According to GNU GPL I can copy code from a software foo which is released under GNU GPL license, and create another software bar then I should release bar under GNU GPL license. But if I release a binary of the software without the source code, then how would the author of foo know whether I have used his source?? And how can he protect his Free Software?
I know it is illegal and unethical, but it is possible. How to prevent such things?

or you can sue that person or company and see him in court. This is a common thing and has happened many times in the past. But the FSF is a very powerful lobby... in the past, FSF has won every such lawsuite and proprietary software vendours have had to roll back...

But catching someone with reverse engineering is like taking a chance. How will I know who has used which part of my code in which part of his code :shock:

As regards suing, if some company of Australia uses my code, do you think I will ever be able to sue them there? :roll:

Alternatively, if an Indian entity uses code of some foreign entity, then... only God can save him if he tries to sue him in India :lol: It would take 20 years to get over with the first round, then another 5-7 years for first appeal and then another 2-4 for appeal to Supreme Court :roll: You know how Indian Judiciary works!! :shock:

Say I copied source from a PHP software and compiled them using Turck - MMCache (ttp://sourceforge.net/projects/turck-mmcache/), then it is not possible to find out the code. Then how will I protect my source??
