[I] 编译失败 (brpc)
707state opened a new issue, #2761:
URL: https://github.com/apache/brpc/issues/2761
**Describe the bug (描述bug)**
在Arch Linux上用g++或者clang++都无法通过编译，且报错不同。
g++:
brpc/src/brpc/baidu_master_service.h:91:24: error: cannot declare field ‘brpc::BaiduMasterService::_default_response’ to be of abstract type ‘brpc::SerializedResponse’
91 | SerializedResponse _default_response;
/brpc/serialized_response.h:29:7: note: because the following virtual functions are pure within ‘brpc::SerializedResponse’:
29 | class SerializedResponse : public ::google::protobuf::Message {
...
clang++
brpc/src/brpc/serialized_request.h:54:32: error: only virtual member functions can be marked 'override'
54 | bool IsInitialized() const override;
brpc/src/brpc/serialized_request.h:70:61: error: only virtual member functions can be marked 'override'
70 | void MergeFrom(const ::google::protobuf::Message& from) override
...
去除override之后为
./src/brpc/serialized_request.h:60:32: error: ‘google::protobuf::Metadata brpc::SerializedRequest::GetMetadata() const’ marked ‘override’, but does not override
60 | ::google::protobuf::Metadata GetMetadata() const override;
**To Reproduce (复现方法)**
按照 https://brpc.apache.org/docs/getting_started/ 网站上用config_brpc.sh的方法进行编译
**Expected behavior (期望行为)**
应当正常编译
**Versions (各种版本)**
OS: Arch Linux
Compiler: g++/clang++
brpc: master
protobuf: 27.3-2
grpc: 1.65.5-1

protobuf版本的问题吧，换成protobuf 3试试

应该是protobuf版本问题。
这类问题我遇到过几次，最近一次是在arch上编译，系统默认安装的pb是v28，出现类似问题，后面源码更新到29还是类似报错，换到3.20.x才顺利编译
