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

[Kaushal]

I just rebuilt emacs-24.4 tag from git while glib 2.40.00 is installed. But the same results; gfilenotify doesn't work this time. The last time it worked, it was the same RHEL 5.10, glib 2.40.00 and emacs 24.4. Here is the config.h (renamed) created for the 24.4 build: https://dl.dropboxusercontent.com/u/10985/config-emacs-24.4.h

Is there anything else that gfilenotify depends on? Can I test something from the terminal to verify glib installation that would make gfilenotify work?

Thanks!

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.
