Examples to build C++ code
This folder is part of the C++ Bazel Tutorial, found at https://bazel.build/start/cpp
This package will showcase how to build C++ code in stages.
此文件夹是 C++ Bazel 教程的一部分，位于 https://bazel.build/start/cpp
此包将展示如何分阶段构建 C++ 代码。
Stage 0
The zeroth stage shows how to setup the toolchain so that Bazel doesn’t use the system’s C++ gcc toolchain.
This provides hermeticity, making the build more portable and reproducible on other computers.
Note, this is for Linux only. MacOS and Windows still use the system gcc.
第零阶段展示了如何设置工具链，以便 Bazel 不使用系统的 C++ gcc 工具链。
这提供了密封性，使构建在其他计算机上更具可移植性和可重复性。
注意，这仅适用于 Linux。MacOS 和 Windows 仍然使用系统 gcc。
Stage 1
The first stage is really simple and shows you how to compile a binary with a single source file.
第一阶段非常简单，向您展示如何使用单个源文件编译二进制文件。
Stage 2
The second stage will showcase how to build an application with multiple source and header files, separated in a library and a binary.
第二阶段将展示如何构建具有多个源文件和头文件的应用程序（分为库和二进制文件）。
Stage 3
The third stage showcases how to link multiple build directories by building multiple libraries in different packages and then connecting it up with the main application.
第三阶段展示了如何通过在不同的包中构建多个库来链接多个构建目录，然后将其与主应用程序连接起来。
