Android ndk-build iostream: No such file or directory

Question

I'm having problem with compiling cpp file using ndk-build tool (windows 7 with cygwin) Error appears when I try to compile cpp file with #include:

jni/native.cpp:5:20: error: iostream: No such file or directory 

Here is my cpp file:

#include <jni.h> #include <string.h> #include <stdio.h> #include <android/log.h> #include <iostream>  #define DEBUG_TAG "NDK_SampleActivity" #define  LOG_TAG    "hellojni" #define  LOGI(...)  __android_log_print(ANDROID_LOG_INFO,LOG_TAG,__VA_ARGS__) #define  LOGE(...)  __android_log_print(ANDROID_LOG_ERROR,LOG_TAG,__VA_ARGS__)   #ifdef __cplusplus extern "C" { #endif  void Java_com_test_ndk_SampleActivity_helloLog(JNIEnv* env, jobject thisobj, jstring logThis) {     jboolean isCopy;      const char * szLogThis = env->GetStringUTFChars(logThis, &isCopy);      __android_log_print(ANDROID_LOG_DEBUG, DEBUG_TAG, "NDK:LC: [%s]", szLogThis);      env->ReleaseStringUTFChars(logThis, szLogThis); }    #ifdef __cplusplus } #endif 

And here is my Android.mk file:

LOCAL_PATH := $(call my-dir)  include $(CLEAR_VARS)  APP_STL:=stlport_static   LOCAL_LDLIBS := -llog  LOCAL_MODULE    := swingbyte-android  LOCAL_SRC_FILES := native.cpp  LOCAL_C_INCLUDES := $(LOCAL_PATH)/include-all include $(BUILD_SHARED_LIBRARY) 

I have iostream file in android ndk folder (NDK_ROOT\sources\cxx-stl\gnu-libstdc++\include) but I don't have any idea how to tell compiler to look for iotream (and other standart header files) in that folder.

It seems to that I'm missing one or few environment variables, or some comiler flags.

I think "APP_STL:=stlport_static" must be in Application.mk file.

Create a "Application.mk" file and write "APP_STL:=stlport_static" in it.
