I have tried the AUR package and get the same exact behavior of empty output in my kitty terminal. What terminal are you using?
Fbpdf won't work, if X is running.

When X11 or Wayland is using the graphics card via DRM, the framebuffer device does not work.

This seems like a linking problem (the program being linked with one version of the library and executed with another).

Could you please provide the minimal cc command required to compile and link fbpdf directly without make, which includes specific flags and dependencies?
This seems like a linking problem (the program being linked with one version of the library and executed with another).
I removed some dependencies and compiled each object file and am incurring a previous issue in earlier attempts to install the program.

The Makefile itself includes commands for building and linking fbpdf. I suggest keeping only one version of the mupdf library and removing the other, before building fbpdf.

When X11 or Wayland is using the graphics card via DRM, the framebuffer device does not work.
Oh I'm sorry, I didn't understand that framebuffer applications are designed to run in a real TTY, I can run fbpdf outside of GDM with control+alt+F3.
I initially was interested in fbpdf with mupdf because I thought it would be a bit easier to work with digital books quickly from within a kitty terminal in my desktop environment. I asked a chatbot, it suggest I'd want to use xvfb but want to know if that's right or what you'd recommend if you have suggestions.
Thanks
