If you are facing any errors while building OpenCV, first do this. Go to terminal and enter:

sudo yum update --skip-broken

To ensure that the OpenCV gets built properly, it is necessary to configure Python as follows during installation:

./configure --enable-share
make
make test
make install

Also, 'cmake' may not be installed - you can get it by entering this in terminal:

sudo yum install cmake

To prevent errors during installation, do the following in terminal:

sudo yum update --skip-broken

Then, reconfigure Python as follows:

./configure --enable-share
make
make test
make install

Then, install 'cmake':

sudo yum install cmake

Finally, install OpenCV according to the instructions in this article.
