Hello,
I put it here just in case.
This week-end I added support for Windows to my copy of FriCAS [1], it is not a concurrent I insist, it's a parallel work in progress not destined to create a standalone package. And using the amazing work of Qian, here on workflows, I was able to build FriCAS with libjulia.dll dynamically loaded. His work, and others of course, helped me to build FriCAS on MSYS2/MinGW with support from Julia. It includes the ability to produce graphics without X. Personally I use WSL2 and do not extensively use graphics but in case of material incompatibility for example this could be of help to others. I hesitated to post a screenshot, not a big fan in a mailing list, but this is for Windows which uses, intensively, human/machine interface in a graphical manner. I think that could be of interest to pure Windows users. I will eventually produce a binary installer and release it on GitHub, I first need to look at license concerns. If I do it, I might eventually produce a Windows binary installer for the official FriCAS if there are some interest. On Windows this is the preferred way to install software.

PS: hoping the screenshot is not too large...
