Hi, |

While updating sage and python to 4.7 and 2.7, I hit a variation of an |
4 |
old bug (see http://bugs.gentoo.org/195619): scipy compiles with |
5 |
lapack-reference but is unusable. Running in python |
6 |
|
7 |
import scipy.optimize |
8 |
|
9 |
fails with |
10 |
|
11 |
[...] |
12 |
from scipy.linalg import clapack |
13 |
ImportError: /usr/lib64/python2.7/site-packages/scipy/linalg/clapack.so: |
14 |
undefined symbol: clapack_sgesv |
15 |
|
16 |
I tried rebuilding numpy and scipy with lapack provided (eselect) by |
17 |
lapack-reference, blas provided by blas-reference, cblas provided by |
18 |
gsl and with/without clapack with the same result. |
19 |
|
20 |
Then I tried rebuilding numpy and scipy with lapack, blas and cblas |
21 |
provided (eselect) by atlas and scipy worked flawlessly. |
22 |
|
23 |
Should scipy depend on a specific lapack provider instead of a virtual? |
24 |
Enable it at compile time? Is it an unfortunate combination what fails? |
25 |
|
26 |
I can provide build logs if you need them. |

Best, |
