Fricas is an experimental Sage package. Just do ./sage -i fricas Assuming that your ./sage is in good shape (say, compiled from source), you'll be all set. , and I remember a while back having multiple issues getting FriCAS > installed on a Gentoo machine. > > Maxie > > On Saturday, November 19, 2016 at 1:50:32 PM UTC-6, David Roe wrote: >> >> >> >> On Sat, Nov 19, 2016 at 2:40 PM, Thierry <sage-goo...@lma.metelu.net> >> wrote: >> >>> On Sat, Nov 19, 2016 at 02:31:42PM -0500, David Roe wrote: >>> > Another thing that might be nice to tie in is the Online Encyclopedia >>> of >>> > Integer Sequences.
