<title>Installation of Ed</title>
|
|
|
|
<para>Ed is an optional package. The only program on a normal LFS system
|
|
that uses ed is patch. But these days, ed patch files are quite rare in
|
|
favour of the diff format patch files. So, if you personally have no
|
|
need to use ed, you can skip it.</para>
|
|
|
|
<para>Install Ed by running the following commands:</para>
|
|
|
|
<para><screen><userinput>cp buf.c buf.c.backup &&</userinput>
|
|
<userinput>sed 's/int u/int u, sfd/' buf.c.backup | \</userinput>
|
|
<userinput> sed '/.*\*mktemp.*/d' | \</userinput>
|
|
<userinput> sed 's/.*if (mktemp.*/ sfd = mkstemp(sfn);\</userinput>
|
|
<userinput> if ((sfd == -1) || (sfp = fopen (sfn, "w+")) == NULL)/' > buf.c</userinput>
|
|
<userinput>./configure --prefix=/usr &&</userinput>
|
|
<userinput>make &&</userinput>
|
|
<userinput>make install &&</userinput>
|
|
<userinput>mv /usr/bin/ed /usr/bin/red /bin</userinput></screen></para>
