OpenCV Eclipse configuration in linux

I want to configure eclipse-cdt for opencv in ubuntu. I followed the tutorial Using OpenCV with Eclipse (plugin CDT). However, I was ended up with error message

fatal error: cv.h: No such file or directory DisplayImage.cpp /opencvtest line 1 C/C++ Problem

I checked my configurations as indicated in the tutorial. Everything was fine except the information in 8.b.

As tutorial says for pkg-config --libs opencv, the output should be,

-L/usr/local/lib -lopencv_core -lopencv_imgproc -lopencv_highgui -lopencv_ml -lopencv_video -lopencv_features2d -lopencv_calib3d -lopencv_objdetect -lopencv_contrib -lopencv_legacy -lopencv_flann

But in my case the output was,

/usr/local/lib/libopencv_calib3d.so /usr/local/lib/libopencv_contrib.so /usr/local/lib/libopencv_core.so /usr/local/lib/libopencv_features2d.so /usr/local/lib/libopencv_flann.so /usr/local/lib/libopencv_gpu.so /usr/local/lib/libopencv_highgui.so /usr/local/lib/libopencv_imgproc.so /usr/local/lib/libopencv_legacy.so /usr/local/lib/libopencv_ml.so /usr/local/lib/libopencv_nonfree.so /usr/local/lib/libopencv_objdetect.so /usr/local/lib/libopencv_photo.so /usr/local/lib/libopencv_softcascade.so /usr/local/lib/libopencv_stitching.so /usr/local/lib/libopencv_ts.so /usr/local/lib/libopencv_video.so /usr/local/lib/libopencv_videostab.so

Can anyone help me to fix this problem.

Thank you in advance.

Your error message says that compiler can't find cv.h header. So your eclipse project's path configuration is not configured to see opencv headers. Please show output of pkg-config --cflags opencv. Make sure that your paths contain that folders. – Alexander Gorban
@Gorban pkg-config --cflags opencv o/p is "-I/usr/local/include/opencv -I/usr/local/include" – chatcja
Check that some of those paths contains cv.h. If it contains - configure "Path and Symbols" section of project's properties. – Alexander Gorban

Try to change your header from:

#include <cv.h>
#include <highgui.h>

to:

#include <opencv2/opencv.hpp>
#include <opencv2/highgui/highgui.hpp>

Thank you for all the answers. But the gain for the problem is bit strange. Here is it.

I am using ubuntu 12.1. I installed opencv using "git" as in the doc. Installation was completed without errors, but i received the above mentioned error.

Since any of the answers (@Alexander and @ Ann) didn't make any effect, I re-installed opencv using the downloaded file from "sourceforge". Then it worked perfectly. I think the problem was with the file I downloaded through git.

Anybody has any reason for this issue ?
