Build Fails, Poppler 24.01.0-1 Arch

[SuperContraptionGuy]

Just wanted to pop in and express interest in this project. Does anyone know of an alternative multi-threaded pdf viewer?

Followed the build commands listed in https://aur.archlinux.org/cgit/aur.git/tree/PKGBUILD?h=flaxpdf-git

$ git clone https://github.com/clbr/flaxpdf
$ cd flaxpdf
$ ./autogen.sh
$ CC=gcc CXX=g++ ./configure --prefix=/usr
$ make

Resulting in make errors:
