make failed about darkmark HOT 16 CLOSED

You copied the message that says that make failed, but you failed to copy the error message that must have been printed before that. What is the actual error you are getting?

from darkmark.

My apologies...this is the error that occurred:
/home/skynet/DarkMark/src-launcher/VideoImportWindow.cpp: In constructor ‘dm::VideoImportWindow::VideoImportWindow(const string&, const VStr&)’:

Just guessing:
have you installed darkhelp and darknet prior to the installation of darkmark?

I have both darkhelp and darknet installed.

The error you report is from something that is part of OpenCV, not something in DarkMark. So you must not have installed OpenCV correctly, or you must be using a different operating system. Please share the exact installation steps you are using, including the version number, how it was installed, as well as the operating system including the version number.

from darkmark.

For C++: pkg-config --modversion opencv
3.2.0
For python: >>> cv2.version
'4.4.0'
I'm using Ubuntu 18.04.
I have DarkHelp installed, because I used it with my own application for yolo detection.
And I have Darknet installed (Alexey's latest Yolo V4)

Should I try to update my opencv-dev for the system?

from darkmark.

Something is not right. Did you build OpenCV by hand, or with the sudo apt-get install libopencv-dev command?

I booted up my old Ubuntu 18.04 VM and immediately ran into the same issues.

/home/stephane/src/DarkMark/src-launcher/VideoImportWindow.cpp:150:65: error: ‘CAP_PROP_CODEC_PIXEL_FORMAT’ is not a member of ‘cv::VideoCaptureProperties’
   const uint32_t format   = cap.get(cv::VideoCaptureProperties::CAP_PROP_CODEC_PIXEL_FORMAT );
                                                                 ^~~~~~~~~~~~~~~~~~~~~~~~~~~
/home/stephane/src/DarkMark/src-launcher/VideoImportWindow.cpp:172:25: error: ‘class cv::VideoCapture’ has no member named ‘getBackendName’
   ss << "Using " << cap.getBackendName() << " to read the video file \"" << shortname << "\"." << std::endl
                         ^~~~~~~~~~~~~~

So this is specific to the old version of OpenCV in Ubuntu 18.04 versus OpenCV in Ubuntu 20.04.

• Ubuntu 18.04 uses OpenCV v3.2.0
• Ubuntu 20.04 uses OpenCV v4.2.0

I will come up with a fix so DarkMark can be built cleanly on Ubuntu 18.04 and update this ticket once that is done.

from darkmark.

@robotwhispering Scott, please try the latest version and see if that fixes the problem. v1.4.10-1 is now building correctly for me on Ubuntu 18.04.

from darkmark.

No update in 2 months. Closing.

Sorry for bringing this up, but i have same issue. Tried to build DarkMark on Jetson nano, ubuntu 18.04. Darknet and DarkHelp works fine

from darkmark.

You are trying to build DarkMark on a Jetson nano?

from darkmark.

Yes, that's correct

from darkmark.

Pushed a change tonight to get DarkMark building with the old version of OpenCV installed on Jetson Nano devices. Please run git pull to get the latest changes and let me know if that fixed it.

from darkmark.

Works fine now, thanks
