libdc-1394-22 gives "libdc1394 error: Failed to initialize libdc1394" when loaded.

Thank you for taking the time to report this bug and helping to make Ubuntu better. Please answer these questions:
1. What program did you use that caused troubles?
2. If none, what specific steps should we take to recreate this bug? Be as detailed as possible.
This will help us to find and resolve the problem.

This could be a problem with the kernel modules, more specifically with the new firewire stack.

Please send us the output of

lsmod | grep 1394
lsmod | grep firewire

I believe that the latest sources have been patched regarding the new stack.

It could also be related to the access to the raw1394 device, but I don't know if the packages touch /dev/ in any way.

No specific program is needed, just something that loads the lib seems
to trigger this. It can be reproduced with dc1394_reset_bus or
coriander (which afterwards segfault).

Let me know what more I can do to help track down the problem.

Thank you for helping. I am also working upstream and I will test this after the karmic release tomorrow. I let you know and I will mark it later.

Have similar problem on Ubuntu 9.10 with latest updates.
Found solution:

There is no file /dev/raw1394 (driver is not loaded)!

$ sudo modprobe raw1394

After this check your permissions on device /dev/raw1394
You must have rw access to this device!
For me it looks like:

$ ls -la /dev/raw1394

crw-rw---- 1 root root 171, 0 2009-10-30 11:34 /dev/raw1394

On my Ubuntu 9.04 system this looks like:

crw-rw---- 1 root disk 171, 0 2009-10-30 11:34 /dev/raw1394

Thank you! This solves my problem. Any idea why raw1394 isn't loaded?
 I would expect it to be by default.

/Gustaf

Finally, to make changes permanent, i added raw1394 to /etc/modules file:

$ echo "raw1394" | sudo tee -a /etc/modules

and created udev rule to change group of /dev/raw1394 device:

$ echo 'KERNEL=="raw1394", GROUP="disk"' | sudo tee -a /etc/udev/rules.d/50-raw1394.rules

I will take this with debian and make sure to embed your comments. Thank you for the help.

Needs to forward to debian (not upstream)

I also remembered that there was a discussion on the upstream about it:

http://sourceforge.net/mailarchive/message.php?msg_id=4AB735F3.20402%40enseirb.fr

and here:

I installed the latest libdc-2.2.0 and on running :
1. Coriander, I get the message: libdc1394 error: Failed to initialize libdc1394, Segmentation fault
2. Hello World I get: libdc1394 error: Failed to initialize libdc1394

The raw1394 has read-write permissions.
The outputs of
1. lsmod | grep 1394 is
raw1394 25298 0
video1394 15684 0
ohci1394 30260 1 video1394
ieee1394 94771 3 raw1394,video1394,ohci1394

I donot get anything when I type lsmod | grep firewire

I am unable to understand what the issue is. Any help would be greatly appreciated. Thanks !
