[PATCH] Add LAPACKE

[PATCH] Add LAPACKE

[Ricardo Wurmus]

Hi Guix,

here's an alternative to the patch provided here:

    https://lists.gnu.org/archive/html/guix-devel/2016-06/msg00099.html

Instead of building LAPACKE as part of the lapack package this patch adds a
new package "lapack-with-lapacke".  I did this because an increase in closure
size of 20MiB is a little much for a commonly used package, in my opinion.

A third option would be to move LAPACKE to its own output.

WDYT?

A patch is attached.  It produces two output directories:

  /gnu/store/40g0xqcikbz6ya7h2gbyj8gck043ajl8-lapack-3.5.0-lapacke
  /gnu/store/lqnm7fmpz3si0rgyqz1pzax4ipa25xlx-lapack-3.5.0

The closure of the lapacke output is larger, as expected:

$ guix size /gnu/store/40g0xqcikbz6ya7h2gbyj8gck043ajl8-lapack-3.5.0-lapacke
store item                                                       total    self

total: 97.2 MiB

But the plain output is unchanged:

total: 71.4 MiB


I have yet to test that this works as expected with the package I’m
working on.

This works.  I think this is the best of the available options.

The 20 MiB increase shown in the message above correspond mostly to
gcc:lib, which is present anyway, so I would say it’s acceptable.

WDYT?

Well, in this case I’ll just apply Dave’s patch then (see email in the
ML archive).

“guix refresh -l lapack” shows me that 51 packages are affected, which
results in a rebuild of 86 dependent packages.  Okay to push to master?
