bitbake -S printdiff is a useful option as well.

You can also create snapshot before and after the change with
scripts/sstate-diff-machines.sh and compare the signatures manually.

bitbake-whatchanged is generally helpful here.  Do a build in one 
configuration, switch to the other, run
bitbake-whatchanged.  It will identify the hashes that have changed and try and 
chase them down.

That said perl is quite a deep recipe so rebuilding that will certainly bubble 
up the tree causing all sorts of rebuilds.


Thanks, I'll give this a try.



I've run this and I still don't have a clue.  Here's what I got.  Maybe
you can explain what I'm seeing?

e.g. why did the kernel need to be rebuilt if all I did was change perl?
what about mobile-broadband-info (which I think is pretty much just
static data)?

Thanks

bitbake-whatchanged is generally helpful here.  Do a build in one

bitbake-whatchanged.  It will identify the hashes that have changed and try and

That said perl is quite a deep recipe so rebuilding that will certainly bubble

Thanks, I'll give this a try.

[yocto] Strange build dependency

2016-03-14 Thread Gary Thomas 

I'm trying to sort out a problem with perl and have been switching
between two different versions.  What I don't understand is why
so many recipes are being rebuilt when I change.  I tried examining
the dependencies with -g -u depexp but I'm unable to see why it's
happening.

I'm building core-image-base (+perl) from a recent Poky checkout.
I notice that a number of packages that don't seem to be related
to perl (or even hardly to each other) are rebuilt, e.g. avahi,
openssl and others.

How can I find out what's going on here?

BTW, I'm using this [testing] layer for this effort (related to
my perl question from last week):
