS these debugging symbols are stripped at the end of
       Chapter 6. To get this library, glibc must be rebuilt with the current
       glibc version using the same compiler that was used to build LFS. The
       ld.so can then be renamed to ld-2.26.so.dbg and copied to /lib.
       Then a symlink needs to be changed:</para>

<screen role="nodump"><userinput>ln -sfv ld-2.26.so.dbg /lib/ld-linux-x86-64.so.2</userinput></screen>
    
     <para>
       Adjust the above instruction as needed for a 32-bit system or for a
       different version of glibc.
     </para>

     <para>
       In addition, other glibc libraries with debugging symbols present
       may be needed for some tests.
     </para>
    </note>

    <para>
      To test the results, issue: <command>make regtest</command>. The tests
      may hang forever if <xref linkend="gdb"/> is not installed. Some tests
      are known to hang also, depending on the version of glibc. Problematic
      tests can be disabled by changing the <userinput>prereq:</userinput> line
      in the corresponding <filename>.vgtest</filename> file to
      <userinput>prereq: false</userinput>. For example:
    </para>

<!-- For valgrind-3.12.0, the pth_cond_destroy_busy test hangs forever because
     of some change in glibc-2.25. Should be fixed in next versions of
     valgrind.-->
<screen><userinput>sed -e 's@prereq:.*@prereq: false@' \
    -i {helgrind,drd}/tests/pth_cond_destroy_busy.vgtest</userinput></screen>

    <note>
      <para>
        The <application>OpenMP</application> tests are skipped if libgomp
        has been compiled with <option>--enable-linux-futex</option> (the
        default). If needed, just recompile the libgomp library from
        the gcc build tree, passing <option>--disable-linux-futex</option>
        to configure, storing the library to some place and changing the link
        from <filename>/usr/lib/libgomp.so.1</filename> to point to the new
        library.
      </para>
