Hi, I'm experiencing instruction set issues with the SAGe Linux i686 binary tarball from
http://mirror.switch.ch/mirror/sagemath/linux/32bit/\ sage-4.1.1-linux-Debian_GNU_Linux_5.0_lenny-i686-Linux.tar.gz I've checked on two different platforms which have an almost identical Debian/Lenny installation: an Athlon-XP <athlon> and a Pentium-M <pentium>. (Platform details: see below, if more information is needed I'll be happy to provide.) Compiling entirely from source worked for <athlon>, but I didn't try full source compilation on <pentium>. After extracting the binary tarball, startup of SAGe yields: <athlon> -------------------------------------------------------------------- | Sage Version 4.1.1, Release Date: 2009-08-14 | | Type notebook() for the GUI, and license() for information. | -------------------------------------------------------------------- ********************************************************************** WARNING!

This was, however, not a problem when compiling from source on <athlon>. I did not dive further into this problem since the source compilation worked for me. As a bottomline, I would wish for a clear statement placed at some prominent place on the website giving a hint about which CPU attributes (instruction subsets) are needed to run the precompiled binaries. As for me, I was expecting a *-i686-Package to run on anything from Pentium-II upwards (at least, I did not expect an issue like this on an Athlon-XP or a Pentium-M).
