ubuntu22.04安装使用 protobuf 23.3静态库

https://github.com/protocolbuffers/protobuf/

下载最新的release版本，23.3

必须需要依赖的第三方库 abseil，utf8_range

mkdir build

cd build

cmake -DCMAKE_BUILD_TYPE=DEBUG  -DCMAKE_INSTALL_PREFIX=/usr/local -Dprotobuf_BUILD_SHARED_LIBS=OFF -Dprotobuf_WITH_ZLIB=OFF -Dprotobuf_BUILD_TESTS=OFF ..

make

sudo make install

或直接修改CmakeList.txt 添加/修改以下内容

set(protobuf_VERBOSE ON) #debug信息
set(protobuf_BUILD_TESTS  OFF)#不编译test
set(protobuf_WITH_ZLIB  OFF)  #不使用zlib
set(protobuf_WITH_ZLIB_DEFAULT OFF)#不使用zlib
set(protobuf_BUILD_SHARED_LIBS  OFF)#静态库
set(protobuf_BUILD_SHARED_LIBS_DEFAULT  OFF)#静态库
set(CMAKE_INSTALL_PREFIX /usr/local)#安装路径

如果要建立动态库，依赖的abseil 最好也是动态库.

安装后使用的方法，在target_link_libraries里，需要先写protobuf，然后rtf8_range，最后才是absl。 顺序不可以改变，因为protobuf要依赖后两个，rtf8_range要依赖absl

absl把所有的都一起贴上了

student.proto

syntax = "proto3";
package student;// 定义联系人message
message StudentInfo {string name = 1;bool isMale = 2;int32 age = 3;
}

student.pb.cc和student.pb.h 是用cmake生成的

proto_test.cpp

#include <iostream>
#include "student.pb.h"#include <google/protobuf/compiler/plugin.h>int main(int argc,char** argv) {std::string data_str;{
//         使⽤ PB 进⾏序列化，并将结果打印出来。student::StudentInfo _student;_student.set_name("小豪豪");_student.set_ismale(true);_student.set_age(20);if (!_student.SerializeToString(&data_str)) {std::cerr << "序列化_student失败！" << std::endl;return -1;}std::cout << "序列化_student成功，结果：" << data_str << std::endl;}{// 使⽤ PB 进⾏反序列，解析出联系⼈信息并打印出来。student::StudentInfo _student;if (!_student.ParseFromString(data_str)) {std::cerr << "反序列化失败！" << std::endl;return -1;}std::cout << "反序列化成功！" << std::endl;std::cout << "name:" << _student.name() << std::endl;std::cout << "ismale:" << _student.ismale() << std::endl;std::cout << "age:" << _student.age() << std::endl;}return 0;
