<h3>
|
|
注意
|
|
</h3>
|
|
<p>
|
|
如果你是为 32 位的 x86 系统编译，但是你的 CPU 可以运行 64 位代码
|
|
<span class=
|
|
"emphasis"><em>而且</em></span> 环境中你有指定的<code class=
|
|
"envar">CFLAGS</code>，那么配置脚本会尝试配置为 64 位并导致失败。用下面的
|
|
命令激活配置命令来避免这个问题：
|
|
</p>
|
|
<pre class="userinput">
|
|
<kbd class="command"><em class=
|
|
"parameter"><code>ABI=32</code></em> ./configure ...</kbd>
|
|
</pre>
|
|
</div>
|
|
<p>
|
|
准备编译 GMP:
|
|
</p>
|
|
<pre class="userinput">
|
|
<kbd class="command">./configure --prefix=/usr \
|
|
--enable-cxx \
|
|
--docdir=/usr/share/doc/gmp-6.0.0a</kbd>
|
|
</pre>
|
|
<div class="variablelist">
|
|
<p class="title">
|
|
<strong>新配置选项的含义:</strong>
|
|
</p>
|
|
<dl class="variablelist">
|
|
<dt>
|
|
<span class="term"><em class=
|
|
"parameter"><code>--enable-cxx</code></em></span>
|
|
</dt>
|
|
<dd>
|
|
<p>
|
|
这个参数启用 C++ 支持
|
|
</p>
|

</dd>
|
|
<dt>
|
|
<span class="term"><em class=
|
|
"parameter"><code>--docdir=/usr/share/doc/gmp-6.0.0a</code></em></span>
|
|
</dt>
|
|
<dd>
|
|
<p>
|
|
这个变量指定保存文档的正确位置。
|
|
</p>
|
|
</dd>
|
|
</dl>
|
|
</div>
|
|
<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 GMP 的测试套件至关重要，任何情况下都不能跳过。
|
|
</p>
|
|
</div>
|
|
<p>
|
|
查看结果:
|
|
</p>
|
|
<pre class="userinput">
|
|
<kbd class="command">make check 2>&1 | tee gmp-check-log</kbd>
|
|
</pre>
|
|
<p>
|
|
确认测试套件中所有的 188 个测试都通过了。通过输入下面的命令检查结果：
|
|
</p>
|
|
<pre class="userinput">
|
|
<kbd class=
|
|
"command">awk '/tests passed/{total+=$2} ; END{print total}' gmp-check-log</kbd>
|
|
</pre>
|
|
<p>
|
|
安装软件包和文档：
|
|
</p>
|
