[comp.sys.dec] VMS X server ?/ X11R4 ?

muswick@vs2.uh.cwru.edu (03/23/91)

I need some help with some VMS - X server questions.

1. I recently purchased the X-Window System books from O'Reilly & Assoc.  They
are great and I have downloaded the examples.  But one problem is that they
are written for R4, not R3 of DECWindows.  I'd love to make use of these
examples and widgets.  
  
a. When will X11R4 be available from DEC?  (for VMS)

b. I have downlowned sources for R4 but there does not seem to be any VMS
   command or mms files, nor any SERVER OS routines for VMS.  Is there
   someone that has built R4 on VMS and how may I obtain the sources.

2. We would like to add extensions to the server for imaging and for a PIXAR
(Vicom P2) image processing system.  In fact our design approach is similar
to the XIE design Specs.  Problem is that the AddXExtension etc. do not seem
to be available in VMS DECWindows.  They are not documented in the VMS
DECWindows Manual sets, nor are the necessary .h files present.

a. Has anyone added extensions to VMS DECWindows server?

b. A more basic question on extending the server - Is it necessary to recompile
/relink the server to add extensions or can the extensions be a separate .exe
and execute as it's own process and use the some communication protocol with
the X-core server?
