[sage-support] Re: Bug in genus of an ideal
The fact that the number of singularities quoted is precisely 2^32-1 makes me suspect a faulty return fo -1 from somewhere.

[sage-support] Re: Specializing a base ring
This is exactly the problem that the patch here solves: http://trac.sagemath.org/sage_trac/ticket/8807 It's evidently not in Sage yet though. So you *have* to try it out and report on that ticket. -- William Note that #8807 very nearly got a positive review (from me) but there were some trivial issues, and then the patch author (Simon King) moved house and has not had time to fix them yet.

[sage-support] SageTeX encoding issue?
Hi everyone,
I've toyed a bit with SageTeX now that it supports XeLaTeX (that's
really nice), and stumbled on some encoding problem, when I try to use
french accentuation in comments.
For example, this works as intended:
\begin{sagecommandline}
sage: # This is a comment
sage: 2+2
\end{sagecommandline}
But as soon as a try to use french accents (é è à ô ë, etc.) it fails:
\begin{sagecommandline}
sage: # à â ô é ù ï ë ö
\end{sagecommandline}
When running sage on this, I will get:
SyntaxError: Non-ASCII character '\xc3' in file test.sagetex.py on
line 20, but no encoding declared; see http://www.python.org/peps/pep-0263.html
for details.
Following that link to Python's pep-0263, I tried adding something
like # encoding=utf-8 at the head of the file test.sagetex.sagetex,
but the error persisted.
This does not only happens in the sagecommandline environment, but
also in sageblock, in any of Sagetex's environment, I would believe.
Sage's notebook works fine, as is Sage in command line (tested with
comments: # é à ô ù).
Any ideas?
Thanks.

[sage-support] the experimental wxpython package
I am using an asus EEE1000 (Intel atom), 32 bit with Ubuntu 110.10, Maverick Meercat I edited the file /media/sage/sage-4.6-linux-32bit-ubuntu_10.04_lts-i686-Linux/local/lib/ pkgconfig/libpng.pc since SAGE_ROOT was defined twice and while installing it complained about that. I installed the packages libglu1-mesa-dev libgl1-mesa-dev libgtk2.0-dev libwxgtk2.8-dev and their dependencies. But after compiling for a while it gave the error message: In file included from ../include/wx/gsocket.h:179, from ../src/gtk/gsockgtk.cpp:21: ../include/wx/unix/gsockunx.h:40: error: using typedef-name ‘GSocket’ after ‘class’ /usr/include/glib-2.0/gio/giotypes.h:132: error: ‘GSocket’ has a previous declaration here ../src/gtk/gsockgtk.cpp: In function ‘void _GSocket_GDK_Input(void*, gint, GdkInputCondition)’: ../src/gtk/gsockgtk.cpp:34: error: ‘struct _GSocket’ has no member named ‘Detected_Read’ Any ideas how to make the experimental package compile or have sage use the wxpython that I have in my system? -- To post to this group, send email to sage-support@googlegroups.com To unsubscribe from this group, send email to sage-support+unsubscr...@googlegroups.com For more options, visit this group at http://groups.google.com/group/sage-support URL: http://www.sagemath.org
