Adding #include "ccx_encoders_spupng.h" at the top of the file /src/lib_ccx/ocr.c makes it compile for Arch Linux. But I have no Idea why it compiles for debian without the aforementioned Change, as I have tried in both.
Here's what I know, the error doesn't come from CMake
At first I thought it did as paru's version is different and newer than apt's version(3.30.5-1 as compared to 3.28.3-1), but changing it doesn't fix it.

@steel-bucket Can you please mention the version of clang when using debian? I reproduced and got the same results, I think debian might be using an old version of clang and hence does not treat the warning as an error, described as here: https://www.redhat.com/en/blog/new-warnings-and-errors-clang-16

While my arch system was using latest clang version:

❯ clang --version
clang version 18.1.8
Target: x86_64-pc-linux-gnu
Thread model: posix
InstalledDir: /usr/bin

I just tried this on Ubuntu 24.10 and I needed to patch the file, too, even though this is a Debian derivative.

Thanks!
