do reboot

 

 

 

2. Download all sources, change configuration

 

download and unzip the sources

mkdir opencv_install
cd opencv_install
wget -O opencv.zip https://github.com/opencv/opencv/archive/3.4.1.zip
wget -O opencv_contrib.zip https://github.com/opencv/opencv_contrib/archive/3.4.1.zip
unzip opencv.zip
unzip opencv_contrib.zip

 

before building you have to modify a file related to cuda

sudo vim /usr/local/cuda/include/cuda_gl_interop.h

and go to line 61, and modify like below

//#if defined(__arm__) || defined(__aarch64__)
//#ifndef GL_VERSION
//#error Please include the appropriate gl headers before including cuda_gl_interop.h
//#endif
//#else
#include <GL/gl.h>
//#endif

comment all lines except #include <GL/gl.h>

 

Set environment variables

export PATH="/usr/local/cuda-10.2/bin:$PATH"
export LD_LIBRARY_PATH="/usr/local/cuda-10.2/lib64:$LD_LIBRARY_PATH"

 

 

3. build opencv

cd opencv-3.4.1
mkdir build && cd build

make -j4

rm -rf /usr/include/opencv4/opencv2
sudo make install
