Note: This web site is only kept up to date for OSG Software 1.2 (VDT 2.0.0). If you are looking for information for the most recent release, the RPM-based OSG Software 3.0, please see the OSG documentation web site

Note: This version of the VDT (1.3.2) is no longer supported. Feel free to look through the documentation and install it, but we cannot guarantee support for it. The current stable release is 2.0.0.

Installing Pacman

The VDT is distributed using Pacman. Pacman is a package manager like RPM or dpkg, but is much more powerful and designed to work on multiple platforms. Unfortunatly, Pacman does not come standard on any operating systems so you need to download and install it yourself.

1. Download Pacman This is version 2.126, which is the most recent version tested with VDT 1.3.2. Pacman 3.02 and beyond should also work without difficulty, but you'll need to use slightly different command-line arguments during the installation.
2. Unpack the tarball:

   > tar xvf pacman-2.126.tar.gz

3. Setup your environment to use pacman. This example assumes you're using the Bourne shell or Bash. If you're using the C shell you should source setup.csh instead.

   > cd pacman-2.126
   > source setup.sh

That's it! You can now move on and select the VDT packages you want to install.
