libgphoto2 is a library that can be used by applications to access
|
||
|
|
various digital cameras.
|
||
|
|
|
||
|
|
The resulting package checks /var/log/packages for your installed udev
|
||
|
|
version and generates udev rules in the post-install stage. For those
|
||
|
|
of you still using the old hotplug subsystem, it also adds the file
|
||
|
|
/etc/hotplug/usb/usbcam during the packaging and appends some text to
|
||
|
|
/etc/hotplug/usb.usermap in the post-install stage. This appending is
|
||
|
|
not normally something that we would do with any of our scripts, but in
|
||
|
|
this case, it should be completely harmless; however, a backup copy of
|
||
|
|
the file is left in the same directory just in case.
|
||
|
|
|
||
|
|
Since version 2.3.1 build 3, there are two different groups granting
|
||
|
|
access to your digital camera for non-root users via udev and hotplug.
|
||
|
|
|
||
|
|
From now on the udev rules generated during install set device ownership
|
||
|
|
to the 'plugdev' group. If this group does not yet exist (users of HAL
|
||
|
|
should have this group already), you will need to create it and add any
|
||
|
|
users that may access the camera. A recommended way for adding the 'plugdev'
|
||
|
|
group would be:
|
||
|
|
|
||
|
|
/usr/sbin/groupadd -g 83 plugdev
|
||
|
|
|
||
|
|
Hotplug users still have to use the group 'camera' and add any users that
|
||
|
|
should be permitted to access the camera to this group. Alternatively,
|
||
|
|
you can edit the included doinst.sh file to change "group plugdev" to
|
||
|
|
"group users" (if you're using udev) or edit /etc/hotplug/usb/usbcam after
|
||
|
|
the package is installed and change "camera" to "users" (if you're using
|
||
|
|
hotplug) if you want all users to have access to cameras.
|
||
|
|
|
||
|
|
The resulting package *should* work without any manual setup, but in our
|
||
|
|
testing here, it seems that some cameras aren't recognized by the installed
|
||
|
|
udev rules. There is at least one reliable report of a change that *may* be
|
||
|
|
needed if you're using udev-097 from Slackware 11.0:
|
||
|
|
|
||
|
|
This:
|
||
|
|
BUS!="usb*", GOTO="libgphoto2_rules_end"
|
||
|
|
should perhaps be this:
|
||
|
|
SUBSYSTEM!="usb*", GOTO="libgphoto2_rules_end"
|
||
|
|
|
||
|
|
However, if the rules installed by libgphoto2 work for you, don't change
|
||
|
|
anything - this should only be done if they don't work. Note that this is
|
||
|
|
*not* a bug in the build script or implementation - we just use the provided
|
||
|
|
tools with libgphoto2 to generate the udev rules; as such, any bug reports
|
||
|
|
with the udev rules should go to them (feel free to CC our -users list).
