[转]如何编译tizen源码(图文教程)?

http://blog.csdn.net/flydream0/article/details/9004746

前一篇文章已经介绍了如何下载tizen源码(http://blog.csdn.net/flydream0/article/details/8996654)，下面我将继续讲述如何编译源码.

1 下载安装gbs编译工具

tizen源码是用gbs工具进行编译的，因此我们首先得将此工具下载下来，并且设置好。

下面以Ubuntu12.04版本为例.

1.1 添加gbs的源

用vim打开source.list文件:

$ sudo vim /etc/apt/sources.list

在最后添加两行:

deb http://download.tizen.org/tools/latest-release/Ubuntu_12.04/ /
deb-src http://download.tizen.org/tools/latest-release/Ubuntu_12.04/ /

如下图:

然后更新源:

$sudo apt-get update

安装gbs工具:

$sudo apt-get install gbs

可以相看当前gbs的版本:

$ gbs -V
gbs 0.16

1.2 修改.gbs.config文件

安装完gbs工具后，会在用户目录下生成一隐藏文件.gbs.config文件,用vim打开:

$vim .gbs.config

初始安装gbs后的.gbs.config文件的默认内容如下：

[general]
#Current profile name which should match a profile section name
profile = profile.tizen

[profile.tizen]
#Common authentication info for whole profile
#user =
#CAUTION: please use the key name "passwd" to reset plaintext password
#passwd =
obs = obs.tizen
#Comma separated list of repositories
repos = repo.tizen_latest
#repos = repo.tizen_main, repo.tizen_base

[obs.tizen]
#OBS API URL pointing to a remote OBS.
url = https://api.tizen.org
#Optional user and password, set if differ from profile's user and password
#user =
#passwd =

#Repo section example
[repo.tizen_latest]
#Build against repo's URL
url = http://download.tizen.org/releases/daily/trunk/ivi/latest/
#Optional user and password, set if differ from profile's user and password
#user =
#passwd =

#Individual repo is also supported
#[repo.tizen_base]
#url = http://download.tizen.org/releases/daily/trunk/ivi/latest/repos/base/ia32/packages/
#[repo.tizen_main]
#url = http://download.tizen.org/releases/daily/trunk/ivi/latest/repos/ivi/ia32/packages/

修改为:

[general]
#Current profile name which should match a profile section name
profile = profile.tizen

[profile.tizen]
#Common authentication info for whole profile
#user =
#CAUTION: please use the key name "passwd" to reset plaintext password
#passwd =
obs = obs.tizen
#Comma separated list of repositories
#repos = repo.tizen_latest
repos = repo.tizen_main, repo.tizen_base

[obs.tizen]
#OBS API URL pointing to a remote OBS.
url = https://api.tizen.org
#Optional user and password, set if differ from profile's user and password
#user =
#passwd =

#Repo section example
#[repo.tizen_latest]
#Build against repo's URL
#url = http://download.tizen.org/releases/daily/trunk/ivi/latest/
#Optional user and password, set if differ from profile's user and password
#user =
#passwd =

#Individual repo is also supported
[repo.tizen_base]
#url = http://download.tizen.org/releases/daily/trunk/ivi/latest/repos/base/ia32/packages/
url = http://download.tizen.org/releases/daily/2.0alpha/ivi-wayland/tizen-2.0alpha_20130522.2/repos/base/ia32/packages/
[repo.tizen_main]
#url = http://download.tizen.org/releases/daily/trunk/ivi/latest/repos/ivi/ia32/packages/
url = http://download.tizen.org/releases/daily/2.0alpha/ivi-wayland/tizen-2.0alpha_20130522.2/repos/ivi-wayland/ia32/packages/

2 本地编译源码

编译要求：

OS：Ubuntu12.04(64位)

内存:至少4G

Swap(交换分区大小):至少4G

注：内存和Swap大小都必要至少4G以上，不然会编译不过。操作系统必须是64位的，虽然在32位下也能源码编译通过，但是到后续制作镜像文件（使用mic工具时)会失败。

2.1 编译所有工程

输入如下指令进行编译:

cd到profile目录下, 然后通过如下指令对整个profile进行编译.

$ gbs build -A i586

接下来要花很长一段时间才能编译完。

编译完后如下界面:

2.2 编译单个工程

当然也可以只针对某个project进行编译，方法很简单，只需要cd到某个project的根目录，然后使用

$gbs build -A i586

即可。

2.3 编译后的输出目录

在默认情况下，gbs build后将用户的工作目录(即~/)下生成GBS-ROOT目录保存下载或编译后的结果。如下:

$ tree GBS-ROOT/ -L 3
GBS-ROOT/
└── local
    ├── BUILD-ROOTS
    │   └── scratch.i586.0
    ├── cache
    │   ├── f55c091634900cdc0c89559765a7b82f
    │   └── f92daa70cae15fb8d7f50595bc454ce0
    ├── order
    ├── repos
    │   └── tizen2.0alpha
    └── sources
        └── tizen2.0alpha

其中repos目录保存着RPM包:

$ tree repos/ -L 3
repos/
└── tizen2.0alpha
    └── i586
        ├── logs
        ├── repodata
        ├── RPMS
        └── SRPMS

其中RPMS和SRPMS保存着编译后的结果RPM包,这些包为下一步制作镜像文件提供RPM包。

3 远程编译源码

tizen 源码不但可以在本地进行编译，还可以使用远程编译。所谓远程编译就是将本地的修改自动上传到远程服务器OBS进行编译。对于tizen源码，使用gbs remotebuild指令来进行相关操作。这对于本地PC资源达不到要求的情况是十分有用的，只可惜远程编译需要授权才能进行，而目前我没有可以使用的 用户名和密码，因此，没有试验成功过。

有关如何制作镜像文件我将在后续文章中描述，敬请关注!
