This reply is a bit late, but in case anyone else is wondering: llpp is written in OCaml and uses a simple bash script as a build system. You just build it with

bash build.bash build

For more details, see the package definition used by Arch Linux: https://aur.archlinux.org/cgit/aur.git/tree/PKGBUILD?h=llpp

a small patch needed for the latest mupdf:

@Sfinx What kind of system are you on? On Arch Linux -lz -lmupdf-third are not needed, which might be related to how Arch builds libmupdf. It compiles libmupdf using

USE_SYSTEM_LIBS=yes make shared=yes build=release libs apps

and with that it looks like only -lmupdf is needed for llpp. I assume this is different for your distro? Do you know what libmupdf-third is and what it's needed for?

[Sfinx]

I do not think it is system dependent. I'm using the current mupdf git.

Made this its own issue, thanks for reporting it! Would be great if we can fix it in a way which works for both of us (and everyone else).

BTW: this small patch switches PgUp/PgDown and Space/BackSpace so reading books by Space is now much more comfortable:
