[OE-core] OE-core] How do I find out why are packages being rebuilt?
I'm still having trouble with packages being needlessly rebuilt over and over. The worst of all it qt4-embedded, it takes about an hour to build. This is wasting a LOT of time. The classic OE never rebuilt a package until its version changed. How and why the current oe-core decides to rebuild package is a complete mystery to me, and the outdated documentation on the oe wiki isn't any help in that respect either. Can anyone explain how I can gain some insight into the trigger that causes a certain package to be rebuilt? ___ Openembedded-core mailing list Openembedded-core@lists.openembedded.org http://lists.linuxtogo.org/cgi-bin/mailman/listinfo/openembedded-core

The classic OE never rebuilt a package until its version changed. oe-core uses checksums of dependencies to determine what to rebuild - so if a class you inherit changes it's populate_packages_prepend() then the package task will re-execute, or if a dependeny package rebuilds then your package will rebuild too. If you're tracking oe-core master then this often means large rebuilds as there may have been changes to the base.bbclass or package.bbclass which obviously impacts everything, and the usual churn in the packages. bitbake-diffsigs will let you follow the signature differences that cause a rebuild up the tree to identify what has changed.

Change in oe-core I can live with. Things that puzzle me are that when I change the location of a bootloader data file in my local.conf, it suddenly decides to rebuild qt4-embedded. I also have two almost identical machines (same cpu, same kernel, just a few different plugs), and I cannot figure out why it builds two separate qt4 binaries. So I want to diagnose that. I have no idea where to start. ___ Openembedded-core mailing list Openembedded-core@lists.openembedded.org http://lists.linuxtogo.org/cgi-bin/mailman/listinfo/openembedded-core
