[Pyobjc-dev] Install pyObjC on Snow Leopard / Quartz CGEventTapCreate

[schneo <sc...@gm...>]

Hello,

I’m porting an Open Source Python recording/podcasting application i wrote
on Windows to Mac OS X (i’m pretty new to this platform).
http://sites.google.com/site/audiovideocours/english-home
Everything is now finished except the essential events hook which is used
for synced screen capturing and finishing recording (and that’s where pyObjC
communicate with Quartz for the events tap).

Unfortunately i had errors here and after searching i saw there’s a bug in
the currently implemented pyobjc lib shipping with Snow Leopard:
https://sourceforge.net/mailarchive/message.php?msg_id=22904885

So far i fail at installing the new corrected version of pyobjc. What would
be the simplest way for me to have a good version of pyobjc for my purposes
? (if possible i’d like to stay with the python version shipping with OS X)

So far i tried,

1) to find the official pyobjc sources file (shipped by Apple) and make the
changes you describe on that file (after a backup of those files) but i
can’t find them on Snow Leopard.

2) to install pyobjc form the pyobjc website

a) i did a trunk checkout and tried “python setup.py install” which ended up
in (see more details at the end of the mail)

[...]

Requirement.parse('pyobjc-framework-ServiceManagement==2.4a0')

b) i tried “easy_install pyobjc”

3) i tried installing pyobjc from macports

This did apparently install a the macport python26 and pyobjc libs in
“/opt/local/var/macports/software” without errors:
$ ls
[...]
py26-pyobjc
py26-pyobjc-cocoa
python26

if i launch in a shell “python2.6” or
"/opt/local/var/macports/software/python26/2.6.6_3/opt/local/bin/python2.6",
i can do an “import Foundation” but an “import Quartz” states that there’s
no library of that name.

4) Is it possible to just drag and drop a pyobjc folder in my dev. folder so
that i’m sure it’s going to use it or is it necessary to build something?

All help would be greatly appreciated  and thanks a lot for your work on
this essential bridge :)

PS: Is the pyobjc shipping soon in OS X Lion will have this bug fixed?

Thanks again.
Francois.
