IANAL either, but I do read wikipedia. So by way of clarification...<div><br></div><div>Everything I've read makes a clear distinction between GPL and LGPL such that GPL code <span class="Apple-style-span" style="font-weight: bold;">can not</span> be embedded in or linked to a closed source application. Period. Whereas L-GPL licensed code can be linked to a closed source application. </div>
<div><br></div><div>See: <a href="http://en.wikipedia.org/wiki/GNU_Lesser_General_Public_License">http://en.wikipedia.org/wiki/GNU_Lesser_General_Public_License</a></div><div><br></div><div>So if the individual wants to link to GPL licensed code/libraries and is willing to make his code GPL then fine. He can still run a commercial business based on this code, as many people do. </div>
<div><br></div><div>But if he wants to keep his code under some closed-source license then he <span class="Apple-style-span" style="font-weight: bold;">can not </span>link to or embed any GPL licensed code or library.</div>

Disclaimer: IANAL. Get legal advice from your lawyer before embarking<br>
on your million dollar enterprise.<br>

<br>
I'll correct you, because, as stated above, you are misrepresenting at<br>
best, and wrong at worst. ;-)<br>
<br>
GPL does not prevent you from making money. GPL only requires that if<br>
you modify the code that is under GPL, then you must redistribute the<br>
modified code under GPL. Granted this may not be easy to figure out in<br>
real world scenarios, but consider the following --<br>
<br>
Let's say ShapeLib is published under GPL (I don't know whether or not<br>
it is; this is only for illustration purpose). Let's say, MapServer<br>
utilizes ShapeLib, but doesn't modify ShapeLib, but uses ShapeLib as<br>
is. Let's say, MapServer's creator decides to make millions off of<br>
MapServer, Inc. He is under no obligation to release the source code<br>
of MapServer, but he is obligated to release the source code of<br>
ShapeLib, which is no big deal, because the source code of ShapeLib is<br>
already available to anyone.<br>
<br>
On the other hand, let's say, ShapeLib is modified to perform better,<br>
or differently, for MapServer. Now, there is an obligation to release<br>
the source code to the modified version of ShapeLib no matter what the<br>
value of that value-added might be. That is what the GPL obligates.<br>
MapServer itself is still governed by whatever license that its<br>
creator decides to apply.<br>
