    <para>
      <application>GDB</application>, the GNU Project debugger, allows you
      to see what is going on <quote>inside</quote> another program while it
      executes -- or what another program was doing at the moment it crashed.
      Note that <application>GDB</application> is most effective when tracing
      programs and libraries that were built with debugging symbols and not
      stripped.

    <title>Installation of GDB</title>

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

<screen><userinput>./configure --prefix=/usr --with-system-readline &amp;&amp;
make</userinput></screen>

    <para>
      Optionally, to build the API documentation using
      <xref linkend="doxygen"/>, run:
    </para>

<screen><userinput>make -C gdb/doc doxy</userinput></screen>

    <para>
      To run the test suite, issue the following commands:
    </para>

<screen><userinput>pushd gdb/testsuite &amp;&amp;
make     site.exp &amp;&amp;
echo "set gdb_test_timeout 120" >> site.exp &amp;&amp;
runtest TRANSCRIPT=y
popd</userinput></screen>

    <para>
      There are many problems with the test suite. Your results will depend on 
      installed compilers, as well as whether or not you are running it locally
      or remotely. Although we do extend the timeout above, there are still many
      tests that will time out. Note that by changing the timeout value, the 
      number of tests is no longer conserved. There are also failures associated
      with system readline 6.x among others. Unexpected failures should be about
      0.5%.

    <para>
      Now, as the <systemitem class="username">root</systemitem> user:
    </para>

<screen role="root"><userinput>make -C gdb install</userinput></screen>

    <para>
      If you have built the API documentation, it is now in gdb/doc/doxy.
      You can install it (as the <systemitem class="username">root</systemitem>
      user):
    </para>

<screen role="root"><userinput>install -d /usr/share/doc/gdb-&gdb-version; &amp;&amp;
