I would like to get gnuplot working on an Alpha 3000-300 with AXP OpenVMS 8.4 - hobbyist installation.

Tried gnuplot 3.4b and got the term type regis to work, but term type X11 crashes.

I built the gnuplot using @buildvms.com after removing the linkopt.vms/share entry.

I have not looked at GNUPLOT yet.

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.

No more VAX hobbyist licenses. Community licenses for Alpha/IA64/X86_64 VMS Software Inc. Commercial VMS software licenses for VAX available from HPE.

Just re-visiting.. No more hobbyist licenses? Is that from vmssoftware.com, no 'community' licenses?

I recall that the disks failed on the public access VMS systems that included Fafner

Anyone know what happened to FAFNER.DYNDS.ORG? I had a hobbyist account here but can longer access the site.

At one time, didn't this web site have a job board? I would love to use my legacy skills one last time in my career.

Eisner, which is currently being moved, got an SSH update and the keys were updated to more modern encryption standards.
