【问题描述】：
因为我更习惯使用 Eclipse，所以我想尝试从 Visual Studio 转换我的项目。昨天我尝试了一个非常简单的小测试。无论我尝试什么，make 都会因“多个目标模式”而失败。 （这类似于this unanswered question。）
我有三个文件：
应用程序.cpp：
using namespace std;
#include "Window.h"
int main() {
Window *win = new Window();
delete &win;
return 0;
}
窗口.h：
#ifndef WINDOW_H_
#define WINDOW_H_
class Window {
public:
Window();
~Window();
};
#endif
Window.cpp：
#include <cv.h>
#include <highgui.h>
#include "Window.h"
const char* WINDOW_NAME = "MyApp";
Window::Window() {
cvNamedWindow(WINDOW_NAME, CV_WINDOW_AUTOSIZE);
cvResizeWindow(WINDOW_NAME, 200, 200);
cvMoveWindow(WINDOW_NAME, 0, 0);
int key = 0;
while (true) {
key = cvWaitKey(0);
if (key==27 || cvGetWindowHandle(WINDOW_NAME)==0) {
break;
}
}
}
Window::~Window() {
cvDestroyWindow(WINDOW_NAME);
}
我已将以下路径添加到编译器包含路径（-I）：
"$(OPENCV)/cv/include"
"$(OPENCV)/cxcore/include"
"$(OPENCV)/otherlibs/highgui"
我已将以下库添加到链接器 (-l)：
cv
cxcore
highgui
以及以下库搜索路径（-L）：
"$(OPENCV)/lib/"
Eclipse、编译器和链接器都成功地包含了头文件和库。我正在使用 Cygwin 的 GNU C/C++ 编译器和链接器。
编译时，我收到以下make 错误：
src/Window.d:1: *** multiple target patterns. Stop.
Window.d 包含：
src/Window.d src/Window.o: ../src/Window.cpp \
C:/Program\ Files/OpenCV/cv/include/cv.h \

C:/Program\ Files/OpenCV/cxcore/include/cxcore.h:
../src/Window.h:
我尝试从 Window.d 中删除所有 OpenCV 标头（从第 2 行开始），但错误仍然存在。另外，我更新了 Eclipse 和 OpenCV，都无济于事。
你有什么值得尝试的想法吗？我愿意尝试任何事情！
【问题讨论】：

您可能应该包含 makefile。由于这是来自
make的错误，这可能比实际的 C++ 源代码更重要。
