Hi George, 

This is a GUESS as I have not installed athena from macports. 

I can't be sure as I don't know if that version of Athena uses X11 but I imagine that it does. 

Try typing echo $DISPLAY in a terminal window and see if you get a result. If you don't then you may not have X11installed.

You can download X11 at http://xquartz.macosforge.org/trac

Hi Frank,

I installed Athena on OSX 10.8.5 using Macports. The error given below prints to the terminal when I run Athena, and Athena does not generate any plots. If there is any further information I can provide that would be helpful, let me know.

Graphics::GnuplotIF : cannot find environment variable DISPLAY

Best,

George

Hello Mac users,

I finally have launched a Mac OS X version of Demeter 0.9.18.2 on Macports. I have not tested it very much because I’m not actually a Demeter user. It builds, launches and opens some example data but beyond that, it is untested. If the Mac version interests you, fire up your Terminal and follow these instructions:

1. *Carefully* follow the steps to install Macports. <http://www.macports.org/install.php>

2. Open a new Terminal window and type the following. It will take a while depending on your computer and network speed. 

sudo port install demeter

3. When it is done, launch Athena by typing the following in Terminal. Note: Make sure you are in a directory you have write permission to (like your home directory) because it creates hidden log files at launch time. 

athena

It is a known issue that artemis and hephaestus do not launch right now, but Bruce is working on a fix that will be added soon. I'm not going to have time to debug people's Macports issues when installing Demeter with Macports, but tech support is available on the Macports Users mailing list [1]. You should not need any help installing if you correctly follow the intructions. Please let Bruce and I know if it works for you or not after you have it installed. I have only tested on OS X Mavericks and Mountain Lion so far. Keep in mind that this is the first working release candidate of Demeter on Mac OS X, so problems are going to be expected. 

Cheers!

Frank
