Python嵌入问题。 [英] Python embedding question.

问题描述

对不起我几周前发布了一个类似的问题，但我没有得到

答案。我想在具有有限

资源的设备上嵌入Python应用程序，尤其是存储限制。有没有办法将Python

解释器缩减为一组迫切需要的模块？或者是否有一个

方法可以将gzip压缩模块随时解压缩到内存中

当它们被访问时？那会更好。


另外，是否有一个Python模块包含嵌入式应用程序所需的所有东西

，如图形，声音等等。我是否需要使用各种绑定到cairo，Qt或类似的库？

是否有网站可以帮助做出这些决定？

我真的看了很多地方但还没找到合适的

解决方案，所以我在这里要求希望有人有经验

与该主题。


问候，

托马斯。

Hi,

Sorry I''ve posted a similar question some weeks ago, but I got no
answers. I want to embed a Python application on a device with limited
resources, esp. storage limitations. Is there a way to reduce the Python
interpreter to a set of modules that''s urgently needed? Or is there a
method to have gzipped modules that are unzipped on the fly into memory
when they''re accessed? That would be even better.

Additionally, is there a Python module that contains all the stuff
needed for an embedded application like graphics, sound etc. or do I
have to use the various bindings to libraries like cairo, Qt or similar?
Is there a site that helps with those decisions?

I''ve really looked at a lot of places but haven''t found a suitable
solutions yet, so I''m asking here in hope that someone has experience
with that topic.

Regards,
Thomas.

Which solutions did you rule out?

- Python + Qt，因为它对我的计划来说肯定有点过分。我只需要
需要简单的图形和一些声音，没有小部件。基本上我正在寻找

的东西非常轻量级，有绘制图形的方法

基元和渲染字体 - 没有复杂的小部件，窗口，

滚动条等。而且，例如，Qt库是一个真正的

重量级，约有。单独为qt-3.3.8 10 MB。


- cairo / pango也一样，我写了一个测试程序（在C中，我是

必须说）有10个库的动态链接，大小都是250kb

。这对于一个小型嵌入式设备来说非常重要。


我想要一个解决方案，一共不超过10MB，并且口译员

如果包含所有模块，则为60 MB。我无法想象没有人在这之前遇到过这个问题吗？我正试图不再发明这个问题：^）

- Python + Qt, because it''s definitely overkill for my plans. I only
need simple graphics and some sound, no widgets. Basically I''m looking
for something really lightweight that has methods for drawing graphic
primitives and renders fonts -- no complicated widgets, windows,
scrollbars and the like. And, for example, the Qt library is a real
heavyweight with approx. 10 MB for qt-3.3.8 alone.

- The same holds for cairo/pango, I''ve written a test program (in C, I
must say) that has dynamic links to 10 libraries that are all like 250kb
in size. That''s a lot for a small embedded device.

I''d like a solution that''s not over 10MB altogether, and the interpreter
comes at a 60 MB if all modules are included. I can''t imagine noone has
had this problem before... and I''m trying to not invent the wheel again :^)

你试过pygame吗？我认为它的占地面积很小。


问候，Uwe

Did you try pygame ? I think it has a small footprint.
