非常简单的应用程序失败，“多目标模式”从Eclipse [英] Very simple application fails with "multiple target patterns" from Eclipse
问题描述
使失败与多目标模式。 （这类似于这个未回答的问题）。 我有三个文件：
Application.cpp：
code> using namespace std;
#includeWindow.h
int main（）{
Window * win = new Window（）;
delete& win;
return 0;
}
Window.h：
#ifndef WINDOW_H_
#define WINDOW_H_
class Window {
public：
Window（）;
〜Window（）;
};
#endif
Window.cpp：
#include< cv.h>
#include< highgui.h>
#includeWindow.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）;
}
我已经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 </ code>）：
code> cv
cxcore
highgui
以下图书馆搜索路径（ -L ）：
$（OPENCV）/ lib /
Eclipse，编译器和链接器都成功地包含了标题和库。我正在使用GNU C / C ++编译器链接器从Cygwin。
编译时，我得到以下 make 错误：
src / Window.d：1：***多个目标模式。停止。
Window.d包含：

我尝试从Window.d（从第2行开始）删除所有OpenCV标头，但是错误仍然存在。此外，我已经更新了Eclipse和OpenCV，都无济于事。
你有什么想法值得吗？我愿意尝试任何东西！
您是从Cygwin安装工作吗？
我在使用Cygwin之前看到这个问题 - 基本上， make 看到 ：在路径中，认为它是另一个目标定义，因此出现错误。
如果您是从Cygwin安装工作，您可以尝试将 c：/ 替换为 / cygdrive / c / 。如果没有，您可以尝试使用相对路径或使用网络挂载，并查看是否修复它。
Since I'm more comfortable using Eclipse, I thought I'd try converting my project from Visual Studio. Yesterday I tried a very simple little test. No matter what I try, make fails with "multiple target patterns". (This is similar to this unanswered question.)
I have three files:
Application.cpp:
using namespace std;
#include "Window.h"
int main() {
Window *win = new Window();
delete &win;
return 0;
}
Window.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);
}
I have added the following paths to the compiler include path (-I):
"$(OPENCV)/cv/include"
"$(OPENCV)/cxcore/include"
"$(OPENCV)/otherlibs/highgui"
I have added the following libraries to the linker (-l):
cv
cxcore
highgui
And the following library search path (-L):
"$(OPENCV)/lib/"
Eclipse, the compiler and the linker all succeed in including the headers and libraries. I am using the GNU C/C++ compiler & linker from Cygwin.
When compiling, I get the following make error:
src/Window.d:1: *** multiple target patterns. Stop.
Window.d contains:
src/Window.d src/Window.o: ../src/Window.cpp \

C:/Program\ Files/OpenCV/cxcore/include/cxcore.h:
../src/Window.h:
I tried removing all OpenCV headers from Window.d (from line 2 onwards), but the error remains. Also, I've updated Eclipse and OpenCV, all to no avail.
Do you have any ideas worth trying? I'm willing to try anything!
Are you working from a Cygwin installation?
I've seen this problem before using Cygwin--basically, make sees the : in the path and thinks it is another target definition, hence the error.
If you are working from a Cygwin installation, you might try replacing the c:/ with /cygdrive/c/. If not, you might try using relative paths or using a network mount and see if that fixes it.
