Aside from just getting stuff linked together (plenty of trouble to start with), the more difficult problem is that Maxima is written with a pervasive assumption that there is someone at the console, e.g you ask for an integral or a limit and Maxima comes back with a question about some parameter. That make interaction with another program very difficult (as I think you know already). I have attempted to resolve this by converting questions into conditional expressions e.g. "Is x positive, negative, or zero?" => if x > 0 then ... elseif x < 0 then ... else .... It sort of works but there are difficulties. If anyone wants to work on it with me, I'd be glad to have the help.
