환경변수 및 라즈베리 파이 빌드할 경로 생성

pi@raspberrypi ~/src/yoctoProject $ source oe-init-build-env raspberryPiBuild/ You had no conf/local.conf file. This configuration file has therefore been created for you with some default values. You may wish to edit it to use a different MACHINE (target hardware) or enable parallel build options to take advantage of multiple cores for example. See the file for more information as common configuration options are commented. You had no conf/bblayers.conf file. The configuration file has been created for you with some default values. To add additional metadata layers into your configuration please add entries to this file. The Yocto Project has extensive documentation about OE including a reference manual which can be found at:     http://yoctoproject.org/documentation For more information about OpenEmbedded see their website:     http://www.openembedded.org/ ### Shell environment set up for builds. ### You can now run 'bitbake <target>' Common targets are:     core-image-minimal     core-image-sato     meta-toolchain     adt-installer     meta-ide-support You can also run generated qemu images with a command like 'runqemu qemux86'

라즈베리 파이 빌드를 위한 환경 설정 1

pi@raspberrypi ~/src/yoctoProject/raspberryPiBuild $ vim conf/local.conf MACHINE ?= "raspberrypi"

라즈베리 파이 빌드를 위한 환경 설정 2

pi@raspberrypi ~/src/yoctoProject/raspberryPiBuild $ vim conf/bblayers.conf # LAYER_CONF_VERSION is increased each time build/conf/bblayers.conf # changes incompatibly LCONF_VERSION = "6" BBPATH = "${TOPDIR}" BBFILES ?= "" BBLAYERS ?= " \   /home/pi/src/yoctoProject/meta \   /home/pi/src/yoctoProject/meta-yocto \   /home/pi/src/yoctoProject/meta-yocto-bsp \   /home/pi/src/yoctoProject/meta-raspberrypi \   " BBLAYERS_NON_REMOVABLE ?= " \   /home/pi/src/yoctoProject/meta \   /home/pi/src/yoctoProject/meta-yocto \   "

빌드를 위한 패키지 설치(라즈비안에서 한 120메가 다운로드 / 500메가 용량 필요)

pi@raspberrypi ~/src/yoctoProject/raspberryPiBuild $ sudo apt-get install sed wget cvs subversion git-core coreutils unzip texi2html texinfo libsdl1.2-dev docbook-utils gawk python-pysqlite2 diffstat help2man make gcc build-essential g++ desktop-file-utils chrpath libgl1-mesa-dev libglu1-mesa-dev mercurial autoconf automake groff libtool xterm

빌드 시작

pi@raspberrypi ~/src/yoctoProject/raspberryPiBuild $ bitbake core-sato-image

리부팅후 환경변수 재설정

pi@raspberrypi ~/src/yoctoProject $ source oe-init-build-env

끄응.. 왜 안되지? 라즈베리에서 라즈베리를 빌드하려고 해서 그런가? ㅋㅋㅋ

pi@raspberrypi ~/src/yoctoProject/raspberryPiBuild $ bitbake core-sato-image
