Looks like you have a very old maxima version.
The plugin sets the lisp compiler to sbcl (Steel Bank Common Lisp) because that can handle unicode strings in contrast to CLISP.
Older versions can't handle this.
Possibly this can be an issue.
Normally there should be no reason for messing with maxima.xml except you want to implement custom translations.
If the path shown was stored from the settings dialog, then this should not be the problem.

So please install the newest official release of Maxima and retry.

Thanks,
I only took the xml extract to show my data.
I wrote a bib for wxmaxima a few years ago about analytical geometry (what's the technical term in English) - the maxima installation comes from it - I will update it.

I didn't get very far on this topic with SMath alone.
BTW: do I need a plugin for at() (chapter 6.6.5)?
The function list shows nothing...

Danke,
Den xml-Auszug hab ich nur genommen, um meine Daten anzugeben.
Ich hab für wxmaxima vor einigen Jahren eine Bib zur analytischen Geometrie (wie heißt der Fachausdruck in English) geschrieben - die maxima Installation stammt daher - werde ich updaten.

Zu dem Thema bin ich mit SMath alleine nicht weit gekommen.
BTW: braucht man für at() (Kap 6.6.5) ein Plugin?
Die Funktionlist zeigt nix an...

Yes, it is from custom functions (definition) and custom glyphs (formatting). The handbuch assumes that you install the preconfigured distribution with plugins already on board, see section 2.2.
Therefore usually the dependencies aren't listed. You can also use the interactive handbook, which will ask for downloading the appropriate plugins upon use.

BTW, when trying to run the COMA library (controller optimization with maxima) then the major problem was how to tell the wxplot functions to output image files in a given resolution with a given format and name.
Any idea about that?

Ok, Danke dafür...

About COMA
I am for sure you have contact to Mario Riotorto?
We had a lot of discussion to my project ( er liest ja ganz gut Deutsch und spricht gut Englich ;-)
He maintains Maxima-Gnuplot/VTK interface and when he has no idea...?


BTW:
what about the 3D Axes seems to show not the right hand

There are 24 ways of representing XYZ system.
Mathcad up to MCD 11 is ≠ Mathematica 4.0
Have you tried Geogebra from Steen Groode [former Mathsoft collaboratory].

As to COMA, some years ago I had some discussion with Wilhelm Haager, who pointed me to some bug fixing in the draw package. There was some subsequent discussion in the maxima user list. For me, having COMA working under SMath was kind of nice to have, so I didn't keep track on that. Whenever I'll have time for substantial work on the Maxima plugin (would include getting used to VS and C# again), the focus would be on bug fixing and refactoring for better maintainability.
I never really went into the details of the draw package. Thank you for pointing me to Mario, in fact, I never had contact with him (there was another Mario in the maxima list...).

As to 3D axes, see section G.4 in the appendix of the handbook. Built-in 3D plot has several bugs, leftiness of the triade is just one of them.

1. Can't find appendix G.4 from today download
2. What is triade bug ?
........................

1. Native Smath 3D surface plot does not save settings,
reported, not attended, forget for ever.
2. Native Smath 3D [from CreateMesh] missing axes set-up
or alternately display as plotted axes system, for reproducible.

1. I refer to this handbook.
2. The co-ordinate axes (indicated by a triade of lines) are left-handed.
