opencv 3.0 build error (possible resolution: QT gui issues)

[amiltonwong]

Hi, Paul,

As the OpenDTAM is towards the target opencv 3.0, I plan to shifted into new opencv 3.0 environment. But I came across the build error as follows:

[ 42%] Building CXX object modules/calib3d/CMakeFiles/opencv_calib3d.dir/src/stereosgbm.cpp.o [ 42%] Building CXX object modules/calib3d/CMakeFiles/opencv_calib3d.dir/src/dls.cpp.o /root/Downloads/opencv-3.0/modules/calib3d/src/dls.cpp:11:31: fatal error: Eigen/Eigenvalues: No such file or directory compilation terminated. make[2]: * [modules/calib3d/CMakeFiles/opencv_calib3d.dir/src/dls.cpp.o] Error 1 make[1]: * [modules/calib3d/CMakeFiles/opencv_calib3d.dir/all] Error 2 make: *\ [all] Error 2

Before, the output from cmake-gui is as follows:

It seems very strange that the system cannot find "Eigen/Eigenvalues" while the cmake-gui could recognize EIGEN in "/usr/include/eigen2". Could you give me some suggestions on how to fix it?

Best regards, Milton

Ah. You should actually use my opencv fork for building the 3.0 version because it has the pull request already incorporated. I have given up trying to compile the trunk directly anyway, the build sytem is far too convoluted for me to debug.

[amiltonwong]

Thanks Paul. The building step of opencv 3.0 succeeded after using your opencv fork. Then I downloaded the most recent version of OpenDTAM and built it successfully. But when I run it by "./a.out", something failed after the initialization of first 500 frames. It shows as follows:

text_file_name = ../../Trajectory_30_seconds/scene_498.txt Opening: ../../Trajectory_30_seconds/scene_498.png text_file_name = ../../Trajectory_30_seconds/scene_499.txt Opening: ../../Trajectory_30_seconds/scene_499.png Paused: Space (in GUI window) to continue

(A function:2822): GLib-GObject-CRITICAL **: g_object_unref: assertion `G_IS_OBJECT (object)' failed

(A function:2822): GLib-GObject-CRITICAL **: g_object_unref: assertion `G_IS_OBJECT (object)' failed

All the windows (Actual Image, Control, D function, A function, Predicted Image, etc..) had popped out but only in black screen. And I found that my GPU was running. Could you suggest me how to fix it?

Best regards, Milton

Sorry, I've been out for a while. I have seen this error before, but forget what was wrong. I think it may have been that QT wasn't actually working. Try calling displayOverlay to see if it is working. You could also try calling imwrite after imshow from inside the graphics.cpp file to see if the expected image is getting to the graphics routines

[ernest-galbrun]

@amiltonwong: I had the same issue, and I could not exactly solve it. However, removing the line 119 in graphics.cpp did the trick for me: namedWindow("control",WINDOW_NORMAL);

I also have a weird bug, with waitKey(0) always returning 1 but that's another problem and easy to go around...

[anuranbaka]

Yep, almost certainly a problem with the new QT interface then. The "WINDOW_NORMAL" attribute converts a window to one without the nice QT viewer features.

I don't know if this will help you guys, but I just solved this error in my own code. I had a window open with a few track bars without any image being shown inside the window. I continually got the above error because of that control window. Then I added an image to the window and the error went away. I think this error is simply because my control window was not given a picture or video. I was googling that specific error and came across this bug. I hope this helps you out.
