Hi

I am currently experimenting with yocto and I was having a good start until now.

I want to rebuild a bootimage we have with yocto.
Currently the bootimage uses sfdisk 2.25.2 as later on the outputs changed and I didn't have time to adapt I always downgraded util-linux on the old bootimage.
To get quick results with a yocto based bootimage I wanted to do the same. I found a receive for a util-linux 2.25.2 package and added it to my recipes.

In my local.conf I added:



# downgrade util-linux
PREFERRED_VERSION_util-linux = "2.25.2"
 However this seems to work partially as the output of bitbake is now the following
 ERROR: Multiple versions of util-linux are due to be built (/home/user/opsi-linux-bootimage-yocto/poky/build/../meta-opsi-bootimage/recipes-opsi-bootimage/util-linux/util-linux_2.25.2.bb /home/user/opsi-linux-bootimage-yocto/poky/build/../meta/recipes-core/util-linux/util-linux_2.35.1.bb). Only one version of a given PN should be built in any given build. You likely need to set PREFERRED_VERSION_util-linux to select the correct version or don't depend on multiple versions.



How can I build a bootimage with a downgraded util-linux package?

Regards

Mathias

I'd suggest you move the old recipe out the way and that should quickly
give a clear idea on why its trying to build it.

I appreciate that isn't an ideal way to debug this but it is usually
effective...

Cheers,
