That has been the plan for a long time, but now is the time that we have to start worrying about this. It was unclear until now whether or not GMP would switch to LGPLv3 or stay LGPLv2 or later. Now it seems that all GNU projects are switching to *GPLv3 or greater. > have switched to GPLv3 is not the reaction of other projects, but > rather the problem itself.

The only other player directly relevant to Sage that has a move to make is Singular. So far as I can tell, everybody else is already GPL version 2 or greater. > Anyway, GMP has been stale for... 5 years? And I gather that GSL is > not critical.

Anyway, I put the chances of a viable GMP fork in the next year at 1% (see below). It would be very useful to figure out what the situation is with Singular's licensing plans. Do they have a mailing list or something? -- William Why I think GMP won't be fork: Torbjörn is really the organizing force behind GMP, as far as I can tell, and he seems completely OK with LGPLv3 as a license for GMP. I don't know of any serious players who have the necessary resources and who are interested in forking GMP, and the license change from LGPLv2 to LGPLv3 likely has no impact on Maple and almost none on Magma. Basically before any of this LGPLv3 stuff, various people have made noise about forking GMP for more serious reasons, and nothing happened, so I doubt it would happen now. --~--~---------~--~----~------------~-------~--~----~ To post to this group, send email to sage-devel@googlegroups.com To unsubscribe from this group, send email to [EMAIL PROTECTED] For more options, visit this group at http://groups.google.com/group/sage-devel URLs: http://sage.scipy.org/sage/ and http://modular.math.washington.edu/sage/ -~----------~----~----~----~------~----~------~--~---
