2、下载jar包
主要依赖:rocketmq-client-3.5.8.jar、rocketmq-common-3.5.8.jar、rocketmq-3.5.8-remoting-3.5.8.jar三个包。
3、参考代码,生产者

c/c++版本

在github上由广大用户维护的几个版本:
1、可用资源
a、https://github.com/hooligan520/rocketmq-client4cpp-linuxhooligan 维护一个可用的版本,主要支持linux平台。推荐使用。
b、https://github.com/lehoon/rocketmq-client4cpp-linux 主要是修改文件编码为UTF-8,后续继续维护更新。
2、下载代码后,通过sh build.sh编译出lib在release文件夹下。
