[yocto] Dependency change : work-shared: do_preconfigure ?!?! [morty]

[Jan-Simon Möller]

Hi !

I have a morty-based project here which I already built once and I'm now about to rebuild it without any modifications on the same machine.

I checked with bitbake-whatchanged before starting any build and every time I see this:
=== Dependencies changed: (1 tasks)
  work-shared: do_preconfigure

=== Summary: (6626 changed, 4 unchanged)
Newly added: 6625
PV changed: 0
PR changed: 0
Dependencies changed: 1




I'd actually expect way less to be 'changed' as to what bitbake-whatchanged tells me.



---------------------

bitbake-whatchanged -v  shows this

=== The verbose changes of work-shared.do_preconfigure:
runtaskdeps changed from 
['autoconfautoconf_2.69.bb.do_populate_sysroot:virtual:native', 'gccgcc-source_6.2.bb.do_patch', 'gnu-configgnu-config_git.bb.do_populate_sysroot:virtual:native'] to ['autoconfautoconf_2.69.bb.do_populate_sysroot:virtual:native', 'gccgcc-source_6.2.bb.do_patch', 'gnu-configgnu-config_git.bb.do_populate_sysroot:virtual:native']

Hash for dependent task gnu-configgnu-config_git.bb.do_populate_sysroot:virtual:native changed from 9beadb38a5586266137d12754a7da0e2 to 2b201b2787194e74f97f25d9908dfd61

What puzzles me is the double PN in the task names ... e.g.
'autoconfautoconf' . And of course the change of the hash.

gnu-config hash 9beadb is there but there is no 2b201b27,


Hints ?
