[gentoo-user] hald won't start

[Alexander Skwar]

Hello!

Since this morning, I'm unable to start hald. This is in so
far a pretty big problem, as this means, that I cannot boot :|

After setting HALD_VERBOSE=yes in /etc/rc.conf, I found that
it filled the syslog with a lot of lines like

  device_info.c:984: Unhandled rule (0)!

Searching the archive of this list, I found a thread started
by Mick on July 14; see eg. 
http://www.nabble.com/forum/ViewPost.jtp?post=11596495&framed=y

In this thread, Alessandro del Gallo suggested to move files
from /etc/udev/rules.d out of the way, to figure out what's
exactly causing the issue. I did that, and even when I have
*no* files at all in rules.d anymore, I cannot start hald by
running "/usr/sbin/hald --daemon=no --verbose=yes".

>From what other sources is hald fetching rules? Ie. what
other file/directory might I need to empty?

Thanks,
Alexander

I found that this bug 172830 <http://bugs.gentoo.org/show_bug.cgi?id=172830>.
This bug has to do with libgphoto2.

Yesterday, I set the environment variable CAMERAS to only "directory",
as I don't have any camera requiring special treatment. When libphoto2
is build with CAMERAS=directory (and nothing else), it'll create bad
HAL files.

Workaround: Either don't set CAMERAS at all (meaning that all cameras
will be built), or add at least one "dummy" camera. I took the 2nd
solution; ie. in my make.conf, I now have: CAMERAS="ptp2 directory".
After having rebuild libgphoto2, the  system starts up fine.

Have a nice day,

Alexander Skwar
