It is generally impossible to directly compare two git hashes and decide whether one is "greater" than the other. This is why most git recipes have PV = "0.0+git${SRCPV}" so that you can change 0.0 when something major changes. That way you can put a constraint in the second recipe. This is a fundamental problem with git versioning and not something we can fix generically.

In theory, yes and in practise, bitbake does actually do this. Unfortunately autotools sometimes do not rebuild things when it should. This is why I've been promoting the B != S patch set which forces things to rebuild in scenarios like this and removes the issue from autotools and lets us handle it ourselves. So my recommendation would be to opt in to that include file and this should help errors like this. The change I'd love to commit is: http://git.yoctoproject.org/cgit.cgi/poky-contrib/commit/?h=rpurdie/t2&id=aedf7d207190f18466e82cbc9b3d49b19b3f376f but I think its now too late to do this by default in 1.6.

At this point you'll probably have to look at the shlibs code in package.bbclass and see why its not picking up the shlib dependencies correctly for the packages... It does appear there is some problem there but its hard to saw what without a test case to reproduce.

I could isolate the problem. :) If a package contains a shared library *and* a binary (e.g. a related command line tool) then the soname major version *is not appended* to the package name (see debian_package_name_hook in debian.bbclass). All other problems are aftereffects. Is this an intended behaviour? There should be a big fat warning if this is the case. Or is it a bug? -- DResearch Fahrzeugelektronik GmbH Otto-Schmirgal-Str. 3, 10319 Berlin, Germany Tel: +49 30 515932-237 mailto:sl...@dresearch-fe.de Fax: +49 30 515932-299 Geschäftsführer: Dr. Michael Weber, Werner Mögle; Amtsgericht Berlin Charlottenburg; HRB 130120 B; Ust.-IDNr.

No it is used by the binary which is part of the package *and* some other binaries. So i've to split the package into two packages of which one contains only the shared object.
