G'day,
This compiles just fine but core dumps on run.
journalctl -xe shows this....

What version of gtk4 do you have? I don't have an Ubuntu setup to test and RPI-OS is currently only at 4.8.

Host is Ubuntu on a PC not a Pi.

timt@radiopc:~/Downloads/GPIB/VK2BEA/HPGL-Plotter-main$ gtk4-launch --version
4.14.2
timt@radiopc:~/Downloads/GPIB/VK2BEA/HPGL-Plotter-main$

Also during compilation I see this complaint...

In file included from parseHPGL.c:26:
../include/HPGLplotter.h:237:10: note: ‘#pragma message: You should update to a newer version of linux-gpib’
  237 |  #pragma message "You should update to a newer version of linux-gpib"
      |          ^~~~~~~

But my version is the latest at 4.3.6
