TclError: couldn't load library "tix8184.dll"

[Shane Graber]

Hello:

I'm having problems using PyInstaller with a particular program. The
program in question was written using Python 2.4 with Tk and Tix. At
the beginning of my program, I have the following imports:

from Tkinter import *
from Tix import Tk, ComboBox
import tkFileDialog, tkMessageBox
import os, sys, csv
from math import *

After compilation and subsequent running of the program, I will
receive the following error:

C:\Program Files\Pump Head Loss Calculator>plumbing.exe
Extracting binaries
C:\Program Files\Pump Head Loss Calculator\python24.dll
Manipulating evironment

_tkinter.TclError: couldn't load library "tix8184.dll": this library
or a dependent library could not be found

OK.

I am getting a traceback error that tix8184.dll could not be found
when the program is run. However if I edit my PATH and add 'C:
\Python24\DLLs\' the executable will run just fine. It should be
noted that I have Python 2.4 installed on this PC. If I install this
on any PC without Python, I have no options to make this work since
it's dependent on a pre-installed python. The other programs that I
have written that do not use the Tix package run just fine.

Is there a known bug with the Tix package with PyInstaller or did I
not do something right during the build process?

Thanks,

Shane

Just as a follow-up:

I figured out the problem. I had to copy tix8184.dll from C:
\Python24\DLLs to my dist directory as PyInstaller wasn't doing it for
me. Once I did this the program executed just fine.

It looks like a hidden import, since it's executed as a tk.eval(). Basically,
PyInstaller can't know that DLL is required since there is no direct reference
to it.

One question though: is it really enough to copy that DLL? Isn't TIX made of
many TCL files which should be packaged as well within the executable?

Yep, that's all it took to get the executable running was copying that
one .dll over to the dist folder. However the only thing I'm using
out of Tix is ComboBox and Control widgets.

...actually it did require copying the entire C:\Python24\tcl\tix8.1
directory to the dist\_MEI in order to get Tix functioning properly.

I filed a bug report accordingly:
