(1) I sometimes build Sage against GMP for testing purposes, and there is an spkg that does this too. (2) Remark: Since anyone using GMP could use MPIR, technically nothing fundamentally relies on GMP. (3) Getting anything changed at http://gmplib.org is difficult. For example, that page currently asserts * "MPIR, a renamed GMP based on an obsolete version of the GMP sources, maintained by a group of people with funding from Microsoft. This GMP version uses an old LGPL license (version 2.1), but has nevertheless taken code from current GMP and downgraded the license without our authorisation. See e.g., this page were they say "I have very carefully applied all GMP issued patches through 25/08/2008". They are still through the University of Washington network distributing MPIR tarballs with the LGPL 3 code as if they had a LGPL 2 license (2010-05-05)." I have written to them about 20 times to get this changed. I even wrote to the FSF about this, and they contacted me, did an audit, and made a specific list of one single minor item that had to be fixed on the MPIR website so that we would be in full compliance. We fixed that weeks ago. Yet still the above completely false statement remains on the GMP website. If anybody feels personally annoyed by how http://gmplib.org posts this false statements, the email addresses you can write to in order to complain are: gmp-disc...@gmplib.org, "Torbjorn Granlund" <t...@gmplib.org>, "license-violation" <license-violat...@gnu.org>, -- William -- William Stein Professor of Mathematics University of Washington http://wstein.org -- To post to this group, send an email to sage-devel@googlegroups.com To unsubscribe from this group, send an email to sage-devel+unsubscr...@googlegroups.com For more options, visit this group at http://groups.google.com/group/sage-devel URL: http://www.sagemath.org
