maxima.el doesnt work. Why?



Hi,

I'm trying to make MAXIMA work in my Emacs 21.3

I installed the el files come with maxima 5.9.0 and loaded
maxima.el successfully. I started maxima-mode and I can see
the correct font lock.

But if I instruct it to eval a line with C-c C-c, Emacs
says:

"Symbol's value as variable is void: comint-output-filter-functions"

Why does this happen?


I also try to use imaxima, but it doesn't output graphics. I
see the following screen:

This is a development version of Maxima. The function
bug_report()
provides bug reporting information.
^C(C1) ^Dintegrate(x^2,x);

^B ^D1^W\ifracn{x^{3}}{3}^E
^C(C2) ^D

I have a well configured TeX system and I installed the sty
files with imaxima and breqn correctly.

They just don't work.
I hope you can help me.
Thanks.
