I have problem with running build_native.sh in android cocos2d-x project. it turns out to be some linking problem. the cpp files that I created are not compiled and so become undefined reference.
here’s the error :
SoybeanServer-2:android soybeansoft$ ./build_native.sh

some people say that I need to list all the cpp files i created in Android.mk file in the Classes folder. But after I look out at the Classes folder, there’s no Android.mk there.
so how should I list the .cpp files now?
Update :
I know that there’s android.mk file in jni folder. but even if I list all my game cpp file there , the cpp still not compiled in the build_native process. So I really have no idea how to list my cpp files.
android.mk file will be in the jni folder of the eclipse project. Look over there.
