Neuron 7.2 Python error

[ssaluga]

I usually have no problem installing Neuron in our lab, but with 10.7.4, I am getting the following error:

-e

I do have the Enthought Python additions installed.
Any ideas on how to fix, I would prefer not to have to mess around with command line changes if necessary.
Thank you all in advance,

Suggest that you install the latest 7.3 alpha instead, specifically
http://www.neuron.yale.edu/ftp/neuron/v ... 10.7.4.dmg

You'll also need the latest version of the command line developer tools, in order to be able to compile mod files. Go to
http://developer.apple.com/opensource
and click on the "Download command line developer tools . . . " link. You'll have to sign in with your Apple ID and password.

If you are interested in using parallel hardware to handle large models or speed up your simulations, you will want to install OpenMPI. Download this file
http://www.open-mpi.org/software/ompi/v ... 1.6.tar.gz
then

Code: Select all

tar xzf openmpi-1.6.tar.gz
cd openmpi-1.6
./configure
make
make install

In case anyone else runs into this problem:
I ran into this same error and I am pretty sure I got 7.2 running only by installing the developer tools.
