为S3C6410,S5PC110等ARM平台快速构建一个Meego环境

Meego项目亦然停止，但是好的嵌入式Linux发行版舍Meego和Ubuntu以外，实难寻觅，所以我们很可能还存在Meego的移植需求，过程非常简单。依照http://wiki.meego.com/Image_Creation安装MIC2，准备如下的kickstarter文件（graphics使用软解码）

运行如下脚本可以得到Meego的image，之后解压缩，以loop方式mount并拷贝到SD卡的文件系统分区即可。

#!/bin/bashif [ `whoami` != root ]; then    echo "This script must be run as root, e.g.:"    echo "sudo $0"    exit -1fi# create meego image from kickstart. this will contain everything but the kernelmic-image-creator  --cache=../mycachedir --format=loop --arch=armv7hl --pkgmgr=yum --config=handset-armv7hl-prima2.ks --release=1.2.0.90.12.20110809.2

这一过程也可以自动化进行：

CURDIR=`pwd`OUTDIR=${CURDIR}/1.2.0.90.12.20110809.2/images/meego-handset-armv7hl-xxx/cd ${OUTDIR}bunzip2 meego-handset-armv7hl-xxx-1.2.0.90.12.20110809.2.img.bz2mkdir imgmount -o loop meego-handset-armv7hl-prima2-1.2.0.90.12.20110809.2.img imgif [ -d $1 ]; thenecho "copy meego rootfs to $1"cp -fa img/* $1umount imgrm -fr imgfi

启动Meego桌面的脚本如下：

#!/bin/bash# # we have no EGL for the moment, so we use SW render to# bootup desktop#export QT_GRAPHICSSYSTEM=nativeexport M_USE_SOFTWARE_RENDERING=1export DISPLAY=":0.0"xhost +/usr/bin/mthemedaemon &/usr/bin/meegotouchhome -fullscreen -show-cursor -software &
