Problem by running



Hallo Stavros,

thanks for your reply.

The running of my Mxima codes on Unix is without problem, which Lisp
implementation type is SBCL.

I think, the problem is what Robert explained about GCL.

I will try to recompile Maxima via the Lisp program ASDF but I am
waiting for the answer of Robert.

Best regards

Sara


you are interested.
