I tried etcl on a nokia 770.
copied to /var/lib/install/usr/bin
executed etcl from an xterm
Tcl runs fine
Tk has problems:
package require Tk
brings up a gray window over the xterm.
I can get the xterm running Tcl back by selecting its icon
I can get . back using:
wm withdraw .
wm deiconify .
"toplevel .w" works, the windows act like .
"frame .w.c" nothing visual happens, but window exists according to
[winfo]
"pack .w.c" does not change anything but does not bomb
button .b -text b -command "puts hi" reboots after several second delay
"label .w.c.lbl -text label" reboots after several second delay

Thanks for giving it a try, since I don't have such device, and could
only test it on device with kdrive.

Just a doubt: did you download the executable very early after having
been announced?

On our site home page (http://www.evolane.com/), I explain I pushed a
wrong executable online for all linux platforms (x86 and arm). They were
linked against a static X11 library compiled with support for
dynamically loadable Xcursor support. When trying to change cursor in
Tk, an incompatible libXcursor.so.1 was searched and eventually loaded,
causing a segfault. Because there was a freshmeat announcement pending,
I didn't increment the release number, hoping there has been no download
in the meantime, but I guess this was definately a bad idea :-(

Could you please check the executable you used is the same available now
for download. Please let me know if it fixes the problem.

:-(

Since it works fine on others arm-linux distributions we could test it
in, I will have to either find a way to get access to a nokia 770, or
provide someone (you? ;-)) a debug version and sources to investigate
this. Hmmm... maybe if you could already run in inside strace, and send
me the output, this could give me some hint.

During next couple of days, I will focus on restoring and improving
support for older WinCE 3.0 devices, then I will be able to focus on
this target architecture (installing the maemo SDK will probably be a
good starting point :))

Yep - the issue you describe is because eTcl isn't "Hildonised". That
is, it doesn't support the WM APIs to deal with overlaying windows,
menus, etc.

Thanks to Meredydd we've got a partially Hildonised Tk and I'm doing a
bunch of work trying to get sound support going (and rapidly going crazy
in the process).

ps Eric, did you ever release the code that will enable us to get
vanilla tclkit working on Windows Mobile?
