lipo: can't figure out the architecture type of

[Vijayendra Bapte]

Hi,

I am getting an gcc compilation error while installing FSEvents
(http://pypi.python.org/packages/source/p/pyobjc-framework-FSEvents/
pyobjc-framework-FSEvents-2.2b1.tar.gz) package on my Mac (OS X
10.4.11, Intel Core Duo 32 bit processor, Python2.6.1, gcc: i686-apple-
darwin8-gcc-4.0.1)

gcc failed while building the "FSEvents._callbacks" extension on $
python setup.py install

here is the error trace...

Finally after doing lots of search on google, I found that there is no
support of FSEvents for Tiger. It wraps some API's that aren't
available on Tiger systems.

Alternatives:

(1) Using kqueue/kevent: It might be possible to emulate the behavior
using kevent/kqueue. But the problem here is, it does not provide the
granularity as FSEvents i.e I you cannot detect which file is modified/
added/deleted inside the marked directory.

(2) The other alternative is polling for changes.
