[英]g++ openCV compile error on line that doesn't exist
我正在嘗試使用gcc test.cpp -o test
編譯並運行以下程序。 但我收到此錯誤:
In file included from test.cpp:4:
/usr/local/include/opencv/cvaux.hpp:49:10: error: 'cvaux.h' file not found with <angled>
include; use "quotes" instead
#include <cvaux.h>
^
1 error generated.
但是該行不在程序中。 我該怎么辦才能糾正這個問題?
程序:
// Example showing how to read and write images
#include <opencv2/opencv.hpp>
#include <opencv2/highgui/highgui.hpp>
#include <opencv/cvaux.hpp>
int main(int argc, char** argv)
{
IplImage * pInpImg = 0;
// Load an image from file - change this based on your image name
pInpImg = cvLoadImage("my_image.jpg", CV_LOAD_IMAGE_UNCHANGED);
if(!pInpImg)
{
fprintf(stderr, "failed to load input image\n");
return -1;
}
// Write the image to a file with a different name,
// using a different image format -- .png instead of .jpg
if( !cvSaveImage("my_image_copy.png", pInpImg) )
{
fprintf(stderr, "failed to write image file\n");
}
// Remember to free image memory after using it!
cvReleaseImage(&pInpImg);
return 0;
}
“我該怎么做才能糾正這一點?”
改用C ++ API:
// Example showing how to read and write images
#include <opencv2/opencv.hpp>
#include <opencv2/highgui/highgui.hpp>
using namespace cv;
int main(int argc, char** argv)
{
// Load an image from file - change this based on your image name
Mat img = imread("my_image.jpg", CV_LOAD_IMAGE_UNCHANGED);
if(img.empty())
{
fprintf(stderr, "failed to load input image\n");
return -1;
}
// this is just to show, that you won't have to pre-alloc
// result-images with c++ any more..
Mat gray;
cvtColor(img,gray,CV_BGR2GRAY);
// Write the image to a file with a different name,
// using a different image format -- .png instead of .jpg
if( ! imwrite("my_image_gray.png", gray) )
{
fprintf(stderr, "failed to write image file\n");
}
// no need to release anything with c++ !
return 0;
}
