Isn't one of the reasons of having the LGPL, the ability to link a GPL'ed library/class library into a non-gpl'ed application without the final result being GPL'ed? As long as you meet the LGPL license (ie: making available the source to the library, etc, etc), would you be ok?

Well, I don't think you need a commercial license. You don't link anything with GPL code. You don't modify any GPL code (and if you did, you could still supply the source). Just like it's legal to sell Linux for big bucks, you can sell Cygwin at any cost you like. Generally, whats not allowed, is linking non-open-source code with GPL code. However, this isn't a matter of source code at all. Now a commercial application using binaries compiled from GPL source: that's very common. Many, many softwarehouses develop using GCC and sell closed-source software. Many commercial websites run Linux/Apache/MySQL. Non problem at all. > -- Want to unsubscribe from this list?
