I'm sorry for stupid question.
The problem solved via compiling texmacs.lisp under maxima and the
corresponding change of tm_maxima.

I also suggest that we have to do this via some automatic way for others
lisp implementation.


After some experience I found that sbcl implementation of maxima is the best for using within texmacs. It seems to me that loading the compiled version of
texmacs.lisp for gcl implementation of maxima gives a small effect.For the large session the responsiveness of texmacs became slow in this case.
best rgds,

Low GCL performance is probably due to not optimal
initial memory settings in GCL (not suitable for
large problems). Please try attached maxima-init.lisp.
