Question

我下载了面部检测的Dlib示例：http://dlib.net/face_detection_ex.cpp.html

并且只改变了三行，我的库在哪里：

在：

#include <dlib/image_processing/frontal_face_detector.h>
#include <dlib/gui_widgets.h>
#include <dlib/image_io.h>
#include <iostream>

using namespace dlib;
using namespace std;

后：

#include <~/dlib/image_processing/frontal_face_detector.h>
#include <~/dlib/gui_widgets.h>
#include <~/dlib/image_io.h>
#include <iostream>

using namespace dlib;
using namespace std;

但由于某种原因，g++无法找到它们：

$ g++ face_detection_ex.cpp -o face_detection_ex
face_detection_ex.cpp:40:59: fatal error: ~/dlib/image_processing/frontal_face_detector.h: No such file or directory
 #include <~/dlib/image_processing/frontal_face_detector.h>
                                                       ^
compilation terminated.

尽管所有库都在该文件夹中：

[me]@[me]-Dell-ProBook-6760g:~$ cat  ~/dlib/image_processing/frontal_face_detector.h

#include "../image_processing/object_detector.h"
#include "../image_processing/scan_fhog_pyramid.h"
#include <sstream>
#include "../compress_stream.h"
#include "../base64.h"

namespace dlib

为什么这不起作用？我在这里做错了什么？

g ++不检测文件是否存在，也不会链接它
