不能包括C ++头文件,如向量的Android NDK [英] Can't include C++ headers like vector in Android NDK
问题描述
当我尝试包括任何C ++类像载体在我的Android NDK的项目(使用NDK R5B,最新的),我得到如下所示的错误...
When I try to include any C++ class like vector in my Android NDK project (using NDK r5b, the latest), I get an error like the following...
++编译大拇指:测试libstl< =测试libstl.cpp
/Users/nitrex88/Desktop/Programming/EclipseProjects/STLTest/jni/test-libstl.cpp:3:18:错误:向量:没有这样的文件或目录
Compile++ thumb : test-libstl <= test-libstl.cpp

谁在线报道这个问题有人称成功加入其它人
Other people who reported this issue online have claimed success by adding
APP_STL:= stlport_static
他们Application.mk文件。我已经做到了这一点,以及审判APP_STL所有其他可能的值。我已经清理项目,跑NDK,打造干净,删除的OBJ文件和库文件夹,仍然当我编译它找不到vector类。我一直都在为这几个星期,现在(因为NDK R5出来了),希望如果有人有什么建议真的AP preciate。谢谢!
to their Application.mk file. I have done this as well as tried every other possible value for APP_STL. I've cleaned to project, ran ndk-build clean, deleted the obj and libs folders, and still when I compile it cannot find the vector class. I've been working on this for a number of weeks now (since NDK r5 came out) and would really appreciate if someone has any advice. Thanks!
推荐答案
这是可能的。下面是一些一步一步:
It is possible. Here is some step by step:
在 $ PROJECT_DIR / JNI / Application.mk
APP_STL := stlport_static
我试着用stlport_shared,但没有运气。同样的,的libstdc ++。
I tried using stlport_shared, but no luck. Same with libstdc++.
在 $ PROJECT_DIR / JNI / Android.mk
LOCAL_PATH := $(call my-dir)
include $(CLEAR_VARS)
LOCAL_MODULE := hello-jni
LOCAL_SRC_FILES := hello-jni.cpp
LOCAL_LDLIBS := -llog
include $(BUILD_SHARED_LIBRARY)
这里没有什么特别,但要确保你的文件的的.cpp
在 $ PROJECT_DIR / JNI / HELLO-jni.cpp
#include <string.h>
#include <jni.h>
#include <android/log.h>
#include <iostream>
#include <vector>
#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
// Comments omitted.
void
Java_com_example_hellojni_HelloJni_stringFromJNI( JNIEnv* env,
jobject thiz )
{
std::vector<std::string> vec;
// Go ahead and do some stuff with this vector of strings now.
}
#ifdef __cplusplus
}
#endif
唯一令咬在这里我是的#ifdef __cplusplus。
The only thing that bite me here was #ifdef __cplusplus.
