No, using the standard bash launched with cygwin.bat.

Same behavior, wish84 seems to hang. However, running wish84 directly from
the Windows console results in normal execution/behavior.

Jeff,
Can you reproduce the hang by running 'bash -c wish84'? How about 'bash
--login -i -c wish84'? If so, the problem might be triggered by the
presence of bash. WAG below.
<WAG>
It's possible that wish84 uses some signals that aren't correctly
interpreted by bash in 1.5.4. There were some signal fixes in the latest
Cygwin snapshot -- please try it: <http://cygwin.com/snapshots/>. If you
get the same behavior with the snapshot, please run wish84 under strace.
It would help immensely if you tried interpreting the output somehow
(i.e., does it hang or loop? if it hangs, what are the last actions? if
it loops, what does it loop through?). You may need to strace 'bash -c
wish84' instead.
</WAG>
Hope this helps,
Igor

The following attempts produce the same hanging behavior:
"bash -c /bin/wish84" from a DOS command shell and a bash (--login -i)
shell
"bash --login -i -c /bin/wish84" from DOS shell nd a bash (--login -i)
shell
However,
"strace -w /bin/wish84" (from a bash shell) works! (Also confirmed by
Felix von Hove)
I haven't tried the latest snapshot due to learning curve (in progress).

This validates my WAG somewhat. Does "strace -o wish.strace bash -c
wish84" reproduce the hang? The reason is that, IIRC, strace uses Windows
exec mechanisms, rather than Cygwin's, so you need to force Cygwin's exec
by running bash first.

Also try using a large buffer with strace:
strace -b 1000000 -o wish.strace bash -c wish84
since the large buffer sometimes helps unmask problems which were "fixed"
by the slowdown incurred by running strace.

I get it...
"strace -o wish.strace -w bash -c /bin/wish84" reproduces the hang (after
about 1MB of log file). My (naive) take on the relevant end of the log file
seems to show that wish84 is busy searching paths for a file without any
interesting error messages. However, about 1/3 through the attached file,
_cygwin_istext_for_stdio seems to report an error. The last 100 lines of
the strace output are attached.

Same hang is observed as the regular ol' "strace bash -c wish84"...

I would like to report the same Tcl/Tk wish shell hang problem that Jeff
Russell brought up. I followed the thread on this issue and have been left
confused as to how to solve it.
Recap: wish84 fails to bring up the command line shell while instantiating the
window frame correctly. Running "strace -w /bin/wish84" avoids the problem
(through recourse to Win exec rather than Cygwin exec). An error report
excerpt from strace was supplied by Jeff (11/18/2003); I have similar errors.
The problem remains on snapshot cygwin1-20030919.dll.
I need to call wish from bash or equivalent - is there a workaround or bug fix?

Are you running bash under rxvt? Have you tried "wish" from a Windows
console running bash?

The Tcl/Tk wish shell (wish84.exe) does not properly start/execute under
bash.
When launched, the Tk canvas window appears, but the command prompt window
never opens. The wish84.exe application seems to hang (an hour-glass appears
with the mouse over the Tk canvas window; a Ctrl-C from bash is ignored, but
a click on the tk-window close results in a Windows pop-up saying the
application is not responding, from which it can be "ended now").
The Tcl-only shell (tclsh) seems to execute properly.
The wish application properly executes when launched from the Windows
Start->Run menu.
Relevent packages: tcltk-20030901-1, cygwin-1.5.4-1, and bash-2.05b-15 (on
Win2k).
I'm not sure how investigate this...some things I tried:
* recompiled Tcl/Tk from the 20030901-1 source distribution, same behavior.
(Note: a minor fix is required in the file tcl/generic/tclCmdAH.c due to a
symbol conflict with "FILE_EXISTS".)
* recompiled Tcl/Tk from the 8.4.4 source distribution, same behavior.
(Note: per the instructions that recommend use of the mingGW stuff.)
* tried running "dumper" on the wish84 process, and dumper itself core
dumped with a segmentation fault.
* if I start wish84 specifying a script with the line "console show", the
console window is opened, but no command prompt appears (as if it were busy
doing something). If commands are typed into the console window, output
appears in the original bash window.
Any ideas?
