Thanks! In fact for SAGE we will desperately need a fast *symbolic* C/C++ library engine (mainly for symbolic manipulation, i.e., exactly the sort of stuff giac already does well, I think -- maxima doesn't offer this really, because communication between Python and maxima is too slow. Anyway, we are definitely considering including a C or C++ library for symbolic computation in SAGE, and giac is high on our list. It's very nice that all giac dependencies (except fltk) are already included with SAGE. Can one build a non-gui version of giac, e.g., just the C++ library, without fltk? -- William --~--~---------~--~----~------------~-------~--~----~ To post to this group, send email to [email protected] To unsubscribe from this group, send email to [EMAIL PROTECTED] For more options, visit this group at http://groups.google.com/group/sage-devel URLs: http://sage.scipy.org/sage/ and http://modular.math.washington.edu/sage/ -~----------~----~----~----~------~----~------~--~---
