1. for example, program A says:

and few lines later:

how is this first part compatible with gpl?

2. program B says:


and


since i know that ultravnc is modified/improved vnc which is under original copyright, how can this mod be copyrighted under some1 else?


edit: basically what i wanna figure out what happens with the copyrights when some thingy is under gpl, and is that related to specific country and its law or what?

I think this is the catch:

You can only set licenses for what you have the copyright. You can't take someone else's code and slap the GPL on it - you don't own that code. (there are exceptions, like copyleft)

Therefore, the UltraVNC devs can only license under the GPL the code THEY wrote. The code written by the original VNC developers must remain under whatever license they chose.

Of course, that leads to several issues. GPL is know not to be very compatible with other open source licenses.

The usual GPL mess. And GNU freaks still flame me when I say the GPL is such a mess that even Stallman probably doesn't understands it fully. :B

I'd rather say the usual CDex license fucking... I'm not sure if this is in any way compliant to the GPL, but as always the CDex author doesn't seem to care about copyrights all that much himself...

dont know about cdex, but i think i figured the vnc example,

the law says something like if the original work is modified by another author, that is considered as the new copyright (but they dont really speak about computer code), so ultravnc is actually copyrighted by the 'new' author, but at the same time it is under original gpl which says that the old author must be named as well, and it is if you dig on the readme files long enough, however exclusive copyright on this mod is in the hands of the new person, lmao. So basically it looks like copyrights and gpl are kinda walking each its own way.

another funny thing is that the original author has the exclusive rights to the original code, so for example vnc authors can publish the original code under commercial license anytime, but ultravnc ones cant since that is gpled..., however the vnc authors cant take the ultravnc code (for any other license) since that is under gpl now as well...
