COCOS2DX porting Eclipse, developed with the NDK, implementing the Discard Vs,eclipse write C + + code

1. Disclaimer: Readers of this blog post are applicable to the people who compiled success in Eclipse to run the COCOS2DX project

2. The game engine I use is the cocos2dx2.2.2 version

The 3.NDK version is android-ndk-r8d

4. I ported my COCOS2DX project to eclipse, opened the class I wrote in VS, and found that some of the classes have the following, which is not really a problem, just the project I'm importing

Can't find something, you turn this class off, run the program to find the error, but the project shows that there is no error, then you turn off the project, recompile is available

5. Write here, someone may ask, since the above solution has been provided, it is not good, but you do not think that will be very tired, a little modification of things to shut down the project, re-come,

The key is to report such errors, it will make you suspect that you fill in the authenticity of the code, I would like to introduce a method, is to discard the COCOS2DX project comes with the cocos2dx,classes and other folders, directly compiled with the NDK, so you can debug

6. Copy your Classes folder to the Jni folder and modify the Android.mk file

For

The reason for this is very simple, we look at the directory structure will be found in the ANDROID.MK directory structure is based on the JNI root directory, the original classes is in the first two directories of the JNI directory, now your directory structure changed, the configuration information of course change

7. Of course, the change here is still very far from our goal, right click on your project, select Properties, select C/S build modified as follows

The purpose of this step is to debug

8. Expand C + + Build selection tool Chain Editor with the following configuration information

Please note that the key point in this drop-down box is the no toolchain option, congratulations you are lucky, because there may be the following situation

Did you find out? No toolchain option is not, this is a tragedy of a situation, is also a blogger encountered, but also let me make up my mind to write this blog, when encountered, your entire project is wasted, no matter how you modify (may be I do not understand) can not compile successful projects, the project error is as follows:

9. This error, according to my understanding is that the key command can not be found, there is a compilation problem, this problem Bo master is resolved:

A. First of all, you may have never paid attention to the. cproject file in the Proj.android folder under your project. This file is actually a configuration file for the project, and when we make a change to the project configuration, the information is stored in this file, no The toolchain option does not have the problem that appears here, the configuration file does not have, then I attach a correct configuration file:

Replace, update the project, see again, found no toolchain option appears, congratulations on your success is very close, compile the project, or an error occurred

It means the Ndk_module_path is not set.

2. Here we do not set Ndk_module_path, because set it will let us not debug C + + code, solve the above problem is: the compilation process needed to copy the library to the system default Ndk_module_path, follow me to do
4. Copy these 4 directories under the cocos2d-2.1rc0-x-2.1.3 directory cocos2dx,CocosDenshion,extensions,external to your ndk's sources directory, take my computer for example, is/android/android-ndk-r8e/sources
6. Copy all of the cocos2d-2.1rc0-x-2.1.3/cocos2dx/platform/third_party/android/prebuilt directories into the sources directory of the NDK
8. So we copy the directory to the NDK's sources directory. cocos2dx,CocosDenshion,extensions,external, libcurl,libjpeg,libpng,libtiff,libwebp
10. Back to eclipse, project->build all again, should compile successfully

Here, I quoted the http://blog.csdn.net/tt5267621/article/details/8940768 method.

Now we should compile again and it will be successful.
