# Pmodules
|
|
|
|
Pmodules are a hierarchical module environment based on [Environment Modules](http://modules.sourceforge.net).
|
|
For the time being they are still using the C implementation of the Environment Modules.
|
|
|
|
*Future plans*
|
|
* Version 2 will be a re-implementation in Tcl using the modulecmd of Environment Modules.
|
|
* Version 3 will be implementat as extension of Environment Modules.
|
|
|
|
## Install a new Pmodules environment
|
|
|
|
All Pmodules and all required software is installed in a directory hierarchy
|
|
in one unique root directory. If required or prefered dedicated directories can
|
|
be defined for temporary files and/or downloaded files.
|
|
|
|
In the most cases a Pmodules environment will be installed on a network file-system,
|
|
but local disk is of course also possible. Just make sure you have write access to
|
|
to Pmodules root directory. The Pmodules root directory defaults to `/opt/psi`.
|
|
|
|
*Installation*
|
|
1. clone this repository and cd into it.
|
|
2. create the Pmodules root directory and make sure you have write access with
|
|
the user you want to use to setup the new Pmodules environment. In the following
|
|
steps we use `$PMODULES_ROOT` as symbols for the root directory.
|
|
3. Run
|
|
```
|
|
./build configure --prefix=$PMODULES_ROOT
|
|
```
|
|
to configure a new Pmodules environment. This command creates the configuration
|
|
file `$PMODULES_ROOT/config/modbuild.conf` and some directories under `$PMODULES_ROOT`
|
|
required in the next steps.
|
|
4. Run
|
|
```
|
|
./build compile --prefix=$PMODULES_ROOT
|
|
```
|
|
to compile and install the required tools.
|
|
5. Run
|
|
```
|
|
./build install --prefix=$PMODULES_ROOT
|
|
```
|
|
to install the Pmodules scripts.
|
|
|
|
If you don't want to use `$PMODULES_ROOT/var/tmp/${USER}` for temporary files
|
|
you can override the default by using the option `--tmpdir=TEMP_DIR` in step 3.
|
|
|
|
If you don't want to use `$PMODULES_ROOT/var/distfiles` for downloaded files
|
|
you can override the default by using the option `--distfilesdir=DISTDIR` in step 3.
