ed,
Are you able to use the python interactive shell on your mini2440? I had
a similar problem in that python would fail to even start (resulting in
an alignment trap).
For me simply removing /usr/lib/python2.6/lib-dynload/readline.so kept
python from dying on startup.

I am trying to run a simple hello button python program using pygtk.
I have built a minimal-gpe-image for the mini2440.
But when I try and run the helloworld.py from the Pygtk tutorial.
=========================================================
#!/usr/bin/env python
# example helloworld.py
import pygtk
pygtk.require('2.0')
import gtk
class HelloWorld:
# This is a callback function. The data arguments are ignored
# in this example. More on callbacks below.
def hello(self, widget, data=None):
print "Hello World"
def delete_event(self, widget, event, data=None):
# If you return FALSE in the "delete_event" signal handler,
# GTK will emit the "destroy" signal. Returning TRUE means
# you don't want the window to be destroyed.
# This is useful for popping up 'are you sure you want to quit?'
# type dialogs.
print "delete event occurred"
# Change FALSE to TRUE and the main window will not be destroyed
# with a "delete_event".
return False
def destroy(self, widget, data=None):
print "destroy signal occurred"
gtk.main_quit()
def __init__(self):
# create a new window
self.window = gtk.Window(gtk.WINDOW_TOPLEVEL)
# When the window is given the "delete_event" signal (this is
given
# by the window manager, usually by the "close" option, or on
the
# titlebar), we ask it to call the delete_event () function
# as defined above. The data passed to the callback
# function is NULL and is ignored in the callback function.
self.window.connect("delete_event", self.delete_event)
# Here we connect the "destroy" event to a signal handler.
# This event occurs when we call gtk_widget_destroy() on the
window,
# or if we return FALSE in the "delete_event" callback.
self.window.connect("destroy", self.destroy)
# Sets the border width of the window.
self.window.set_border_width(10)
# Creates a new button with the label "Hello World".
self.button = gtk.Button("Hello World")
# When the button receives the "clicked" signal, it will call
the
# function hello() passing it None as its argument. The hello()
# function is defined above.
self.button.connect("clicked", self.hello, None)
# This will cause the window to be destroyed by calling
# gtk_widget_destroy(window) when "clicked". Again, the destroy
# signal could come from here, or the window manager.
self.button.connect_object("clicked", gtk.Widget.destroy,
self.window)
# This packs the button into the window (a GTK container).
self.window.add(self.button)
# The final step is to display this newly created widget.
self.button.show()
# and the window
self.window.show()
def main(self):
# All PyGTK applications must have a gtk.main(). Control ends
here
# and waits for an event to occur (like a key press or mouse
event).
gtk.main()
# If the program is run directly or passed as an argument to the python
# interpreter then create a HelloWorld instance and show it
if __name__ == "__main__":
hello = HelloWorld()
hello.main()
==============================================================
I get the follow error when I run
#python -v pygtkHelloWorld.py
# /usr/lib/python2.6/site-packages/gtk-2.0/gtk/_lazyutils.pyo
matches /usr/lib/python2.6/site-packages/gtk-2.0/gtk/_lazyutils.py

Alignment trap: python (2412) PC=0x40bfa3c4 Instr=0x280069c0

Does anyone have any ideas why it chokes at deprecation.pyo?????
Thanks
Ed
