[sage-devel] Re: Sage 4.0.1.alpha0 linbox trying to build before blas was installed
Hi David, atlas-3.8.3.p2 (needed hack suggested by ATLAS developer) Note blas is not in that list. But linbox is trying to build, which claims to need blas Actually, isn't ATLAS providing our BLAS? So maybe somehow the linbox script can't find it after whatever changes were made to the atlas spkg? Or something else completely? :) -cc --~--~-~--~~~---~--~~ 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 -~--~~~~--~~--~--~---
