Not able to build openCV from source

1

Error occurs when building files using make command.

System information (version)
  • OpenCV => 4.5.1
  • Operating System / Platform => Virtual Machine Ubuntu 20.04.2 LTS
  • cmake --version=> 3.16.3
  • make --version=> GNU Make 4.2.1
Additional Information

  • Guide followed =>OpenCV: Install OpenCV-Python in Ubuntu
    //Also installed Optional depencies

  • Since by default cmake builds opencv for Python2 i wrote this command to build opencv for python3=>
    cmake {...} -DPYTHON_DEFAULT_EXECUTABLE=$(which python3) ../

I removed some output due to word limit, full output on openCV building from source [Failed] - Pastebin.com

Hi,
I don’t know what is the problem in compilation. Something is missing in your log file. Can you show us all gapi module build?
But you can disable gapi module -DBUILD_opencv_gapi:BOOL=OFF
or disable perf_test -DBUILD_PERF_TESTS:BOOL=OFF

Thank you for the quick reply.
Do you want me to run this command=>

@crackwitz i did not abort manually. I have tried building multiple times and every time it fails at 93%. I am currently building with this command

cmake -DBUILD_opencv_gapi:BOOL=OFF \
> -DPYTHON_DEFAULT_EXECUTABLE=$(which python3) ../

since make takes a lot of time, i will update you when its done

9

BUILD_opencv_gapi:BOOL=OFF should be bypassing any issues stemming from the module so I hope building with that option will succeed.

if it doesn’t, try running with make -j1 (or maybe some other appropriate value). some people on the internet say the error can happen because the system is out of resources (too many parallel builds)

got error again. i will try different command later @crackwitz @laurent.berger

Full output is on Building from source (BUILD_opencv_gapi:BOOL=OFF) - Pastebin.com

I do not why opencv is using python2 for building. I tried using these cmake configurations(in hope that opencv will only use python3) but got the same error as last time at 100%=>

What’s your platform?

  • Operating System / Platform => Virtual Machine Ubuntu 20.04.2 LTS (64-bit)

I am running Ubuntu in a virtual machine on Windows 10.

  • Virtual Machine info. => Oracle VM Virtual Box 6.1
16

how much RAM did you allocate to that VM?

it’s failing right at the end, maybe in a linking step, which might mean you’re running out of RAM.

the mysterious KILL signal might mean linux’s OOM killer acted on the process.

you can build and use OpenCV on Windows. you don’t need to satisfy all the optional dependencies either. a missing optional dependency might cause just a single module to be unavailable.

@crackwitz It worked. I finally build opencv from source. I removed the opencv clone and then downloaded a new clone. I also increased RAM. (so i don’t know what worked). Thank you for helping

[SOLVED]

Things i did.

  • Followed this guide OpenCV: Install OpenCV-Python in Ubuntu

  • Options i gave in cmake

    • In cmake, i turned off build for opencv_gapi
      (since make command was failing at building opencv_gapi)
    • I wanted to build opencv for python3 , so in cmake command i gave this option (check python3 full path with this command which python3)
    • cmake command

    cmake -DBUILD_opencv_gapi:BOOL=OFF -DPYTHON_DEFAULT_EXECUTABLE=/usr/bin/python3 ../

  • Delete opencv clone and download new clone whenever possible(I think this was one of the reason why make command was failing at same percentage, even after giving different options. But I don’t know for sure).

  • Try increasing RAM and disk size
