Hi All!
I am trying to use pyocc from C++, with the embedded python api. If I
run the app from XCode, I got the following errors when initializing
SimpleGUI:
Traceback (most recent call last):
File "???", line 7, in <module>
File "/Users/istvancsanady/Documents/workspace/butterfly/src/pool.py",
line 12, in <module>
display, start_display, add_menu, add_function_to_menu = init_display()
File "/Library/Python/2.6/site-packages/OCC/Display/SimpleGui.py",
line 173, in init_display

line 62, in set_CSF_GraphicShr
p2 =
subprocess.Popen(['grep','-i','libTkOpenGl'],stdin=p1.stdout,stdout=subprocess.PIPE)

File

line 1101, in _execute_child
data = os.read(errpipe_read, 1048576) # Exceptions limited to 1 MB
OSError: [Errno 4] Interrupted system call
Or the other one:
Traceback (most recent call last):

line 12, in <module>

line 950, in _syscmd_uname
output = string.strip(f.read())
IOError: [Errno 4] Interrupted system call
And another one:
Traceback (most recent call last):
File "???", line 7, in <module>
File "/Users/istvancsanady/Documents/workspace/butterfly/src/pool.py",
line 12, in <module>
display, start_display, add_menu, add_function_to_menu = init_display()

line 64, in get_display

File "/Library/Python/2.6/site-packages/Xlib/support/unix_connect.py",
line 43, in <module>

File

line 1194, in uname
processor = _syscmd_uname('-p','')
File
"/System/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/platform.py",
line 950, in _syscmd_uname
output = string.strip(f.read())
IOError: [Errno 4] Interrupted system call
And the strangest thing: sometimes IT WORKS! If I start the app from
Terminal or Finder, everything works always fine... Any ideas?
