I recently built (using David Cournapeau's garnumpy) numpy and scipy using ATLAS 3.7.33, gfortran, gcc 4.1.2, SUSE 10.2 (x86 kernel 2.6.18.2-34-default), and python 2.5: python Python 2.5 (r25:51908, Nov 27 2006, 19:14:46) [GCC 4.1.2 20061115 (prerelease) (SUSE Linux)] on linux2 Type "help", "copyright", "credits" or "license" for more information. >>> import numpy >>> import scipy >>> print numpy.__version__ 1.0.1 >>> print scipy.__version__ 0.5.2 >>> numpy.test(level=1,verbosity=2) [...] Ran 526 tests in 0.432s OK >>> scipy.test(level=1,verbosity=2) [...] Ran 1596 tests in 2.942s OK There doesn't appear to be a problem with recent versions of the software. In particular, ATLAS 3.7.33 does not cause an error. Is there some reason for you to use such old software? (gcc 3.3.1 & kernel 2.4.21)? What platform are you building for? -rex _______________________________________________ Numpy-discussion mailing list Numpy-discussion@scipy.org http://projects.scipy.org/mailman/listinfo/numpy-discussion
