6.21.1. 安装 Ncurses
</h2>
</div>
<p>准备编译 Ncurses：
</p>
<pre class="userinput"><kbd class="command">./configure --prefix=/usr --with-shared --without-debug</kbd></pre>
<p>编译软件包：</p>
<pre class="userinput"><kbd class="command">make</kbd></pre>
<p>
这个软件包没有附带测试程序。
</p>
<p>
安装软件包：
</p>
<pre class="userinput"><kbd class="command">make install</kbd></pre>
<p>赋予 ncurses 库文件可执行的权限：
</p>
<pre class="userinput"><kbd class="command">chmod 755 /usr/lib/*.5.4</kbd></pre>
<p>修正一个不应该有可执行权限的库文件：
</p>
<pre class="userinput"><kbd class="command">chmod 644 /usr/lib/libncurses++.a</kbd></pre>
<p>把库文件移到更合理的 <tt class="filename">/lib</tt> 目录里：
</p>
<pre class="userinput"><kbd class="command">mv /usr/lib/libncurses.so.5* /lib</kbd></pre>
<p>由于库文件移动了，所以有的符号链接就指向了不存在的文件。需要重新创建这些符号链接：
</p>
<pre class="userinput"><kbd class="command">ln -sf ../../lib/libncurses.so.5 /usr/lib/libncurses.so
ln -sf libncurses.so /usr/lib/libcurses.so</kbd></pre>
