From http://www.gnu-pascal.de/contrib/eike/ I downloaded GPC interfaces to mySQL, contributed by Eike Lange - thanks Eike for contributing them. With some necessary changes, I got things working on Mac OS X.
Would you like to contribute these changes?
Now, we have an "original work" copyrighted by MySQL AB and licensed under the GPL, plus a "new work" based on the "original work" copyrighted partly by Eike Lange and licensed under the LGPL. From a lawyers point of view - I don't think that this is all correct.
At least in my MySQL version (3.23.x), which I think also Eike's work was based upon, mysql.h is under the LGPL, not GPL.
This is very remarkable, to say the least. Here is a copy of the header of mysql.h (version 4)
I heard they changed the license in version 4. Of course they can do it.
You mention version 3.23.x. According to the MySQL website "versions of the MySQL database server prior to 3.23.19 were licensed under the MySQL FREE PUBLIC LICENSE (Version 4, March 5, 1995)", see http://www.mysql.com/products/licensing/mypl.html. It further states "The license was changed to the GNU GPL as of version 3.23.19, and commercial licenses are also available."
I think in 3.23.>=19 (or so) the server (and perhaps client programs) were GPL, but the client libraries LGPL.
Since the original work (mysql.h) is under LGPL, the derived work (mysql.pas) must be under the LGPL as well or under the GPL without exceptions (which the LGPL explictly permits).
MySQL being licensed under LGPL can not possibly be correct. Someone must have changed the header.
Not MySQL as a whole, but the client libraries.
Also, I asked MySQL AB. They are perfectly happy if a Pascal MySQL unit would state that "the rights of MySQL AB have to be respected as outlined on http://www.mysql.com/products/licensing/faq.html".
You might want to search for LGPL on that page.
