solve() doesn't solve some system solvable by (standalone) Maxima's solve()

[EmmanuelCharpentier]

Short story : Sage's solve(), which uses Maxima's solve() doesn't solve some systems solvable by Maxima's solve when used standalone.

See the long story and an example in this sage-support post.

The prime suspects are the initializations we use to set Maxima up for use with sage. I already tried to set domain to real (which is the default when Maxima is used standalone, whereas we use complex with Sage), to no avail.

Did you try with the latest Maxima (5.41)?

(It's probably time to upgrade Sage's Maxima anyway...)

Replying to @dimpase:

Nope : I have only 5.40 (as packaged by Debian), and Debian is late packaging 5.41...

But my point is that our Maxima (5.39), invoked from the command line, is able to get a solution. The problem lies in our way to call Maxima's solve() from a Sage session.

(It's probably time to upgrade Sage's Maxima anyway...)

Indeed. Isq that complicated ? I saw a message announcing an (your ?) intention to package it, but didn't saw a related ticket (I didn't look specifically for that, so I may have missed it).
