fuchsia编译

由于fuchsia代码主要在googlesource网站上，需要VPN才能方法。以下使用付费的express，开发环境为Ubuntu 16.04.3，如下：
 

$ cat /etc/issue
Ubuntu 16.04.3 LTS \n \l

首先安装并配置express：

$ sudo dpkg -i express_2.1.0-1_amd64.deb
$ express activate
Enter activation code:   //输入激活码

Activated.

$ express list

hk4     Hong Kong (HK)          Hong Kong - 4

$ express connect " Hong Kong"

Connecting to Hong Kong - 4...  100.0%                               
Connected to Hong Kong - 4

 

VPN连接好之后，以下命令下载fuchsia工程代码，curl的-s选项开启静默模式，减少打印信息：

$ curl -s "https://fuchsia.googlesource.com/fuchsia/+/master/scripts/bootstrap?format=TEXT" | base64 --decode | bash
~/work/fuchsia/.jiri_root/bin ~/work
cipd bootstrapped to path:"/home/kai/work/fuchsia/.jiri_root/bin/cipd"
~/work
Please add /home/kai/work/fuchsia/.jiri_root/bin to your PATH

Updating all projects
WARN: Some packages are skipped by cipd due to lack of access, you might want to run "cipd auth-login" and try again
ERROR: context deadline exceeded

期间遇到以上的错误，按照提示执行cipd auth-login命令，打开浏览器访问网址：https://www.googleapis.com/auth/userinfo.email，登录gmail账号，获取到激活码，如下配置：

$ fuchsia/buildtools/cipd auth-login

再次运行curl命令：

$ curl -s  "https://fuchsia.googlesource.com/fuchsia/+/master/scripts/bootstrap?format=TEXT" | base64 --decode | bash
~/work/fuchsia/.jiri_root/bin ~/work
cipd bootstrapped to path:"/home/kai/work/fuchsia/.jiri_root/bin/cipd"

Please add /home/kai/work/fuchsia/.jiri_root/bin to your PATH

Updating all projects
Done creating a Platform Source Tree at "/home/kai/work/fuchsia".
Recommended: export PATH="/home/kai/work/fuchsia/.jiri_root/bin:$PATH"

 

代码下载完成之后，按照提示配置PATH环境变量：

$ export PATH="/home/kai/work/fuchsia/.jiri_root/bin:$PATH"

 

如下所示，将cipd、fx和jiri三个程序添加到了执行路径PATH中。

$ ls fuchsia/.jiri_root/bin/ -l
total 27248
-rwxr-xr-x 1 kai kai 15317191 6月  10 10:43 cipd
lrwxrwxrwx 1 kai kai       16 6月  10 13:43 fx -> ../../scripts/fx
-rwxr-xr-x 1 kai kai 12579551 6月  10 13:39 jiri

 

设置编译目标，其中最后的参数格式为：PRODUCT.BOARD。可使用命令fx list-products和fx list-boards分别参考可用的product和board参数。

fuchsia$ fx set core.x64

fuchsia$ 

 

最后，运行fuchsia的编译命令：

fuchsia$ fx build
