#146 fixed Make libusb10 package detect usbcalls.dll David McKenna
Description

Currently, if one uses YUM to install libusb10, or any app that depends on it, it will also insist on installing usbcalls as a dependency (if not already installed by YUM). But anyone who has installed the Arca Noae USB stack will already have the correct version of usbcalls.dll. This creates the potential for a mis-match. It would be best if the YUM version of libusb could detect if usbcalls is already installed, even by another installer, and allow not installing the YUM version of usbcalls.

#147 wontfix tkinter working? ggamba
Description

Hi all,

I installed python-tools package, and it took tkinter package as dependency. But whenever I try to run something from the \Demo\tkinter directory, I always get an error:

C:\usr\lib\python2.7\Demo\tkinter\matt>python 00-HELLO-WORLD.py Traceback (most recent call last):

File "00-HELLO-WORLD.py", line 1, in <module>

from Tkinter import *

File "C:/usr/lib/python2.7/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

Is this expected to work? Any hint?

Thanks a lot Gabriele

#148 fixed python: os.popen doesn't accept backslashes dmik
Description

I discovered a strange problem with os.popen regarding paths containing backslashes:

import os

gcc_exe = "C:\\usr\\bin\\gcc.exe"

print "["+repr(gcc_exe)+"]"

# [1] This works
exists = os.access(gcc_exe, os.X_OK)
print "exists", exists

if exists:

    # [2] This works too, if uncommented
    #os.execl(gcc_exe, "gcc", "-dumpversion")

    # [3] This doesn't work :(((
    out = os.popen(gcc_exe + ' -dumpversion', 'r')
    try:
        out_string = out.read()
        print out_string
    finally:
        out.close()

This gives the following output here:

D:>python popen.py
['C:\\usr\\bin\\gcc.exe']
exists True
C:usrbingcc.exe: not found

Both [1] and [2] cases work, but case [3] does not. Seems that some extra string evaluation happens before the string is passed down to the popen implementation (as if str(gcc_exe) were called) which effectively kills backslashes.
