关于GPL和专有软件 [英] About GPL and proprietary software
问题描述
在软件许可方面，我不会感到非常自信。但是
有些情况我想让自己清楚。我对
特别感兴趣的是什么？GPL许可证何时成为限制性的？
比如说公司有专有的软件产品只有
适用于MySQL，没有其他数据库系统。以下情况是否合法？
合法？
1）该公司在专有许可下销售他的产品，并将其留给客户设置需要MySQL服务器。或者也许帮助客户在没有额外费用的情况下设置MySQL。
2）客户每月向该公司支付使用其专有费用的费用
$ b使用公司服务器中托管的MySQL的$ b软件。
3）该公司在CD上以专有许可证销售他的产品
，其中还包括MySQL作为免费奖金（含源代码）。
如果这些情况有效，那么MySQL的GPL许可证（或者任何其他软件的b * b）在何时成为真正的限制一个
的专有公司？

提示9：如果您的
加入列的数据类型不匹配，计划员将忽略您选择索引扫描的愿望
I don''t feel very confident when it comes to software licenses. But
there are some cases I would like to make myself clear. What I am
particulary interested in is when does GPL license become restrictive?
For example say a company has a proprietary software product that only
works with MySQL and no other database system. Are the following cases
legal?
1) This company sells his product under proprietary license and leaves
it up to the client to set up required MySQL server. Or perhaps helps
the client with seting up MySQL with or without extra fee.
2) Clients pay monthly fee to this company for using their proprietary
software which uses MySQL hosted in the companys server.
3) This company sells his product under proprietary license on the CD
which also includes MySQL as free bonus (with source code).
If these cases are valid, then when does GPL license for MySQL (or any
other software in that matter) become truly restrictive for a
proprietary company?

如果这些情况有效，那么什么时候GPL许可MySQL（或任何其他软件对于
专有公司是否真的受到限制？

这既不是GNU也不是MySQL邮件列表。我建议你把问题带到其中一个地方，因为你会得到更好的答案。

为什么要问关于MySQL（一个GPL许可的产品），在一个
PostgreSQL（一个BSD许可的产品）邮件列表上????
是这样的可能：
IANAL，但根据我的理解
（1）专有的s / w动态链接到GPL共享库
没有破坏GPL。
（2）*静态*链接到GPL的专有软件。图书馆已经打破了GPL。
（3）专有的s / w说话到GPL s / w通过管道，网络
链接等，不会打破GPL。
据推测，PostgreSQL是BSD的原因之一行货是
以避免这样的问题。

提示5：您查看了我们广泛的常见问题解答吗？
http://www.postgresql.org/docs/faqs/FAQ.html
Why are you asking about MySQL (a GPL-licensed product), on a
PostgreSQL (a BSD-licensed product) mailing list????
Be that as it may:
IANAL, but according to my understanding
(1) proprietary s/w that dynamically links to "GPL" shared libraries
has not broken the GPL.
(2) proprietary s/w that *statically* links to "GPL" libraries has
broken the GPL.
(3) proprietary s/w that "speaks" to "GPL" s/w via a pipe, network
link, etc., does not break the GPL.
Presumably, one of the reasons that PostgreSQL is BSD-licensed is
to avoid issues like this.

这取决于MySQL客户端库是否为LGPL（最高版本为3）
或GPL（从版本4开始）。但是PostgreSQL论坛可能是一个讨论这个问题的完全不合适的地方。

消息可以干净地通过邮件列表
That depends on whether the MySQL client library is LGPL (up to version 3)
or GPL (from version 4 on). But a PostgreSQL forum is probably an
entirely inappropriate place to discuss this.
