Installation using distribution packages
The Download page contains links to distribution packages.
Installation from sources
At first, check if libfprint and pam_fprint packages available for your distro.
Follow this way only if there's no packages for your distro!
You'll need gcc and some development packages installed.
Get libfprint sources.
Unpack libfprint-version.tar.bz2 somewhere:
tar -xjf libfprint-0.0.4.tar.bz2
cd libfprint-0.0.4 ./configure --prefix=/usr make sudo make install
Last one command requires root privileges.
Use same technique for pam_fprint and fprint_demo.
Note that libfprint is young project, and its API isn't stable so you can broke pamfprint and fprint_demo when updating to new versions. Reinstall pam_fprint and fprint_demo immediatelly after libfprint update._
Q: During pam_fprint configure I've got something like:
checking for FPRINT... configure: error: Package requirements ("libfprint") were not met
A: Probably, you've installed libfprint in /usr/local. Remove all libfprint's files from /usr/local and follow instruction in 2nd paragraph
Q: I've installed libfprint into /usr, but pam_fprint's configure still complains about missing libfprint!
A: Try to invoke following command before running configure:
Q: Running pam_fprint_enroll and fprint_demo from user fails with message like following:
aes1610:error [dev_init] could not claim interface 0
A: You have no permissions to access /proc/bus/usb (/dev/bus/usb). Solution depends on distro. On Gentoo you should add your user to usb group. Same solution should be applicable for other distros. Invoke mount | grep usb, it should produce something like:
anarsoul@anarsoul-laptop ~ $ mount | grep usb usbfs on /proc/bus/usb type usbfs (rw,noexec,nosuid,devmode=0664,devgid=85)
So, /proc/bus/usb belongs to group with gid 85. Now let's get group name:
anarsoul@anarsoul-laptop ~ $ cat /etc/group | grep 85 | cut -f 1 -d: usb
Add your user to this group:
sudo usermod -a -G usb your_user_name
