NEURON with Python 3.1 installation

[kadir]

I am trying to install NEURON as a Python 3.1 module.

First, I tried to do it with Python 2.6. I followed the instruction at http://www.davison.webfactional.com/not ... on-python/ and the installation was successful.

Then, I changed the "python link" to python3 and got:

Code: Select all

$ ls -al python
lrwxrwxrwx 1 root root 7 2011-02-18 17:27 python -> python3

I removed NEURON and tried to reinstall for Python 3. When I entered

Code: Select all

$ sudo ./configure --prefix=/opt/nrn-7.1 --with-iv=/opt/iv-17 --with-nrnpython

it gave me the following error:

Code: Select all

Python binary found (/usr/bin/python)
checking nrnpython configuration...   File "<string>", line 2
    print distutils.sysconfig.get_python_version()
                  ^
SyntaxError: invalid syntax
get_python_version()  '' returning '2.4'
  File "<string>", line 2
    print distutils.sysconfig.get_python_inc(1)
                  ^
SyntaxError: invalid syntax
get_python_inc(1)  '' returning ''
configure: error: cannot determine python include directory. Need to
explicitly specify PYINCDIR

Does anyone know how to cope with this or another way to install NEURON as a Python 3.1 module?

Thanks in advance

Suggest you try this with NEURON v. 7.2, either from a recent alpha package or the latest development code from the mercurial repository.

i suppose there's a problem with generating "ansi.lo", but i'm not sure.

start with a fresh directory and try 'make' instead of 'sudo make'. If that succeeds then you can do
the next step 'sudo make install'.

By the way, the current version of NEURON for Python 3.1 has a memory leak for strings passed from Python to NEURON.
I have not yet been able to figure out a way to avoid it.
