Running in python import scipy.optimize fails with [...] from scipy.linalg import clapack ImportError: /usr/lib64/python2.7/site-packages/scipy/linalg/clapack.so: undefined symbol: clapack_sgesv I tried rebuilding numpy and scipy with lapack provided (eselect) by lapack-reference, blas provided by blas-reference, cblas provided by gsl and with/without clapack with the same result. Then I tried rebuilding numpy and scipy with lapack, blas and cblas provided (eselect) by atlas and scipy worked flawlessly. Should scipy depend on a specific lapack provider instead of a virtual? Enable it at compile time? Is it an unfortunate combination what fails? I can provide build logs if you need them. Best, Marc. --Sig_/iqP.8/y_HQK2YY.62PqzKyn Content-Type: application/pgp-signature; name=signature.asc Content-Disposition: attachment; filename=signature.asc -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.17 (GNU/Linux) iEYEARECAAYFAk3k8KcACgkQu4rFT+k3kmTsnwCgnIUV++WRt91jpewNXELxTwUL SX4An1OcAEWc+3jBncqs7Qf6emL1Kr1c =09KI -----END PGP SIGNATURE----- --Sig_/iqP.8/y_HQK2YY.62PqzKyn--
