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"

OPENCV_EXTRA_MODULES_PATH=/opencv_contrib/modules/ .. 

make -j4 
make install 

/usr/local/lib/python2.6/site-packages/ /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:

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

this way, 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 as well and after moving it to /usr/lib/python2.6/site-packages/ i was able to import cv2.
