   5 Target: Haswell CPU

   7 # Create your working directory
   8
   9 Create a working directory (for example "~/yocto"):
  10
  11         mkdir ~/yocto
  12         cd ~/yocto
  13
  14 Create a download directory (optional). It will act as a common download
  15 directory amongst projects:
  16
  17         mkdir ~/downloads
  18
  19 # Download sources
  20
  21 Downlaod Poky:
  22
  23         git clone git://git.yoctoproject.org/poky
  24
  25 Download Intel layers:
  26
  27         git clone git://git.yoctoproject.org/meta-intel
  28
  29 Download openembedded layers:
  30
  31         git clone git://git.openembedded.org/meta-openembedded
  32
  33 Download tizen layer:
  34
  35         git@github.com:eurogiciel-oss/meta-tizen.git

  37 # Configuration
  38
  39 Configure the environment:
  40
  41         cd poky
  42         . ./oe-init-build-env
  43
  44 # Configuration files
  45
  46 ## conf/bblayer.conf
  47
  48 This file contains the list of the layers in which poky has to search
  49 for the recipes.
  50
  51         # LAYER_CONF_VERSION is increased each time build/conf/bblayers.conf
  52         # changes incompatibly
  53         LCONF_VERSION = "6"
  54
  55         BBPATH = "${TOPDIR}"
  56         BBFILES ?= ""
  57

  73
  74 Most of default values can be kept. The one that needs to be changed is:
  75
  76         MACHINE ?= "haswell-wc"
  77
  78 Other useful option to set:
  79
  80 * Donwload directory:
  81
  82         DL_DIR ?= "${HOME}/yocto/downloads"
  83
  84 Setting the download directory DL_DIR to a directory shared amongst
  85 projects prevents common data from being downloaded for each project.
  86
  87 * Terminal emulator:
  88
  89         OE_TERMINAL = "screen"
  90
  91 The terminal emulator you want to use.
  92
  93 Example of a complete configuration file (without comments):
  94
  95         BB_NUMBER_THREADS ?= "${@oe.utils.cpu_count()}"
  96         PARALLEL_MAKE ?= "-j ${@oe.utils.cpu_count()}"
  97         MACHINE ?= "genericx86-64"
  98         DL_DIR ?= "${HOME}/yocto/downloads"
  99         BB_GENERATE_MIRROR_TARBALLS = "1"
 100         DISTRO ?= "poky"
 101         PACKAGE_CLASSES ?= "package_rpm"
 102         EXTRA_IMAGE_FEATURES = "debug-tweaks"
 103         USER_CLASSES ?= "buildstats image-mklibs image-prelink"
 104         OE_TERMINAL = "screen"
 105         PATCHRESOLVE = "noop"
 106         BB_DISKMON_DIRS = "\

 111                 ABORT,${DL_DIR},100M,1K \
 112                 ABORT,${SSTATE_DIR},100M,1K"
 113                 PACKAGECONFIG_pn-qemu-native = "sdl"
 114                 ASSUME_PROVIDED += "libsdl-native"
 115         CONF_VERSION = "1"
 116
 117 # Build the Tizen Common image
 118
 119         bitbake tizen-common-core-image-minimal
 120
 121 Two useful options are:
 122
 123 'k' "Continue as much as possible after an error. While the target that
 124     failed and anything depending on it cannot be built, as much as
 125     possible will be built before stopping."
 126
 127 'v' "Output more log message data to the terminal."
 128
 129 Which gives:
 130
 131         bitbake -kv tizen-common-core-image-minimal
 132
 133 The generate image can be found in tmp/deploy/images/genericx86-64/
