RE: RE: [Mono-devel-list] ByteFX developmentHi All,

Please, correct me if I'm wrong, but I believe that the licence of the MySql
database only allows you to develop apps that are open source. If you are
intending on selling/distributing a commercial product that uses MySql as
the backend, then you are required you to purchase a comercial licence for

Because of this, the LGPL version of ByteFX is only of any use to open
source projects. If you want to sell a comercial product, you need to
purchase the licence, which I guess will also include their commercial
version of the GPL library that MySql provides.

I think this might eliminate the need to develop the LGPL version if the
main intent is that it can be use in commercial applications.

Hope I 'm wrong in my understandind of the MySql Licence but I think it's
worth checking before doing the work...

Thanks for your great work mono developers :)

  Yes, I agree, that is more of an issue if you are intending to sell a
product based on GPL code.

  However, I would think that you could pay them a fee and obtain the same
code under a different license
  if the time came to actually making money out of it.

  The licensing of MySQL makes it less than appealing for commercial use.
As I mentioned in my first email, the license has changed from lgpl to gpl
meaning that any applications that use the MySQL connector become gpl'ed.
Here is the link to the connector downloads page:


  Here is the GNU description of whether you can link or not:


  Given this it seems very useful to maintain development of a lgpl MySQL
