Undefined references appears when including iostream - android

I have tried to compile very simple code for android:
#include <iostream>
void foo()
{
}
But I get some linking errors:
/home/l/android-ndk-r7b/sources/cxx-stl/gnu-libstdc++/include/iostream:72: undefined reference to `std::ios_base::Init::Init()'
/home/l/eclipse_workspace/android_bt_test1/jni/native.cpp:33: undefined reference to `std::ios_base::Init::~Init()'
My Application.mk is:
APP_OPTIM := debug
APP_MODULES := native_lab
APP_STL := gnustl_static
My Android.mk is:
LOCAL_PATH:= $(call my-dir)
include $(CLEAR_VARS)
LOCAL_MODULE := native_lab
LOCAL_C_INCLUDES := $(LOCAL_PATH)
LOCAL_SRC_FILES := native.cpp
LOCAL_LDLIBS := -ldl -lstdc++ -llog
LOCAL_C_INCLUDES := $(LOCAL_PATH)/include /home/l/android-ndk-r7b/sources/cxx-stl/gnu-libstdc++/include/ /home/l/android-ndk-r7b/sources/cxx-stl/gnu-libstdc++/libs/armeabi/include
include $(BUILD_SHARED_LIBRARY)
I know this problem is very easy, but I have't found a resolution.
Could anybody help me please?

AddressSanitizier: error: undefined reference to "__asan_report_load4"

When I compiled a test Android program by enabling the AddressSanitizier, I got this error:
error: undefined reference to __asan_report_load4
Does anyone know what happened here?
This is my Android.mk：

undefined reference error while building FFMPEG with NDK

I get this error while running build-ndk for my ffmpeg android project
make: *** [obj/local/armeabi-v7a/libffmpeg-test-jni.so]

Any solutions to get rid of this error ? I am very new to ffmpeg and Android NDK
This is my Android MK file

Any Pointers much appreciated

Android studio NDK Undefined reference to GL functions

I made small JNI-based project.
I do #include GLES3/gl3.h in my C code and it works. But when I try to use ANY OpenGL function it says Undefined reference to gl*. My Android.mk is:
LOCAL_PATH := $(call my-dir)
include $(CLEAR_VARS)
LOCAL_MODULE := hello-jni
LOCAL_CFLAGS := -Wall -Wextra
LOCAL_SRC_FILES := hello-jni.c
LOCAL_LDLIBS := -lGLESv3 -ldl -llog
LOCAL_STATIC_LIBRARIES := android_native_app_glue
include $(BUILD_SHARED_LIBRARY)
What I am doing wrong? Could some one tell me what's wrong?

Try linking to EGL as well.
For my projects, I use these libraries:
LOCAL_LDLIBS := -llog -landroid -lEGL -lGLESv3

Android NDK, two Static Libraries and Linking

I started off creating libraries as shared libraries, but I considered it would be more efficient to create one shared libraries and the rest static. When it was all shared, it compiled and linked fine, but moving to static, I get on linking "undefined reference".
Edit: I build all the libraries in one Android.mk
Android.mk:
MY_LOCAL_PATH := $(call my-dir)
MY_LOCAL_CFLAGS := -DDEBUG
TARGET_PLATFORM := 'android-4'
LOCAL_PATH := $(MY_LOCAL_PATH)/../../Base
include $(CLEAR_VARS)
LOCAL_MODULE := Base
LOCAL_SRC_FILES := <Base src files>
include $(BUILD_STATIC_LIBRARY)
MY_LOCAL_STATIC_LIBRARIES := Base
MY_LOCAL_C_INCLUDES := $(MY_LOCAL_PATH)/../../Base
LOCAL_PATH := $(MY_LOCAL_PATH)/../../Framework
include $(CLEAR_VARS)
LOCAL_MODULE := Framework
LOCAL_C_INCLUDES := $(MY_LOCAL_C_INCLUDES)
LOCAL_SRC_FILES := <Framework src files>
LOCAL_CFLAGS := $(MY_LOCAL_CFLAGS)
include $(BUILD_STATIC_LIBRARY)
MY_LOCAL_STATIC_LIBRARIES += Framework
MY_LOCAL_C_INCLUDES += $(MY_LOCAL_PATH)/../../Framework
LOCAL_PATH := $(MY_LOCAL_PATH)/Graphics
include $(CLEAR_VARS)
LOCAL_MODULE := Graphics
LOCAL_SRC_FILES := <Graphics src files>
LOCAL_EXPORT_LDLIBS := -lGLESv1_CM
LOCAL_CFLAGS := $(MY_LOCAL_CFLAGS)
LOCAL_C_INCLUDES := $(MY_LOCAL_C_INCLUDES)
include $(BUILD_STATIC_LIBRARY)
MY_LOCAL_STATIC_LIBRARIES += Graphics
MY_LOCAL_C_INCLUDES += $(MY_LOCAL_PATH)/Graphics
LOCAL_PATH := $(MY_LOCAL_PATH)/Platform
include $(CLEAR_VARS)
LOCAL_MODULE := Platform
LOCAL_SRC_FILES := <Platform src files>
LOCAL_CFLAGS := $(MY_LOCAL_CFLAGS)
LOCAL_C_INCLUDES := $(MY_LOCAL_C_INCLUDES)
include $(BUILD_STATIC_LIBRARY)
MY_LOCAL_STATIC_LIBRARIES += Platform
MY_LOCAL_C_INCLUDES += $(MY_LOCAL_PATH)/Platform
LOCAL_PATH := $(MY_LOCAL_PATH)
include $(CLEAR_VARS)
LOCAL_MODULE := Final
LOCAL_SRC_FILES := <Final src files>
LOCAL_STATIC_LIBRARIES := $(MY_LOCAL_STATIC_LIBRARIES)
LOCAL_LDLIBS := -llog
LOCAL_CFLAGS := $(MY_LOCAL_CFLAGS)
LOCAL_C_INCLUDES := $(MY_LOCAL_C_INCLUDES)

/Users/robbie/Documents/Apps/Revolution/Android/jni/SpinTap/ATexture.cpp:9: undefined reference to `TextureRenderer::TextureRenderer(unsigned int)'
Edit2: TextureRenderer is in Graphics, which is included.
Does anyone have an idea why it may not be working and how to fix it?

This looks like an order-of-linking issue to me.
Your command line is:
arm-linux-androideabi-g++ -Wl,-soname,libFinal.so -shared \
libBase.a libFramework.a libGraphics.a libPlatform.a -o libFinal.so
and the error is
libPlatform.a(ATexture.o): In function `ATexture':
ATexture.cpp:9: undefined reference to `TextureRenderer'
ATexture.cpp:9: undefined reference to `TextureRenderer'
TextureRenderer is in Graphics. But libGraphics is before libPlatform on the command line. g++ will search each library on the command line in the order they are given, loading functions to resolve external references. It will read libGraphics once, load the functions that resolve external references and move on to libPlatform.
Try changing LOCAL_STATIC_LIBRARIES := $(MY_LOCAL_STATIC_LIBRARIES) to LOCAL_STATIC_LIBRARIES := Platform Graphics Framework Base and see how you get on.

In your Android.mk, make sure you are referencing the static library with the proper call:
LOCAL_STATIC_LIBRARIES := mystaticlibproj
before calling include $(BUILD_SHARED_LIBRARY).
Then, at the end of the file, place the call to import the static lib module
$(call import-module, mystaticlibproj)
If you're still having trouble, post the verbose build log (ndk-build V=1 -B) and your Android.mk
