I think we need to add tcl and tk to the inputs, and add the
corresponding "-I" and "-L" flags to the configure flags. The issue is
that tk depends on Python (through libx11, which depends on libxcb,
which depends on Python), so we end up with a circular dependency
leading to what I reported in
I think we should:
- rename the Python package to "python-without-tkinter" or
"python-minimal" and use that as a dependency in xorg.scm;
- define a "python" package that would inherit the "minimal Python"
package and add the dependency on tcl/tk to it.
WDYT ?

How frequently do Python packages rely on the availability of Tkinter?
I’m asking because it might be that we could keep the default Python
without Tk, and only use the Tk-enabled Python for the few packages that
need it, if it’s rare enough.
WDYT?

No, we do not want that. Users who install Python expect to be able to
import tkinter, since it is part of the standard library.

OK. Then we effectively need to proceed as you suggest: Build
python-minimal (which does not depend on Tk), build Tk, and then build
python.
But we should make sure that python-minimal is not retained, if
possible.

And maybe this python-minimal could be smaller than the current python,
in the sense of "minimal"?

This error message comes from Tcl, in file ‘auto.tcl’, procedure
‘tcl_findLibrary’.
We’d need to find where the call comes from and hard-code a search path
in there maybe?

Yes. That wouldn’t help for Python though, where we need to hard-code
the search path somehow.

I don’t think it would help because Python finds Tcl and Tk anyway.

“This patch hard-codes the Tk library directory during package

OK with this change. Thanks for providing a quick fix! :-)
Could you commit it in a new ‘tk-update’ branch?
At the same time, I think we should move tkinter*.so to a separate
output of the Python packages; I think it’s a matter of moving the .so
to a separate output, literally. Would you like to give it a try?
Thanks!

Tkinter moved to separate output
(name . ???)(address . iyzsong@openmailbox.org)
87k2picp2z.fsf_-_@gnu.org
In ‘tk-update’ the ‘python’ packages now have a separate ‘tk’ output for
Tkinter (adding ~50 MiB to the closure of Python.) I’ve tested it along
these lines, for 2.x and 3.x:
guix environment --ad-hoc python python:tk --pure -- python
> import Tkinter
> root = Tkinter.Tk()
One thing I haven’t checked is whether some packages need to have an
additional python:tk input. Matplotlib maybe? Federico?
I plan to have Hydra build that branch once we’ve checked that.
Thanks,

Yes, given that the back-end currently used by matploblib doesn't
work, I would change that by using 'Tkinter'.
Since you are at it, I would also change the default back-end by
changing 'GTK3Agg' to 'TkAgg' in the following snippet:
(lambda (port)
(format port "[rc_options]~%
backend = GTK3Agg~%")))))
I'm not convinced that having 2 versions of packages (a "normal" and a
"minimal" one) is a good idea. The reason is that you often end up
downloading both instead of just one. As one example, I just
downloaded 'vlc' and I noticed that it downloaded both 'cups' and
'cups-minimal'. Similarly, for python, anyone needing 'Tkinter' will
end up with 2 versions in the store.

OTOH I see that Matploblib already depends on GTK+ 3.x and
python-pygobject, so maybe it’s best to stick to GTK+ by default?

The ‘minimal’ variants are there to break cyclic dependencies most of
the time. This is the case for cups/cups-filters and Python/Tk.
At run time, cups indeed depends on cups-filters, which depends on
cups-minimal. In that case, as you say, we end up downloading those two
variants. But there’s not much of a choice, as was discussed during the
initial review:
Conversely, python does not depend on python-minimal. So python-minimal
is here just to break the cycle with Tk/libxcb, as noted in python.scm
and discussed in:
As for Tkinter, it is in a separate “tk” output, which users can choose
to install or not. The “tk” output contains a single file, but it pulls
in Tcl/Tk.
I hope this clarifies things.
Thanks for your feedback,
Ludo’.

Unfortunately, the back-ends based on GTK+ are broken and I didn't
manage to find how to fix the problem.
That's why I'm looking forward to get Tkinter :-)

It does not work. It can't find the tcl/tk header files:
...
tkagg: no [The C/C++ header for Tk (tk.h) could not be
found. You may need to install the development
package.]
...
With the attached patch it does find the headers, but then it fails at
link time.

Looking into the failed build directory, it seems that PKG_CONFIG_PATH

The attached patch fixes the problem and I can now plot with TkAgg :-)
Thanks for making Tkinter available!

Nice!
Please make sure to add the patch to gnu-system.am, but otherwise looks
great!
Thanks for fixing it!
I gather this addresses http://bugs.gnu.org/20888,right?

Well, it partially solves it:
Now there is a working backend suitable for interactive plotting which
is enabled by default. However, the 'GTK3Agg' backend is still there
and still not working. At some point it would be nice to have it
working as well.
