(I think so.)
This is not really an answer, but a remark. SAGE64 only got introduced by mabshoff when he was trying to port Sage to OS X 64-bit last year. So for 4-5 year of building Sage on Linux, SAGE64 didn't even exist. > > - is the file SAGE_LOCAL/lib/sage-64.txt used anywhere except sage- > check-64? > > - is sage-check-64 and/or the variable SAGE64 used anywhere besides > sage-spkg (and the spkg-install files for the various spkgs) and > possibly sage-build? > > -- > John > > -- > 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 > -- 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
