Prepare the environment to publish and subscribe to messages with the RocketMQ SDK for C++-ApsaraMQ for RocketMQ(RocketMQ)-阿里云帮助中心

To use the SDK for C++ to publish and subscribe to messages, prepare your environment.

Prerequisites

Install SCons. For more information, see Install SCons.
SCons requires Python 3.5 or later. For more information, see Install Python.
Install Visual Studio 2015 or later. For more information, see Install Visual Studio.

Note
Visual Studio is required only for Windows systems. These instructions use Visual Studio 2019 as an example.

Install the SDK for C++

Windows

Download and extract the SDK on-premises. For the SDK download link, see release notes.
From the directory where you extracted the SDK, run the following command to build the project.
```
scons
```
After the build succeeds, copy the include and lib folders from the SDK directory to your on-premises C++ project's directory.
Configure the project properties in Visual Studio. Right-click the project and select Properties.
- Set Additional Include Directories
  
  On the project properties page, select Configuration Properties > C/C++ > General > Additional Include Directories, and set Additional Include Directories to the path of the include folder that you copied in Step 3.
- Set Additional Library Directories
  
  On the Project Properties page, select Configuration Properties > Linker > General > Additional Library Directories, and set Additional Library Directories to the path of the lib folder that you copied in Step 3 and the path of the lib\windows\{Platform Directory} folder. The {Platform Directory} placeholder depends on your operating system: use AMD64 for a 64-bit OS and I386 for a 32-bit OS.
- Set Additional Dependencies
  In the project properties page, select Configuration Properties > Linker > Input > Additional Dependencies, and add the following content to Additional Dependencies.
```
