google protobuf
官网
安装
vs2015 编译 google protobuf 3.5.1
下载:
protobuf 3.5.1
cmake
编译
使用 VS2015开发人员命令提示:
进入 protobuf 的目录:
首先创建一个 building
文件夹,并创建tmp
,x86_debug
子文件夹:
VS2015开发人员命令提示进入上面的 tmp
目录,执行:
cmake -G "NMake Makefiles" -DCMAKE_BUILD_TYPE=Debug -Dprotobuf_BUILD_TESTS=OFF -Dprotobuf_BUILD_SHARED_LIBS=ON -DCMAKE_INSTALL_PREFIX=../x86_debug ../../cmake
等待cmake generate结束后,执行:
nmake
nmake install
如果想要使用 release 版本,只需要更改上述的命令行为:-DCMAKE_BUILD_TYPE=Release
。
查看一下版本号,到bin文件目录下执行:
.\protoc.exe --version
libprotoc 3.5.1
VS2015 工程环境配置
配置包含目录和库目录
增加预处理器定义
增加连接器依赖
禁用SDL检查
不使用预编译头
添加dll路径
用下试试
新建文件:addressbook.proto
:
syntax = "proto2";
package tutorial;
message Person {
required string name = 1;
required int32 id = 2;
optional string email = 3;
enum PhoneType {
MOBILE = 0;
HOME = 1;
WORK = 2;
}
message PhoneNumber {
required string number = 1;
optional PhoneType type = 2 [default = HOME];
}
repeated PhoneNumber phones = 4;
}
message Addressbook {
repeated Person people = 1;
}
在bin目录下使用命令行:
.\protoc.exe --cpp_out=. .\addressbook.proto
生成文件:
将上面的的文件复制到 VS2015 的工程当中,
写文件:
#include
#include
#include
#include "addressbook.pb.h"
using namespace std;
void PromptForAddress(tutorial::Person* person) {
cout << "Enter person ID number: ";
int id;
cin >> id;

getline(cin, *person->mutable_name());
cout << "Enter email address (blank for none): ";
string email;
getline(cin, email);
if (!email.empty())
person->set_email(email);
while (true) {
cout << "Enter a phone number (or leave blank for finish): ";
string number;
getline(cin, number);

}
}
int main(int argc, char* argv[]) {
GOOGLE_PROTOBUF_VERIFY_VERSION;
if (argc != 2) {
cerr << "Usage: " << argv[0] << "ADDRESS_BOOK_FILE " << endl;
return -1;
}
tutorial::Addressbook address_book;
fstream input(argv[1], ios::in | ios::binary);
if (!input)
cout << argv[1] << ": File not found. Creating a new file. " << endl;

fstream output(argv[1], ios::out | ios::trunc | ios::binary);
if (!address_book.SerializeToOstream(&output)) {
cerr << "Failed to write address book. " << endl;
return -1;
}
google::protobuf::ShutdownProtobufLibrary();
return 0;
}
读文件:
#include
#include
#include
#include "addressbook.pb.h"
using namespace std;
void ListPeople(const tutorial::Addressbook& address_book) {
for (int i = 0; i < address_book.people_size(); ++i) {

const tutorial::Person::PhoneNumber& phone_number = person.phones(j);
switch (phone_number.type()) {
case tutorial::Person::MOBILE:
cout << " Mobile phone#: ";
break;
case tutorial::Person::HOME:
cout << " Home phone#: ";
break;
case tutorial::Person::WORK:
cout << " Work phone#: ";
break;
}
cout << phone_number.number() << endl;
}
}
}
int main(int argc, char** argv) {
GOOGLE_PROTOBUF_VERIFY_VERSION;
if (argc != 2) {
cerr << "Usage: " << argv[0] << "ADDRESS_BOOK_FILE " << endl;
return -1;

cerr << "Failed to parse address book. " << endl;
return -1;
}
ListPeople(address_book);
google::protobuf::ShutdownProtobufLibrary();
return 0;
}
VS2015 加入命令行参数的方法:
