Much of above happens in separate processes. In FRICASsys the
expression is supposed to come to 'parseAndEvalToHypertex' which
calls 'parseAndEvalToStringEqNum'. So one thing to check is
starting FRICASsys and trying
)boot parseAndEvalToStringEqNum('"differentiate(sin(x) * exp(x^2),x)")
This should give something like:
(EVAL-WHEN (:EXECUTE :LOAD-TOPLEVEL)
(PROG ()
(RETURN
(|parseAndEvalToStringEqNum| "differentiate(sin(x) * exp(x^2),x)"))))
Value = (" 2 2"
" x x"
" (1) 2 x %e sin(x) + cos(x)%e"
" Type:
Expression(Integer)")
If the above works OK, then possible reason could be is socket code
(data have to go trough sockets before it gets to
'parseAndEvalToHypertex')
