How to install openBLAS (without apt-get)

Shows how to install openBLAS. I can install openBLAS with apt-get, but I installed it from the source code because the installation destination is not clear.

Let's go.

Download openBLAS source code

Normal download: http://www.openblas.net When using git: $git clone https://github.com/xianyi/OpenBLAS.git

Download to / home / Qiita / Download. (It was OpenBLAS-0.3.10.tar.gz in this article creation version)

Compile and install openBLAS

The installation destination is / opt / openblas.

compile&install

$sudo mkdir /opt/openblas
$cd /home/Qiita/Download
$tar -xvf  OpenBLAS-0.3.10.tar.gz
$cd /OpenBLAS-0.3.10
$make
$sudo make install PREFIX=/opt/openblas

It's done.
