![]() I don't have access to a Mac machine, but OS X installation files seem to be outdated (the newest one, xcas_osx10_, is from 2019).īy the way, there is a possible bug in tmdoc style. Instructions for Ubuntu installation (using up-to-date deb files) are here: The version on Windows that should be installed (in Windows 10) is the 64-bit version here:Īlso, you can find installation files here:įor Windows one needs xcas64inst.exe, while for Ubuntu giac_1.6.0-xx_b and giac-dbgsym_1.6.0-xx_b are needed (always get the latest version). (But it must be running interactively for that of course.) Note that you can obtain version number by typing "version()" in a giac session. They are annoying nevertheless, I will try to write patches for giac source to set proper doc paths and also print giac version in the banner. The warnings in the session banner should not prevent giac from running. Giac is a great CAS kernel but the existing user interfaces could be better. I'll try to initiate some work on proper icas binaries for Windows. ![]() Could giac be started within cygwin from texmacs somehow? Hence, unfortunately, icas does not run interactively in Windows commandline as for now that's why you managed to start giac but did not get an answer to the "1+1" query. Maybe it would be better if compiled with mingw (or visual studio, but I More precisely it does not work interactively, but it works more or less in batch mode (like in icas 'factor(x**4-1)' > log). "About icas under windows (cygwin), it works if I run it from cygwin bash, but not from windows commandline. I wrote to Bernard Parisse about it and he replied: I managed to replicate the problem on Windows you mention. I can report that giac 1.6.0 runs in texmacs 1.99.15 without problems at my Linux Ubuntu (focal LTS) platform. Just to be clear, giac sends answers to texmacs using Is the above formatting correct? Am I perhaps missing math-mode somewhere? I could easily adjust the formatting in giac. ![]() The answer to a giac session query is formatted as follows: Perhaps this behaviour somehow related to the fact that giac sends answers in texmacs Scheme while other CAS-es typically send latex code. That does not happen with Maxima, for example. Another option that I will try is to create a CLI application within giac plugin for texmacs, which would link to giac.dll (available in the official Xcas installation for Windows).Ībout interactive giac sessions in texmacs 1.99.16 (Ubuntu 20.04): results display as expected in the generic style, but if I switch to tmdoc style i get question marks instead of results. I will soon start working on a Qt version of giac and a new, cross-platform CLI interface. It gets difficult mainly because of FLTK integration which must be enabled to provide graphics features. So I tried to compile giac on Windows 10 using MinGW and Visual Studio but that turned out to be extremely complicated. Unfortunately, I wasn't able to start an interactive giac commandline/cygwin session in windows using the available binaries. ![]()
