cd ~/GitHub/r-with-intel-mkl/
wget https://apt.repos.intel.com/intel-gpg-keys/GPG-PUB-KEY-INTEL-SW-PRODUCTS-2019.PUB
apt-key add GPG-PUB-KEY-INTEL-SW-PRODUCTS-2019.PUB

sudo sh -c 'echo deb https://apt.repos.intel.com/mkl all main > /etc/apt/sources.list.d/intel-mkl.list'
sudo apt-get update && sudo apt-get install intel-mkl-64bit

# Option 2: Use the installer (works well on Ubuntu 16.04)

cd ~/GitHub/r-with-intel-mkl/
wget http://registrationcenter-download.intel.com/akdlm/irc_nas/tec/12147/l_mkl_2017.4.239.tgz
tar xzvf l_mkl_2017.4.239.tgz
cd l_mkl_2017.4.239
sudo ./install_GUI.sh
printf '/opt/intel/lib/intel64\n/opt/intel/mkl/lib/intel64\n' | sudo tee -a /etc/ld.so.conf.d/intel_mkl.conf
sudo ldconfig

Care to comment about the intel_mkl.conf step? is it still current with mkl 2018?
Intel sure know how to produce loads of cyclic documentation hiding how this simple procedure should be carried out :-)

@matanster

You can add

export LD_LIBRARY_PATH=/opt/intel/lib/intel64:/opt/intel/mkl/lib/intel64:${LD_LIBRARY_PATH}

to your $HOME/.bashrc if you do not have write permission.

Lines 5-6 improved:

wget -O- https://apt.repos.intel.com/intel-gpg-keys/GPG-PUB-KEY-INTEL-SW-PRODUCTS-2019.PUB | apt-key add -

Don't pollute your filesystem

@v1993: You forgot sudo:

wget -O- https://apt.repos.intel.com/intel-gpg-keys/GPG-PUB-KEY-INTEL-SW-PRODUCTS-2019.PUB | sudo apt-key add -

so I'm having trouble setting up the MKL library on computer. I'm running gentoo linux and the system installs the files to /opt/intel/mkl/10.0.5.025. I don't see any directories mentioned as /opt/intel/lib/intel64 /opt/intel/mkl/lib/intel64. Am I using an incorrect version of MKL perhaps? Should I install MKL manually instead?

caution, install contains gui installs
