Agreed, that's bad, I was testing it in setup where we publish the sstate archive from the builder with the same architecture and have similar setup building just -native recipes on 32bit for 32bit devs. So this problem should have hit us as well, I'll recheck. > Cheers, > > Richard > > > diff --git a/meta/lib/oe/sstatesig.py b/meta/lib/oe/sstatesig.py > > index 3011f16..8b0e344 100644 > > --- a/meta/lib/oe/sstatesig.py > > +++ b/meta/lib/oe/sstatesig.py > > @@ -36,10 +36,6 @@ def sstate_rundepfilter(siggen, fn, recipename, task, > > dep, depname, dataCache): > > if isPackageGroup(fn): > > return False > > > > - # Drop native/cross/nativesdk dependencies from target recipes > > - if isNative(depname) or isCross(depname) or isNativeSDK(depname): > > - return False > > - > > # Exclude well defined machine specific configurations which don't > > change ABI > > if depname in siggen.abisaferecipes and not isImage(fn): > > return False > > -- Martin 'JaMa' Jansa jabber: [email protected]
