Actually this is not a good idea because then, every time you update
your system, you get the slow version.
In my opinion the fact that guix makes it easy to build a package on
the user machine is really a key advantage over other package
managers/distributions, for a few, somewhat special packages, ATLAS
being one. It would really be a pity to give up such nice a feature
to spare some build time (ca. 10 min. on my system from 2007).

Could you make the python-wrapper change a separate patch?

The other option would have been to add ‘python’ to ‘propagated-inputs’,
which would also have taken care of sub-directories other than lib/.
As a side-effect, it would also pull in the ‘python3’, ‘pydoc3’,
etc. commands, but I think it cannot hurt.
WDYT?

These variables are unused and not needed, so they can be removed.

Ah, you are right. I thought that 'package-with-python2' would change
all input prefixes from 'python' to 'python2'.
Please note that this patch will NOT build until the 'python-wrapper'
will be applied (but I tested it again with my previous
'python-wrapper' patch). It is my understanding that Andreas will look
into the 'python-wrapper' patch at a suitable time.

Fede

In the mean time version 1.9.1 was released. With this release I
noticed that the pdf documentation gets updated and therefore the hash
changes and breaks the package. For this reason I think that, as you
suggested before, we should build the documentation locally. As
mentioned before, this requires matplotlib and matplotlib requires
numpy. So I will make a numpy package without documentation and use
it as input to matplotlib as you suggested. I'm thinking of calling
this 'numpy-bootstrap' and of not exporting it (use 'define' instead
of 'define-public'). I now got matplotlib building and able to
generate its own documentation, but would like to add the pygtk
backend before supplying a patch for review.

Fede

I do not think we should go this route and instead add the propagated
input "python".
In any case, these should be two separate patches.

Yeah, that’s right. Let’s forget about the generic version until
someone has a more compelling argument in favor of it.

Can these manuals be built from source?
If they can’t, then that’s non-free documentation.
If they can but the process is tedious, then it’s OK to leave it that
way with a TODO, and also a comment stating what its license is.
> + (inputs

This is because Python is not added to ‘LIBRARY_PATH’, right?
I think this is fixed by this patch:

As discussed in the other thread, this should probably be the generic

Use ‘alist-cons-before’ instead of calling the original ‘build’ phase (I
think this was discussed before and there was rough consensus on that.)

Just use (string-append ,name "-" ,version) so the ‘package-name’

Use the ‘copy-file’ procedure instead of calling ‘cp’.

Normally this will no longer be needed if the patch above solves the
problem.

I get error messages that matplotlib is missing. I started looking at
matplotlib as well, but I've found that, for the TkAgg back-end, it
needs TKinter which is part of the standard python libraries and it is
built if, during the build phase, tk is available. The current python
package does not build that library (no tk). In fact, I would like to
add it to be able to move forward with matplotlib :-)
For the other back-ends some packages are missing (python-gtk, Qt, ...)
Another annoying problem is that matplotlib needs numpy, thereby
creating a dependency loop (although only for the documentation).

I've not seen any license statement specific for the documentation.
But, given that the source is distributed with the code, can't we just
assume it is the same license?

Actually it does not. The "...-python-numpy-1.9.0-guile-builder"
still shows that only the python-wrapper is imported. The wrapper does
not include the libraries.

I think that as a temporary situation this is OK. However, in my
opinion it does not make much sense to have a separate sub-optimal
package. I would like to propose to add specific flags to a single
atlas package and, once the new "local-build" flag will be available,
we will remove those flags.

that's much better :-)

The reason that made me use 'cp' instead of 'copy-file' is that the
documentation states that the return value of the latter is not
specified and I'm still not familiar with Guile exception handling.
However, I see many places where 'copy-file' is used without any
'catch'. In principle this should never fail. If it is OK, I will do
the same.

Actually the check phase needs to be moved after the install one (see
comment). That's the reason for this two step approach.
Thanks for the comments.

Heh, OK. Then can you just summarize that in a comment with TODO, to
give the reader an incentive to look at it? :-)

If it’s only to build the documentation, we should be able to handle it
easily (by first building a documentation-less variant of numpy, for
instance.)

Ah right. And what if you again remove Python from ‘inputs’, and add
#:python ,python
to the arguments?
That means it will use the actual Python 3.x package, not the wrapper,
so everything will be visible. The downside is that there will be no
‘python’ command, only ‘python3’.
Perhaps the right fix will be to change ‘python-wrapper’ to symlink the
‘lib’ sub-directory of ‘python’.

Yeah.
After some more thought, I’ve finally bit the bullet:
1. Commit 77b0ac9 adds the #:substitutable? flag to gnu-build-system.
2. Commit f15615b uses it for ATLAS.
It may still make sense to have the non-optimized version for those who
do not need performance and do not want to build locally maybe, WDYT?

‘copy-file’ will throw an exception if something goes wrong; since the
exception is uncaught, the build process will fail.
That’s usually the behavior that we want, so I think it’s best.

Well, as you say, it does not find the 'python' command and stops with
an error. I think that fixing the command name is even worse that
having python as input.

It was also suggested to make python a propagating input of the wrapper.
https://lists.gnu.org/archive/html/guix-devel/2014-10/msg00303.html
In my opinion, one of these two fixes would be desirable.

Wow! That was quick. Thanks!

Personally my main use of ATLAS is through numpy/scipy. Therefore I
would like to be able to use a good performing ATLAS with those
packages. If that needs a manual installation step, that's fine with
me.
In principle we could make a second package and add a suffix to the
version number such that the general binary version takes precedence.
To get a locally built library one would then have to give an explicit
ATLAS version to guix. Or, do you have other approaches in mind?

There was a related bug: ‘guix build atlas’ and similar would tell you
that atlas will be downloaded, but in fact it would be built locally as
intended.
Commit d2d0514 fixes that.

As already stated, I think we should add python as a propagated input to
python-wrapper. The symlinks are just needed between the differently named
python and python3.
Should we give this a try?

So we should add tk as an input to the python package?

That would be great! In this way the python package should build the
Tkinter library which currently is missing.

Okay. I think I should do this together with the changes to python-wrapper
in the python branch to be created. For both python-2 and python-3?

FTR, this patch isn’t needed at all. What mattered here was to fix
‘python-wrapper’ to have a lib/ sub-directory, which Andreas has just
done in ‘wip-python’.
