@FalsePerspective the packages fprintd-vfs_proprietary and libfprint-vfs_proprietary-git do not support your device. You should install libfprint and fprintd packages which are on the official Arch Repositories

According to the documentation, my fingerprint reader is supported by libfprint

[  637.060251] usb 1-1: New USB device found, idVendor=04f3, idProduct=0c26, bcdDevice= 1.40
[  637.060258] usb 1-1: New USB device strings: Mfr=1, Product=2, SerialNumber=0
[  637.060262] usb 1-1: Product: ELAN:Fingerprint

However, after I start the service, it can't find my device:

$ fprintd-enroll
list_devices failed: No devices available

Thanks @kapcom01. We are at the same point.

I need to restart frintd daemon, wait ~40s and then use fprintd-{whatever}. I am able to enroll, but not to verify:

Using device /net/reactivated/Fprint/Device/0
Listing enrolled fingers:
 - #0: right-index-finger
Verify result: verify-no-match (done)

Keep debugging...

@kermitaln: run sudo systemctl restart fprintd.service, watch sudo journalctl -f -u fprintd and wait for systemd[1]: fprintd.service: Succeeded. to appear (about 40 seconds later)

Then you may be able to run (without timeouts) fprintd-enroll and another 40 seconds later fprintd-verify. For me this worked but I get Verify result: verify-no-match (done) every time I try to verify any fingerprint.. Something is wrong..

Same behavior, yes.

Each call to fprintd-{whatever} prints:

systemd[1]: Starting Fingerprint Authentication Daemon...
systemd[1]: Started Fingerprint Authentication Daemon.
(and after a while...)
systemd[1]: fprintd.service: Succeeded.

I also get timeouts when enrolling:

❯ fprintd-enroll
Using device /net/reactivated/Fprint/Device/0
Enrolling right-index-finger finger.
EnrollStart failed: Did not receive a reply. Possible causes include: the remote application did not send a reply, the message bus security policy blocked the reply, the reply timeout expired, or the network connection was broken.

EDIT: I uploaded a workaround and now you can successfully install the package.

But for me this was not enough.. Maybe you have better luck on your system.

Unfortunately the best result I could get was to enroll my fingers but without the ability to verify them.

EDIT2: commands fprintd-enroll and fprintd-verify must be run 40 seconds apart from each other.. for some reason..

Same problem. I've tried to compile fprintd following PKGBUILD steps:

/usr/bin/ld: ./.libs/libfprintd.a(device.o):/tmp/fprintd/src/storage.h:47: multiple definition of `store'; main.o:/tmp/fprintd/src/storage.h:47: first defined here
collect2: error: ld returned 1 exit status

Any workaround?

I have the same problem:

make: *** [Makefile:448: check-recursive] Error 1 ==> ERROR: A failure occurred in build(). Aborting...

same problem here.

  CCLD     fprintd
/usr/bin/ld: ./.libs/libfprintd.a(device.o):(.bss+0x0): multiple definition of `store'; main.o:(.bss+0x0): first defined here
