Hi Chris, I tried your suggestion of installing and running the pre-built packages at <http://www.pythonmac.org/packages/py24-fat/>. I am sorry to report that the pre-built MacPython and Numeric 24.2 package did not work. I get the same "Segmentation Fault" that I got when I built Python 2.4.3 and Numeric 24.2 from source.
I tried running my code with debug prints in various places to try and pin down where the problem arises. Thus, I ran my code a number of times. Strangely, it never crashes in the same place twice. I'm not sure what to do next, but I will keep at it. As a last resort, I may build ATLAS and LAPACK from source, then build Numeric 23.8 against these, and try installing this into MacPython. I hate having to try this, but I cannot do any development without a functioning Python and Numeric. Thanks again, Daran -- > Daran L. Rife wrote: >> Many thanks for the reply.

It has some nice additional features that Numeric does not have, but is missing some as well.

It is based on the Numeric code base, and is designed to have the best features of Numeric and numarray, plus some extra good stuff. It is now at version 1.0beta, with an expected release date for 1.0final sometime this fall. It is under active development, the API is pretty stable now, and it appears to have the consensus of the numerical python community as the "way of the future" > > I wrote all that out so that you can be clear which package you are having trouble with -- you've used both the term "Numeric" and "numpy" in your posts, and there is some confusion. > > If you are working on a project that does not need to be released for a few months (i.e. after numpy has reached 1.0 final), I'd use numpy, rather than Numeric or numarray. > > Also: on OS-X, there are far to many ways to build Python. When you report a problem, you need to define exactly which python build you are using, and this goes beyond python version -- fink? darwinports? built-it-from-source? Framework?

They should be built against Apple's vectLib. There isn't a package for numpy 1.0beta there yet.

You can compare the setup.py files from that and newer versions to see how to make it build against vectLib, but I suspect if you do that, you'll see the same problems. > > Also, please send a small test script that crashes for you, so others can test it. > > -Chris > > > > > -- > Christopher Barker, Ph.D. > Oceanographer > > NOAA/OR&R/HAZMAT (206) 526-6959 voice > 7600 Sand Point Way NE (206) 526-6329 fax > Seattle, WA 98115 (206) 526-6317 main reception > > [EMAIL PROTECTED] > ------------------------------------------------------------------------- Using Tomcat but need to do more?
