Trac tickets #1547, #1886, #2108, and #5741 look relevant. Especially #1547 points to the instructions here: http://math-atlas.sourceforge.net/devel/atlas_devel/atlas_devel.html#SECTION00070000000000000000 #1886 [0] also has this short recipe from William: 1. sage -f -m atlas-3.8.p7 2. cd spkg/build/atlas-3.8.p7 3. cd ATLAS-build/ARCHS 4. make ArchNew 5. make tarfile [0] http://trac.sagemath.org/sage_trac/ticket/1886#comment:1 Cheers, Burcin --~--~---------~--~----~------------~-------~--~----~ To post to this group, send email to sage-devel@googlegroups.com To unsubscribe from this group, send email to sage-devel-unsubscr...@googlegroups.com For more options, visit this group at http://groups.google.com/group/sage-devel URLs: http://www.sagemath.org -~----------~----~----~----~------~----~------~--~---
