[OE-core] 'elfutils' needed to build kernel (perf), but not listed in DEPENDS

[Koen Kooi]

Hi,

I finally tracked down the heisenbug that was causing kernel builds to fail: kernel*bbclass has no DEPENDS on elfutils, but it still tries to build perf.

While grepping I also stumbled accross this gem:

image-swab.bbclass:PARALLEL_MAKE_pn-elfutils = ""

Parallel make fails only when using swabber?

regards,

Koen
