I am trying to try out SAGE on my Dell Latitude D410 laptop, which has a dual boot system running Vista and Ubuntu [Linux tony-laptop 2.6.32-33-generic #72-Ubuntu SMP Fri Jul 29 21:08:37 UTC 2011 i686 GNU/ Linux]. I downloaded SAGE 4.7 yesterday but the installation process warned that it might not run because of a lack of pni. That seems to be correct:

occurred in Sage. This probably occurred because a *compiled* component of Sage has a bug in it and is not properly wrapped with sig_on(), sig_off(). You might want to run Sage under gdb with 'sage -gdb' to debug this. Sage will now terminate. ------------------------------------------------------------------------ /home/tony/Documents/sage-4.7.1-linux-32bit-ubuntu_10.04_lts-i686- Linux/local/bin/sage-sage: line 301: 2734 Illegal instruction sage-ipython "$@" -i tony@tony-laptop:~/Documents/sage-4.7.1-linux-32bit-ubuntu_10.04_lts- i686-Linux$ ***************************************************************************************** Today I tried the SageLive option, which I notice contains Sage 4.6, and that seems to run fine (although I haven't had time to try it out thoroughly). Given that my laptop is not all that old, I am surprised that it would not run the current version. Questions: (1) Is that fixable, either in the short term or long term? (2) Is there somewhere to download Sage 4.6 to run on my Ubuntu system either until this problem is fixed or I can afford a newer laptop? -- To post to this group, send email to sage-support@googlegroups.com To unsubscribe from this group, send email to sage-support+unsubscr...@googlegroups.com For more options, visit this group at http://groups.google.com/group/sage-support URL: http://www.sagemath.org
