Scratchbox2安装配置

主要参考文档：

--------------------------------------------------------------------------------------------------------------------------

sudo apt-get install mercurial bison flex texinfo libtool build-essential libncurses-dev

安装zlib

apt-get install zlib1g-dev

apt-get install libglib2.0-dev

apt-get install realpath

mkdir –p ~/sbox2/src/

cd ~/sbox2/src/

下载：

git被防火墙屏蔽，用https下载，主页http://maemo.gitorious.org/scratchbox2

git clone https://git.gitorious.org/scratchbox2/scratchbox2.git

编译Scratchbox2:

cd scratchbox2

./autogen.sh

make install prefix=$HOME/sb2

下载qemu：http://wiki.qemu.org/Download

mkdir –p ~/qemu/src/

~/qemu# git clone https://github.com/qemu/QEMU.git

cd QEMU

./configure --prefix=$HOME/sb2 --target-list=arm-linux-user

make && make install

mkdir $HOME/buildroot
cd $HOME/buildroot

cp -a ../cross/arm-mv5sft-linux-gnueabi/sys-root/{lib,etc,usr} .

sb2-init marvell arm-mv5sft-linux-gnueabi-gcc

发现ldconfig 失败，所以拷贝sbin目录过来（里面有ldconfig）

cp -a ../cross/arm-mv5sft-linux-gnueabi/sys-root/sbin .

sb2-init marvell arm-mv5sft-linux-gnueabi-gcc

……

sb2-init completed successfully, have fun!

sb2登陆内部使用：
root@james-desktop:~/buildroot# sb2

gcc hello.c –o hello

sb2外面使用：

$ sb2 gcc -o hello hello.c
$ sb2 ./hello
Hello, World!

sb2 ./configure

sb2 make

sb2 -eR make install

sb2 -R -m emulate make install

~/sbox2/src/scratchbox2/docs# man ./sb2.1

MAPPING MODES

There are three development-oriented modes, that are intended for cross-compilation:

3个开发模式，用来交叉编译

"simple"  makes  only  the  very  basic  modifications  to  the  file  environment:  For  example, /usr/include refers to
/usr/include in the target root file system, not to the real /usr/include of the host (and  the  same  applies  to  /lib,
/usr/lib, and many other directories).  Typical toolchain commands, i.e. commands that are used to create binary programs
(like gcc, as and ld) refer to tools that were supplied with the the cross-compiler which was  configured  with  sb2-init
(also when used with full pathname: /usr/bin/gcc, /usr/bin/as, etc)

simple根文件用的是target root，工具链用的是配置的工具链（如arm的），其他的工具来自主机。

The  "simple" mode usually takes other tools directly from the host OS.  This approach means that simple tools work fine,
and well-behaving OSS projects can be compiled with the "simple" mode. The drawback is that there are some  cases,  where
such a simple approach fails.

apt-get install debootstrap

debootstrap --verbose --arch armel --foreign lenny  rootfs/armel/ http://ftp.at.debian.org/debian

这个不知道怎么用？？

发现mount上去这个根文件可以用。

构建ubuntu根文件：

http://www.plugcomputer.org/plugwiki/index.php/Ubuntu_9.0.4_Plug_Computer_Distribution

https://wiki.ubuntu.com/ARM/RootfsFromScratch

apt-get install rootstock

rootstock -f ubuntu -l james -p 123 -d lucid --serial ttyS0

rootstock --seed option problem：可以添加安装包https://answers.launchpad.net/project-rootstock/+question/153564

root@james-desktop:~# du -hs *
77M armel-rootfs-201112131534.tgz

但是通过nfs运行ubuntu根文件时候发现segment fault，运行不了。
