[sage-support] Re: again problem with plotting
I tried to compile Sage from source, but it ran out of memory compiling linbox. Is there a workaround?

Unfortunately not. gcc is an absolute pig when instantiating templates and with LinBox you need anywhere from 350 to 700MB memory. You can add swap space which will make the compilation work, but slow it down by quiet a lot, i.e. I have build LinBox on a G4 with 256 MB physical RAM, it just took a while. Which hardware are you using?

line 215: 21171 Illegal instruction sage-ipython $@ -c
$SAGE_STARTUP_COMMAND;
The error message Illegal instruction means that you are using
a binary install of Sage that was built on a computer whose processor
has instructions that your computer's processor doesn't have.
You will likely have to build from source, or wait for somebody
to provide a binary for you that works on your hardware.
A few days ago I got an older Pentium M thinkpad fix, and once I install
Ubuntu Linux on it, I could likely use it to build a binary that will work
for you. Last time I tried to build Sage on it, the fan in the laptop died!
So I had to get that fixed, which I've now done.

Note: the only thing I did before was to try SymPy, since I wanted to try
out
it's plotting capabilities. Now, I'm lucky and have the complete history
still
on my screen, find it below.
Help would be very much appreciated.
Is it a no no to import SymPy?
