Where the OpenCV headers on Jetson TK1?

Autonomous Machines Jetson & Embedded Systems Jetson TK1
#1

Hello!
I confused…
I installed and configured all for developing with Nsight Eclipse, by this tutorial:
http://www.hnwatcher.com/r/1110185/Setting-up-Jetson-TK1-for-OpenCV-Development
and try to build simple example:

#include "opencv2\highgui\highgui.hpp"
#include "opencv2\imgproc\imgproc.hpp"

int main() {
	setenv("DISPLAY", ":0", 0);
	cv::Mat image;
	image = cv::imread("lenna.jpg");
	cv::namedWindow("Original Image");
	cv::imshow("Original Image", image);
}

and got error:

fatal error: opencv2\highgui\highgui.hpp: No such file or directory

Where I may find the opencv headers?

Thanks!

It depends, did you build cmake yourself? If you did, the headers are probably in /usr/local/include.

#3

I installed it from pre-built libraries.

#4

Have you looked at /usr/include?

#5

So that’s where it!:) Ok, how I must add it to my project?

#6

when compiling it would be -I/usr/include/. You may have errors if you use #include “opencv2\highgui\highgui.hpp” . Try #include <opencv2\highgui\highgui.hpp>

#7

It doesn’t work. How I can include headers from Jetson? Because, I don’t have this headers on the host machine.

#8

How are you compiling your code, are you using nsight to cross compile?

#9

No. I use nsight to remote development.

#10

Have you tried ssh to the board and using g++ -I/usr/include -L/usr/lib -lopencv_imgproc -lopencv_highgui -o (program) just to get it complied?

#11

Maybe through Nsight you would have to go through settings, then nvcc compiler and in the include section you would add the directory where the opencv headers are placed.

#12

I get the same error

I have already done this, but there’s no any effect

#13

Looking at the code, I see that the includes have \ can you try changing them to /, Linux uses / and Windows uses .

#14

It looks like a magic… I deleted my project from host machine, than made “git clone” again. Than I created new project with the same code, and everything works!

Thanks for your answers!
