Error running the apk: Android + Box2D + Eclipse + cocos2d-x 2.2.2

cocos2d-x C++
#1

Hi all,

I’m trying to get cocos2d-x working with Box2D.

I get the following error:
02-25 23:05:45.957: E/cocos2d-x assert(16344): CCApplication.cpp function:sharedApplication line:60
02-25 23:05:45.967: A/libc(16344): Fatal signal 11 (SIGSEGV) at 0x00000000 (code=1), thread 16500 (Thread-1744)

I have added the following code into HelloWorldScene.cpp:

b2CircleShape circle;
circle.m_radius = 26.0/PTM_RATIO;

Any help would be nice, since I can’t seem to find a proper answer on how to add Box2D properly to 2.2.2 cocos-2dx. Some articles contain older cocos2dx version, which seem not relevant anymore.

Regards,
Morrowyn

Have you checked the TestCpp samples? There is a Box2D test.

#3

Just tested it. I have exact the same error. I have imported cocos2dx/platform/java as eclipse project, rebuilt everything and when debugging, I get the same crash.

#4

@morrowyn Try to copy the java src files into the project. You could refer to http://www.cocos2d-x.org/forums/6/topics/36265 for more information.

Thanks for the help. I fixed the problem. I had to add cocos2dx android project to the Android Build Path. However when the phonescreen is off and I try to run it i get the following (ndk-stack):

Btw, to get Box2D working, you need to disable Chipmunk: Application.mk

APP_STL := gnustl_static
APP_CPPFLAGS := -frtti -DCC_ENABLE_CHIPMUNK_INTEGRATION=0 -DCOCOS2D_DEBUG=1 -DCC_ENABLE_BOX2D_INTEGRATION=1
