For the hell of it, I tried this installer on a "spare" Windows VM.
Bravo, bravissimo ! Now, there might be some use to all those Windows boxes... I tried to install some optional package ; it turns out that the installed setup isindeed minimal : (sage-sh) charpent@DESKTOP-P0B7HOE:~$ time ( for i in database_gap dot2tex giac giacpy_sage ; do sage -i $i ; done ) /opt/sagemath-7.4/src/bin/sage: ligne 302: make : commande introuvable /opt/sagemath-7.4/src/bin/sage: ligne 302: make : commande introuvable /opt/sagemath-7.4/src/bin/sage: ligne 302: make : commande introuvable /opt/sagemath-7.4/src/bin/sage: ligne 302: make : commande introuvable Either that or the necessary utilities are out of Sage-subshell's reach. A bit of Windows-specific documentation is needed. A (relatively) inexperienced user should not have to struggle to find : - How to open a cygwin console (as opposed to a Sage subshell) in the setup created by the installer. - What (and how) to install in order to install optional packages. - What (and how) to install in order to recompile (e. g. testing a git branch). - A pointer to Cygwin docs. - Advice about what should be installed under cygwin and what should be installed outside (e. g. emacs, TeX, various Unix-like tools). - Advice about how to use Sage-installed programs outside of Sage (e. g. Maxima, lisp, Python, etc...). I'll play a bit more with that setup (and, of course, report errors an quirks). But my first impression is that it *is* a vast improvement over the VM solution.
