11 One more problem related to the new eselect modules from your overlay. I
12 have blas-atlas and lapack-atlas libraries selected using an old
13 blas-config and lapack-config mechanism:
14
15 lespaul ~ # blas-config -p
16
17 Current profiles:
18 F77 BLAS: /usr/lib/blas/f77-ATLAS
19 C BLAS: /usr/lib/blas/c-ATLAS
20
21 lespaul ~ # lapack-config -p
22
23 Current profile:
24 F77 LAPACK: /usr/lib/lapack/f77-ATLAS
25
26 And after merging your updated eselect modules and *-reference packages, I
27 can not switch to them using neither eselect nor blas/lapack-config:
28
29 lespaul ~ # eselect lapack set reference
30 Implementation "reference" already active for libdir "lib"!
31 Failed to switch to implementation "reference" for libdir "lib"!
32 !!! Error: One or more actions have failed!
33 exiting.
34
35 Eselect shows that current lapack and blas are the reference ones:
36
37 lespaul ~ # eselect lapack show
38 reference
39
40 However, this is not true:
41
42 lespaul ~ # ls -l /usr/lib/liblapack.*
43 lrwxrwxrwx 1 root root 24 maj 28 17:20 /usr/lib/liblapack.a ->
44 lapack/atlas/liblapack.a
45 lrwxrwxrwx 1 root root 25 maj 28 17:20 /usr/lib/liblapack.so ->
46 lapack/atlas/liblapack.so
47 lrwxrwxrwx 1 root root 27 maj 28 17:20 /usr/lib/liblapack.so.0 ->
48 lapack/atlas/liblapack.so.0
49
50 Is it a bug?
