Problem with Python and _tkinter on SunOS system

P: n/a
Hello,

I try to launch a Python script on SunOS system but I have this error:

"""Traceback (most recent call last):
File "ihm1_1.py", line 3, in ?
from Tkinter import *
File "/opt/sfw/lib/python2.3/lib-tk/Tkinter.py", line 38, in ?
import _tkinter # If this fails your Python may not be
configured for Tk
ImportError: ld.so.1: python: fatal: relocation error: file
/usr/local/lib/libtk8.4.so: symbol __eprintf: referenced
symbol not found"""

At the beginning, some people told me that it was due to a
different GCC version used for Python compilation and Tcl/Tk
compilation (because of "__eprintf" error).

=>But the GGC version was the same for the Python and Tcl/Tk
compilation on my system: GCC 3.3.2.

Then, I tried to find a solution and this is what i've found
on the Python web site:
"""
Step 1 - can _tkinter be imported?
Try the following command at the Python prompt:
import _tkinter # with underscore, and lowercase 't'

* If it works, skip to the next step.
* If it fails with "No module named _tkinter", your Python
configuration needs to be modified to include this module
(which is an extension module implemented in C). Edit
Modules/Setup (read the instructions at the top, search for
_tkinter, read more instructions there, and follow the
instructions) and rebuild and reinstall. Make sure to
enable the _tkinter module as well as the TKPATH variable
definition.
* If it fails with an error from the dynamic linker, see
above (for Unix, check for a header/library file mismatch;
for Windows, check that the TCL/TK DLLs can be found)."""

But I don't understand what "Edit Modules/Setup" means? Where is it ?
What is TKPATH? How can I modify it?

Do you think my problem comes from that "Edit Modules/Setup" ? Or do you think that there is something else wrong ?

thanks.

Does tcl/tk work? I.e., if you run wish or wish8.4, does it work? It seems that
it can be a problem with a shared object used by libtk8.4.so that cannot be found.

You didn't compile your Python interpreter yourself, did you? The Setup file is
in Python's source directory under the Modules directory. Open this file in a
text editor and look for a line containing _tkinter. Read the comments after
this line; they should be self-explanatory. If you modify the file, you'll have
to re-compile your interpreter.

Maybe, maybe not... Apparently, the tk library is found, so Python seems to be
correctly configured. Maybe the problem is in the tcl/tk installation, but you
should see that by running wish.

Hello,

Thanks for your answer. I tried to run wish and wish8.4 and it both
works! (a little screen appears on the screen). So, apparently Tcl/Tk
works?!

It's right that I didn't compile Python myself because I'm in training
period in a big company and I use SunOS from the network. But the
Network administrator doesn't know exactly why Python doesn't run on
SunOS, so I try to find a solution by my side...

So, I will told him to look at the Setup file and to do the right
modifications.

Thanks.
