This new X11R6 are not simply an upgrade of the servers to the latest ones. It is a new programming platform in your DG/ux system to allow you to import all this *FREE* or not software for the X window system. This software will not compile in the old (and ungly) X11 of Data General. The imake command that is implemented in almost all the (source) software for X11 (free or not) will not work with the totally broken "imake" command of /usr/opt/X11 of DG/ux.
The imake of DG/ux X11R5 is badly broken: I have seen DG/ux releases R4.11,MU01, ...MU04, R420, R4.20MU02 ,R4.20MU03 and nobody bother to look in all these releases the imake command...
While until now DG was rather hostile to the prospect of a new X11 in DG/ux some new folks there they have turn their interest in X11R6 (XFree86) these days. That is good of cource because the ultimate target is to make XFree86 (3.3.5 or whatever version) to run in _their_ DG/ux Unix! I will be able to make a much better X11 in DG/ux if I could had some access to DG/ux sources (i.e. the original R5 sources , but not only --eg kernel driver sources as for examble the DG/ux kernel console driver sources).
I have compile almost anything that runs for Linux in DG/ux using this X11. In doing this work in XFree86 I would like to express my thanks to David Dawes that he help me all the time with several techical questions. Also D.T. is one of the people that offer valuable help. Finally I want to express my thanks to John H. for enlight me in some syscall issues.
