Spack provides some limited integration with environment module
systems to make it easier to use the packages it provides.
Installing Environment Modules
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
In order to use Spack's generated environment modules, you must have
installed the *Environment Modules* package. On many Linux
distributions, this can be installed from the vendor's repository.
For example: ```yum install environment-modules``
(Fedora/RHEL/CentOS). If your Linux distribution does not have
Environment Modules, you can get it with Spack:
1. Install with::
spack install environment-modules
2. Activate with::
MODULES_HOME=`spack location -i environment-modules`
MODULES_VERSION=`ls -1 $MODULES_HOME/Modules | head -1`
${MODULES_HOME}/Modules/${MODULES_VERSION}/bin/add.modules
This adds to your ``.bashrc`` (or similar) files, enabling Environment
Modules when you log in. It will ask your permission before changing
any files.
Spack and Environment Modules
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
You can enable shell support by sourcing some files in the
``/share/spack`` directory.
