You are using a binary of Sage on a computer that doesn't support the CPU instruction sets for that binary. You will have to build Sage from source or download a different binary. What is the output of cat /proc/cpuinfo on your computer? What is your exact hardware?

Hi, see http://wiki.sagemath.org/faq and search for "illegal instruction". I would guess you are running a binary - or at least upgraded from one.

[sage-support] Error with LinearCode()
I do the following: sage: MS = MatrixSpace(GF(2), 4,7) sage: G = MS([[1,1,1,0,0,0,0], [1,0,0,1,1,0,0], [0,1,0,1,0,1,0], [1,1,0,1,0,0,1]]) sage: C = LinearCode(G) and I get: /home/carlos/sage-3.0.2-ubuntu32-intel-i686-Linux/local/bin/sage-sage: line 348: 1703 Instrucción ilegal python "$@" and then it stops working. I have already upgraded to 3.1.4 and I didn't have that problem before :-s is there a way to solve this or do I have to upgrade again?? --~--~-~--~~~---~--~~ To post to this group, send email to sage-support@googlegroups.com To unsubscribe from this group, send email to [EMAIL PROTECTED] For more options, visit this group at http://groups.google.com/group/sage-support URLs: http://www.sagemath.org -~--~~~~--~~--~--~---
[sage-support] how to change variable in an integral
Hello, how can I change variable in an integral and get the new
integral without evaluating?
I tried
maxima.changevar('integrate(x*exp(x^2),x)','x^2=y', 'y','x')
but the result is just the integral of the function, not
integral(1/2*exp(t),t)
is it possible to get integral in new variable without evaluation this
integral?
thank you
Robert Marik
