Opencv error on ARM - c++

Question

I hope someone can help me. I have a c++ file which use opencv libraries.
I need to get an executable for an ARM in which I have to run it. My executable should be compile in a static linker way.
I am not an exepert so sorry If I am doing something weird, I follow this steps:
I download the opencv for ARM libraries, I build it with the cmake and I got the statics opencv ARM libraries without problems.
Then I try to compile my c++ file like this:
arm-linux-g++ -static -o exampleWindows IPCamera.cpp `pkg-config --cflags --libs opencv`
And it works, so I got an executable, I write:
file executable
And I get this output:
ELF 32-bit LSB executable, ARM, version 1 (SYSV), statically linked, for GNU/Linux 2.6.26, not stripped
So it seems that is ok, is an ARM format and is a static linked. But when I try to run this executable in my ARM is comming this error:
OpenCV Error: Unspecified error (The function is not implemented.
Rebuild the library with Windows, GTK+ 2.x or Carbon support.
If you are on Ubuntu or Debian, install libgtk2.0-dev and pkg-config,
then re-run cmake or configure script) in cvNamedWindow,
file /home/jesus/opencv/opencv/modules/highgui/src/window.cpp, line 483
terminate called after throwing an instance of 'cv::Exception'
what(): /home/jesus/opencv/opencv/modules/highgui/src/window.cpp:483: error: (-2) The function is not implemented.
Rebuild the library with Windows, GTK+ 2.x or Carbon support. If you are on Ubuntu or Debian, install libgtk2.0-dev and pkg-config,
then re-run cmake or configure script in function cvNamedWindow
Then how I am not an expert I tried to follow what the error message says, so I donwload the libgtk2.0 in my ubuntu, and then I make again the cmake and make for build the ARM static libraries, but nothing is solved.
So I need some help with this error, or tell what is the meaning, because it seem that is simple but I do not know what to do.
Here is my code:
#include <iostream>
#include <pthread.h>
#include <opencv2/opencv.hpp>
#include <opencv2/imgproc/imgproc.hpp>
#include <opencv/highgui.h>
#include <string.h>
#include <stdio.h>
#include <time.h>
using namespace std;
using namespace cv;
int main()
{
cout<<"ready"<<endl;
cv::Mat frame;
cv::namedWindow("front", CV_WINDOW_NORMAL);
cvMoveWindow("front", 0, 0);
cvSetWindowProperty( "front", CV_WND_PROP_FULLSCREEN, CV_WINDOW_FULLSCREEN);
return 0;
}
Thank you so much I hope someon could help me.

Answer 1

The problem is that you need to rebuild OpenCV with the GTK-support activated. The necessary steps are:
Install gtk (sudo apt-get install libgtk2.0-dev, I think you did this already ;) ).
Rebuild OpenCV:
If you installed it from the repositories, re-install it (I think this is not the case).
If you manually built OpenCV from source code: run cmake with it again, making sure that the option WITH_GTK is marked (you can use the CMAKE GUI to activate that option).
Once the Makefiles have been re-generated with CMAKE, run make, make install and don't forget ldconfig.
Try again with your code ;)
Hope that it helps!

Answer 2

The problem is due to the fact that, you did not enable the GTK+ library support .
To enable it
1)install the GTK+ Libraries, if you don't have them
2) re build the libraries with including this -DWITH_GTK=ON
hope that this will work...

Answer 3

run ccmake . and enable WITH_GTK and WITH_GTK_2_X
run make && make install
ldconfig
