I'm installing Opencv3 on Centos 2.6 with Python 2.6. I get the error when I import cv. I get a Segmentation fault error.

I'm installing OpenCV like this:

yum update && \
yum install -y libjpeg-turbo && \
yum install -y libtiff-devel && \
yum install -y libpng-devel && \
yum install -y cmake python-devel numpy gcc gcc-c++ gtk2-devel libdc1394-devel libv41-devel ffmpeg-devel gstreamer-plugins-base-devel && \
yum groupinstall -y "Development Tools"

cmake -D CMAKE_BUILD_TYPE=RELEASE -D \
CMAKE_INSTALL_PREFIX=/usr/local -D \
OPENCV_EXTRA_MODULES_PATH=/opencv_contrib/modules/ .. 

make -j4 
make install 

/usr/local/lib/python2.6/site-packages/cv2.so /usr/lib/python2.6/site-packages/

Importing cv2 gives a segmentation fault error. I get the following output:

[root@localhost ~]# python
Python 2.6.6 (r266:84292, Jul 23 2015, 15:22:56)

it's probably a better idea, to build cv2.pyd statically:

cmake -D BUILD_SHARED_LIBS=OFF ......

I'm unaware what the difference is? can you please explain. if I use that flag, will it make the cv2.so that I then move to PYTHON PATH?

this way, cv2.so will be no more dependant on opencv so's at runtime

(but again, we don't know the reason for the crash, this is just a blunt guess)

well, what do you know...that worked. It created a cv2.so as well and after moving it to /usr/lib/python2.6/site-packages/ i was able to import cv2.
