Description Ross Burton 2015-01-14 12:08:02 UTC 
With the new pynotify code breaking on old kernels, we see that bitbake is searching for classes in very unusual places:

/home/ross/Yocto/poky/meta/recipes-kernel/sysprof/classes/pkgconfig.bbclass
/home/ross/Yocto/poky/build/classes/kernel-arch.bbclass
/home/ross/Yocto/poky/meta/classes/classes/siteconfig.bbclass
Comment 1 Richard Purdie 2015-01-15 14:55:29 UTC 
It turns out there is a reason for this. If for example A.bbclass (in meta/clases) does "inherit B", the system will look for B in "." and "./classes" where "." is the directory containing A.bbclass so you can end up with some bizzare looking path constructs. I'm not sure we can actually do much about this.
Comment 2 Richard Purdie 2015-01-21 14:08:13 UTC 
As previously described, whilst it looks odd, there is a good reason for this.
