[ Description ]
Downloading the latest PKGBUILD for this package from the official Arch Linux GitLab page & running "makepkg -si" in the directory it is downloaded to consistently leads to compilation errors & the package not being built.

[ Additional info ]
Same result whether its on my main system with custom config or a freshly installed system with 100 percent default configuration for everything.
I did not edit the PKGBUILD. Errors occur with the provided PKGBUILD.
I even tried cloning the official GitHub repo for xreader & manually running the commands contained within the PKGBUILD on the cloned repo, same exact errors.
The errors start after the "[355/361] Linking target libview/libxreaderview.so.3.0.0" line
I have base-devel installed & installed packages are fully up to date.

[ Steps to reproduce ]
git clone https://gitlab.archlinux.org/archlinux/packaging/packages/xreader
cd xreader
makepkg -si
(proceeds to fail to build no matter what I do, custom or default config, new or old Arch Linux installation)
