If you install EMWM and the goodies from the author's page you can get a very close system. Also, some guy at Nixers.net it's trying to recreate the whole Irix interface under EMWM. https://fastestcode.org/emwm.html https://fastestcode.org/emwm.html Also if you want to program something in Motif: Motif prog. manual https://www.oreilly.com/openbook/motif/vol6a/Vol6a.pdf https://www.oreilly.com/openbook/motif/vol6a/Vol6a.pdf Motif reference manual https://www.ist.co.uk/motif/download/6B/6B_book.pdf https://www.ist.co.uk/motif/download/6B/6B_book.pdf For the X11 books, current X.org manuals are easily found under X.org docs and they will work nealy the same. Now they promote xcb instead of xlib but xlib itself still works. You'll might (not sure) need: - Xmu.pdf XMU, low level - intrinsics.pdf X11 inners, useful to debug X11 stuff - icccm.pdf Basically window manager standards - libXaw.pdf Athena/X11, if you need something lighter than Motif For instance, you can create some MPV frontend with XEmbed and Motif. MPV can be controlled by sending commands to a socket, and creating a GUI for it can be first prototyped with TCL/Tk and then done with MPV.
