Note: This version of the VDT (1.2.2) 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.

System requirements for VDT 1.2.2

Operating Systems

VDT 1.2.2 runs on RedHat 7.x, RedHat 9.0, RedHat Enterprise Linux 3 and Debian Linux 3.1 (sarge). It may work on other Linux releases but we do not guarantee it.

Disk space

VDT 1.2.2 takes different amounts of space depending on the operating system you use and the portions of the VDT you install on. On RedHat 9 a full VDT installation is about 500MB.

Pre-installed Software

• Pacman The VDT is installed with Pacman. For VDT 1.2.2 we recommend using Pacman 2.121. Note that for the installation to happen correctly on Debian you must use Pacman 2.121 -- not an earlier version. Until Pacman 3 is officially released we do not recommend using it.
• Python Pacman 2.121 requires Python 1.5.2 or later. This is usually installed on RedHat Linux computers so it should not be a problem for you. An easy way to check the version you have is to run python, then type control-D to exit

• gcc Although most of the VDT is installed as binaries the GNU C compiler (gcc) is required for a few portions of the installation. We recommend using the gcc that is distributed with your operating system. For RedHat 7.2 that is gcc 2.96. For RedHat 9.0 that is gcc 3.2.2.
• Perl The VDT requires a complete Perl installation which allows you to build and install new modules.
• tar Make sure that you are using the GNU tar version 1.13.12 or later.
• patch The VDT uses patch--any recent version is sufficient.
