cygwin python with Tkinter and pexpect module

[=?ISO-8859-15?Q?J=F6rg?= Maier]

Hey guys,

i have a big problem using Tkinter and pexpect in cygwin. i try to program
an winscp-like rsync Program for all posix Platforms (linux, macosx,
cygwin). i got a class SslConnection with a method listDirectory that gives
back a list of an remote directory using pexpect. this method works in
linux, it works in cygwin-python from command-line, but invoked in an
Tkinter-Program i got the strange Exception:
E:\cygwin\bin\python2.3.exe: *** unable to remap E:\cygwin\bin\tk84.dll to
same address as parent(0x710000) != 0xC20000 28 [main] python 604
sync_with_child: child 1848(0x63C) died before initialization with status
code 0x1
3133 [main] python 604 sync_with_child: *** child state child loading
dlls
E:\cygwin\bin\python2.3.exe: *** unable to remap E:\cygwin\bin\tk84.dll to
same
address as parent(0x710000) != 0xC20000
174653 [main] python 604 sync_with_child: child 1932(0x5F8) died before
initial
ization with status code 0x1
203190 [main] python 604 sync_with_child: *** child state child loading
dlls

dont know what to do , gui-program is running under linux. Any ideas? Is
this a bug in cygwin tcltk?

thanks for every advice,
joerg

Jörg,

it works in cygwin-python from command-line, but invoked in an
Tkinter-Program i got the strange Exception:
E:\cygwin\bin\python2.3.exe: *** unable to remap E:\cygwin\bin\tk84.dll to
same address as parent(0x710000) != 0xC20000 28

No, you have been bitten by the Cygwin fork() issue:

The solution is to install the rebase package via Cygwin's setup.exe and
rebase your system.
