### Before Creating the Bug Report - [X] I found a bug, not just asking a question, which should be created in [GitHub Discussions](https://github.com/apache/rocketmq-clients/discussions). - [X] I have searched the [GitHub Issues](https://github.com/apache/rocketmq-clients/issues) and [GitHub Discussions](https://github.com/apache/rocketmq-clients/discussions) of this repository and believe that this is not a duplicate. - [X] I have confirmed that this bug belongs to the current repository, not other repositories of RocketMQ. ### Programming Language of the Client C++ ### Runtime Platform Environment Windows 11 23H2 ### RocketMQ Version of the Client/Server latest repository ### Run or Compiler Version Visual Studio 2022 CMake 3.28.3 ### Describe the Bug An error occured when building c++ version of rocket clients. gRPC v1.46.3 gflags v2.2.2 openssl v3.3.1  ### Steps to Reproduce follow the official building instructions. ### What Did You Expect to See? target rocketmq_shared successfully built ### What Did You See Instead? error LNK2019 ### Additional Context I found that the target 'rocketmq_shread' uses header files from OpenSSL libs requried by the building instruction while it linked to 'crypto.lib' shipped by google gRPC which actually bulit from boringssl. The unfound symbol EVP_MD_get_szie from TlsHelper.cpp comes from macro EVP_MD_size, which, in the context of openssl, expands to the fucntion EVP_MD_get_size. I know little about openssl or boringssl, but I found that the symbol EVP_MD_size does exists in 'crypto.lib'. So I use the code to bridge the call the EVP_MD_size function. ` #undef EVP_MD_size extern "C" { int EVP_MD_size(const EVP_MD *md); } ` The target can be built successfully, but I'm not sure if this can work properly. -- This is an automated message from the Apache Git Service.
