0x00 前言
觊觎drogon WEB高性能表现已久，虽然开发部分相对简单，但考虑到部署环境均为Linux，且版本情况分布不一，于是就花费两天整理明白了：纯静态编译输出执行文件的流程。
官网：https://github.com/drogonframework/drogon
0x01 虚拟机安装
- 基础工具安装
sudo apt update
sudo apt install vim net-tools -y
- 开启远程 ssh
sudo apt install openssh-server
sudo vim /etc/ssh/sshd_config
# 去掉注释：
ListenAddress 0.0.0.0
# 重启服务
sudo service ssh status
sudo service ssh restart
- 安装编译工具
sudo apt install build-essential libssl-dev libjsoncpp-dev uuid-dev zlib1g-dev libc-ares-dev libhiredis-dev g++-12 cmake git curl
- 配置gcc/g++
cd /usr/bin/
sudo rm gcc g++
sudo ln -s g++-12 g++
sudo ln -s gcc-12 gcc
# 确认版本
gcc --version
g++ --version
0x02 源码编译 数据库驱动
wget http://archive.ubuntu.com/ubuntu/pool/universe/m/mariadb-connector-c/mariadb-connector-c_3.0.3.orig.tar.gz
tar -zxf mariadb-connector-c_3.0.3.orig.tar.gz
cd mariadb-connector-c-3.0.3-src
# 修复一个小Bug：
vim cmake/ConnectorName.cmake
END() -> ENDIF()
vim CMakeLists.txt
# 在 PROJECT(mariadb-connector-c C) 下添加一行：
set(CMAKE_FIND_LIBRARY_SUFFIXES ".a")
mkdir build
cd build
cmake .. -DWITH_SSL=system -DWITH_EXTERNAL_ZLIB=ON -DWITH_STATIC=ON
make -j && sudo make install
0x03 源码编译 jsoncpp
因为libjsoncpp-dev 安装后， 没有.a 库，需要手动安装
git clone https://github.com/open-source-parsers/jsoncpp
cd jsoncpp/
mkdir build
cd build
cmake ..
make -j && sudo make install
# 作一下链接
sudo ln -s /usr/local/lib/libjsoncpp.a /usr/lib/x86_64-linux-gnu/libjsoncpp.a
# 使用ld验证链接时能找到
ld -ljsoncpp --verbose | grep libjsoncpp.a
0x04 安装drogon
1.下载源码
git clone https://github.com/drogonframework/drogon
cd drogon
git submodule update --init
1.安装 dg_ctl, 以动态方式安装。
因为脚手架命令工具只在本机执行，所以使用动态编译安装。
mkdir build
cd build
cmake ..
make -j && sudo make install
# 验证
dg_ctl help create
2.编译安装 dragon.a 静态库
- 修改CMakeLists.txt
找到 project(drogon) 上下分别添加 一行：
set(CMAKE_CXX_FLAGS "-fcoroutines -std=c++20 -static -static-libgcc -static-libstdc++")
project(drogon)
set(CMAKE_FIND_LIBRARY_SUFFIXES ".a")
执行编译
cd build
# 删除上一次编译的中间文件
rm -rf ./*
cmake .. -DBUILD_EXAMPLES=OFF -DBUILD_CTL=OFF -DCMAKE_BUILD_TYPE=Release
cmake 输出如下：

执行编译
make -j
sudo make install
编译成功
0x05 创建测试工程
cd $work_path
dg_ctl create project demo
- 修改main.cc 端口至 8000
- 修改CMakeListstxt
# 加两行
set(CMAKE_CXX_FLAGS "-fcoroutines -std=c++20 -static -static-libgcc -static-libstdc++")
project(demo CXX)
set(CMAKE_FIND_LIBRARY_SUFFIXES ".a")
# 注释掉最后一行 测试工程
#add_subdirectory(test)
- 执行编译
mkdir build
cd build
cmake ..
make -j
编译完成，有几行warning, 选择无视（静态代码中使用了调用动态库的API）
- 验证
ldd demo
not a dynamic executable # 说明这是一个静态编译的执行文件
- 执行程序
nohup ./demo &
- 访问接口：
curl localhost:8000
# 返回如下：
<html>
<head><title>404 Not Found</title></head>
<body bgcolor="white" text="black">
<center><h1>404 Not Found</h1></center>
<hr><center>drogon/1.8.4</center>
</body>
</html>

说明程序正常运行。
- 远程测试
把demo文件复制到另外一台 linux环境，进行上述验证，确保没有问题。
能进行到这里，说明已经可以快乐的玩耍了。
