2009-03-06 Thread Alex Lara

Sagetex is working!!! (and also Maxima).

I did the following:

I found that LANG=ex_MX.UTF-8 but .bashrc had
export LC_ALL=C. So I commented and run
sudo dpkg-reconfigure locales

After that Maxima start to works.

Thanks for the support.

I;'m pretty sure ECL will exhibit some variation on Clisp's behavior,
for better or worse.

Many thanks for the workarounds above!  We may be able to at least
automate them for Sage, which would be a step forward.

That said -- I'm really looking forward to Sage switching to Maxima + ECL.

Try this: change the environment variable LC_CTYPE
e.g. LC_CTYPE=ES_es or LC_CTYPE=ES_es.UTF-8 or something
like that. Or maybe somehow indicated ISO 8859-1 or Latin-1 or
something. Then Clisp might know how to decode the offending bytes.

Another tactic: put the following in your $HOME/.clisprc file.

  (format t "HELLO FROM CLISPRC~%")
  (ignore-errors
(progn (setf custom:*default-file-encoding*
 (ext:make-encoding :input-error-action #\?))
   (setf custom:*terminal-encoding*
 custom:*default-file-encoding*)))

That replaces undecodable bytes by '?' characters.
(The "hello" message is just to verify the code is loaded )

The bad news is that it's not exactly a Clisp idiosyncrasy.
Clisp is trying to "do the right thing" when faced with undecodable
bytes.
Unfortunately the Common Lisp spec, while it recognizes the
existence of character encoding issues, doesn't specify what to do
when a byte can't be decoded to a character. Other Lisp
implementations
probably have their own ways to handle it.

That could also be exactly what Dan and I said -- a funny filename character
issue, which you don't see was root since root has different files in root's

Hi there,

I suppose it has to be with permissions. Sage is installed at my home
directory. If a run sage as a root (su and then ./sage) maxima
works!!! But if only run sage with sudo ./sage it does'nt.

Do you have an idea why is that?

That's a good guess.  There is a known major bug in Maxima + clisp where
it totally fails to work if there are certain non-ascii characters in the
filenames in the current directory or PATH.  I can't wait until clisp isn't
in Sage.

I am totally guessing here, but is there a non-ascii character somewhere

I'm not quite sure what to do, but an obvious first step is to try
reinstalling the Maxima spkg. Try

  sage -f http://sagemath.org/packages/standard/maxima-5.16.3.spkg

and see if that fixes things.

Hi Dan,
You are totally right. The problem is that Sage can't start maxima.
Here is part of the output when I typed

sage: var('x k w')
(x, k, w)
sage: f = x^3 * e^(k*x) * sin(w*x); f
---
RuntimeError  Traceback (most recent call

So, I guess I need to fix this first (how I don't know). right?

He not only reads sage-support, but occasionally refers to himself in
