Zircon构建和运行
1、下载源码
git clone https://github.com/fuchsia-mirror/zircon
２、安装工具链
如果你的开发环境是Linux，已有预编译的工具链可直接进行下载，只需在Zircon的工作目录下运行下列脚本即可：
./scripts/download-prebuilt
3、构建Zircon
对于aarch64
make -j4 arm64对于x64
make -j4 x64构建生成的文件位于zircon/build-{arm64,x64}下
4、运行
# for aarch64
./scripts/run-zircon-arm64# for x86
./scripts/run-zircon-x64这里以arm64为例子
pomelo@pomelo-mj:~/work/zircon/zircon$ ./scripts/run-zircon-arm64
