Troubles in building the nrnpython for Neuron 7.1

[mattions]

Hello,

I'm trying to upgrade to the latest version of Neuron.
Compilation of Interview and Neuron works fine but I can't build the nrnpython.

It seems the setup.py coming with the package is somehow broken (or it's not well formed in my systems)

This is the error

Code: Select all

mattioni@pogo:nrnpython$ python setup.py install --prefix=~/local/
  File "setup.py", line 64
    = [ epre+libdirs[0],epre+libdirs[1] ],
    ^
SyntaxError: invalid syntax

and this is the part which cause trouble:

Code: Select all

hoc_module = Extension(
      "neuron.hoc",
      ["inithoc.cpp"],
      library_dirs=libdirs,
       = [ epre+libdirs[0],epre+libdirs[1] ],
      #extra_objects = [],
      libraries = [
	"nrnpython",
        "nrnoc", "oc", "nrniv", "ivoc",
        "memacs", "meschach", "neuron_gnu", "nrnmpi",
        "scopmath", "sparse13", "sundials", "IVhines",
	"readline"
      ],
      include_dirs = include_dirs,
      define_macros=defines
    )

Follows the whole file.

    print "Python presently executing setup.py: "+sys.executable
    print "These do not match, and the should!"

On a max os x that line is supposed to read
#extra_link_args = [ epre+libdirs[0],epre+libdirs[1] ],
and on all other machines it is supposed to read
extra_link_args = [ epre+libdirs[0],epre+libdirs[1] ],

I looked at the precursor file, setup.py.in which reads:
@setup_extra_link_args@ = [ epre+libdirs[0],epre+libdirs[1] ],
where configure decides what to put in place of the @...@ token.
In looking at nrn/m4/nrnpython.m4 I see that the only way this fails to
be set is if you configure with the '--with-nrnpython=dynamic' argument.
Is that how you are configuring?
Anyway, you can fix the setup.py file manually by putting in the correct
line above.

Hi!

Actually I figured out that I was not giving the --with-nrnpython option.
that fix my setup and the installation work properly.

I misread somewhere that the python interpreter was built by default. Anyway happy ending. thanks.
