6.35.1. 安装 Readline
|
||
</h2>
|
||
<p>
|
||
首先安装补丁修复一些上游标记的 bug：
|
||
</p>
|
||
<pre class="userinput">
|
||
<kbd class=
|
||
"command">patch -Np1 -i ../readline-6.3-upstream_fixes-3.patch</kbd>
|
||
</pre>
|
||
<p>
|
||
重装 Readline 会使旧的库移动到 <libraryname>.old。
|
||
通常来说这并不是什么问题，但一些情况下可能引起
|
||
<span class=
|
||
"command"><strong>ldconfig</strong></span> 链接错误。可以通过
|
||
下面的两个 sed 命令避免这个问题：
|
||
</p>
|
||
<pre class="userinput">
|
||
<kbd class="command">sed -i '/MV.*old/d' Makefile.in
|
||
sed -i '/{OLDSUFF}/c:' support/shlib-install</kbd>
|
||
</pre>
|
||
<p>
|
||
准备编译 Readline：
|
||
</p>
|
||
<pre class="userinput">
|
||
<kbd class=
|
||
"command">./configure --prefix=/usr --docdir=/usr/share/doc/readline-6.3</kbd>
|
||
</pre>
|
||
<p>
|
||
编译软件包：
|
||
</p>
|
||
<pre class="userinput">
|
||
<kbd class="command">make SHLIB_LIBS=-lncurses</kbd>
|
||
</pre>
|
||
<div class="variablelist">
|
||
<p class="title">
|
||
<strong>make 选项的含义：</strong>
|
||
</p>
|
||
<dl class="variablelist">
|
||
<dt>
|
||
<span class="term"><em class=
|
||
"parameter"><code>SHLIB_LIBS=-lncurses</code></em></span>
|
||
</dt>
|
||
<dd>
|
||
<p>
|
||
该选项强制 Readline 链接到 <code class=
|
||
"filename">libncurses</code> (实际上， <code class=
|
||
"filename">libncursesw</code>) 库。
|
||
</p>
|
||
</dd>
|
||
</dl>
|
||
</div>
|
||
<p>
|
||
该软件包没有测试套件。
|
||
</p>
|
||
<p>
|
||
安装软件包：
|
||
</p>
|
||
<pre class="userinput">
|
||
<kbd class="command">make SHLIB_LIBS=-lncurses install</kbd>
|
||
</pre>
|
||
<p>
|
||
现在移动动态库到更合适的位置并修正一些符号链接：
|
||
</p>
|
||
<pre class="userinput">
|
||
<kbd class="command">mv -v /usr/lib/lib{readline,history}.so.* /lib
|
||
ln -sfv ../../lib/$(readlink /usr/lib/libreadline.so) /usr/lib/libreadline.so
|
||
ln -sfv ../../lib/$(readlink /usr/lib/libhistory.so ) /usr/lib/libhistory.so</kbd>
|
||
</pre>
|
||
<p>
|
||
如果需要的话，安装帮助文档：
|
||
</p>
|
||
<pre class="userinput">
|
||
<kbd class=
|
||
"command">install -v -m644 doc/*.{ps,pdf,html,dvi} /usr/share/doc/readline-6.3</kbd>
|
||
</pre>

||
