6.15.1. 安装 MPFR
|
||
</h2>
|
||
<p>
|
||
首先，使用下面的补丁修复上游已解决的多个漏洞：
|
||
</p>
|
||
<pre class="userinput">
|
||
<kbd class="command">patch -Np1 -i ../mpfr-3.1.2-upstream_fixes-3.patch</kbd>
|
||
</pre>
|
||
<p>
|
||
准备编译 MPFR：
|
||
</p>
|
||
<pre class="userinput">
|
||
<kbd class="command">./configure --prefix=/usr \
|
||
--enable-thread-safe \
|
||
--docdir=/usr/share/doc/mpfr-3.1.2</kbd>
|
||
</pre>
|
||
<p>
|
||
编译软件包并生成 HTML 文档：
|
||
</p>
|
||
<pre class="userinput">
|
||
<kbd class="command">make
|
||
make html</kbd>
|
||
</pre>
|
||
<div class="admon important">
|
||
<img alt="[Important]" src="../images/important.png" />
|
||
<h3>
|
||
重要
|
||
</h3>
|
||
<p>
|
||
该章节 MPFR 的测试套件至关重要，任何情况下都不能跳过。
|
||
</p>
|
||
</div>
|
||
<p>
|
||
检查结果确认通过了所有的测试：
|
||
</p>
|
||
<pre class="userinput">
|
||
<kbd class="command">make check</kbd>
|
||
</pre>
|
||
<p>
|
||
安装软件包以及文档：
|
||
</p>
|
||
<pre class="userinput">
|
||
<kbd class="command">make install
|
||
make install-html</kbd>
|
