I would look over the updated GNV components, particularly the VMS specific source and build procedures.
https://sourceforge.net/projects/gnv/files/ Source repositories (Mercurial) are available at https://sourceforge.net/p/gnv/_list/hg?source=navbar .
The GNV updated modules like coreutils contain wrapper libraries that allow select() and poll() to work with X11.
There are some tricks needed for porting X11 applications to VMS. You will likely need a wrapper to the main() routine.
1. GNV Bash contains the code to set the DISPLAY environment variable that ported X11 programs expect to the VMS default DECWindows display device you created.
2. OpenVMS uses event flags instead of file descriptors for X11. It uses event flags from the free event flag pool. By default only 2 are free. Look those up in the documentation and use dup() to create file descriptors to /dev/null for them to prevent the the application from opening actual files using those file descriptor numbers.
Much of the older ports are assuming an older VMS version than 8.4.
jiml November 09 2018 Thank you , Malmberg ! Exactly what I was hoping for . Reset key & all is well . JImL
malmberg November 09 2018 Eisner was upgraded to the current Multinet Release. As part of that a new host key was generated. The old key was incompatible with newer Linux.
jiml November 02 2018 ssh to eisner is now giving (on linux) "WARNING: REMOTE HOST IDENTIFICATION HAS CHANGED!" , Has the server key in fact changed ?

malmberg December 12 2017 HPE only makes the most current version of OpenVMS Alpha / IA64 /VAX available to hobbyists. When I had access to the Alliance 1 program it was the same. No public downloads are allowed by HPE.
