Introduction

libfprint for cs9711 using https://github.com/ddlsmurf/libfprint-CS9711 patches
and https://github.com/archeYR/libfprint-CS9711 patches
on top of official upstream https://gitlab.freedesktop.org/libfprint/libfprint
with sigfm branch merge from https://gitlab.freedesktop.org/Tooniis/libfprint.git
PKGBUILD is based on https://gitlab.archlinux.org/archlinux/packaging/packages/libfprint
and https://aur.archlinux.org/packages/libfprint-cs9711 adapted for current usage.

Notice

Test is disabled as the build can't pass it and always failed. If anyone know how to correctly deal with it, please comment.

This package is currently broken due to its patch-based build approach. The underlying issue is architectural: the PKGBUILD layers ddlsmurf's patches and archeYR's patches on top of stock upstream libfprint rather than using an integrated fork, making it inherently fragile against upstream changes.

I'd recommend switching to libfprint-cs9711-rebase-git instead. It clones archeYR's cs9711-rebase branch directly, where the CS9711 driver code lives as proper git commits that are regularly rebased onto new upstream libfprint releases — no fragile patch files, and enrolled fingerprints carry over on upgrade.

New upstream for (patches for) this is https://github.com/archeYR/libfprint-CS9711

@lemagex I would probably not want to remove patch 4 tbh. Yeah it generates some patch warnings, but those aren't that important, but what it does is changes some communication behaviors to match Windows's, so it might not be the best idea to ignore it.

You can hang the hardware given the right circumstances if you don't give it the right sequence of commands, basically.

Patch 6 is fully replaced so it's safe to just be tossed.

If you want this to just install, I removed 004 and 006, and it was fine.

I changed

for patch in $srcdir/*.patch; do
    git apply $patch
  done

in pkgbuild and replaced with

  for patch in $srcdir/0000-*.patch $srcdir/0001-*.patch $srcdir/0002-*.patch $srcdir/0003-*.patch $srcdir/0005-*.patch; do
    if [ -f "$patch" ]; then
      git apply $patch || echo "Warning: $patch failed to apply"
    fi
  done

then removed the files

rm -f src/0004-Changes-derived-from-RE-Windows-driver.patch
rm -f src/0006-Fix-introspection-failures.patch

and

rm -rf src build pkg
makepkg -rsi --skipinteg

and it finally built and worked for me.

Hey @ohaiibuzzle, can confirm. Your modification works, thank you.

I checked the patches and it seems like the only one failing is 0006-Fix-introspection-failures.patch due to changed APIs in the upstream sigfm branch. If you exclude that patch out of the build it runs to completion. I've not yet verify if the device will then work as intended (but in theory it shouldn't change anything regarding image matching?)

Edit: so far so good. Appears that removing patch 0006 is all that is needed for the package to work again. Here's the modifications I made

I've read comments here about clearing the yay package cache, but that hasn't worked for me. I'm unable to build the updated package:

Hope a fix is on the way... thanks!
