---------- Forwarded message ---------- From: Martin Rubey <[EMAIL PROTECTED]> Date: Tue, Oct 28, 2008 at 8:34 PM Subject: [SAGEdev] calling python from lisp To: Cc: sage-devel <[EMAIL PROTECTED]> The following message is a courtesy copy of an article that has been posted to comp.lang.lisp,comp.lang.python as well. Dear all, I'm trying to call from common lisp functions written for Sage (www.sagemath.org), which in turn is written in python. To do so, I tried http://common-lisp.net/project/python-on-lisp/. It was quite easy to get it to run and do some simple things with python. However, I was unable to get sage to run within it. If I start my local python 2.5 and follow (roughly) http://www.sagemath.org/doc/tut/node55.html it works nicely: [EMAIL PROTECTED]:~/Documents/sage-3.1.4/local/bin$ . ./sage-env [EMAIL PROTECTED]:~/Documents/sage-3.1.4/local/bin$ /usr/bin/python Python 2.5.2 (r252:60911, Jul 31 2008, 17:28:52) [GCC 4.2.3 (Ubuntu 4.2.3-2ubuntu7)] on linux2 Type "help", "copyright", "credits" or "license" for more information. >>> import sys >>> from sage.all import * >>> var('z') z >>> integrate(1/z, z) log(z) >>> But not so from within python-on-lisp. Below the complete log. But actually, the first warning occurs already when importing sys (I have little python experience and no idea what sys contains) sys:1: RuntimeWarning: Python C API version mismatch for module pol: This Python has API version 1013, module pol has version 1011. As far as I understand python on lisp, it provides an interface to the python library: (cffi:define-foreign-library python-library (:darwin (:framework "Python")) (:unix (:or "libpython2.5.so.1.0" "libpython2.4.so.1.0" "libpython2.3.so.1.0")) (:windows (:or "python25.dll" "python24.dll" "python23.dll") ) (t (:default "libpython"))) Sage comes with it's own python, however, without a library. On the otherhand, above I demonstrated that sage also works with the python interpreter that comes with kubuntu. (maybe it needs the interpreter, and the library is not sufficient?) Help would be greatly appreciated. Martin [EMAIL PROTECTED]:~/Documents/sage-3.1.4/local/bin$ sbcl This is SBCL 1.0.11.debian, an implementation of ANSI Common Lisp.
