Downloading Duchamp

Obtaining Duchamp code

Version 1.6.1 of Duchamp is now available [1 May 2014]. It can be downloaded in source format, in a gzipped tar archive. The code will need to be compiled on your local machine: a configure script and a Makefile are provided to make this as easy as possible.

This release contains a patch for a particular memory leak issue that was present in 1.5 and 1.6. In the process, some changes have been made to a few function interfaces, although this will be transparent to all save for code developers using the library. The progress bar now also prints a percentage as well as the series of hashes. For further details of these changes, consult the CHANGES file.

Three external libraries are required (in addition to the standard C/C++ libraries): PGPLOT, CFITSIO and WCSLIB. It is possible to compile Duchamp without having PGPLOT on your system: you just won't get any of the nice useful graphical output. See the README file for complete information on installation of Duchamp.

Feedback and bug reporting

I'm always keen to hear from people who have used Duchamp, especially if they have comments on the way it works or suggestions as to how it can be improved. I may not have been thinking of your particular application when I wrote it, so if it doesn't do something you think it should, let me know!

There is a mailing list duchamp-user<at>atnf.csiro.au that users of Duchamp can subscribe to. This will be used to announce updates to the code and any other general issues. All messages will be archived here.

Note that you need to be subscribed to send and receive messages from this list:

To subscribe, please send a message to duchamp-user-request<at>atnf.csiro.au with the single word "subscribe" in the body of the message. Send this from your normal email account.
If you wish to be removed from this list send an email to duchamp-user-request<at>atnf.csiro.au with the single word "unsubscribe" in the body of the message.

If you wish to report a bug or a problem, or make a suggestion for new and/or improved features, then go to the Duchamp Trac wiki site. There you can submit a new ticket (computer-speak for a bug report or feature request). You can also view any previous reports -- perhaps your problem has already been reported.
