Hello, |

Is lapack ready for gcc-4.1.1? On my system profile 2006.1, these are |
4 |
the options for lapack install |
5 |
|
6 |
->emerge --search lapack |

I've checked the homepage of lapack-atlas and it says |
35 |
|
36 |
At present, it provides C and Fortran77 interfaces to a portably |
37 |
efficient BLAS implementation, as well as a few routines from LAPACK. |
38 |
|
39 |
This does not seem as a *full* lapack implementation as called for in |
40 |
the Description field above. |
41 |
|
42 |
Therefore I am leaning towards the installation of the lapack-reference |
43 |
package instead. This what an emerge for lapack-reference would do |
44 |
|
45 |
->emerge --pretend --verbose lapack-reference |
46 |
|
47 |
These are the packages that would be merged, in order: |
48 |
|
49 |
Calculating dependencies... done! |

[ebuild N ] sci-libs/lapack-config-1.0.1 0 kB |
51 |
[ebuild N ] sci-libs/blas-atlas-3.7.11 USE="doc -debug" 1,991 kB |
52 |
[ebuild N ] sci-libs/lapack-reference-3.0-r1 USE="-debug -ifc" |
53 |
4,935 kB |
54 |
|
55 |
I suppose since the -ifc flag is the default, the intel compiler will |
56 |
not be called and that the gcc gfortran (G95) compiler will. Is this a |
57 |
correct assumption? Also what is the lapack-config package doing exactly |
58 |
since the blas-config package is not pulled in. |
59 |

Thanks, |
