2011-02-16 16:25:19 +0200	marked best answer	Running octave from the sage notebook Have you let Sage know where Octave is? That is, is Octave in your `PATH`? What I mean is whether you can just type `octave` to launch octave, or if you have to do something like `/path/to/octave/octave_executable` (the latter might not be visible to Sage). Otherwise I'm out of ideas, too.
2011-02-16 16:25:04 +0200	answered a question	Running octave from the sage notebook As per kcrisman's answer above, I added a softlink from /opt/local/bin/octave to /usr/bin/octave, and now the sage server works. Similarly adding a link to /usr/local/bin/octave did not work.

2011-02-16 16:21:50 +0200	commented answer	Running octave from the sage notebook I believe so. My .bashrc file extends the path to include /opt/local/bin/, which is where MacPorts installs octave. However, I don't know whether sage can find octave. Maybe I'll try to make a soft link to /usr/local/bin/ or /usr/bin/ or something.

2011-02-16 14:40:16 +0200	asked a question	Running octave from the sage notebook I'm trying to run octave through the sage notebook. When I try to evaluate a cell (e.g. x = linspace(0,1,100)), I get the error message: RuntimeError: Unable to start octave Examining the traceback in more detail doesn't point to anything that suggests how to fix the problem, and I was wondering whether anyone else had this problem. Octave is installed on my computer, and runs fine from the command line. Can anyone help me with this? Thanks in advance!
