LGPL allows you to use and distribute the open source software with your application without releasing the source code for your application.

GPL requires you to release the source code of your application if you choose to use and distribute the GPL licensed open source software with your application. In other words, your application must also be licensed under the GPL.

The GPL vs. LGPL distinction determines whether you do/do not have to release the source for your application to anyone having a copy of the binary. Either way you can still sell the application.

blocks|key|1506880|text|GPL并不禁止您销售软件。但是，您必须将源代码提供给软件。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1506881|用法的问题稍微复杂一点。GNU/Linux是在GPL下发布的。没有任何东西禁止您编写在Linux下运行的软件，而不管您的软件的许可证是什么。但是，您不能将Linux与您的软件一起分发。对于需要成为程序一部分的库来说，这通常是一个问题。这就是LGPL许可证的目的。你可以编译一个你用gcc写的c程序(因此使用了来自gcc的LGPL许可运行时例程库)，并且仍然可以发布你的软件而不受GPL的限制。|1506882|我认为这就是它的大意。然而，这并不是任何法律建议。对于法律咨询，您必须保留一名注册律师，他可以为您提供适合您特定情况的法律建议。|1506883|希望这能有所帮助。|1506884|entityMap^0|0|0|0|0^^$0|@$1|2|3|4|5|6|7|J|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|K|8|@]|9|@]|A|$]]|$1|D|3|E|5|6|7|L|8|@]|9|@]|A|$]]|$1|F|3|G|5|6|7|M|8|@]|9|@]|A|$]]|$1|H|3|-4|5|6|7|N|8|@]|9|@]|A|$]]]|I|$]]

GPL does not forbid you to sell software. However you must make available the sources to the software. 

The question of usage is a little more complicated. GNU/Linux is released under the GPL. Nothing forbids you to write software that runs under Linux regardless of the licence of your software. However, you cannot distribute Linux together with your software. That is often a problem with libraries which need to be part of a program. That is what the LGPL licence is for. You can compile a c program you write with gcc (hence using LGPL licenced runtime routine libraries from gcc) and still release you software without the restrictions of the GPL. 

I think that is the general gist of it. However, this it not in any way legal advice. For legal advice you must retain a certified attorney who can give you legal advice fitting your particular circumstances.

Hope this helps.

If you cut and paste or link against GPL'd code into your application, your application must be licensed under GPL and you are then required to release the code. 

However, you can still sell your application and afaik, the only oblication is that you release the sourcecode to your customers.

If the library you link against is Lesser Gnu Public License aka LGPL then you dont need to release your own application's code but you are still required to release all modifications if you modified the lgpl'd code.

I am having trouble understanding the usage permissions of open source. I read somewhere that GPL or LGPL enforces that software that uses GPL software must also be released open-source. I want to create an application that uses some open-source image recognition library. Can I sell this application or does it have to be open source?

Thanks!

GPL and LGPL open source licensing restrictions

图像识别

Linux

我在理解开源的使用权限时遇到了问题。我在某处读到GPL或LGPL强制要求使用GPL软件的软件也必须是开源的。我想创建一个使用一些开源图像识别库的应用程序。我可以销售这个应用程序吗?或者它必须是开源的？谢谢!
