Licensing

[ravivundavalli]

Wish to know does this violate licensing.
Qgis is just as an example, it can be Grass or Ossim or any other Open GIS as well

Example: I love Qgis and I have added some code to Qgis as a C++ programmer, thus giving the necessary customization for my specific client. I compile it and distribute the Executable, as part of my package deal.
Does this violate any license of Qgis.

IFAIK, yes: if you distribute the executables, you have to distribute also
the source, for all GPL programs.
All the best.

Yes, it does.

Mateusz, note that the link you provide is referring to GPL v2. In the
latest GPL, the term "to all third parties" has disappeared. As
mentioned in the faq, you have to provide the source "to the program's
users".

So, Ravi, you have to provide the source code of your modifications to
your client (not to everybody). As long as you do that, I don't think
that you violate the licence. You have to be aware that your client
will have the right to distribute your source code without seeking
your approval (the code is under GPL).

Hi Emmanuel,

Thanks for correction. This issue only tells me that if in doubt
a lawyer is your best friend :-)

Here another recommendation:
http://producingoss.com/
- Read it in English
   - On the web
      - 2. Getting Started
         -   Starting From What You Have
            -   Choosing a License and Applying It

Best,
Markus
