    <title>Introduction to Valgrind</title>

    <para>
      <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>

    <para>
      First, make several changes that are required for Valgrind to function on
      systems with glibc-2.35 installed:
    </para>

<screen><userinput remap="pre">patch -Np1 -i ../valgrind-&valgrind-version;-upstream_fixes-1.patch</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>

    <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. A few test
       can fail in various suites. 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>

<screen role="nodump"><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>
    </note>

<!--  Note to maintainer: there is a long thread in ticket #5882 explaining
      why we do not provide instructions to rebuild the documentation.
      (still broken with TeXLive 2016) -->

    <title>Command Explanations</title>

    <para>
      <command>sed -i ... docs/Makefile.in </command>: This sed provides for
      installing the documentation in a versioned directory.
    </para>

    <para>
      <option>--enable-lto=yes</option>: This option allows building Valgrind
      with LTO (link time optimization).  This produces a smaller/faster
      Valgrind (up to 10%), but build time increases to about 5.5 SBU.
