Cmake installation failed / Ubuntu => Solved

[ihebski]

dlib/CMake installation failed for Ubuntu 14.04
Here is my solution :
Installing Boost, Boost.Python, and X11 can be accomplished easily with

$ sudo apt-get install build-essential cmake
$ sudo apt-get install libgtk-3-dev
$ sudo apt-get install libboost-all-dev

Installation of Cmake:
it tooks a while to install ~1.5 min

sudo wget  https://cmake.org/files/v3.9/cmake-3.9.0-rc5.tar.gz -O cmake.tar.gz
sudo tar -xvf cmake.tar.gz
cd cmake-3.9.0-rc5/
sudo chmod +x bootstrap
sudo ./bootstrap
sudo make && sudo make install

Dlib installation

$ wget https://bootstrap.pypa.io/get-pip.py
$ sudo python get-pip.py

Run all the examples using python3 ,it will works well now on Ubuntu 14.04
$ python3 find_facial_features_in_picture.py

I hope this will be helpful 👍 ,Happy H4cking .

Thanks for the tip!

Note to anyone else reading this: This only applies to the older Ubuntu 14.04. If you have Ubuntu 16.04 or newer, you don't need to do the extra steps and can just follow the README instructions.

get-pip.py: Permission denied seems you run it without permission ,try with sudo before running the command or change the current location into /tmp/ or /dev/shm or any writable directory .
