[sage-support] Re: Failure running sage-vmware-sse2-3.4.1
1. Was this the type of CPU that this binary was supposed to work for (having sse2 and not sse3)? 2. Is Sage migrating to work on only modern duel core CPUs? I have compiled Sage 3.4 on an older processor Ubuntu linux notebook and it worked. Is this going away? 3. Can I compile Sage using a vmware player or do I need to upgrade vmware to compile Sage? 4. Can start from the failed installation of sage-vmware-sse2-3.4.1 and do a native compile? 5. Can I do sudo apt-get install of the software components I need to compile Sage in vmware? It seems some of us using windows XP are locked out of using Sage 3.4, but we don't understand what the road block is.

William, Thanks I was able to compile sage 3.4.1 on my XP machine starting from sage-vmware-sse2-3.4.1, which had failed work from the binary, by following your directions. For people that might know even less about linux than me the steps I took were: At the login type: login The Passward is: sage then type: sudo su 1. Just delete /usr/local/sage, then cd /usr/local; rm -rf sage 2. download sage-3.4.1.tar by typing wget http://sagemath.org/src/sage-3.4.1.tar 3. extract it, tar xvf sage-3.4.1.tar 4. move it to be /usr/local/sage, and mv sage-3.4.1 sage 5. type make. cd sage; make Thanks Mike On Apr 30, 2:34 pm, mabshoff michael.absh...@mathematik.uni- dortmund.de wrote: On Apr 30, 10:53 am, William Stein wst...@gmail.com wrote: On Thu, Apr 30, 2009 at 10:43 AM, Iwan Lappo-Danilewski ivanjazz...@gmail.com wrote: Have to report a similar problem on ubuntu 9.04..

Can't still find any decent tool for sharing objects. Saving and

You can already do this. In a worksheet, just do
save(a,'a.sobj')
then publish the worksheet that contains a, then there will be a link
to the sobj.
E.g., I just published http://sagenb.org/home/pub/505/ which contains
such a link:
http://sagenb.org/home/pub/505/cells/2/a.sobj
Now anybody can do:

Ah, yes, you can. I still think it might be handy to be able to just
publish objects detached from worksheets though. Taken one step
further, being able to push them too to a public place (though
this opens a whole can of authentication/security issues).
