之前已讲解了如何下载及编译tizen源码,接下来我将讲解如下将制作镜像文件。

1 安装mic工具

tizen是使用MIC工具来制作其镜像文件的，因此我们首先得安装它。

$ sudo apt-get install mic

查看MIC工具的当前版本：

$ mic --version
mic 0.19.1 (Ubuntu 12.04 precise)

2 下载ks文件

wget http://download.tizen.org/releases/daily/2.0alpha/ivi-wayland/tizen-2.0alpha_20130522.2/images/ivi-wayland-release/ivi-wayland-release.ks

下载完后会在当前目录下有一个名为ivi-wayland-release.ks的文件，打开此文件，如下内容:

此文件为mic的配置文件，描述mic如何制作镜像文件。有关此文件的说明请参考： http://blog.csdn.net/flydream0/article/details/9162187 一文的第5章。

默认情况下repo使用的是远程资料库的RPM包。

3 使用MIC工具从远程repo下载RPM包并制作镜像文件

使用如下指令生成镜像文件:

$ sudo mic create raw ivi-wayland-release.ks --pack-to=test.tar.bz2 --logfile=log

其中 create表示创建镜像文件，raw表示raw格式的镜像, ivi-way...这里指定ks文件. --pack-to=xxx 表示打包生成test.tar.bz2文件，即此raw镜像文件打包到test.tar.bz2, --logfile=xxx表示将打印信息存放到log文件中.

如下图:

最终结束后，会在当前目录生成log文件，保存制作镜像文件过程中的打印信息，同时会生成mic-output目录，压缩打包后的镜像文件test.tar.bz2文件就放在此目录下。

$ tree mic-output/ -L 3
mic-output/
├── ivi-wayland-release-201306251509.xml
└── test.tar.bz2

0 directories, 2 files

注：默认情况下，mic工具会在/var/tmp目录下创建一mic目录，然后在mic目录下创建cache目录用来保存从远程repo下载的RPM包:

$ tree mic -L 2
mic
├── build
├── cache
│   ├── etc
│   ├── packages
│   ├── raw
│   ├── solv
│   ├── Tizen-base
│   ├── Tizen-ivi-wayland
│   └── var
└── device
    └── loop0

4 使用本地RPM包生成镜像文件

使用如下指令:

$ sudo mic create raw ivi-wayland-release.ks --pack-to=local_test.tar.bz2 --logfile=log1 --local-pkgs-path=/home/arthur/GBS-ROOT/local/repos

其中--local-pkgs-path=后面为使用gbs build时生成的本地repo的所在目录。见: http://blog.csdn.net/flydream0/article/details/9004746 一文的2.3节。

注：如果gbs build生成的目录下，即repos的tizenxxx目录下包含多个硬件平台架构的目录时，可以在MIC指令后通过-A选项来指令目标平台的架构，如：

$ sudo mic create raw ivi-wayland-release.ks --pack-to=local_test.tar.bz2 --logfile=log1 --local-pkgs-path=/home/arthur/GBS-ROOT/local/repos -A i586
