我觉得MySQL已经不再是GPL的了,挂着一个GPL的名义而已.哪有这种GPL!!!要这样,大家的cvs和gcc都是盗版的了.shit
a) If you include the MySQL server in your non Open Source application, you need a commercial licence for the MySQL server
b) If you include one of the MySQL drivers in your non Open Source application (so that your application can run with MySQL), you need a commercial licence for the driver(s) in question. The MySQL drivers currently include an ODBC driver, a JDBC driver and the C language library.
c) If you use MySQL Software within your organisation and you don't want to risk it falling under the GPL license, you are welcome to purchase a commercial license.
d) Many users opt for the commercial licence simply because under it MySQL AB takes responsibility for its products. Under the GPL licence, there are no warranties or representations from the developer (i.e. from MySQL AB).
You need to purchase commercial non-GPL MySQL licenses:
If you distribute MySQL Software with your non open source software,
If you want warranty from MySQL AB for the MySQL software,
If you want to support MySQL development.
As long as you never distribute (internally or externally) the MySQL Software in any way, you are free to use it for powering your application, irrespective of whether your application is under GPL or other OSI approved license or not.
If your application is not licensed under GPL or compatible OSI license approved by MySQL AB and you intend to distribute MySQL software (be that internally or externally), you must first obtain a commercial license to the MySQL software in question.
More specifically:
a) If you include the MySQL server in your non Open Source application, you need a commercial licence for the MySQL server
b) If you include one of the MySQL drivers in your non Open Source application (so that your application can run with MySQL), you need a commercial licence for the driver(s) in question. The MySQL drivers currently include an ODBC driver, a JDBC driver and the C language library.
c) If you use MySQL Software within your organisation and you don't want to risk it falling under the GPL license, you are welcome to purchase a commercial license.
