GitHub user cgeffect edited a discussion: 如何链接rocketmq静态库?
系统: linux centos
版本: 5.0.1
-rw-r--r-- 1 xxx algorithm 200M Apr 16 22:11 librocketmq.a
-rwxr-xr-x 1 xxx algorithm 61M Apr 16 22:11 librocketmq.so
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, 报了很多absl, grpc, opencensus未定义的符号.
rocketmq依赖的三方静态库不是直接打包进librocketmq.a的吗? 还需要单独链接吗?

通过ldd 命令查看动态库的依赖, 发现libssl.so.1.1 和libcrypto.so.1.1 依赖的是动态库,
怎么才能使rocketmq依赖静态库呢?
