In this tutorial, Atomsk is supposed to be installed into the local directory of user, say ~/usr/local.
First, create a directory in which Atomsk is installed:
$ mkdir -p ~/local/src
and go to the source directory
$ cd ~/local/src
Then copy the source code by executing
$ git clone https://github.com/pierrehirel/atomsk/
Go to the source directory
$ cd atomsk/src
Edit makefile.ifort and add the following lines anywhere after "export"
INSTPATH=~ CONFPATH=~/.config
Then type
$ make -f Makefile.ifort atomsk
and
$ make -f Makefile.ifort install
Finally add the command search path in ~/.bashrc as
PATH=${PATH}:~/local/bin
and type
$ source ~/.bashrc
If you type
$ which atomsk
and get
~/local/bin/atomsk
you are all set!
