CentOS Question posted in
The official documentation can be found here.

Why am I not able to install dlib library on my centos?

I’m having trouble installing dlib on a centos7 server that doesn’t have a GPU.
I’ve looked through the internet but was unable to find a valid solution.
One of the answers which I came across was that The problem was that Python needs to be compiled with the --enable-shared flag for the dlib install to succeed.
But apparently this should be avoided because it can cause additional problems.

This is the error I get.
