Question

我正在尝试将OpenCV与Netbeans 7.3.1一起使用。我尝试过各种教程和博客，但无法运行任何文件。以下代码被列为检查opencv安装的好示例代码：

#include <cstdlib>

using namespace std;
#include "opencv.hpp"
#include "opencv_modules.hpp"
int main ( int argc, char **argv ) { 
    cvNamedWindow( "My Window", 1 ); 
    IplImage *img = cvCreateImage( cvSize( 640, 480 ), IPL_DEPTH_8U, 1 ); 
    CvFont font; 
    double hScale = 1.0; 
    double vScale = 1.0; 
    int lineWidth = 1; 
    cvInitFont( &font, CV_FONT_HERSHEY_SIMPLEX | CV_FONT_ITALIC, hScale, vScale, 0, lineWidth ); 
    cvPutText( img, "Hello World!, I can now code openCV ", cvPoint( 0, 200 ), &font, Scalar    
    (255, 255, 0 ) ); 
    cvPutText( img, "in a kickass IDE ", cvPoint( 150, 300 ), &font, cvScalar( 255, 255, 0 ) ); 
    cvShowImage( "My Window", img ); 
    cvWaitKey(); 
return 0; 
}

代码导致以下错误： “/ usr / bin / make”-f nbproject / Makefile-Debug.mk QMAKE = SUBPROJECTS = .build-conf make [1]：输入目录/cygdrive/c/Users/Daniel/Documents/NetBeansProjects/CppApplication_4' "/usr/bin/make" -f nbproject/Makefile-Debug.mk dist/Debug/Cygwin_1-Windows/cppapplication_4.exe make[2]: Entering directory / cygdrive / c / Users / Daniel / Documents / NetBeansProjects / CppApplication_4' mkdir -p build / Debug / Cygwin_1-Windows rm -f build / Debug / Cygwin_1-Windows / main.o.d g ++ -c -g -I ../../../../../ Program \ Files / OpenCV / build / include / opencv2 -MMD -MP -MF build / Debug / Cygwin_1-Windows / main.od -o build / Debug / Cygwin_1-Windows / main.o main.cpp 在main.cpp：11中包含的文件中： ../../../../../Program Files / OpenCV / build / include / opencv2 / opencv.hpp:46：33：opencv2 / core / core_c.h：没有这样的文件或目录 ../../../../../Program Files / OpenCV / build / include / opencv2 / opencv.hpp:47:33:opencv2/core/core.hpp：没有这样的文件或目录 ../../../../../Program Files / OpenCV / build / include / opencv2 / opencv.hpp:48：39：opencv2 / flann / miniflann.hpp：没有这样的文件或目录 ../../../../../Program Files / OpenCV / build / include / opencv2 / opencv.hpp:49:39:opencv2/imgproc/imgproc_c.h：没有这样的文件或目录 ../../../../../Program Files / OpenCV / build / include / opencv2 / opencv.hpp:50:39:opencv2/imgproc/imgproc.hpp：没有这样的文件或目录 ../../../../../Program Files / OpenCV / build / include / opencv2 / opencv.hpp:51:35:opencv2 / photo / photo.hpp：没有这样的文件或目录 ../../../../../Program Files / OpenCV / build / include / opencv2 / opencv.hpp:52：35：opencv2 / video / video.hpp：没有这样的文件或目录 ../../../../../Program Files / OpenCV / build / include / opencv2 / opencv.hpp:53:45:opencv2/ features2d / features2d.hpp：没有这样的文件或目录 ../../../../../Program Files / OpenCV / build / include / opencv2 / opencv.hpp:54:43:opencv2/objdetect/objdetect.hpp：没有这样的文件或目录 ../../../../../Program Files / OpenCV / build / include / opencv2 / opencv.hpp:55：39：opencv2 / calib3d / calib3d.hpp：没有这样的文件或目录 ../../../../../Program Files / OpenCV / build / include / opencv2 / opencv.hpp:56:29:opencv2/ml/ml.hpp：没有这样的文件或目录 ../../../../../Program Files / OpenCV / build / include / opencv2 / opencv.hpp:57:39：opencv2 / highgui / highgui_c.h：没有这样的文件或目录 ../../../../../Program Files / OpenCV / build / include / opencv2 / opencv.hpp:58：39：opencv2 / highgui / highgui.hpp：没有这样的文件或目录 ../../../../../Program Files / OpenCV / build / include / opencv2 / opencv.hpp:59:39:opencv2/ contrib / contrib.hpp：没有这样的文件或目录 main.cpp：在函数int main(int, char**)': main.cpp:14: error:中cvNamedWindow'未声明（首先使用此函数） main.cpp：14：错误:(每个未声明的标识符仅针对它出现的每个函数报告一次。） main.cpp：15：错误：IplImage' undeclared (first use this function) main.cpp:15: error: img'未声明（首先使用此函数） main.cpp：15：错误：cvSize' undeclared (first use this function) main.cpp:15: error: IPL_DEPTH_8U'未声明（首先使用此函数） main.cpp：15：错误：cvCreateImage' undeclared (first use this function) main.cpp:16: error: CvFont'未声明（首先使用此函数） main.cpp：16：错误：期望;' before "font" main.cpp:17: error:字体'未声明（首先使用此函数） main.cpp：17：错误：CV_FONT_HERSHEY_SIMPLEX' undeclared (first use this function) main.cpp:17: error: CV_FONT_ITALIC'未声明（首次使用此功能） main.cpp：17：错误：cvInitFont' undeclared (first use this function) main.cpp:18: error: cvPoint'未声明（首先使用此函数） main.cpp：18：错误：cvScalar' undeclared (first use this function) main.cpp:18: error: cvPutText'未声明（首先使用此函数） main.cpp：20：错误：cvShowImage' undeclared (first use this function) main.cpp:21: error: cvWaitKey'未声明（首先使用此函数） nbproject / Makefile-Debug.mk：86：目标build/Debug/Cygwin_1-Windows/main.o' failed make[2]: *** [build/Debug/Cygwin_1-Windows/main.o] Error 1 make[2]: Leaving directory / cygdrive / c / Users / Daniel / Documents / NetBeansProjects / CppApplication_4的配方' nbproject / Makefile-Debug.mk：59：目标.build-conf' failed make[1]: *** [.build-conf] Error 2 make[1]: Leaving directory / cygdrive / c / Users / Daniel / Documents / NetBeansProjects / CppApplication_4'的配方 nbproject / Makefile-impl.mk：39：目标`.build-impl'的配方失败 make： * [.build-impl]错误2

BUILD FAILED（退出值2，总时间：2s）

任何人都可以提供一套明确的指示或者至少指向一份简明的指南吗？

谢谢，丹尼尔

Answer 1

假设您的包含路径包含C:\Program Files\OpenCV\include，并且包含文件确实位于那里，请替换

#include "opencv.hpp"

与

#include "opencv2/opencv.hpp"

你可能没有#include "opencv_modules.hpp"，否则它应该是#include "opencv2/opencv_modules.hpp"

将OpenCV与netbeans 7.3.1连接起来
