Google PROTOBUF development environment configuration under windows

Recent project requirements, client and Server network communication protocol transfer using Google Protobuf RPC. For Protobuf, previously only know this thing, know what it does, and has been very admired, but never studied, recently just take advantage of the project opportunity, study hard.

This article focuses on configuring the Google PROTOBUF development environment under Windows with vs2012.

I. Preparatory work:

1.windows7 or other Windows systems.

2.Visual Studio 2012 or other version vs.

3.PROTOBUF: I am using the latest version of Protobuf (protobuf-2.6.1).

Under Windows, you need to download two packages:

protobuf-2.6.1.tar.bz2 (protobuf all the source code is inside, use it to compile into Lib library)

Protoc-2.6.1-win32.zip (connotation protoc.exe, the text used to compile proto files into the target language (C++,java,python), is a format defined by Google Protobuf. in fact, this file is not necessary, compile protobuf-2.6.1.tar.bz2 will generate this EXE)

Go to the official website to download Protobuf source code and compile tool: Https://developers.google.com/protocol-buffers/docs/downloads

Then unzip: my local path is D:\protobuf-2.6.1

Two. Configure the environment:

1. Enter D:\protobuf-2.6.1\vsprojects, run Protobuf.sln with vs2012, and build solution.

These people will, I will not wordy.

Then you will find that there is a lot of content in the D:\protobuf-2.6.1\vsprojects\Debug directory, the most important of which is:Libprotobuf.lib,Libprotobuf-lite.lib,Libprotoc.liband theProtoc.exe

2.d:\protobuf-2.6.1\examples would have been an example of that, we personally practice, to define a proto in this directory:

Package Tutorial;message Person {  Required String name = 1;  Required Int32 age = 2;  Optional String email = 3;}

then run Protoc.exe using CMD to generate our target language format (c + +).

CD D:\protobuf-2.6.1\vsprojects\Debug

d:\protobuf-2.6.1\vsprojects\debug>protoc-i=d:\protobuf-2.6.1\examples--cpp_out=d:\protobuf-2.6.1\ Examples D:\protobuf-2.6.1\examples\person.proto

You can then see that the person.pb.h and person.pb.cc files are generated.

3. We use vs2012 to create a new empty project, select Properties, configure:

Under Configuration Properties , click the general , Add directory to the right, and import the path D:\protobuf-2.6.1\src

Click the linker 's General , the right side of the additional library directory , import this path D:\protobuf-2.6.1\vsprojects\Debug

Three. Start one of the simplest projects

Well, everything is ready, it's time to write the code, and we'll do the simplest input and output. Create a new main.cpp, and then copy the previously generated person.pb.h and person.pb.cc into the project and add it to the project.

#include <iostream> #include "person.pb.h" using namespace Std;using namespace Tutorial;int main () {person person; Person.set_name ("Flamingo");   Person.set_age ();   Cout<<person.name () <<endl;cout<<person.age () <<endl;system ("pause"); return 0;}

Some people say it works, but my side is not, mainly

Find the reason online, and finally found that need to add two lines in the code:

#pragma comment (lib, "Libprotobuf.lib") #pragma comment (lib, "Libprotoc.lib")

will be able to run normally:
