Hi all,
I'm trying to make some changes to my sage installation. I change the
file in the $SAGE_ROOT/devel tree, then call $SAGE_ROOT/sage -b
Now this works on my laptop, but not on my desktop. If I run
$SAGE_ROOT/sage, it's as if I made no changes at all.
This is an example of the output from "sage -b":
...
running build_py
copying sage/rings/polynomial/multi_polynomial_ideal.py ->
build/lib.linux-i686-2.5/sage/rings/polynomial
running build_ext
running build_scripts
running install_lib
copying build/lib.linux-i686-2.5/sage/rings/polynomial/
multi_polynomial_ideal.py -> /home/software/sage-3.2.1/local/lib/
python2.5/site-packages/sage/rings/polynomial
byte-compiling /home/software/sage-3.2.1/local/lib/python2.5/site-
packages/sage/rings/polynomial/multi_polynomial_ideal.py to
multi_polynomial_ideal.pyc
running install_scripts
...
Here's the relevant change in the devel tree:
for i in range(M.ncols()):
if int(singular.eval("%s[1,%s+1]!=0"%(M.name
(),i))):
(lines 1246--1247)
The changes appear in the correct place in the local/lib tree. When I
run sage, however, and type I.basis_is_groebner?? to look at the
source code, I see
for i in range(M.nrows()):
if int(singular.eval("%s[1][%s+1]!=0"%(M.name
(),i))):
Does anyone have an idea why this doesn't take?
regards
john perry
