Hi all
I am trying to compile poky-dizzy-12.0.1(MACHINE ?= "beaglebone") using meta-toolchain.
 
so i downloaded dizzy from
  http://downloads.yoctoproject.org/releases/yocto/yocto-1.7.1/poky-dizzy-12.0.1.tar.bz2
meta-linaro  from
https://git.linaro.org/openembedded/meta-linaro.git
 I have changed bblayers.conf as below
 
 
 # LAYER_CONF_VERSION is increased each time build/conf/bblayers.conf
# changes incompatibly
LCONF_VERSION = "6"
BBPATH = "${TOPDIR}"
BBFILES ?= ""
BBLAYERS ?= " \
  /home/praveenk/work/poky-dizzy-12.0.1/meta \
  /home/praveenk/work/poky-dizzy-12.0.1/meta-yocto \
  /home/praveenk/work/poky-dizzy-12.0.1/meta-yocto-bsp \
   /home/praveenk/work/poky-dizzy-12.0.1/meta-linaro/meta-linaro-toolchain \
  "
BBLAYERS_NON_REMOVABLE ?= " \
  /home/praveenk/work/poky-dizzy-12.0.1/meta \
  /home/praveenk/work/poky-dizzy-12.0.1/meta-yocto \
I added required changes in local.conf
 
 
MACHINE ?= "beaglebone"
DEFAULTTUNE = "cortexa8hf-neon"

PREFERRED_PROVIDER_glibc                                        ?= "glibc"

PREFERRED_VERSION_gcc                                           ?= "linaro-4.9%"
PREFERRED_VERSION_gcc-cross                                     ?= "linaro-4.9%"
PREFERRED_VERSION_gcc-cross-initial                             ?= "linaro-4.9%"
PREFERRED_VERSION_gcc-cross-intermediate                        ?= "linaro-4.9%"
PREFERRED_VERSION_gcc-cross-canadian                            ?= "linaro-4.9%"
PREFERRED_VERSION_gcc-crosssdk                                  ?= "linaro-4.9%"
PREFERRED_VERSION_gcc-crosssdk-initial                          ?= "linaro-4.9%"
PREFERRED_VERSION_gcc-crosssdk-intermediate                     ?= "linaro-4.9%"
PREFERRED_VERSION_gcc-runtime                                   ?= "linaro-4.9%"
PREFERRED_VERSION_nativesdk-gcc-runtime                         ?= "linaro-4.9%"
PREFERRED_VERSION_libgcc                                        ?= "linaro-4.9%"
PREFERRED_VERSION_nativesdk-libgcc                              ?= "linaro-4.9%"
PREFERRED_VERSION_gcc-cross-canadian-${TRANSLATED_TARGET_ARCH}  ?= "linaro-4.9%"
 
but still it is building gcc-4.9 instead of gcc-linaro-4.9
 
 
Thanks
Praveen
