Hi,
yesterday I posted a question
<http://groups.google.com/group/sage-support/t/b388b6c45a7d535f>
regarding QEPCAD uses under Sage. Since it seems that I did not explain
the issue, I'm trying again:
I would like to use QEPCAD in sagecell: Sending
var('a,b,c,d,x,y,z')
qf = qepcad_formula
ellipse = 3*x^2 + 2*x*y + y^2 - x + y - 7
F = qf.exists(y, ellipse == 0)
qepcad(F)
to sagecell I get an error:
OSError: [Errno 13] Permission denied:
'/home/sageserver/sage/local/share/sage/ext/QEPCAD/'
Right now, qepcad is not installed on the sage cell server. I'm trying
to install it now.
