IllegalArgumentException: Unable to find native library: cocos2dcpp

cocos2d-x C++
#1

HI,

my first post :slight_smile:

  1. Path Variable COCOS2DX:
    * Eclipse->Preferences->General->Workspace->Linked Resources
    I have set to /home/q/Downloads/cocos2d-x-3.0rc0

  2. C/C++ Environment Variable NDK_ROOT:
    I have set to /home/q/Downloads/android-ndk-r9b

  3. Environment Variables:
    PATH="/usr/lib/lightdm/lightdm:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games:/home/q/Downloads/android-sdk-linux/tools:/home/q/Downloads/android-sdk-linux/platform-tools"
    JAVA_HOME=/usr/lib/jvm/jdk1.7.0_51
    COCOS2DX_ROOT=/home/q/Downloads/cocos2d-x-3.0rc0
    NDK_ROOT=/home/q/Downloads/android-ndk-r9b
    ANDROID_HOME=/home/q/Downloads/android-sdk-linux
    ANDROID_SDK_ROOT=/home/q/Downloads/android-sdk-linux
    SDK_ROOT=/home/q/Downloads/android-sdk-linux

  4. Import libcocos2dx library project:
    form
    /home/q/Downloads/cocos2d-x-3.0rc0/cocos/2d/platform/android/java/

5.Import template
/home/q/Downloads/cocos2d-x-3.0rc0/templates/cpp-template-default/proj.android/

6.Try to start HelloCpp template => not working see log

7.because inside the HelloCpp template Project the Classes folder and the cocos2dx folder
cannot be resolved(the folder structure has changed since the alpha version)
Classes:
Location:COCOS2DX/projects/HelloCpp/Classes
Resolved location:/home/q/Downloads/cocos2d-x-3.0rc0/projects/HelloCpp/Classes - (does not exist)
cocos2dx:
Location:COCOS2DX/cocos2dx
Resolved location:/home/q/Downloads/cocos2d-x-3.0rc0/cocos2dx - (does not exist)

8.So In the HelloCpp template project I changed the locations the Classes folder and the cocos2dx folder
Classes:
Location:COCOS2DX/templates/cpp-template-default/Classes
Resolved location:/home/q/Downloads/cocos2d-x-3.0rc0/templates/cpp-template-default/Classes
cocos2dx:
Location:COCOS2DX/cocos
Resolved location:/home/q/Downloads/cocos2d-x-3.0rc0/cocos

9. No change. Still getting the same error. See log

Cocos version 2 and version 3 alpha have worked for me.
But version 3 beta and RC don’t.
I need you help.

HERE IS THE LOG:

v3rc0 on eclipse!
#2

did you compile source code by build_native.py?

#3

:slight_smile: I forget to do it. But it’s missing some stuff:

Is my NDK_MODULE_PATH correct ??
NDK_MODULE_PATH=${COCOS2DX_ROOT}:${COCOS2DX_ROOT}/cocos/2d/platform/android:${COCOS2DX_ROOT}/cocos/2d

#4

I tried

NDK_MODULE_PATH=${COCOS2DX_ROOT}

but build_native.py still not working.

I changed the line 135 (inside build_native.py)
FROM: cocos_root = os.path.join(current_dir, “…/cocos2d”)
TO: cocos_root = os.path.join("", “/home/q/Downloads/cocos2d-x-3.0rc0”)

now it build’s(the .so) correct.

But i can’t start it on phone (galaxy s2). Get the ERROR

#5

On Windows 8, Visual Studio 2013, it runs perfect

just opened cocos2d-x-3.0rc0\build\cocos2d-win32.vc2012.sln

but i need to run it on a andriod phone(eclipse,ubuntu13.10)
