AttributeError: 'SignatureGenerator' object has no attribute 'file_checksum_values'

AttributeError: 'SignatureGenerator' object has no attribute 'file_checksum_values'

[Amit Chaudhuri]

Hi all,

I am following the "Hello World" example from
yoctoproject.org/docs/1.6/bitbake-user-manual/bitbake-user-manual.html#the-hello-world-example.

I have sourced the oe-init-build-env script.

I get an error message when trying to execute the bitbake printhello
command from my project dir.  Command and output here:

NOTE: Tasks Summary: Attempted 0 tasks of which 0 didn't need to be
rerun and all succeeded.

Summary: There were 2 ERROR messages shown, returning a non-zero exit code.

Bitbake version is:

BitBake Build Tool Core version 1.20.0, bitbake version 1.20.0

OS details:

cat /etc/os-release
NAME=openSUSE
VERSION="13.1 (Bottle)"
VERSION_ID="13.1"
PRETTY_NAME="openSUSE 13.1 (Bottle) (x86_64)"
ID=opensuse
ANSI_COLOR="0;32"
CPE_NAME="cpe:/o:opensuse:opensuse:13.1"
BUG_REPORT_URL="https://bugs.opensuse.org"
HOME_URL="https://opensuse.org/"
ID_LIKE="suse"

The only difference I can see between example and my attempt is the
layer name (testlayer vs mylayer) and I've checked that I am being
consistent.

The error message suggests to me that there's a versioning problem on
the SignatureGenerator.

Can anyone point me in the right direction here?
Happy to provide additional info (e.g. strace).

Regards,
Amit

Hello,

What's version of bitbake are you using, please ?

$ bitbake --version

Have you set BB_SIGNATURE_HANDLER ? You can try to add:

BB_SIGNATURE_HANDLER = 'OEBasicHash'

to con/local.conf.

I think that this has been fixed even if you don't set the
BB_SIGNATURE_HANDLER which means 'noop' in the latest bitbake.
