Best practice to resolve dependency loops ?

Best practice to resolve dependency loops ?

[Hauser, Wolfgang (external)]

Hello,

the current org.openembedded.dev fails while building a image based on
console-base-image complaining about unresolved dependency loops.
The debugging output of bitbake list the failing packages, but not the
dependencies causing the problem.

What is the best practice to examine and solve such problems ?

regards
Wolfgang Hauser

I would like to add an additional question:

bitbake supports -g for dependency trees in dot syntax. What is the best tool to browse these files. I checked graphviz but this just paints complete unviewable posters. Is there e.g something like 
a dot to html converter aavialable?

I've read about parsing the .dot file using grep or awk. I have to
search it again.

I found it easiest to run contrib/dependsgraph/dependsgraph.sh and
read the reduced.dot file directly in a text editor.

You can use the dependency explorer UI built into Bitbake:

bitbake -g -u depexp some-task
