> 我和思为可以参加录制吗？本来之前也想约嵇斌大神的 荣幸，已经有点期待思为的声音了 :-)

这一年通过收听《开源面对面》二十多期的节目，让我更加坚信了两件事情：参与开源有时候并不一定需要在代码上、或者软件上；内容的开源、知识的开源同样精彩。以及参与开源任何时候都不会为时过晚，需要的只是能开始。 在此，也要非常感谢 Rick，能够邀请我参与了一期节目的录制，这让我对播客尤其是开源内容的播客有了更深入的了解，也让我对自己参与开源这件事情有了新的认识。 相信未来，《开源面对面》能够给我们带来更多新的故事和新的惊喜！

Not reproduce it under centos:7 with devtoolset-9. I run the sdk_simple success. @Renekton Could you share more information, e.g. how do you using devtoolset-9, I usually use `source /opt/rh/devtoolset-9/enable` to...

> Milvus already use conan. Feel free to discuss with @jiaoew1991 Yes, I see that on master, so I'd like to see conan is the 1st choice for cpp sdk...

By default, the milvus-cpp-sdk are compiled with static lib. So you need to link grpc++ again in your project. I good solution is to switch to shared library for milvus-cpp-sdk....

This is a linker/loader question. For gcc toolchain, you could add `RPATH` by linker with `-Wl,-rpath=/usr/local/lib` for your case, e.g.: `g++ main.cpp -I /usr/local/include -L /usr/local/lib -l milvus_sdk -o output...

IMO, this is a code integration issue, we do tests/examples with CMake, and this is smooth for application integration with milvus-sdk-cpp, but if guys use `GNU Makefile` to manually compile/link...
