Dear All,
I have three intree recipes A, B and C which are part of the same layer.

There is no dependency between B and C. Only important thing is that B
and C are not build simultaneously. This is not a problem unless I use
configure BB_NUMBER_THREADS> 1. Than builds B and C starts to collide
and produce mess because they are both intree builds.
What are you doing that makes these clash?
usually it crashes during "ln -sf target dest" which is executed
simultaneously with same parameters for both builds. There are other
issues as well in addition to this ln issue.
Is there something like a mutex/lock mechanism in openembedded-core,
which would forbid two recipes to be build simultaneously?
Just make C depend on B
I have already considered this, but unfortunately I also have
configurations where only B is included or where only C is included :(
Thanks,
Radek

Fixing the packages, is probably the way to go.
You could also create pseudo package "D" which is available in several
versions.
Package D-1.0c: Package D is depending on nothing
Package D-1.0bc: Package D is depending on B
Package C is always dependent on Package D and A.
Package B is always dependent on Package A
If you set PREFERRED_VERSION_D = "1.0c"
C is depending on D, which is depending on nothing, and C is depending on A.
No problem, A and C is built.
If you set PREFERRED_VERSION_D = "1.0c"
C is depending on D, which is depending on B. B and C is depending on A.
A is built, then B is built, and then D finalizing with C.
If you only want B, don't include C in the image.
Not tested, but it looks like it would work.
