前一篇文章已经介绍了如何下载tizen源码，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。

下面的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

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

然后更新源:

$sudo apt-get update

$sudo apt-get install gbs

$ 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

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。
