Hallo Peter, axiom-mail@nongnu.org is the Mailing list for AXIOM, not FriCAS. FriCAS is a different project (a fork of AXIOM) with mailing list <fricas-de...@googlegroups.com> .

No idea what a viewport manager is. Where to get it? > With friendly greetings, > Peter Probably what I say here applies to both Axiom and FriCAS. If you start FriCAS via the 'fricas' script, then (depending on how you have compiled FriCAS and what resources are available) it will spawn a few processes, among them is HyperDoc, a viewport manager, and the actual FriCAS process (still called AXIOMsys). All this is managed by a super process (called s(uper)man). In your case, the AXIOMsys process computes the graphics and wants to transmit it to the viewport manager (an engine that displays the data and lets you interactively work with it). I suspect, that something went wrong with your compilation (graphics has been turned off for some reason by the ./configure run. Without looking at the log files, I cannot say. Please send your config.log to fricas-devel. Anything that you think might be helpful to solve your problem is welcome.
