Fails to build

[zippy2]

Maybe I'm doing something wrong, but all I did was:

clone the repo, cd repo/libfprint && ./autogen.sh && make

and I see a lot of compile errors, for instance:

drivers/vfs0090.c: In function ‘async_write’: drivers/vfs0090.c:82:46: error: ‘VFS_USB_TIMEOUT’ undeclared (first use in this function) async_write_callback, ssm, VFS_USB_TIMEOUT); ^ drivers/vfs0090.c:82:46: note: each undeclared identifier is reported only once for each function it appears in drivers/vfs0090.c: In function ‘async_read’: drivers/vfs0090.c:127:15: error: ‘EP3_IN’ undeclared (first use in this function) if (ep == EP3_IN) ^ drivers/vfs0090.c:130:28: error: ‘VFS_USB_TIMEOUT’ undeclared (first use in this function) VFS_USB_TIMEOUT); ^

And the list goes on and on. Also, any plans on merging this to libgprint later on? Thanks.

I'm not the developer of this driver, but I believe that the libfprint driver isn't ready for use(or even for compilation). If you want to test, try the prototype.

Oh, that one fails to initialize the device:

validity90.git/prototype # ./prototype | grep "Expected" Expected at char 012 Expected len: 84, but got 2 Expected len: 76, but got 16 Expected len: 4104, but got 2

validity90.git/prototype # ./prototype | tail -n5 0000 40 01 01 00 00 00 00 00 00 00 10 00 00 usb read: 0000 af 04 Expected len: 4104, but got 2 Invalid rsp6, can't get public key

What reader are you using? Looks like it might not be supported by this project

Bus 001 Device 003: ID 138a:0090 Validity Sensors, Inc.

Please correct me if I'm wrong, but since the driver is not ready yet I don't think you should be able to build that yet. If you go to validity90.git/prototype instead and make, does that work? Because I think that's all that is supposed to work so far. But I might be wrong.

[zippy2]

Well, as I say in the 3rd comment: libfprint provided with this repo fails to build; and the prototype does build but fails to initialize the device. Unsure why.

[lindhe]

Ah. Do you run the prototype as root (sudo ./prototype)?

[zippy2]

Yes. If you read the comment carefully you'll notice the sharp sign.

[lindhe]

I saw that, but everyone has a different prompt.

@zippy2 Have you used the device with windows? If not, try to install it in a VM(if you don't want to install it on hardware), setup your fingerprint and try prototype again
