{{{
I've just downloaded and launched Sage on an Ubuntu 8.10 box. I
unzipped the file and ran ./sage and got this:
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:
nx up
I downloaded this image of Sage:
sage-3.2-ubuntu32bit-intel-i686-Linux.tar.gz
Is there anything I can do?
Thanks in advance
Jeffrey
}}}
The problem is that nx for example is a no execute flag and has zero
impact on compatibility for binaries. We should only trac sse, sse2 and
see3 flags (and potentially others, but I will do some research here.
Cheers,
Michael
