[fprint] libfprint on maemo (OS2008)

[Rafael Brandão]

Greetings.

I'm trying to install libfprint on a tablet (nokia n810) with OS2008 and
I've been in a bit of trouble. When I've finally could get through the 'make
install' step and tried to run libfprint example code "enroll", I've got
this:

This program will enroll your right index finger, unconditionally
overwriting any right-index print that was enrolled previously. If you want
to continue, press enter, otherwise hit Ctrl+C

Could not open device.


It have detected my fingerprint device, and that's very nice, but I don't
understand these "ioctl" errors. I was wondering if there's anyone who could
provide me more answers. I'm discussing this issue also here:

Any feedback will be greatly appreciated.
