<title>Installation of Ed</title>
|
|
|
|
<note><para>Ed isn't something which many people use. It's installed here
|
|
because it can be used by the patch program if you encounter an ed-based patch
|
|
file. This happens rarely because diff-based patches are preferred these
|
|
days.</para></note>
|
|
|
|
<para>Ed normally uses the mktemp function to create temporary files in
|
|
<filename class="directory">/tmp</filename>, but this function contains a
|
|
vulnerability (see the section on Temporary Files in <ulink
|
|
url="http://en.tldp.org/HOWTO/Secure-Programs-HOWTO/avoid-race.html"/>). The
|
|
following patch makes Ed use mkstemp instead, which is the recommended way to
|
|
create temporary files.</para>
|
|
|
|
<para>Apply the patch:</para>
|
|
|
|
<screen><userinput>patch -Np1 -i ../&ed-patch;</userinput></screen>
|
|
|
|
<para>Now prepare Ed 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 forces the
|
|
programs to be installed into the <filename>/bin</filename> directory. Having
|
|
the programs available there is useful in the event of the
|
|
<filename>/usr</filename> partition being unavailable.</para></listitem>
|
|
</itemizedlist>
|
|
|
|
<para>Compile the package:</para>
|
|
|
|
<screen><userinput>make</userinput></screen>
|
|
|
|
<para>This package has a test suite available which can perform a number of
|
|
checks to ensure it built correctly. Should you choose to run it, the
|
|
following command will do so:</para>
|
|
|
|
<screen><userinput>make check</userinput></screen>
|
|
|
|
<para>Install the package:</para>
|
