[yocto] MULTILIB builds with Yocto: Status?

Sun Nov 24 01:53:03 PST 2013

*A follow up to this (after further testing with the Yocto image classes -
i.e. not my own custom image):*

*After adding the following to local.conf (keeping all other variables to
their defaults):*
require conf/multilib.conf
MULTILIBS = "multilib:lib32"
DEFAULTTUNE_virtclass-multilib-lib32 = "x86"

*Using the following Build configuration:*
BB_VERSION        = "1.21.0"
BUILD_SYS         = "i686-linux"
NATIVELSBSTRING   = "Ubuntu-12.04"
TARGET_SYS        = "x86_64-poky-linux"
MACHINE           = "nuc"
DISTRO            = "poky"
DISTRO_VERSION    = "1.5+snapshot-20131124"
TUNE_FEATURES     = "m64"
TARGET_FPU        = ""
meta
meta-yocto
meta-yocto-bsp    = "master:6a8307c35705bf6c9f49c368dd730deef3d2ae15"
meta-intel
meta-nuc          = "master:f5c2786e7ca190308523379706130e0c2be793c9"

*The MULTILIB build is successful with the following images:*
core-image-minimal
core-image-base
core-image-sato

As stated in the meta-nuc README, I then also added the following to
local.conf to enable hardware video acceleration:
LICENSE_FLAGS_WHITELIST += "commercial"

*Retrying the "core-image-sato" image build now results in errors:*

 *This appears to be a bug with the libx264 recipe.*

Any thoughts or comments on this?
Has anyone else tried MULTILIB builds with the NUC hardware (with hardware
acceleration enabled)?

Thanks,
Nick
