Ignore that, I had forgotten to copy the libpython17.a file in c:\Python27\libs on that instance. Building scikit-learn works with the static toolchain. I have failing tests but those are probably not related to the toolchain. -- Olivier http://twitter.com/ogrisel - http://github.com/ogrisel _______________________________________________ NumPy-Discussion mailing list NumPy-Discussion@scipy.org http://mail.scipy.org/mailman/listinfo/numpy-discussion
