sage-9.2-r1, ecls-20.4.24-r2, maxima-5.44.0: Module error: Don't know how to REQUIRE MAXIMA. #613

Closed g-regex closed 3 years ago

Hello!

I have recently updated Sage to version 9.2. This also required updating to maxima-5.44.0 and to ecls-20.4.24-r2.

The problem I am encountering now is that functions, which use Maxima, cannot be executed anymore, while the following error is reported:

RuntimeError: ECL says: Module error: Don't know how to REQUIRE MAXIMA.

I have seen that there is another open issue with ECL, but this one seems to be a bit different.

As suggested in that thread, I have tried the following to find the source of the problem:

sage: from sage.libs.ecl import ecl_eval
sage: ecl_eval("(require 'maxima)")
---------------------------------------------------------------------------
RuntimeError                              Traceback (most recent call last)

    341     else:

RuntimeError: ECL says: Module error: Don't know how to REQUIRE MAXIMA.

Trying to require Maxima directly in the ECL REPL gives the same result:

> (require 'maxima)

Condition of type: SIMPLE-ERROR
Module error: Don't know how to REQUIRE MAXIMA.

On trac.sagemath.org I could not find anything related to this and since nobody else opened an issue about this yet, I assume the problem lies somewhere with my personal setup.

Any ideas, where I can continue looking for the problem?

You need the maxima from the sage-on-gentoo overlay which should have the fix for this. It should be enabled by sage-9.2 keyword file.

Thank you very much! This solved the issue.
