[Numpy-discussion] installing numpy on Tiger

[Alan I. <ai...@am...>]

If other users will not profit from this question,
please consider it OT and ignore it.  But perhaps
it will prove useful to some potential numpy users.

I am a long time Windows user who has been happily
using the Python and numpy installers.  At work I
need to use a Mac for a while.  I installed Python 2.5
from python.org painlessly, but it looks like
I'll have to compile numpy from source.
Do I understand that right?

I have used interpreted languages for pretty much
all my computing needs, so I am hoping someone patient
will point me to or lead me through the steps I need
to take to successfully install numpy on this platform.

Thank you,
Alan Isaac

This is probably a good starting point:

http://www.scipy.org/Installing_SciPy/Mac_OS_X

There have been numerous threads on this issue recently, so you may
also want to do a bit of searching of the mailing list archives.

I believe you'll have to if you want to use Python 2.5.

I think the instructions on the scipy wiki are pretty thorough:
http://scipy.org/Installing_SciPy/Mac_OS_X

One thing to note is that I think I've seen on this list that people  
have been having problems compiling and using num/scipy on Python 2.5  
(on any platform (?)) ... I haven't tried it myself, but that's the  
general feeling I've gotten from some of the emails on that subject.  
I could be wrong though.

Another thing to consider would be to install the "Superpack" which  
is linked to in the mac section from the scipy downloads page:
http://www.scipy.org/Download

I also remember seeing on the ML that there were some problems w/  
that superpack it not including some config file for ipython or  
something, but I'm not sure.

For what it's worth, I'm using MacPorts (http://macports.org) to  
manage my python (and a other) installations, and have been compiling  
scipy/numpy/matplotlib/ipython from svn checkouts every now and  
again ... this has been working well for me. The version of python  
you get from macports is 2.4.3

Hope that helps.

Hi Alan -

I have not had luck with the binary distros.  There is always
something that doesn't work, so I will be interested in
the results of your efforts.

The biggest problem with compiling things yourself is going
to be dealing with LAPACK and fortran issues, and the
backends in matplotlib.

FWIW, the most stable solution I have found that doesn't involve
dealing with dependencies yourself is darwinports (now
macports).  It currently has 1.0b5 numpy and scipy 0.5.1, which
depend on python 2.4. Matplotlib worked with the wxPython
backend but not others.  While not the latest versions it will get
you started, and I would guess 1.0 will be available soon (anyone?).
I had absolutely zero problems using this once I realized that I
had to use wxPython for the plotting backend.  The snag
is that gfortran is needed, which requires compiling gcc 4.0 which
took 6 hours on my powerbook, so you will need some patience.

Nice binaries for gfortran can be found here:

Do you know how to make macports recognize this compiler if
it is outside the macports tree? I had a version of gfortran (4.2.0)
already on my system, but it insisted on compiling its own version
(4.1.1)
