Hi, So I had no problem installing yt on my ubuntu box. I'm running 8.10, with recent updates applied, and it's a 32-bit pentium 4 machine from around mid-2004. I'm running gfortran:
[20:52][/opt/yt]$ gfortran --version GNU Fortran (Ubuntu 4.3.2-1ubuntu11) 4.3.2 Copyright (C) 2008 Free Software Foundation, Inc.
GNU Fortran comes with NO WARRANTY, to the extent permitted by law. You may redistribute copies of GNU Fortran under the terms of the GNU General Public License. For more information about these matters, see the file named COPYING << version 4.3.2. Can you tell me which version of gfortran (not g77, which we're trying to avoid using :) you are running? This will be an important datapoint for any future notes I write up about this. I've uploaded my entire (minus source except for yt source) distribution here: http://yt.enzotools.org/files/yt-ubuntu-32bit.zip Unfortunately, it's got some hardcoded paths, so you will at least have to make it *think* that it's in: /opt/yt/ ... so you could either symlink /opt/yt/yt-unknown/ to wherever you unzip it, or you could just unzip it in /opt/yt/ . As for the interactive interpreter, "iyt" is just a front end to ipython. Running "ipython -pylab" and doing the command "from yt.mods import *" will get you the same thing as "iyt". Additionally, running the standard python interpreter puts you into an interactive environment as well, and you can import yt as per usual. I talk about this a little bit in the documentation: http://yt.enzotools.org/doc/quick_guide/index.html All of the commands inside ipython are commands that will work in the standard python interpreter if you run "from yt.mods import *" . Let me know how this goes, Matt
