ZW007 opened a new issue #14673:
URL: https://github.com/apache/pulsar/issues/14673


   **Describe the bug**
   Could not get c++ client built on my Ubuntu 18.04
   **To Reproduce**
   Follwed steps from [official 
tutorial](https://pulsar.apache.org/docs/en/next/client-libraries-cpp/#compilation)
   1. `git clone https://github.com/apache/pulsar`
   2. `apt-get install cmake libssl-dev libcurl4-openssl-dev liblog4cxx-dev \
     libprotobuf-dev protobuf-compiler libboost-all-dev google-mock 
libgtest-dev libjsoncpp-dev`
   3. `# libgtest-dev version is 1.18.0 or above`
    `cd /usr/src/googletest`
    `sudo cmake .`
    `sudo make`
    `sudo cp ./googlemock/libgmock.a ./googlemock/gtest/libgtest.a /usr/lib/`
   4. `cd /usr/src/gmock`
   ` sudo cmake .`
   ` sudo make`
   ` sudo cp libgmock.a /usr/lib`
   5. `cd pulsar-client-cpp`
    `cmake .`
     **make** 
    
   Could not **make**, it says: ` error: ‘class 
google::protobuf::FileDescriptorSet’ has no member named ‘ByteSizeLong’; did 
you mean ‘ByteSize’?`     ` 
lib/CMakeFiles/PULSAR_OBJECT_LIB.dir/build.make:1605: recipe for target 
'lib/CMakeFiles/PULSAR_OBJECT_LIB.dir/ProtobufNativeSchema.cc.o' failed
   `
   
   **Error**

   **Try to fix the error**
   As suggsted, changed `ByteSizeLong` to `ByteSize` in 
./pulsar-client-cpp/lib/ProtobufNativeSchema.cc code, then got new error:
   
   `PaddingDemo.proto:25:12: Explicit 'optional' labels are disallowed in the 
Proto3 syntax. To define 'optional' fields in Proto3, simply remove the 
'optional' label, as fields are 'optional' by default.
   tests/CMakeFiles/main.dir/build.make:68: recipe for target 
'generated/tests/PaddingDemo.pb.cc' failed`

   **Desktop (please complete the following information):**
    - OS: [Ubuntu 18.04]
   
   **Additional context**
   I guess it has to do with protobuf version, but could not find any more 
information. Thank you!
