Can the buyer resell the program under LGPL licence[SOLVED]



  • let's say that i made an application and used libs under LGPL licence and i include the licence terms "LGPL" in the distribution ,and someone buys the application can he resell it or reditribute it?

    That depends on what license you choose for your application. It does not have to be LGPL.

    But in general, the answer is a big yes. Both LGPL and GPL don't talk about money, but software freedoms. They can be given away, sold, copied, rented, etc.

    i would also say yes, but in such a case he has to state that the work is based on your work.



  • It depends on the license you put on your code. The LGPL libraries can be sold, copied, given away, whatever. But they can also already be downloaded from this very website, so they don't need your application for that and there is probably little value to be gained that way. What is important is the licence of your own work. That you use LGPL libs does not affect the license of your own work, so you can still forbid further distribution for your own program.

    That is the major difference between GPL and LGPL: the first imposes restrictions on the licence that can be used for applications linking to the library under GPL, while the LGPL does not restrict that choice.

    If you want to prevent users from further distributing your software, don't use LGPL or GPL for your own code.

    Andre is right, i somehow misread your post and thought your application is also released under the terms of LGPL.



  • thank you all for the replies
    @raven-worx : i think you missunderstood the post because of the title (... program under LGPL licence),i don't want to licence my work as LGPL,but i have to include the LGPL licence in the distribution,so someone will read it and he will say this is free that's what had me worried
    @Andre :i just want to check one more time,in the last sentence,
    you mean don't use LGPL/GPL libraries ,or
    don't licence the work under LGPL/GPL



  • No, the last sentence is about your code. The libraries are not your code: you do not hold the copy rights to those. However, as they (the libraries) are licenced to you under the terms of the LGPL, you are allowed to (re-) distribute them, as long as you stick to the conditions for that (basically: don't modify them, or if you do, provide your modifications to those libraries along with your program.)

    So: again, you can use LGPL libraries and still keep your application closed source, linked against those libraries. LGPL does not 'contaminate' your own work.



  • "LGPL does not ‘contaminate’ your own work"
    that what i was looking for ,thanks
