Important: You need to flash the firmware of your fingerprint reader first using https://github.com/mpi3d/goodix-fp-dump.

It is not related to the package but can be useful for someone else: it looks like that my laptop has the 90 degrees-rotated sensor because of if I swipe from left to right during enroll then the verify works great (finger also has to be rotated of course)

Thank you, guys!

With the last changes and this article: https://hackmd.io/@0f-sojqTSA6rPUx1QCuZ5A/S1IsezNpt#Requirement I was able to make fingerprint working on Dell Vostro 3500 (27c6:538d).

It often says 'no match' on verify fingerprint but nevertheless it works!

@paulequilibrio thanks for the suggestion! I updated the PKGBUILD file.

Thank you @ricclopez for your comment. I was able to compile and install by adding the following prepare function to the PKGBUILD file:

prepare() {
  sed -i "common_cflags = cc.get_supported_arguments(\[/a \    '-Wno-incompatible-pointer-types'," ${_pkgdirname}/meson.build
}

This compiles and works fine (as far as I can tell) with the error suppressed.

I pulled the unstable branch and added '-Wno-incompatible-pointer-types', to the list in the cc.get_supported_arguments call on line 22 of meson.build

This is the only route I've been able to find to get Goodix 27c6:538d to work.

Hello! Can you help me to build the library? The build failed with

There are also some warnings, I don't know if it is important.

libgudev is missing as a dependency

@guiodic For help regarding your scanner, you best join the Linux Goodix Fingerprint Development discord: https://discord.gg/6xZ6k34Vqg

I have the 531d, I found on https://github.com/mpi3d/goodix-fp-dump. a file for 53xd, maybe it works on my fingerprint scanner? But I did not understand how to use goodix-fp-dump to flash the figerprint scanner
