Again: Python Error <No module named Tkinter>

Hello to all,

I try straight to start python idle. I get the following messages:

root@om-gta02 ~ $ idle
Traceback (most recent call last):
File "/usr/bin/idle", line 3, in <module>
from idlelib.PyShell import main
File "/usr/lib/python2.6/idlelib/PyShell.py", line 14, in <module>
import macosxSupport
File "/usr/lib/python2.6/idlelib/macosxSupport.py", line 6, in <module>
import Tkinter
File "/usr/lib/python2.6/lib-tk/Tkinter.py", line 39, in <module>
import _tkinter # If this fails your Python may not be configured for Tk
ImportError: No module named _tkinter

On my Freerunner the following modules are installed:

python-idle - 2.6.4-ml8.1.4
python-tkinter - 2.6.4-ml8.1.4
libtcl8.4-0 - 8.4.19-r4.4
libtk8.4-0 - 8.4.19-r0.4 (manually downloaded by http://build.shr-project.org/shr-testing/ipk-pre-gcc-4.4.3/armv4t/ and installed because it's not (more?) contained in http://build.shr-project.org/shr-testing/ipk/armv4t/)

The references from the thread "Python Error <No module named Tkinter>" did not help me. Who can help?

Sincerly
Sferic

Please don't use ipk-pre-gcc-4.4.3, it's only temporary dir crated
before syncing new feed built from scratch with newer gcc and can be
removed soon.

And libtk8.4-0/python-tkinter is built properly only when there is tk
built before python recipe (which is ensured by tk in DISTRO_FEATURES
which we're not using). Even when I rebuild it now, package version
won't be changed and you will have to -force-reinstall it.

Regards,

Re: Again: Python Error <No module named Tkinter>

Thanks for the reply.

But what does this mean? (Apology for the stupid question. I am new in this business...)

Do I have to wait for a recompiled version of python-tkinter (which I have to reinstall with the option --force-reinstall)? Or can't I use python idle at present? I removed libtk8.4-0 from ipk-pre-gcc-4.4.3 in any case.

Yes, exactly. The package version will stay the same so opkg upgrade
won't install fixed version for you automatically, but there will be
libtk available in ipk/armv4 and python-tkinter will be probably fixed.

opkg install -force-reinstall python-tkinter libtk8.4
should work.

It's already built and will be in feeds in an hour or so with other
upgrades. If you see fso stuff upgrade with opkg upgrade then tk is
already there.

Re: Again: Python Error <No module named Tkinter>

Did I notice that I have installed SHR Testing? I believe, only indirectly by the indication of the path of gcc-pre-4.4.3.

So far I didn't notice an update of /shr-testing/ipk/armv4t - is it because of that? And will python-tkinter in /shr-testing/ipk/armv4t be renewed and libtk8.4 be supplemented?

Greetings

Ah sorry I didn't notice, there was similar temporary dir in
shr-unstable dir (already removed it).

OK I'll build it with tk also in shr-t. (expect it to be in feeds in an
hour or so).

Re: Again: Python Error <No module named Tkinter>

Thank you very much for updating!

The download and installation of python-tkinter and libtk8.4-0 have worked without problems.
But I get at the start of python idle a new error message:

root@om-gta02 ~ $ idle
Traceback (most recent call last):
File "/usr/bin/idle", line 3, in <module>
from idlelib.PyShell import main
File "/usr/lib/python2.6/idlelib/PyShell.py", line 36, in <module>
import Debugger
File "/usr/lib/python2.6/idlelib/Debugger.py", line 2, in <module>
import bdb
ImportError: No module named bdb

I have installed python-debugger - now I got the following message after calling idle:

root@om-gta02 ~ $ idle
Traceback (most recent call last):
File "/usr/bin/idle", line 5, in <module>
main()
File "/usr/lib/python2.6/idlelib/PyShell.py", line 1386, in main

File "/usr/lib/python2.6/lib-tk/Tkinter.py", line 1643, in __init__
self.tk = _tkinter.create(screenName, baseName, className, interactive, wantobjects, useTk, sync, use)
_tkinter.TclError: Can't find a usable tk.tcl in the following directories:
/usr/lib/tcl8.4/tk8.4 /usr/lib/tk8.4 /lib/tk8.4 /usr/library /library /tk8.4.19/library

This probably means that tk wasn't installed properly.

Now I found, that I have to install Tk and get the following:

root@om-gta02 ~ $ idle
Traceback (most recent call last):
File "/usr/bin/idle", line 5, in <module>

File "/usr/lib/python2.6/idlelib/PyShell.py", line 1386, in main

This probably means that tk wasn't installed properly.

If I understand correctly tk.tcl is missing a button or a scroll wheel. I am finished with my opportunities. What can I do now? (Do I have to do without idle? Thanks in advance

Re: Again: Python Error <No module named Tkinter>

OK, a break for the night is a good idea, if one can think of nothing more:

Today I removed the MouseWheel-Sections from /usr/lib/tk8.4/listbox.tcl and /usr/lib/tk8.4/text.tcl. After this idle starts and seems to be usable (I will try later and report my experiences).

Would it be a good idea to remove those sections permanently, so that remain idle even after an update of tk?

Anyway - Many thanks to Martin Jansa

Sorry I cannot comment on tk issues and I don't even know
python-idle/python-tkinter.

> Anyway - Many thanks to Martin Jansa

Well now it's "fixed" only till next rebuild from scratch, but I'll add
"tk" to DISTRO_FEATURES (proper fix) if it doesn't add much to image
size or dependency tree.

Hi,

pushed that tk DISTRO_FEATURE
http://git.openembedded.org/cgit.cgi/openembedded/commit/?id=fa21428ef11bb9b13a276c113e533e951301ecec
and there is newer tcl/tk 8.5.8 in oe.dev
http://git.openembedded.org/cgit.cgi/openembedded/commit/?id=e92042a4e03b0d40dab3886867340059e6fafcb3

it's building now in shr-u feeds (ETA few hours), so if you're willing to test
it with newer tk, please try shr-u (this won't be in shr-t soon).

Cheers,

Re: Again: Python Error <No module named Tkinter>

Thanks for the hint.

I have looked at tk_8.5 and above all at listbox.tcl and text.tcl. Both files contain the section MouseWheel (from line 178 in listbox.tcl and from line 446 in text.tcl). These sections in tk_8.4 caused the error messages in idle (before I commented out the lines). I therefore believe that the newer version of tk does not work (without having tried it).

In the meantime I have tested idle. And I've found that I can't use the menus with the stylus on the touchscreen. I can select menu items, but I can't execute the commands. This is possible only through the keyboard shortcuts when they are defined for the menu items. I therefore believe that the MouseWheel-sections have to be replaced by something like touchscreen-action. Who can do such a thing? I can't do this, because I can't program ...

Greetings
