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.
