[nflug] debian kernel upgrade?

[Stephen Burke]

Hello all,

Sorry for the length of this, but the situation, briefly is that I am 
trying to get my logitech quickcam 3000 pro to work on a recent elive 
(debian etch, apparently) laptop install. Here are various outputs I had 
after installing the pwc with a .deb but before trying the rmmod 
maneuvers mentioned below:


lsmod:

videodev                9632  1 pwc


dmesg:

Linux video capture interface: v1.00
pwc Philips webcam module version 9.0.2-unofficial loaded.
pwc Supports Philips PCA645/646, PCVC675/680/690, 
PCVC720[40]/730/740/750 & PCVC83
0/840.
pwc Also supports the Askey VC010, various Logitech Quickcams, Samsung 
MPC-C10 and
  MPC-C30,
pwc the Creative WebCam 5 & Pro Ex, SOTEC Afina Eye and Visionite 
VCS-UC300 and VC
S-UM100.
pwc Logitech QuickCam Pro 3000 USB webcam detected.
pwc Registered as /dev/video0.
usbcore: registered new driver Philips webcam

lsusb:

An ubuntu forum suggests this answer:

Re: Phillips Webcam Issues (pwc module)
Tracked down a bit more info on the problem. Grey output is a known 
issue on the 2.6.12 kernel. I found a fedora bugzilla report on the 
issue [1] as well as information on the pwc driver mailing list from 
August [2].

I'm not sure when this plans to be fixed, but their is a workaround 
(worked for me anyway).

1) Download pwc-10.0.7a.tar.bz2 from the pwc website [3]
2) rmmod pwc #remove the old module, if loaded.
3) Decompress the file, make, and make install the new module.
4) modprobe pwc # load the new module
5) unplug, and plug back in your usb webcam, and your good to go

When I try to make, I get:

# make
make -C /lib/modules/2.6.12/build 
SUBDIRS=/home/qfwfq/download/pwc/pwc-10.0.12-rc1 modules
make: *** /lib/modules/2.6.12/build: No such file or directory.  Stop.
make: *** [all] Error 2



A debian-devel list suggests this:

   1.  Removing any existing pwc module from the debian-supplied kernel:

     find /lib/modules -name 'pwc.*' -exec rm -rf \{\} \;
     rmmod pwc

   2.  Setting up module-assistant:

     apt-get install module-assistant
     m-a prepare

   3.  Downloading and building the external sources:

     apt-get install pwc-source
     m-a build pwc-source

   4.  Installing the built module:

     m-a install pwc-source
     depmod -a
     modprobe pwc


When I get to "m-a build pwc-source" I get this blue terminal that says

"Bad luck, the kernel headers for the target kernel version could not be 
found and you did not specify other valid kernel headers to use"

and:

────────────────module-assistant, error message───────────────────┐
      │ 
   │
      │ If the running kernel has been shipped with the Debian 
   │
      │ distribution, please install the package linux-headers-2.6.12. 
If │
      │ your kernel source tree (or headers) is located in some 
non-usual │
      │ location, please set the KERNELDIRS environment variable to the 
   │
      │ path of this directory, or (alternatively) specify the source 
   │
      │ directory we build for with the --kernel-dir option in 
   │
      │ module-assistant calls.


then:

# apt-get install linux-kernel-headers-2.6.12
Reading package lists... Done
Building dependency tree... Done
E: Couldn't find package linux-kernel-headers-2.6.12

So, I'm thinking perhaps I should just try to upgrade to a more recent 
kernel, but every time I've tried rolling my own (for gentoo installs 
and stuff) it takes forever and then fails to work anyway.

My question, finally is this: Is there an easy way to upgrade a debian 
kernel with a minimum of wailing and gnashing of teeth?

Thanks,
S.
