1 Hi,
2
3 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.
27
28 Best,
29 Marc.
