如何才能在Eclipse下写cocos2d程序

贴： cocos2d-x-3.0rc0/templates/cpp-template-default/proj.android/README.MD


## Prerequisites:


* Android NDK
* Android SDK **OR** Eclipse ADT Bundle
* Android AVD target installed


## Building project


There are two ways of building Android projects.


1. Eclipse
2. Command Line


### Import Project in Eclipse


#### Features:


1. Complete workflow from Eclipse, including:
* Build C++.
* Clean C++.
* Build and Run whole project.
* Logcat view.
* Debug Java code.
* Javascript editor.
* Project management.
2. True C++ editing, including:
* Code completion. 
* Jump to definition.
* Refactoring tools etc. 
* Quick open C++ files.




#### Setup Eclipse Environment (only once)




**NOTE:** This step needs to be done only once to setup the Eclipse environment for cocos2d-x projects. Skip this section if you've done this before.


1. Download Eclipse ADT bundle from [Google ADT homepage](http://developer.android.com/sdk/index.html)


   **OR**


   Install Eclipse with Java. Add ADT and CDT plugins.


2. Only for Windows
    1. Install [Cygwin](http://www.cygwin.com/) with make (select make package from the list during the install).
    2. Add `Cygwin\bin` directory to system PATH variable.
    3. Add this line `none /cygdrive cygdrive binary,noacl,posix=0,user 0 0` to `Cygwin\etc\fstab` file.
   
3. Set up Variables: 
1. Path Variable `COCOS2DX`: 
* Eclipse->Preferences->General->Workspace->**Linked Resources**
* Click **New** button to add a Path Variable `COCOS2DX` pointing to the root cocos2d-x directory.


2. C/C++ Environment Variable `NDK_ROOT`: 
* Eclipse->Preferences->C/C++->Build->**Environment**.
* Click **Add** button and add a new variable `NDK_ROOT` pointing to the root NDK directory.
* Only for Windows: Add new variables **CYGWIN** with value `nodosfilewarning` and **SHELLOPTS** with value `igncr`

4. Import libcocos2dx library project:
1. File->New->Project->Android Project From Existing Code.
2. Click **Browse** button and open `cocos2d-x/cocos2dx/platform/android/java` directory.
注：在3.0rc的这个SDK中，该项目的具体目录在：cocos2d-x-3.0rc0/cocos/2d/platform/android/java下面。


3. Click **Finish** to add project.

#### Adding and running from Eclipse


 


1. File->New->Project->Android Project From Existing Code
2. **Browse** to your project directory. eg: `cocos2d-x/cocos2dx/samples/Cpp/TestCpp/proj.android/`
3. Add the project 
4. Click **Run** or **Debug** to compile C++ followed by Java and to run on connected device or emulator.




### Running project from Command Line


    $ cd cocos2d-x/samples/Cpp/TestCpp/proj.android/
    $ export NDK_ROOT=/path/to/ndk
    $ ./build_native.sh
    $ ant debug install


If the last command results in sdk.dir missing error then do: 


    $ android list target
    $ android update project -p . -t (id from step 6)
    $ android update project -p cocos2d/cocos/2d/platform/android/java/ -t (id from step 6)




Follow这个流程，基本上还是无法在Eclipse中正常编译通过，哪怕是TestCpp。
但是workaround是，可以在cocos2d目录下调用coco compile命令进行编译，然后在eclipse中导入。
最后发现在： http://www.ityran.com/archives/1062 有关如何在Eclipse中开发的guide，经测试，可以成功。
