This is, I think, incorrect. The GPL includes a standard "linking exception". Look for this part....
A "Standard Interface" means an interface that either is an official standard defined by a recognized standards body, or, in the case of interfaces specified for a particular programming language, one that is widely used among developers working in that language. If what you say is correct, for example, it would be impossible to produce GPL code which would run on Windows or Mac since in all of these cases the OS itself is non-GPL (nor even free). But it is possible to do this -- you can run linux, for example, in windows user space with no legal issues, or Emacs, or cygwin. Or, indeed, write a GPL program in Java. In the case of Clojure, you can link a GPL library to Clojure itself. So, in this case, library G really is relevant. If G is GPLv3 and B uses it, then B must also be GPLv3 because of this. So, the issue is, what "other Clojure libraries" is A dependent on. If it is dependant on the "standard interface" there is not a problem. If not, then I don't think the program can be legally distributed. Phil Jozef Wagner <[email protected]> writes: > Do you want to distribute binaries (.class files) of the program B?
