I guess I've changed make all -j4 to make all -($(nproc)) after running the script and forgot to look for typos. My bad.

Changed to make all -j$(nproc) as @johntian pointed out.

How do I solve this problem?

for anybody else getting CUDA-related errors when running the cmake command, you can add another flag to skip the CUDA stuff (and then install it later on, which is what I did):

-D WITH_CUDA=OFF

I've met the following errors and failed to find the solution:

Does anyone know the reason why "recipe for target 'XXX' failed" happens all the time?

Not sure how, but does anyone know how to add more recent GPU architectures for it to build so the annoying nvcc warning stops appearing? I know you can even specify like "Kepler" or "Fermi" (not sure about Maxwell). Either that or add -D WITH_CUDA=OFF like @wkentdag said.

As to me , it works.

Notes for Ubuntu 17.10.

  • libgstreamer is upgraded to v1.0 so it's not possible to install v0.10 via apt.
    Unable to locate package libgstreamer0.10-dev
  • And also every command related to libgstreamer is broken since the version is changed.
  • libjasper-dev is removed from the repository. I couldn't find the replacement at the moment.
    Unable to locate package libjasper-dev
  • libpng is upgraded to v16. So you should use "libpng-dev" instead. This should install all development headers and the current version from the repository.

Hello,

I get a strange error during the cmake process itself (running on Ubuntu16.04). It says -

/home/aashishsharma/Desktop/opencv-2.4.13.5/release/CMakeFiles/CMakeTmp/CheckSymbolExists.cxx:8:19: error: ‘Q_WS_WIN’ was not declared in this scope
return ((int*)(&Q_WS_WIN))[argc];

Can anybody please help me out? I can share the entire log if needed. Thanks!

Instructions works well on ubuntu 18 as well just by using the newest set of packages available for the distro

thank you very much

you can try with chmod +x install_opencv2_ubuntu.sh before you run the shell script.

@drsagitn 'sudo apt-get install python-opencv
pip install opencv-python' installs opencv 3.3.0. What is the way to install opencv 2.4.13?
Thanks in advance.

Hi,
were you able to install python binding via apt-get install python-opencv for the above OpenCV installation?

Thanks, but in my case script not worked as intended at first time... since... I had no unzip :)

For someone like me, it seems good to add script doing sudo apt install -y unzip

Also good to have set -e at the first line to stop procedure for the case like me
