Missing dependencies during install hplip 2.8.6

--- you wrote ---
warning: Missing REQUIRED dependency for option 'parallel': ppdev (ppdev - Parallel port support kernel module.)
...
But I have still problem with the last dependency. I can't find package where ppdev is.
---

It is a kernel module providing user-space access to the parallel port (PARPORT) device and probably doesn't have a separate package.

The command:
$ lsmod|grep ppdev
will tell you if that module is available.

Checking the kernel config (probably in /boot/config-*) for CONFIG_PPDEV=y will tell you if it is built in, CONFIG_PPDEV=m results in the ppdev module being generated when the kernel is built.

I'm not sure if HPLIP will detect the functionality if it is built in.

Hi Bruce,
I executed the command $ lsmod|grep ppdev. Here is a result:

I think there is not ppdev. When checked /boot/config-* I found CONFIG_PPDEV=m. I'm not sure what it is mean. I'm begginer with linux. Does exist any possibility how corect it? Could affect it a parallel port setting in Bios? In bios I have parallel port in SPP mode now.

Ya, it does not look like ppdev is loaded (did not appear in the output
of lsmod), but it should be available (is configured to be a module).

For comparison, here is the output for my system:

bsass@onegee:~$ lsmod|grep ppdev
ppdev 8676 0
parport 33868 3 ppdev,lp,parport_pc

What it tells me is the ppdev module is loaded and the parport module is
being used by the ppdev, lp, and parport_pc modules.

Check to see if you have the ppdev module installed. It should reside
at /lib/modules/*/kernel/drivers/char/ppdev.ko (where the "*" is
replaced with a string identifying your kernel, e.g.,
2.6.24-something).

If ppdev.ko does not exist: the kernel config you found is not for the
kernel you are running, or perhaps the module actually does reside in a
separate package (at least you now know the name of the file you need,
ppdev.ko, which should help you locate the package). If it does exist,
it is not loaded. In either case it is probably best to take the info
you now have and ask through your distros support mechanism what the
best way to proceed is.

I don't think so, but it has been years since I've looked at my BIOS
settings or delved into what effect they can have.

I used a command modinfo ppdev and here is an output:

ilename: /lib/modules/2.6.24.4-desktop-3mnb/kernel/drivers/char/ppdev.ko.gz
alias: char-major-99-*
license: GPL
depends: parport
vermagic: 2.6.24.4-desktop-3mnb SMP mod_unload 686

Then used a command modprobe ppdev and then lsmod | grep ppdev

ppmod appeared and hplip installation finished without any errors. But after I restarted PC and try lsmod | grep ppdev nothing appeared. I thing that modprobe adds ppdev module not permanently. Can you help how add it permanently?

If you aren't using a parallel printer you don't need to load the ppdev module. Either way this wont stop the install of HPLIP. If you need the ppdev module you load that by usually adding it to the /etc/modules files. Depending on how mandriva does the modules--you may need to check the mandriva forums or docs for how this is done exactly. You can load the module temporarily by running

modprobe ppdev

But it's not required to load the module to install hplip, it should continue correctly.

Unfortunately I need to use parallel printer. I found that the ppdev is only depend module. Main module is parport and it is loaded. When I restart PC and use lsmod I get this:

parport_pc 31716 0
parport 31592 1 parport_pc

after it I use modprobe ppdev and check correct loading by lsmod. I get:

parport_pc 31716 0
parport 31592 2 ppdev,parport_pc

I don't understant this information. I thing that solution could be edit /etc/modules. I check it but it is empty. Can you tell me some about syntax of it? When I wrote only ppdev nothing happened.

It appears that mandriva uses the /etc/modules.conf rather than /etc/modules. You could try that--however because of the many variations of linux I can't be for sure. For additional help you may want to try the mandriva forums. This might be a good place to start: http://mandrivausers.org/

Hope this helps!
