Apps cnnot build a simple app

[mariusc]

Hi,
I am trying to build a simple C++ app and insert it in android package.
Here are the steps I did:

1. made a new folder in android/external/myapp
2. this folder has one cpp file myapp.cpp having following code:

 class Hello
{
  public: 
   Hello(){printf("hello");}
   ~Hello(){}
}  ;

int main(argv, argc[])
{
    Hello* h = new Hello();
    delete h;
}

and Android mk

LOCAL_PATH := $(call my-dir)
include $(CLEAR_VARS)
LOCAL_SRC_FILES :=   myapp.cpp    
LOCAL_C_INCLUDES := 
LOCAL_SHARED_LIBRARIES :=  libstdc++ #libutils -libcutils
                                
LOCAL_LDLIBS += $(EXTRA_LDLIBS)
LOCAL_MODULE := myapp
include $(BUILD_EXECUTABLE)

Then I add my app to main.mk @ /android/build.code/main.nk right after the

external/zlib \
external/myapp \   # < - here

When I build i get unresolved externals

undefined reference to `__cxa_end_cleanup' in function '~Hello'
(.ARM.extab.text._ZN11HelloAtMyAppcpp+0x0): undefined reference to `__gxx_personality_v0'

Thank you.

Why do you use C++
What is your destination ?

I manage to get it linked.
Destination was

/system/bin/mydaemon


Thank you.
