Hi, After using version 3 for over a year, it finally occured to me I should upgrade. When trying to start version 3.4 I get:
---------------------------------------------------------------------- | Sage Version 3.4, Release Date: 2009-03-11 | | Type notebook() for the GUI, and license() for information. | ---------------------------------------------------------------------- ********************************************************************** WARNING! This Sage install was built on a machine that supports instructions that are not available on this computer. Sage will likely fail with ILLEGAL INSTRUCTION errors! The following processor flags were on the build machine but are not on this computer: sse4_1 Email http://groups.google.com/group/sage-support for help. To remove this warning and make Sage start, just delete /home/bixbyr/Desktop/sage-3.4-linux-Ubuntu_8.10-i686-Linux/local/ lib/sage-flags.txt ********************************************************************** I tried removing this file to see if sage will run correctly, it doesn't seem to. For a quick stress test I did sage: prime_pi(10^10) ... and got back /home/bixbyr/Desktop/sage-3.4-linux-Ubuntu_8.10-i686-Linux/local/bin/ sage-sage: line 197: 8689 Segmentation fault sage-ipython "$@" - i It returns correctly for prime_pi(10^9), so although it's possible that the two errors are unrelated, that seems a strange way to fail if the issue were related to insufficient memory. I downloaded sage-3.4-linux-Ubuntu_8.10-i686-Linux.tar.gz from the University of Washington mirror. I'm running ubuntu 8.10, kernel version 2.6.27-11-generic. I have 4gb of ram, though running a 32 bit kernel effectively limits me to ~3.2 gb. Since sse4 is a cpu instruction set (from what I understand), here it the output for cat / proc/cpuinfo: processor : 0 vendor_id : GenuineIntel cpu family : 6 model : 15 model name : Intel(R) Core(TM)2 Quad CPU Q6600 @ 2.40GHz stepping : 11 cpu MHz : 1600.000 cache size : 4096 KB physical id : 0 siblings : 4 core id : 0 cpu cores : 4 apicid : 0 initial apicid : 0 fdiv_bug : no hlt_bug : no f00f_bug : no coma_bug : no fpu : yes fpu_exception : yes cpuid level : 10 wp : yes flags : fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pat pse36 clflush dts acpi mmx fxsr sse sse2 ss ht tm pbe nx lm constant_tsc arch_perfmon pebs bts pni monitor ds_cpl vmx est tm2 ssse3 cx16 xtpr lahf_lm bogomips : 4799.97 clflush size : 64 power management: ( ... it then lists 3 more processors with the same information) Although not the newest processor, it seems like this should be recent enough to run sage. I also tried installing the new version on my laptop, another ubuntu 8.10 system this time with a core 2 duo processor, and got the exact same error. Any thoughts? Thanks a lot, - Ryan --~--~---------~--~----~------------~-------~--~----~ 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 URLs: http://www.sagemath.org -~----------~----~----~----~------~----~------~--~---
