# Windows MQTT库安装指南
|
||
|
||
## 方法1: 使用vcpkg (推荐)
|
||
|
||
### 1. 安装vcpkg
|
||
```cmd
|
||
git clone https://github.com/Microsoft/vcpkg.git
|
||
cd vcpkg
|
||
.\bootstrap-vcpkg.bat
|
||
```
|
||
|
||
### 2. 安装MQTT库
|
||
```cmd
|
||
.\vcpkg install paho-mqtt:x64-windows
|
||
.\vcpkg install paho-mqttpp3:x64-windows
|
||
.\vcpkg install nlohmann-json:x64-windows
|
||
```
|
||
|
||
### 3. 集成到CMake
|
||
```cmd
|
||
.\vcpkg integrate install
|
||
```
|
||
|
||
### 4. 修改CMake命令
|
||
在构建时添加vcpkg工具链：
|
||
```cmd
|
||
mkdir build
|
||
cd build
|
||
cmake .. -DCMAKE_TOOLCHAIN_FILE=[vcpkg根目录]/scripts/buildsystems/vcpkg.cmake
|
||
cmake --build .
|
||
```
|
||
|
||
## 方法2: 手动编译
|
||
|
||
### 1. 编译Paho MQTT C库
|
||
```cmd
|
||
git clone https://github.com/eclipse/paho.mqtt.c.git
|
||
cd paho.mqtt.c
|
||
mkdir build
|
||
cd build
|
||
cmake .. -DPAHO_BUILD_STATIC=TRUE -DPAHO_BUILD_SHARED=FALSE
|
||
cmake --build . --config Release
|
||
cmake --install . --prefix C:/mqtt/c
|
||
```
|
||
|
||
### 2. 编译Paho MQTT C++库
|
||
```cmd
|
||
git clone https://github.com/eclipse/paho.mqtt.cpp.git
|
||
cd paho.mqtt.cpp
|
||
mkdir build
|
||
cd build
|
||
cmake .. -DPAHO_MQTT_C_PATH=C:/mqtt/c -DPAHO_BUILD_STATIC=TRUE
|
||
cmake --build . --config Release
|
||
cmake --install . --prefix C:/mqtt/cpp
|
||
```
|
||
|
||
### 3. 修改CMakeLists.txt
|
||
添加库路径：
|
||
```cmake
|
||
set(CMAKE_PREFIX_PATH "C:/mqtt/cpp;C:/mqtt/c")
|
||
find_package(PahoMqttCpp REQUIRED)
|
||
```
|
||
|
||
## 验证安装
|
||
|
||
运行以下命令验证：
|
||
```cmd
|
||
cd build
|
||
cmake ..
|
||
```
|
||
|
||
如果没有错误，说明MQTT库已正确配置。
|
||
|
||
## 使用示例
|
||
|
||
在您的代码中导入MQTT：
|
||
```cpp
|
||
#include <mqtt/async_client.h>
|
||
#include "mqtt.hpp"
|
||
|
||
// 创建MQTT客户端
|
||
auto mqttClient = std::make_unique<custom::MqttClient>("localhost", 1883, "test_client");
|
||
mqttClient->connect();
|
||
mqttClient->subscribe("test/topic");
|
||
```
