Okay, here is the full scoop: * The multi-threaded ATLAS is always tried first. This doesn't work for you since you compiled your Python without pthreads. * The standard library directories (/usr/lib, /usr/local/lib, etc.) are tried along with fairly standard ATLAS library directories, too (/usr/lib/atlas, /usr/local/lib/atlas). * Consequently, the multi-threaded libraries in /usr/local/lib/atlas are picked up before the version that you want. Here is how to override this (I think): Set the environment variable PTATLAS=None and then run the build. E.g. $ export PTATLAS=None $ python setup.py build -- Robert Kern "I have come to believe that the whole world is an enigma, a harmless enigma that is made terrible by our own mad attempt to interpret it as though it had an underlying truth." -- Umberto Eco _______________________________________________ Numpy-discussion mailing list Numpy-discussion@scipy.org http://projects.scipy.org/mailman/listinfo/numpy-discussion
