<h3 id="orgheadline1">静态链接</h3>
<div class="outline-text-3" id="text-1-1">
<p>
静态链接是将应用程序调用的库函数拷贝到可执行文件里面。当多个程序调用相同的函数，将会出现同一个函数的多个拷贝。 
</p>
</div>
</div>

<div class="outline-3">
<h3 id="orgheadline2">动态链接</h3>
<div class="outline-text-3" id="text-1-2">
<p>
动态链接是程序运行时动态地加载所需的函数。比如windows下的dll文件或者linux下的so文件，从这些引入库中拷贝的是重定位信息，然后在需要的时候从这些文件中导入相应的函数。

<div class="outline-2">
<h2 id="orgheadline4">python对接win32 api模块</h2>
<div class="outline-text-2" id="text-2">
<p>
python对接win32 api模块推荐使用pywin32模块。
</p>
</div>
</div>


<div class="outline-2">
<h2 id="orgheadline5">在windows下安装python的模块</h2>
<div class="outline-text-2" id="text-3">
<p>
如果有网络那么推荐就使用pip命令来安装，是很方便的，无需多言。如果没有网络的情况那么推荐下载exe或者whl包来安装，其中whl包就是对应的pip install命令，使用的pip wheel技术。
</p>

<p>
如果实在需要手工安装，通常纯python写的模块没什么问题，就是一些模块使用了cython技术等，其中cython那一块很是引起了我的兴趣。如果有c代码，那么需要安装visual studio2010开发环境，这很不方便。还有一个不是很完美的替代方案就是安装mingw程序，然后写一个distutils.cfg文件，内容如下：
</p>

<pre>
[build]
compiler = mingw32
</pre>

<p>
然后将其放入 <code>C:\Python34\Lib\distutils</code> 里面，cython可以安装成功，但是有的又不行，是一个不太完美的备选方案。

<h2 id="orgheadline6">cygwin环境下pygmentize的编码问题</h2>
<div class="outline-text-2" id="text-4">
<p>
在cygwin环境下，安装好emacs-win32之后，相关配置跟上，就可以很自如的使用emacs的org模式了，其中额外pygments宏包出现了编码问题，加上 <code>-O encoding=utf-8</code> 之后可以解决，代码如下所示：
</p>

<pre>
(format "pygmentize -O encoding=utf-8  -f html -l %s" lang)
</pre>
</div>
</div>


<div class="outline-2">
<h2 id="orgheadline7">windows下cmd编码问题</h2>
<div class="outline-text-2" id="text-5">
<p>
在windows下通过geany调用python解释器，是进入的cmd终端模式，目前（win7）默认的是GBK编码，最好改成UTF-8编码。
