You never have to reveal your source code when your code uses an LGPL libary. If you modify the LGPL library source then you do have to release the modified library source under the LGPL -- but this does not mean you need to release the code that uses your modified library. http://www.gnu.org/licenses/lgpl.html "When a program is linked with a library, whether statically or using a shared library, the combination of the two is legally speaking a combined work, a derivative of the original library. The ordinary General Public License therefore permits such linking only if the entire combination fits its criteria of freedom. The Lesser General Public License permits more lax criteria for linking other code with the library." If you dynamically link then there is little to do, as the users can easily switch to a modified library. If you statically link you must supply object code (not source code): "If you link other code with the library, you must provide complete object files to the recipients, so that they can relink them with the library after making changes to the library and recompiling it. And you must show them these terms so they know their rights." So there is a difference in static vs dynamic linking -- with static linking you have to make (at least) your object code available. -- Chris _______________________________________________ Haskell mailing list Haskell@haskell.org http://www.haskell.org/mailman/listinfo/haskell
