Protobuf调用Utf8DebugString()发生coredump问题

本文主要是介绍Protobuf调用Utf8DebugString()发生coredump问题，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

Protobuf调用Utf8DebugString()发生coredump

概述

-> % ./test                                            
GOOGLE_PROTOBUF_VERSION:3012003
terminate called after throwing an instance of 'std::system_error'what():  Unknown error -1
[1]    3303214 abort (core dumped)  ./test

CMakeLists.txt

project(test)
include_directories(./${THIRD_PART_PATH}/protobuf/protobuf_3.12.3/include${THIRD_PART_PATH}
)
link_directories(${THIRD_PART_PATH}/protobuf/protobuf_3.12.3/lib
)
add_executable(test test.cpp example.pb.cc planning.pb.cc RawInsParkingSpace.pb.cc)
target_link_libraries(test protobuf)

src

#include <iostream>
#include <fstream>#include "planning.pb.h"void test2() {Planning pts;pts.set_tick(152);pts.set_timestamp(155);std::cout << pts.tick() << std::endl;std::cout << pts.Utf8DebugString() << std::endl;
}int main() { std::cout <<"GOOGLE_PROTOBUF_VERSION:" << GOOGLE_PROTOBUF_VERSION << std::endl;test2(); return 0;
}

原因

编译时需要链接 pthread

target_link_libraries(test protobuf pthread)
