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.
