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

I've checked the homepage of lapack-atlas and it says
At present, it provides C and Fortran77 interfaces to a portably
efficient BLAS implementation, as well as a few routines from LAPACK.
This does not seem as a *full* lapack implementation as called for in
the Description field above.
Therefore I am leaning towards the installation of the lapack-reference
package instead. This what an emerge for lapack-reference would do
->emerge --pretend --verbose lapack-reference
These are the packages that would be merged, in order:
Calculating dependencies... done!
[ebuild N ] sci-libs/lapack-config-1.0.1 0 kB
[ebuild N ] sci-libs/blas-atlas-3.7.11 USE="doc -debug" 1,991 kB
[ebuild N ] sci-libs/lapack-reference-3.0-r1 USE="-debug -ifc"
4,935 kB
I suppose since the -ifc flag is the default, the intel compiler will
not be called and that the gcc gfortran (G95) compiler will. Is this a
correct assumption? Also what is the lapack-config package doing exactly
since the blas-config package is not pulled in.
Thanks,
