There seems to be a packaging error for AG 3.0.1 on the Intel
Macs. On installing & running the AG toolkit, nothing happens.
Brief investigation reveals that the proximate cause of failure
is the following error message:
"""
ImportError: No module named AGNodeService_client
"""
Further investigation shows that this is true - there is in
fact no such module included, anywhere in the provided code.
Nor, indeed, do any of the functions which are called from
this module exist either.
Comparison with the Linux client reveals that the directory
AccessGrid/AccessGrid/interfaces/
has been entirely omitted from the intel mac package.
Copying the files over from Linux does seem to allow
AG to work correctly, at least insofar as it will connect
to a venue server, and display video from the iSight
camera. I haven't been able to test any further yet.
However, a frankly alarming number of error messages
appear on the console, starting with
Traceback (most recent call last):
File
"/System/Library/Frameworks/Python.framework/Versions/2.3/lib/python2.3/plat-mac/argvemulator.py",
line 76, in callback_wrapper
raise 'Cannot happen: AE callback without handler', (_class, _type)
Cannot happen: AE callback without handler: ('tvea', 'ppao')
AE error: (-1, 'queue element not found during deletion')
in High Level Event: '0x61657674' '0x70706f61'
Traceback (most recent call last):
File
"/System/Library/Frameworks/Python.framework/Versions/2.3/lib/python2.3/plat-mac/argvemulator.py",
line 53, in lowlevelhandler
AE.AEProcessAppleEvent(event)
Error: (-1, 'queue element not found during deletion')
and continuing with a series of further Tracebacks,
all due to
socket.error: (4, 'Interrupted system call')
I don't know if there are any further files missing from
the release which are causing these errors.
