GMP is *LGPL*. > In the threads I've read, some workarounds are proposed on linux and > OsX, but I didn't see anything on windows. > > Is the situation still the same ? > Does anybody know a work-around to make a closed-source programm in > haskell without violating the GPL ? It is LGPL, which is a very important distinction. It just must be possible to replace the libgmp component with another that has been modified - you can't actively prevent people replacing the libgmp component. Supporting this is trivial with a dynamically linked / DLL libgmp. With a statically linked one, it is also possible, since the API calls to libgmp are specified. This shouldn't prevent commercial use -- lots of other companies have decided this is OK. You just need to be aware of it. -- Don _______________________________________________ Haskell-Cafe mailing list Haskell-Cafe@haskell.org http://www.haskell.org/mailman/listinfo/haskell-cafe
