Ninja安装流程见一个能直接运行的Ninja例子build.ninja文件怎么写Gn安装流程见Ubuntu18.04下安装Gn软件 这是一个简单的BUILD.gn配置文件
jimubuntu:~/0_Git/third_party_gn/examples/simple_build$ cat BUILD.gn

}shared_library(hello_shared) {sources [hello_shared.cc,hello_shared.h,]defines [ HELLO_SHARED_IMPLEMENTATION ]
}static_library(hello_static) {sources [hello_static.cc,hello_static.h,]
}这是Gn官方的例子在Gn的源码里面 使用Ubuntu系统安装Git、Ninja、Gn、Clang软件git clone gitgitee.com:openharmony/third_party_gn.git 拉取源码或者https://gitee.com/openharmony/third_party_gn/repository/archive/master.zip 下载源码 cd examples/simple_build/ 下载源码后进入其中的子目录 ls 先看看里面的文件
jimubuntu:~/0_Git/third_party_gn/examples/simple_build$ ls

}gn gen -C out 按Gn规则文件生成Ninja配置文件
jimubuntu:~/0_Git/third_party_gn/examples/simple_build$ gn gen -C out
Done. Made 3 targets from 4 files in 45mscd out/ 进入输出目录看看生成的什么内容
