Based on IDL 8.5. New features are usually included here first for testing purposes. To help us iron out bugs and work towards the next stable release, your feedback will be very much appreciated. See installation instructions for basic help with installing DAVE using binaries or from source. If you experience a seg fault in Ubuntu (or any other) linux see Note 1 under linux installation instructions below.
Based on IDL 8.5 . This is essentially an incremental update of the software. In this release, the data reduction capability has seen the biggest impact with the addition of new modules and significant upgrades to existing ones. The changes reflect new instrumentation or upgrades in hardware. Please, consult the integrated User Manual for help on how to proceed. See, for example, the Description of DAVE Software chapter for an overview of application features and the Getting Started chapter for a beginner's tutorial.

Windows. Download the appropriate zip bundle. Unzip the downloaded file into a temporal directory. Navigate into the "dave" directory that is created, execute "Setup.exe" and follow the instructions to install DAVE. After installation an entry would be created in your start menu (as indicated during installation) from which you can launch DAVE. A destop shortcut is also created. Note that on some version of Windows, Administrator privileges are required to install an application.
You can just as easily uninstall DAVE (requires Administrator privileges) using one of two methods:
Note: X11 must be installed and running for DAVE to work. X11 for MacOS X can be obtained from the XQuartz project site.
Linux. download the appropriate version from the link above and extract the files (eg "tar zxvf downloaded_file.tgz"). Then change directory to the "dave" directory and run "./dave". Please note that DAVE must be launched from the installation directory otherwise some program modules may not work properly.
Note 1: For some linux distributions (eg Ubuntu 10.04), users have reported a seg fault with newer versions of DAVE which has been traced to a missing libstdC++ library. This can be fixed by locating and installing the package for your distribution that provides libstdC++.so.6. For Ubuntu, this can be achieved by visiting http://rpm.pbone.net/index.php3/stat/2/simple/2; enter libstdc++.so.6.0.3 in the search field and select RedHat EL 4 distro; then search, download and install the appropriate package that is found for your distribution.
Note 2: If you are experiencing any problems with fonts and/or plotting, then you need to modify the file called 'dave' and change the line:
so that the topdir variable points to the installation directory in which the 'dave' file is located. For example, if the downloaded DAVE archive was extracted into a directory called /home/path/to/dave, the line in the 'dave' file should be
This modification should also enable dave to be executed from anywhere (without changing directory to the installation directory first). Thus DAVE can be launched by issuing the command '/home/path/to/dave/dave' from anywhere.
In addition, executing the following soft link as root:
ln -s /home/path/to/dave/dave /usr/local/bin/dave
would give any user the ability to execute DAVE by simply typing dave on the command line irrespective of the current directory.
Note 1: A valid IDL license is required for this.
Note 2: The recommended IDL version is the one that we are currently using for our own builds (as indicated above for the stable and development versions).
Note 3: We can no longer support project files that work for IDL 6.4 or earlier!
Download the appropriate stable or development source code zip bundle and extract the contents into a self-contained directory. Proceed with the following steps to build and execute DAVE.
