The report came in from Janina Sajka: 64-bit Firefox on Linux does not participate in accessibility with 64-bit AT-SPI.

Firefox and Orca works for me on Ubuntu 8.10 alpha 6 x64.

I've seen this happen if you download the 32-bit version of Firefox and run it on a 64-bit machine. My 64-bit version of FF is working for me (with Orca and with Accerciser) in 64-bit Ubuntu Intrepid.

On Fedora x64, libatk-bridge.so is in /usr/lib64/gtk-2.0/modules
So it didn't be loaded.

I don't know why libgail.so can be loaded.

Workaround:
sudo ln -s /usr/lib64/gtk-2.0 /usr/lib/gtk-2.0
Logout and re-login. Firefox will be accessible.

On Ubuntu 64, /usr/lib64 is a link to /usr/lib, so it works.

Comment 5

[Janina Sajka]

The symbolic link from /usr/lib64 to /usr/lib is probably not a good idea on Fedora as there is a separate tree of 32-bit modules in /usr/lib, including libatk-bridge.so when at-spi.i386 is installed. Note that Fedora supports having both at-spi.x86_64 and at-spi.i386 installed. 

We successfully rebuilt the Fedora Firefox rpm with Ginn's patch, but the rpm would not install, yielded an unpack error. So, I've updated Red Hat bug 445550: https://bugzilla.redhat.com/show_bug.cgi?id=445550 with this information, pointing them back here for additional help.

Attachment: Same as Ginn's patch, except order is /usr/lib64 then /usr/lib

On Fedora the patch is applied against xulrunner, which is a separate package on Fedora. It's now working.

[Ginn Chen]

Janina,
the sequence doesn't matters, because 32-bit library couldn't be loaded by 64-bit Firefox anyway.

But for Linux x64, put /usr/lib64 before /usr/lib sounds not bad.
I'll take your patch when I commit it.
