Cocos2dx eclipse: Various "error: undefined reference to"
I am trying to port an iOS game to Android platform with cocos2dx 2.0.4. The core of the game is written in C ++, and we managed to run it on iOS, because the game is available in the Apple Store. I am using NDK r8d and the most recent SDK, but I run into a lot of problems when trying to build.
My application.mk looks like this:
APP_STL := stlport_shared APP_CPPFLAGS := -frtti NDK_TOOLCHAIN_VERSION=4.7
Android.mk:
LOCAL_PATH := $(call my-dir)
include $(CLEAR_VARS)
ifdef STLG
LOCAL_MODULE := stlport_stlg
else
LOCAL_MODULE := stlport
endif
LOCAL_CFLAGS += -D__ANDROID__ \
-isystem $(SYSROOT)/usr/include \
LOCAL_MODULE := game_shared
LOCAL_MODULE_FILENAME := libgame
LOCAL_CPPFLAGS += -fexceptions
LOCAL_C_INCLUDES := $(LOCAL_PATH)/../../Classes
LOCAL_C_INCLUDES := $(LOCAL_PATH)/../../Classes $(LOCAL_PATH)/../../../../Box2D $(LOCAL_PATH)/../../../../cocos2dx $(LOCAL_PATH)/../../../../
LOCAL_WHOLE_STATIC_LIBRARIES := cocos2dx_static cocosdenshion_static cocos_extension_static
include $(BUILD_SHARED_LIBRARY)
$(call import-module,CocosDenshion/android) \
$(call import-module,cocos2dx) \
$(call import-module,extensions)
Here's the console log (only errors are displayed):

Any help is greatly appreciated, thanks ...

You are getting the above undefined reference error because you have not added the required libraries to your Android.mk files. It looks something like this.
LOCAL_LDLIBS: = -L $ (call host path, $ (LOCAL_PATH) /../../ libs / $ (TARGET_ARCH_ABI)) \ -lcocos2d -lGLESv1_CM -llog -lgame_logic
I got stuck with this issue even after adding libraries. Its something to do with setting the path, but I don't know how ..
If you solve it let me know
