bug#20441: 24.5; Auto revert mode does not work

Thanks. glib looks like the culprit.

When filenotify used to work, I had glib 2.40.00 installed on RHEL 5.10.

Then I upgraded to glib 2.44.00 last week (also rebuilt emacs after that) in efforts to fix a frame issue I am still facing ( http://emacs.stackexchange.com/q/10745/115 ). The upgrade didn't fix that issue and it seemed that it didn't break anything so I stayed at that version.

But looks that that broke the gfilenotify functionality.

Now, I did make uninstall on glib 2.44.00 and reinstalled glib 2.40.00 and rebuilt latest emacs from master. But that did not fix the gfilenotify issue. I don't know what else I can look into.

Here is the requested src/config.h after reverting back to glib 2.40.00 and rebuilding emacs from master: https://dl.dropboxusercontent.com/u/10985/config.h

Thanks for the help!

Which Linux distribution are you using? Which glib version?

What are the configure options of your Emacs build? Pls show src/config.h.

Best regards, Michael.
