I managed to fix the issue. The problem was due to sudo as Alexander pointed out. For some reasons, sudo without password was not working correctly with that configuration provided in the docs.

I added this line

user ALL=(ALL) NOPASSWD:ALL

below the sudo group section in /etc/sudoers and then it started to work.

Thanks for your replies. I just checked the BBMULTICONF variable in local.conf and it is there.

Unfortunately If i now try to run  bitbake multiconfig:qemuarm-jessie:isar-image-base I stil get the same error.

Your error does look interesting. I would think that somehow your sudoers setting doesn't work correctly. Maybe try that out. It shouldn't ask for your password.

Otherwise I can suggest building isar inside a container such as:

    https://hub.docker.com/r/kasproject/kas-isar/

The system settings and basic dependencies are already setup there.
You just need to start it like this:

sudo docker run -v $(pwd):/mnt:rw -e USER_ID=$(id -u) --cap-add=SYS_ADMIN --cap-add=MKNOD --security-opt=seccomp:unconfined --privileged --device $(sudo /sbin/losetup -f) -rm -ti kasproject/kas-isar:latest bash

And it should work.

Cheers,
Claudius

Hello everyone,

I'm new to isar and today I made an attempt to build the default image
with it. I installed all the host tools necessary as it is written in
the docs. Then I followed strictly the doc/user_manual.

My host OS is debian jessie.

Unfortunately when I try to build an image I get this error:

/bitbake isar-image-base//

In that case, you are not using the multiconfig files Isar ships and
have to replicate all required settings into your local.conf. I would
rather recommend

bitbake multiconfig:qemuarm-jessie:isar-image-base

That will work (is also part of CI).

You also need to set the BBMULTICONF variable in local.conf.

Good point! I'm too much used to kas descriptions by now. ;)

Maybe just follow this:

https://github.com/ilbers/isar/blob/53ed253/doc/user_manual.md#building-target-images-for-multiple-configurations


And just use one configuration.

The documentation about 'One configuration' is not really up-to-date.

Cheers,
Claudius
