linux-gpib-installer compiles and installs GPIB/VISA using open source drivers from the linux-gpib project.
It is an automated implementation of the instructions by jonathanschilling which install drogenlied/linux-gpib-dkms.
Currently only¹ Debian 11 (aka Bullseye) is supported.
Automatic /etc/gpib.conf configuration is done for the National Instruments GPIB-USB-HS USB dongle, if you are using a PCI card (after following the instructions below), see /etc/gpib.conf.example and make the appropriate changes to /etc/gpib.conf.
