There is also the issue that TkVersion == 8.5 is underspecied -- there
are multiple bugfix releases.
root.call('info', 'patchlevel') returns more detailed info.

Re: tkinter errors out without clear message
Hi Terry, I managed to find the problem! As you suggested, I installed newer version of tk/8.5.15. Then, the same test will still fail, but the error message has content now. It complains about missing font. I did some google, then fix it by installing "dejavu-sans-fonts". I laughed when I found the problem, and indeed, this small bug has bothered me for a whole day. Thanks again for your help. I would probably spend hours and days before even think about trying newer version tk. :) Best, Kai On Wed, May 21, 2014 at 1:55 PM, Kai Song wrote: > Hi Terry, > > Thanks for your reply! > > >> Nasty.

However, I tried on other SL6 machines, they have the same version (SL6.5), and same tests work on those systems. So, the python/2.6.6 and tk-6.5.7 should work... I can't recall how I set up these systems differently, but I am worried that there are other non-tk/python related issues... I am just curious if there are other ways to debug this other than python gdb? Thanks again for your help! Kai -- Kai Song 1.510.495.2180 1 Cyclotron Rd.

The python version is the SL6 default Python/2.6.6, and the tkinter is also from SL6 repository, "tkinter-2.6.6-51.el6.x86_64". I was able to import _tkinter and Tkinter, and the _test() will bring up an empty window, but it will then fail without any actual error message. I think it's when it tries to create buttons. I tried to use python gdb to debug through the code, but It's hard to pin point the problem. _tkinter.TclError Nasty. I have seen TclErrors, but with a message. Here is a simple test I just ran (from within Idle) on Win7, 2.7.6. >>> import Tkinter as tk >>> root = tk.Tk() >>> tk.Label(root, text = 'label text').pack() >>> tk.mainloop() and I see a window with label with text. tk._test() works too, with slightly more involved window. You said you tried 2.7.5. I believe 2.7.6 has some tkinter bug fixes. There is also the issue that TkVersion == 8.5 is underspecied -- there are multiple bugfix releases.
