6.56.1. Installation of Gzip
|
|
</h2>
|
|
<p>
|
|
Prepare Gzip for compilation:
|
|
</p>
|
|
<pre class="userinput">
|
|
<kbd class="command">./configure --prefix=/usr --bindir=/bin</kbd>
|
|
</pre>
|
|
<p>
|
|
Compile the package:
|
|
</p>
|
|
<pre class="userinput">
|
|
<kbd class="command">make</kbd>
|
|
</pre>
|
|
<p>
|
|
To test the results, issue:
|
|
</p>
|
|
<pre class="userinput">
|
|
<kbd class="command">make check</kbd>
|
|
</pre>
|
|
<p>
|
|
Install the package:
|
|
</p>
|
|
<pre class="userinput">
|
|
<kbd class="command">make install</kbd>
|
|
</pre>
|
|
<p>
|
|
Move some programs that do not need to be on the root filesystem:
|
|
</p>
|
|
<pre class="userinput">
|
|
<kbd class="command">mv -v /bin/{gzexe,uncompress,zcmp,zdiff,zegrep} /usr/bin
|
|
mv -v /bin/{zfgrep,zforce,zgrep,zless,zmore,znew} /usr/bin</kbd>
