<title>Installation of Psmisc</title>

<para>Prepare Psmisc for compilation:</para>

<screen><userinput>./configure --prefix=/usr --exec-prefix=""</userinput></screen>

|
|
|
<para>The meaning of the configure option:</para>
|
|
|
|
<itemizedlist>
|
|
<listitem><para><userinput>--exec-prefix=""</userinput>: This causes the
|
|
binaries to be installed in <filename>/bin</filename> instead of
|
|
<filename>/usr/bin</filename>. As the Psmisc programs are often used in
|
|
bootscripts, they should be available also when the <filename>/usr</filename>
|
|
file system isn't mounted.</para></listitem>
|
|
</itemizedlist>
|
|
|
|
<para>Compile the package:</para>
|
|
|
|
<screen><userinput>make</userinput></screen>
|
|
|
|
<para>Now install it:</para>
|
|
|
|
<screen><userinput>make install</userinput></screen>
|
|
|
|
<para>There is no reason for the <filename>pstree</filename> and
|
|
<filename>pstree.x11</filename> programs to reside in
|
|
<filename class="directory">/bin</filename>. We therefore move them to
|
|
<filename class="directory">/usr/bin</filename>. Also, there is no need
|
|
for <filename>pstree.x11</filename> to exist as a separate program. We
|
|
therefore make it a symbolic link to <filename>pstree</filename>:</para>
|
|
|
|
<screen><userinput>mv /bin/pstree* /usr/bin
|
|
ln -sf pstree /usr/bin/pstree.x11</userinput></screen>
|
|
|
|
<para>By default Psmisc's <command>pidof</command> program isn't installed.
|
|
Generally, this isn't a problem because we later install the Sysvinit package,
|
|
which provides a better <command>pidof</command> program. But if you're not
|
|
going to use Sysvinit, you should complete the installation of Psmisc by
|
|
creating the following symlink:</para>
|
|
|
|
<screen><userinput>ln -s killall /bin/pidof</userinput></screen>
