本文章中的源代码已提交到gitee仓库，地址：https://gitee.com/binary0010/depends/tree/master/c/brotli-1.1.0

1.brotli概述

brotli 是 Google 开发的高效无损压缩算法，基于 LZ77 和霍夫曼编码，通过字典优化与灵活压缩级别（0-11），在文本、代码等场景下实现比 gzip 高约 20% 的压缩率，同时保持快速解压速度。其流式处理特性适配现代网络协议，成为 Web 性能优化的核心技术之一。

brotli 广泛用于 Web 服务器（Nginx/Apache）与浏览器（Chrome/Firefox），通过 HTTP 压缩减少传输体积。移动端（如 Android）及文件存储领域（日志、配置）亦依赖其高压缩率降低资源消耗。开源代码支持多语言实现，BSD 许可推动跨平台集成，已成为 HTTPS 场景下提升数据传输效率的标准方案。

2.brotli编译

2.1.源代码下载

brotli源代码可以在github上下载，源代码下载地址：https://github.com/google/brotli/tags，找到最新版1.1.0版本，点击下图所示链接直接下载即可。

也可以自己复制这个地址下载：https://github.com/google/brotli/archive/refs/tags/v1.1.0.tar.gz

2.2.windows编译

先解压源代码到指定目录，brotli源代码中已经提供了CMakeList.txt脚本，后面我们按照规范会对该脚本进行修改。

2.2.1.源代码修改

由于brotil代码是c语言的，在vs2008中只支持c89标准语法，brotil代码中有一部分c99标准语法，为了支持vs2008我们对源代码进行修改。

2.2.2.修改CMake脚本

修改CMake脚本按照我们的设计的编译规范来进行构建和编译，修改源代码根目录下的CMakeLists.txt即可。

脚本涉及的内容主要是使用我们编译规范来对工程命名和输出，以及mt工程的链接库设置。

CMakeLists.txt完整内容：

# Available CMake versions:
# - Ubuntu  20.04 LTS   : 3.16.3
# - Solaris 11.4 SRU 15 : 3.15

# Since this project's version is loaded from other files, this policy
# will help suppress the warning generated by cmake.
# This policy is set because we can't provide "VERSION" in "project" command.
