   > Hello, @hanzhonghua0927 @zengxiaobai
   > The Cgo SDK will link the dynamic CPP library as default, and the dependencies such as the zlib are linked dynamically.
   > if you want to use the CPP static library, the Zlib and libstdc++ libraries need to be linked manually, please follow 3 steps:
   > 
   > 1. remove the dynamic library in your LDPATH(default: /usr/local/lib)
   > 2. change the LDFLAGs in the go SDK from "cgo LDFLAGS: -L/usr/local/lib -lrocketmq" to "cgo LDFLAGS: -L/usr/local/lib -lz -l stdc++ -lrocketmq"
   > 3. build your project directly without any building flags.
   > 
   > please have a try.
   
   I try like this:
   step1: remove librocketmq.so from /usr/local/lib, mv librocketmq.a to /usr/local/lib/
   step2:  install zlib-static libstdc++-static 
   step3: copy  libz.a libstdc++.a to /usr/local/lib
   step4:  change  core/producer.go  core/message.go  core/cfuns.go  core/pull_consumer.go  core/push_consumer.go  FROM
   #cgo LDFLAGS: -L /usr/local/lib/    TO  -L/usr/local/lib/ -lrocketmq -lz -lstdc++ (-lrocketmq)
   step5: go build
   
   ERRORS: 
   ```
