cocos2d-x protobuf; cocos2dx protocol buffer
10482 ワード
昨日プロジェクトがprotocol bufferを使うことを知りました.今晩見て、protobufが本質的に情報表現プロトコル+編集、解析ライブラリであることを知りました.
linuxオープンソースソフトウェアはすべて1つのモードで、先に./configure --help > build.shあれらのものがあることを见て、更にconfigure make..
公式サイトのドキュメントに基づいて簡単なwriteを作って、readのtestは大体どんな状況なのかを理解します.
OK、ここまでprotocol bufferを使っています.次にcocos 2 dxにコンパイルします.
本質的にはiphone simulator、iOS、android ndkのいくつかのバージョンです(winは直接工事があって、私はまだ試していません)
ここでは、ネット上で既成の教育があります.http://www.giraffe-games.com/using-protobuf-protocol-buffers-on-iphone-ios/
https://github.com/dinote/protobuf-mobile-build(これはプラットフォーム間でプロファイルをコンパイルするので、後で修正して最適化します)

Protocol buffers are a flexible, efficient, automated mechanism for serializing structured data – think XML, but smaller, faster, and simpler. You define how you want your data to be structured once, then you can use special generated source code to easily write and read your structured data to and from a variety of data streams and using a variety of languages. As google puts it: “Protocol buffers are now Google’s lingua franca for data” and if it’s good enough for google, then it must be worth checking out!
We use protocol buffers to serialize persistant data for our IOS and Android games. Creating classes that persist data like shop, high scores, player preferences, achievements can be done in minutes with protobuf. And that why we ♥ protobuf!
This is not a protobuf usage tutorial, for that, you can check out the official documentation: https://developers.google.com/protocol-buffers/docs/overview. What you won’t find in the official documentation is how to make protobuf for iOS, and this is what this tutorial aims to explain. If you need to build protobuf for iOS, then read on
I’ll show you how to build protobuf library for armv7, armv7s, and i386 architecture, then merge those libraries together into a single fat library that can be used in iOS projects. This library will work on the simulator as well as on the device.
- We used protobuf2.4.1 (the last stable version at the time of writing) https://code.google.com/p/protobuf/downloads/list
- Command line tools can be updated by going to Xcode->Preferences.. then selecting the Downloads tab and selecting Command Line Tools
- to convert protobuf files into source code, you will need a protobuf compiler! You can build and install this compiler by going to protobuf directory and executing the following commands: $ ./configure $ make $ make check $ make install
To build the ios protobuf static library copy this script into protobuf directory and name it build-proto-ios.sh, then execute this to give the file execute privilegies:
$ chmod a+x ./build-proto-ios.sh $ ./build-proto-ios.sh
Go make a cup of coffie, this will take a few minutes You can also download the precompiled fat ios library from here.
After the compilation is done you will see a new folder under protobuf root called: ios-build. This folder contains libprotobuf-lite.a. This is a static library for iOS.
To import libprotobuf-lite.a into Xcode, just right click on a project directory where you want to import the library, from the drop-down list choose “Add Files to project-name…” and add libprotobuf-lite.a library.
You still need to tell Xcode where to look for protobuf headers. To do this go to your project target build settings and under “Header Search Paths” add the path to protobuf-base-folder/src. The “protobuf-base-folder” being the folder in which you have the protobuf library from google.
option optimize_for = LITE_RUNTIME; at the start of your proto definition file.
For a tutorial on how to use protobuf, it’s best to check out googles official documentation: https://developers.google.com/protocol-buffers/docs/overview
Happy protobuffing.
If you got any suggestions or question, feel free to ask/suggest!

1、 のxcodeバージョンは6.1です.このバージョン はcrossコンパイラアドレスに します.エラーが した 、makeのときにヒントを え、 しやすいです.
2、 は は1つのliteライブラリをコンパイルするだけで、あれらのcompiler、test... たちとは ないので、make libprotobuf-liteを います.Laはその する16のファイルをコンパイルします.エラーの はずっと いです.△ で したように、まずprotocをコンパイルしてインストールする はありません.
ok,cross compile over;
1、next we will try how to use this lib in Xcode (cocos2dx).
これはすでに して、 なcocos 2 dx はすでにアップロードして、 を てurlをダウンロードします.ダウンロード 、 できます. はコンソールメッセージを してください.

2、Android version protobuf
は がありましたが、まだandroidを る がありません.
Androidの でiOSのように にlibprotobufをコンパイルすることができます.a、また でこれを び します.a,しかし、これは には であることに づいたので、 ったほうがいい.ccファイルが に わったAndroid.mk.どうせコンパイルするaファイルもこの に います.
のやり はsrc/googleディレクトリを projに てることです.Android/jni/ はAndroid.mkは すればいいです.linuxの でMakefileを って を します( はvsとxcodeはすべて じです)、このようにMakefileの で したファイルだけがコンパイルされるので、 のgoogle/ディレクトリの のものは のことは にしません.

3、to simplify these steps
このようにして、みんなはすでに っていて、 はprotobuf-liteにとって、いくつかのファイルの だけで、その でuもこのいくつかのファイルを することはできません.だからいっそ の として きずり んでしまった.しかもすべてcppコードで、プラットフォームにまたがって、メンテナンスしやすくて、“お さんは と のコードを する はありません.”
for the last ,I will upload a cocos2dx project that include iOS/simulator/android versions.
