破了一半。`MessageListener#consume`改好后可以消费了，但是日志里还是报错no topic route

cpp动态库方法
我编译出来的动态库和静态库的大小

请问一下: librocketmq.a依赖的静态库都是已经打进了librocketmq.a里面了吧, 工程中如果使用的话,

已经编译出了librocketmq.a, 还有libproto.a和libopencensus_proto.a,
工程链接只链接librocketmq.a不行,

我的项目中已经使用了protobuf3.20, 编译rocketmq时, 使用的grpc是1.462, grpc内部使用的protobuf是3.19.0,
目前确认时因为两个protobuf版本不同, 导致的crash. 有什么办法可把rocketmq里的依赖的静态库完全和工程里的静态库符号完全隔离?
通过这种方式吗?

5.x版本在编译的时候可以禁用protobuf吗

又确认了一遍, 和topic是否提前在控制台注册与否没关系, 是rocketmq::Producer析构导致的crash

是和[rocketmq-client-nodejs](https://github.com/apache/rocketmq-client-nodejs)功能一样的，只是升级了下版本兼容问题，如果可以，你可以直接看源码了解下

可以确认下rocketmq dashboard配置的namesrv地址是不是对的，dashboard有报错日志吗？一般遇到这种【No topic route
info】就是namesrv地址没配对或者topic根本没创建

官方文档比较坑，甚至没有docker的部署示例。。。
rocketmq5.x引入了proxy，需要开放一下端口，不然访问不了。
# 1.先简单安装一下，8081是grpc访问端口，8080是remoting访问（如果需要）
docker run -d \
