I'm wondering why the os-related file names that easy_install creates have macosx-10.3 in them (as opposed to 10.4), e.g.

creating /Library/Frameworks/Python.framework/Versions/2.4/lib/ python2.4/site-packages/numpy-1.0.1-py2.4-macosx-10.3-fat.egg

Is this something I should be concerned about?

No.

One of the reasons I was dorking around w/numpy again is because of a problem I ran into wrt scipy (this was when I was obtaining both from http://www.macpython.org/packages/py24-fat/index.html). Turns out that doing:

...

...

import scipy scipy.test()

...

...

from scipy import * RuntimeError: module compiled against version 1000002 of C-API but

produced: Python 2.4.4 (#1, Oct 18 2006, 10:34:39) [GCC 4.0.1 (Apple Computer, Inc. build 5341)] on darwin Type "help", "copyright", "credits" or "license" for more information. history mechanism set up this version of numpy is 1000009 Traceback (most recent call last): File "<stdin>", line 1, in ?

...

...

So I decided to try easy_install on both. Interestingly, the easy_install removed a sole (non-important) error when running numpy.test(), but I can't even get scipy to install into the site- packages directory; easy_install fails before it can do that (appended below). I am at my wits end.

Not sure if this helps but I stumbled upon the following trick. Do the following: 1) install g77 via instructions at: http://www.scipy.org/Installing_SciPy/Mac_OS_X. in particular download: http://prdownloads.sf.net/hpc/g77v3.4-bin.tar.gz?download and then do: sudo tar -xvf g77v3.4-bin.tar -C / which installs everything in /usr/local, most importantly creating: lrwxrwxrwx 1 root wheel 18 Dec 30 15:29 libg2c.0.dylib@ - libg2c.0.0.0.dylib lrwxrwxrwx 1 root wheel 18 Dec 30 15:29 libgcc_s.dylib@ -

libgcc_s.1.0.dylib

in /usr/local/lib/. 2) once this was done, magically scipy could work. in particular, these libg2c dylibs need to be on my machine. Not sure if this is equivalent to "getting the fortran stuff to work", but it at least allowed me to run all the spicy.test() On Dec 30, 2006, at 11:02 PM, Christopher Barker wrote:

Sorry, there isn't one at this point -- I think numpy, SciPy, MPL, and wx are all fairly stable right now, so it's a pretty good time to do it, but it's a challenge because:

1) SciPy, MPL, numpy and wx all have to be compatible -- so it's best if the same person does them all, or at least communicates enough to make sure the packages at pythonmac all match.

2) Building MPL requires the Universal version of a few libs (though libpng may be the only one now (or is it libjpeg? -- don't have my Mac handy), as there MAY be a version of libfreetype that works provided by Apple now.

This is the hardest one: 3) SciPy (or at least parts of it) requires Fortran. Apple has not released a gcc Fortran, and the ones that do exist are not Universal, and require libs in inconvenient places. This makes it hard to build a Universal, easy to install, binary of SciPy -- It's still hard to build one yourself, but if you don't need it universal, it is doable by mere mortals. I'd love to see a Universal one in the pythonmac repository

I think more on this point could really be helpful. I'm working off of Python2.4 because some AI-related code crashes on 2.5, so I hope this can still remain a priority. For me, the following combo seems to work good enough: 1) get matplotlib from www.macpython.org/packages/py24-fat (The superpack at scipy fails b/c a TkAgg library can't be found) 2) use the superpack for installing numpy and scipy. (These will only work for me if I've already done the g77 trick.) 3) use ipython gotten via easy_install (The superpack version is broken b/c it doesn't provide an executable)

(and I think with the right incantations of lipo , it should be doable), but in the meantime, maybe we should at least have separate PPC and Intel versions-- and is there any chance of either statically linking or putting the libs in the Python tree somewhere?

A need for a "scipy" package that actually works w/ipython, matplotlib, numpy, and scipy is seriously needed. Most of my friends think I'm crazy to have wasted all my time on this stuff. Its ridiculous.

So, I'd love to have someone:

Start with Python2.5 from pythonmac (2.4 would be nice too -- but let's focus on 2.5)

1) Get the latest wxPython for OS-X (2.8.*) 2) Build the latest numpy 3) Build MPL against the above (and Numeric and numarray, if possible) 4) Build SciPy for both Intel and PPC (probably separately) 5) Put all that up on pythonmac.

I'd like to do it, but I'm not the least bit sure when I'll be able to-- someone please beat me to it!

I would like to say I could help, but: i) I'm pretty new to all this, ii) I've wasted so much time getting something running on my machine that I'm running out of time (have a class I need to teach to prepare for). Hopefully my comments here are at least helpful :-) --b p.s. I'd like to thank you for all the work you've done on this regard. I'm beginning to realize how time consuming this open source stuff can be...

Hi All -

You can do this quite simply with fink if you have the patience to wait for the compilations to finish. This works on my ppc mac with XCode and fink installed (12/31/2006):

fink install scipy-py24 sudo apt-get install gettext-dev=0.10.40-25 gettext=0.10.40-25 fink install matplotlib-py24

For more details see this page I set up: http://howdy.physics.nyu.edu/index.php/Numpy_For_Mac_Using_Fink

Erin: Nice tutorial. I recommend one extra step though - right after installing fink, add 'unstable/main' to the 'Trees:' line in /sw/etc/fink.conf, and run 'fink selfupdate'. That way you will get the latest versions of all the packages. Also, if you want the python 2.5 versions, substitute 'py25' for 'py24'. -Jeff -- Jeffrey S.

I've generally stayed away form fink, as it felt like kind of a separate system within OS-X, rather than integrated -- kind of like cygwin. In particular, if you use Fink Python, can you: 1) Write apps that use the native GUI (not X), in particular, PyObjC, wx-Mac, and TK-aqua. 2) Bundle up apps with Py2App, or otherwise create self contained application bundles? 3) Universal (PPC+Intel) anything. Apart from "feel", I think those are the concrete reasons to use MacPython, rather than fink.

Hi Chris - I think you are correct. The solution I posted is not a long term solution for the eventual average numpy/scipy user. It was just a response to Belinda's original need for "Advice on a painless way to install scipy on my G5 OS X 10.4.8 mac". I don't mind waiting for things to compile so it seems painless to me. Erin
