OpenEmbedded uses the bitbake tool which is developed in python to generate images from packages built from recipes provided in layers
Poky是基于Bitbake和oe(OpenEmbedded)的参考,提供了一些有用的脚本.
你自己的项目可以参考Poky,直接使用后两者,也可以基于Poky,使用其提供的一些脚本
一、环境搭建
sudo apt-get install gawk wget git-core diffstat unzip texinfo gcc-multilib \
build-essential chrpath socat libsdl1.2-dev xterm
git clone git://git.yoctoproject.org/poky
cd poky
git checkout -b krogoth origin/krogoth
source oe-init-build-env二、常用配置
local.conf
#删除每个软件包的构建结构以节省空间
INHERIT += "rm_work"
#指定要编译的架构
MACHINE = "qemux86"
或通过echo方式，
echo 'MACHINE = "qemux86"' >> conf/local.conf
#指定中间生成的软件包格式
PACKAGE_CLASSES ?= "package_rpm"
汇总
MACHINE = "qemux86"
SHAREDIR = "/media/itviewer/linux"
DL_DIR = "${SHAREDIR}/downloads"
DISTRO = "poky"
PACKAGE_CLASSES = "package_rpm"
INHERIT+="rm_work"
RM_OLD_IMAGE = "1"bblayers.conf
#添加layer
bitbake-layers add-layer "$HOME/poky/meta-intel"
三、编译或运行
查看target
ls meta*/recipes*/images/*.bb
#编译镜像或软件包
bitbake core-image-base
runqemu qemux86
四. 查看依赖
bitbake -u depexp -g weston
