You are trying to build a 'C' extension in Windows. The <a href="https://docs.python.org/2/extending/windows.html" rel="noreferrer">Python docs</a> have a basic introduction to what this means.

In practice, you need to install a 'C' build environment, then compile and link the code. You have chosen the MinGW environment, but there are <a href="https://wiki.python.org/moin/WindowsCompilers" rel="noreferrer">others available</a>. Given that you have instructions for MinGW, let's stick with that, so at this point you just need to run the compiler... 

For 'C' applications, there is usually a complete toolchain to keep track of what files depend on others, what external dependencies you might need and the precise build settings you need to use. In this case, the libraries are using <a href="https://www.gnu.org/software/automake/faq/autotools-faq.html" rel="noreferrer">autotools</a>. In order to invoke them, you need to run the commands that they show in the install instructions. So, for example:

<pre><code>cd C:\src\agg-2.5
./autogen.sh; make
cd C:\src\potrace-1.15.win64
./configure; make
</code></pre>

If that all works fine, you should find the library files located in the directories mentioned later in the instructions. You should then be able to run your python build as per the rest of the instructions, install the extension and use it!

blocks|key|160895|text|作为另一个选择，因为这是一个问题，即使我解决了它，我也不能确定我的工作的用户也能解决它，就是使用一个纯python端口的potrace。完全公开，我移植了这个。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|160896|根据不同的因素，这就像在一两秒钟内完成速度慢了500倍。但是，由于它是纯python，所以您可以确保它对任何人都适用，不会出现任何兼容性问题。|160897|https://github.com/tatarize/potrace|offset|length|160898|或者pip+install+potracer，我试着使它与pypotrace相同的API作为一个插入替代。我还写了一个很好的命令行姐妹包。如果我在API中搞砸了任何需要更改的内容，可以随意提出问题。但是，它将绕过安装问题，因为它是纯python代码。|style|CODE|160899|entityMap|0|LINK|mutability|MUTABLE|url^0|0|0|0|Z|0|0|2|K|0^^$0|@$1|2|3|4|5|6|7|S|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|T|8|@]|9|@]|A|$]]|$1|D|3|E|5|6|7|U|8|@]|9|@$F|V|G|W|1|X]]|A|$]]|$1|H|3|I|5|6|7|Y|8|@$F|Z|G|10|J|K]]|9|@]|A|$]]|$1|L|3|-4|5|6|7|11|8|@]|9|@]|A|$]]]|M|$N|$5|O|P|Q|A|$R|E]]]]

As another option since this was a problem and even if I solved it, I couldn't be sure users of my work could also solve it, is to use a pure python port of potrace. Full disclosure, I ported this.
It's like 500x slower completing in a second or two, depending on various factors. But, since it's pure python you can be sure it'll work for anybody without any compatibility problems.
<a href="https://github.com/tatarize/potrace" rel="nofollow noreferrer">https://github.com/tatarize/potrace</a>
Or <code>pip install potracer</code> I tried to make it fit the same API as pypotrace to be a drop-in replacement. I also wrote a nice command-line sister package. If I messed up anything in the API where it requires a change feel free to raise an issue. But, it'll bypass installation problems since it's purely python code.

I would like to install Potrace on my Windows 10 Computer and I will be using it with python 2.7.5. I am following the installation instruction from this site.( <a href="https://pypi.python.org/pypi/pypotrace" rel="nofollow noreferrer">https://pypi.python.org/pypi/pypotrace</a>) for Windows.

<h1>What I did so far</h1>

I installed MinGW – following these YouTube instructions [<a href="https://www.youtube.com/watch?v=DHekr3EtDOA]" rel="nofollow noreferrer">https://www.youtube.com/watch?v=DHekr3EtDOA]</a> 

I also download Agg-2.5 and potrace-1.15.win64 and put these 2 folders inside C:/src (see Picture 1)

<h1>Issue</h1>

However, I am stuck at this specific point of the installation instructions. It says:

<blockquote>
 I extracted both packages in my <code>C:\src</code> folder. Both are easy to build by executing <code>./configure; make</code> and <code>./autogen.sh;</code> make respectively, on MSYS prompt.
</blockquote>

<a href="https://i.stack.imgur.com/hjrsB.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/hjrsB.png" alt="picture3"></a>

I have no idea how what that means or how to do it. I did find MSYS prompt but I have no idea what to write in the prompt to complete this step (see Picture 2).
