我可以使用Qt LGPL许可证并销售我的应用程序没有任何限制吗？ [英] Can I use Qt LGPL license and sell my application without any kind of restrictions?

问题描述

我想开始一个跨平台项目。我有我的研究，现在我几乎肯定Qt是正确的交易。这里有一个很大的障碍：许可。

我想卖我的项目，我也不想给出任何与我的工作相关的来源或支付许可证。

我检查并注意到Qt提供了商业和开源解决方案。

我听说过很多有关Qt许可的冲突说法，困惑了我。
$ b $有人说，即使我使用LGPL版本的Qt，我仍然需要提交我的代码。

这是正确的吗？

有人可以给我一个简单的解释Qt许可证和告诉我，如果我可以卖出我的应用程序没有任何限制或完全没有？

我也将欣赏，如果任何人可以告诉我任何其他等同Qt的跨平台开发没有任何限制。

I want to start a cross-platform project. I had my researches and now I am almost certain Qt is the right deal. There is a big obstacle here though: licensing.
I want to sell my project and I also don't want to give out any source related to my work or pay for a license.
I checked and noticed Qt offers both commercial and open source solutions.
I have heard to many conflicting sayings on Qt licensing which confused me alot.
Some say that even if I use LGPL version of Qt, I still need to submit my code.
Is this correct?
Can someone give me a simple explanation on Qt licenses and tell me if I can sell my application without any kind of restrictions at all or not?
I would also appreciate if anyone could tell me any other equivalents to Qt for cross-platform development without any restrictions.

推荐答案

只是动态链接到Qt。如果你动态链接到LGPL库，没有什么可担心的。

Just dynamically link to Qt. If you dynamically link to LGPL libraries, there's nothing to worry about.

如果你静态链接到他们，你可以只分发你的目标文件你会很好。

If you statically link to them, you can just distribute your object files (not your source code), and you'll be fine.

LGPL的想法是，最终用户必须能够用他们想要的版本替换LGPL库。动态链接到LGPL库允许你这样做，静态链接和分发你的目标文件。只要你这样做，你可以卖你封闭的源程序所有你想要的。

The idea of the LGPL is that the end user has to be able to replace the LGPL library with a version they want. Dynamically linking to the LGPL library lets you do that, as does statically linking and distributing your object files. So long as you do this, you can sell your closed source program all you want.

当然，LGPL还有比这更多，但这是相关的部分。

Of course, there's more to the LGPL than just this, but that's the relevant part.
