Adding chipmunk to new project

cocos2d-x C++
#1

First, Great job on cocos2d-x.

I’m a relative noob developing on the iPhone and this is a great way to use what I’m learning on android.

I’ve managed to compile and run the tests, helloworld and create a new project named Cocos2dSimpleGame.

I’m trying to add chipmunk to no success.

I’ve added…

chipmunk
to the Android.mk

and…

LOCAL_C_INCLUDES := $(LOCAL_PATH)/…/…/…/…/cocos2dx $(LOCAL_PATH)/…/…/…/…/cocos2dx/include $(LOCAL_PATH)/…/…/…/tests $(LOCAL_PATH)/…/…/…/… $(LOCAL_PATH)/…/…/… $(LOCAL_PATH)/…/…/…/chipmunk/include/chipmunk

  1. it is used for ndk-r4
    LOCAL_LDLIBS := ~~L$/…/…/libs/armeabi ~~lcocos2d ~~llog ~~lchipmunk

to the HelloWorld/Android.mk

and added…

System.loadLibrary(“chipmunk”);

to Cocos2dSimpleGame.java

It builds fine, but when I try to run the app on the device I keep getting “Cocos2dSimpleGame has stopped unexpectedly, try again”

What am i missing here?

Thanks in advance

Pat

Sorry. I apologize for the delay.
Ming is our chief programmer on android, but he is on maternity leave with his wife in this whole week.
I have to facing all tech support requirements in China and beyond, more than 50 active developers. so busy…
Well, I will create the android project and try to add chipmunk dependance. But I’m not very familiar to android, it make take some times.

well, I follow your steps, and find a trap here, in Cocos2dSimpleGame.java
I guess your code may like this:

    static {
        System.loadLibrary("cocos2d");
        System.loadLibrary("helloworld");
        System.loadLibrary("chipmunk");
    }

You may added chipmunk at the end. But this will case the error “stopped unexpectedly”, as you descripted above.

change the order like this

    static {
        System.loadLibrary("cocos2d");
        System.loadLibrary("chipmunk");
        System.loadLibrary("helloworld");
    }

It works well. Note that helloworld depends on chipmunk, so you must load chipmunk before helloworld.

My solution is the attachment. You can run it, and compare to your source. I add some source invoking chipmunk in HelloWorldScene.cpp
Apologize for the late reply again, hope you can enjoy this engine

Walzer,

I’ll give that a try.

Thanks for your time and patience.

edited: That worked great! I’ll need to pay attention to loading order.

Hello,kanrinin_kanmasato(hirokazu_ono).
I ported cocos2d-x’s “chipmunk” & “BOX2D” to the Android Apps(applications) as to work.
Prease also see this url of git site below.

(I’m sorry that I also posted to “another BOX2D’s forum” just a little minutes ago. )
