  22 <title>Installation of Psmisc</title>
  23
  24 <para>Prepare Psmisc for compilation:</para>
  25
  26 <screen><userinput>./configure --prefix=/usr --exec-prefix=/</userinput></screen>
  27
  28 <para>The meaning of the configure option:</para>
  29
  30 <itemizedlist>
  31 <listitem><para><userinput>--exec-prefix=/</userinput>: This causes the
  32 binaries to be installed in <filename>/bin</filename> and not in
  33 <filename>/usr/bin</filename>. As the Psmisc programs are often used in
  34 bootscripts, they should be available also when the <filename>/usr</filename>
  35 filesystem isn't mounted.</para></listitem>
  36 </itemizedlist>
  37
  38 <para>Compile the package:</para>
  39
  40 <screen><userinput>make</userinput></screen>
  41
  42 <para>And install it:</para>
  43
  44 <screen><userinput>make install</userinput></screen>
  45
  46 <para>There is no reason for the <filename>pstree</filename> and
  47 <filename>pstree.x11</filename> programs to reside in
  48 <filename class="directory">/bin</filename>. We therefore move them to
  49 <filename class="directory">/usr/bin</filename>. Also, there is no need
  50 for <filename>pstree.x11</filename> to exist as a separate program. We
  51 therefore make it a symbolic link to <filename>pstree</filename>:</para>
  52
  53 <screen><userinput>mv /bin/pstree* /usr/bin
  54 ln -sf pstree /usr/bin/pstree.x11</userinput></screen>
  55
  56 <para>By default Psmisc's <userinput>pidof</userinput> program isn't installed.
  57 Generally, this isn't a problem because we later install the Sysvinit package,
  58 which provides a better <userinput>pidof</userinput> program. But if you're not
  59 going to use Sysvinit, you should complete the installation of Psmisc by
  60 creating the following symlink:</para>
  61
  62 <screen><userinput>ln -s killall /bin/pidof</userinput></screen>
