From 39bfa0dd3237cbca47e7fca1075d521f9d073f25 Mon Sep 17 00:00:00 2001 From: Patrick Ohly Date: Tue, 11 Apr 2017 20:38:38 +0200 Subject: recipes/*-cross recipes: ignore TARGET_ARCH sstate hash "yocto-compat-layer.py --machines" showed that shared packages like gcc-cross-powerpc64 have a sstate signature that depends on TUNEFLAGS. As a result, there are unnecessary rebuilds and potential conflicts in a multiconfig. That's due to the way how TARGET_ARCH is set. Richard Purdie suggested setting TARGET_ARCH[vardepvalue] as fix, which works. It would be shorter to do that in cross.bbclass instead of repeating the relevant line in different recipes, but Richard was concerned about potential side-effects in other usages of cross.bbclass. TARGET_GOARM as used in go.inc is still causing signature differences for go-cross-powerpc64 and machines b4420qds-64b and p5020ds-64b. This needs further investigation.
