Re: [gamin] gamin issue with FAMMonitorFile on CentOS5.1.

[Vitaliy Ivanov <vivanov softservecom com>]

I'm using it from rpms under CentOS 5.1. But for experiment I just
downloaded gamin-0.1.9 and built it - absolutely the same problem.

It's interesting as fam examples are still working. For experiments I
played with:

http://www.linuxdevcenter.com/pub/a/linux/2004/12/16/fam.html

and their examples:

http://www.linuxdevcenter.com/linux/2004/12/16/examples/fam_examples.tar.gz

but my application is not. So I starting to think it's something with
it.

Do you have any other methods to debug it. I used the docs from:

http://www.gnome.org/~veillard/gamin/debug.html

But it didn't show anything else that I mailed to you already.
