The spt3g installation instructions describe how to build the software, which creates a script that initializes a set of environment variables allowing you to import spt3g.
To avoid needing to run this script every time you want to use spt3g we
recommend using environment modules to setup the environment and loading the
modules in your .bashrc file.
In addition to needing the spt3g dependencies you also need to install the
environment-modules package, as well as the tcl package:
$ sudo apt-get update $ sudo apt-get install -y tcl environment-modules
To setup, copy this modules directory somewhere you would like to install it,
for the example we will use your home directory. You should then edit the first
uncommented line in modules/spt3g_shared to set the g3root to the
location you have cloned the spt3g_software to. For a user called "vagrant"
with spt3g_softare in their home directory it will look like this:
set g3root /home/vagrant/spt3g_software
Once you have updated this, add the following lines to your .bashrc file:
# load spt3g using environment modules module use --append /home/vagrant/modules module load spt3g_shared
Replace /vagrant/modules with the location you have copied this directory
to. You can then test by sourcing your .bashrc and trying to load spt3g:
$ source ~/.bashrc $ python3 -c "import spt3g.core"
This can be used to make a shared installation of spt3g, just have other
users add the same lines to their .bashrc file and make sure spt3g is
installed somewhere they have permissions to read it.
