Simply said
git clone https://github.com/Itzeez/opencv.git opencv
git clone https://github.com/Itseez/opencv_contrib.git opencv_contrib
cd opencv
mkdir build
cd build
cmake -D OPENCV_EXTRA_MODULES_PATH=../../opencv_contrib/modules ..
make -j $(nproc)
make install
Good luck
should i clone the git repositories inside the working directory(opencv) or in home?
If you clone and opencv folder does not exist then it will make one for you :) @Potato true, it depends on how many cores you have :D
Euhm did you run the make command in the same folder where you ran the cmake command? Then it should work!
yeah i did that but the error was in earlier code, there was error while executing "cmake -D OPENCV_EXTRA_MODULES_PATH=../../opencv_contrib/modules ..". the error is "CMake Error at 3rdparty/ippicv/downloader.cmake:75 (message): ICV: Failed to download ICV package: ippicv_linux_20141027.tgz. Status=22;"HTTP response code said error" Call Stack (most recent call first): 3rdparty/ippicv/downloader.cmake:108 (_icv_downloader) cmake/OpenCVFindIPP.cmake:235 (include) cmake/OpenCVFindLibsPerf.cmake:12 (include) CMakeLists.txt:526 (include)"
Ow that is because OpenCV has a partial IPP build available that it downloads each time you build OpenCV for a first run. Probably your system has no access to the internet to do so. Disable this package by adding -DWITH_IPP=OFF to your cmake command.
I executed the code cmake -DWITH_IPP=OFF but again i got some error, I am connected to the network. Can u clarify me how to disable the package?
