Adding cpp files to cocos2d-x project android project

问题

I've followed this tutorial http://www.raywenderlich.com/33750/cocos2d-x-tutorial-for-ios-and-android-getting-started, and managed to create an android hello world project in cococs2d-x. Now when I add anything to my classes directory and try to use them, I get errors like

make: *** [obj/local/armeabi/libgame.so] Error 1
undefined reference to 'ConstAndStats::getDevice()' 

How should I fix these problems, and add the already working codes (in Xcode) for my eclipse project?

回答1:

This kind of error may appear if you add a class to the classes directory but forget to add it to the Android.mk file from the jni folder. Add something like this:

LOCAL_SRC_FILES := hellocpp/main.cpp \
          ../../Classes/YourClass.cpp \
          ../../Classes/YourLastClass.cpp
