All that is needed to make this legal is to (a)... (b) give users access to another version of the proprietary program that links GMP dynamically. Wow, I didn't realize that. Now I understand Bulat. In a project of any serious size and complexity, the use of static or dynamic linking is often architechted in and cannot be changed. (b) is a sufficient condition, but not necessary; there are other ways to satisfy the license. It's also possible to just distribute, for example, the .o file(s) and a way to link them with a GMP to get the final result; this doesn't even reveal your source-code any more than your program being dynamically linked, at least if you do it right -- right? ~Isaac ___ Glasgow-haskell-users mailing list Glasgow-haskell-users@haskell.org http://www.haskell.org/mailman/listinfo/glasgow-haskell-users

It doesn't matter. In a typical commercial development environment, you just don't have any control over that. At some companies I've gotten free software included in products in a way that required certain extra files from the 3rd party to be included inside our installation package - such as a source code tarball, GNU license, and such. It wasn't easy, but I've done it. But to change the way our own code is distributed - forget it. If you happen to be in a situation where the LGPL thing can be integrated as a dynamic library, fine. Otherwise, I don't see it. -Yitz ___ Glasgow-haskell-users mailing list Glasgow-haskell-users@haskell.org http://www.haskell.org/mailman/listinfo/glasgow-haskell-users

What I should have written was that it appears to require GHC to be distributed under the GPL. I don't believe it does. It does. GHC's codebase is a mix of BSD3, LGLP, and GPL. They are perfectly compatible. See http://www.fsf.org/licensing/licenses/index_html .
