hello world動畫，Fuchsia之GN與Ninja構建hello world

接上篇：Fuchsia中GN與Ninja構建過程?

1.環境搭建
# cp  -rf out/ ~/home/GN //將編譯出來的out目錄的gn都拷貝出來
# emacs /etc/profile //添加環境配置
export PATH=$PATH:~/home/GN/out# cp -rf gn/examples/simple_build/build ~/home/GN/myApp
# cp  gn/examples/simple_build/.gn ~/home/GN/myApp
# mkdir -p ~/home/GN/myApp
# cd ~/home/GN/myApp2.demo
<1>.emacs hello.cpp
#include <iostream>
using namespace std;
int main(){cout << "Hello Fuchsia" <<endl;
} <2>.emacs BUILD.gn //編寫.gn構建配置文件
executable("hello") {sources = [ "hello.cpp" ]
}# gn gen out/default //Build.gn生成.ninja
# ninja -C out/default -v //編譯
# cd out/default
# ./hello
Hello Fuchsia!
