I have no understanding of the internals, and I'm no programmer (except for simple functions), but in the immediate instance would it not be convenient to have a list of instructions for the user (such as me) to install fricas/jupyter with all the correct libraries on their system? As I discovered, Ubuntu 14.04 does not automatically install the required zmq libraries; these had to be installed by downloading the source files for zeromq-4.0.5 and compiling them. Maybe a bit later this could be done using the GNU autotools: autoconf, automake etc, about which I know less than nothing. I envisage the user downloading the iSPAD source, and then "make" runs a configure script, downloads and installs all the required libraries, and you're good to go!
What we need is more tame graduate students... in fact I'm in the position (not until March next year now), of putting up final year capstone projects for our computing students. If you have any FriCAS projects, which are computing based rather than mathematics based, let me know! -Alasdair On Tuesday, 13 October 2015 11:29:56 UTC+11, Waldek Hebisch wrote: > > Kurt Pagani wrote: > > > > > > > > Am 12.10.2015 um 01:12 schrieb Waldek Hebisch: > > > > >> FriCAS/Axiom graphics requires an X server and that would be very > > >> awkward to include in a Jupyter kernel. > > > > > > Actually in principle graphics routines could be easily > > > retargeted.
