Q: I get the following error message:
   qc-driver.c:51: linux/version.h: No such file or directory
   qc-driver.c:52: parse error
   or
   .../include/linux/config.h:4: linux/autoconf.h: No such file or directory
   or
   sed: can't read /usr/src/linux/Makefile: No such file or directory
   or
   Makefile:26: /usr/src/linux/.config: No such file or directory

A: You must install Linux kernel source code corresponding
   to the kernel you will be running with the camera driver.
   The source must be configured and depencies must have been
   created. Typically you can just install the kernel source
   package that comes with your distribution. If you're instead using
   virgin kernel in /usr/src/linux-x.y.zz, you must first copy
   kernel configuration file to /usr/src/linux-x.y.zz/.config,
   then go to the directory and run "make oldconfig" and "make dep".
   This should create the missing linux/version.h file.
   Some more help for Redhat/Mandrake users:

   If you get a lot of errors on mandrake or red hat when
   you do a make, it may be because you didn't install a
   full development version, meaning your kernel sources
   are not there.
   This worked for me

   urpmi kernel-source
   urpmi kernel-headers
   urpmi kernel-doc

   urpmi is your friend, it will find the CD that it needs
   to get this. Some rpms may be installed already, big
   deal, do this then do a make, it worked on mandrake 8.2!

------------------------------------------------------------
Q: And finally, I look for /dev/video* (to set the videodev on
   gnomemeeting) and I haven't any videodevice.

A:
   mknod /dev/video0 c 81 0
   chmod a+r /dev/video0
   ln -s /dev/video0 /dev/video

------------------------------------------------------------
Q: quickcam.c:2099: too few arguments to function `remap_page_range_R2baf18f2'
   Damian Ivereigh posted a patch to be able to compile
   the driver for RedHat 9.0 but I don't know how to do
A: Due to qc-usb 0.5.1, this should be now fixed. If you
   still encounter this problem, and
   if you're using qc-usb, just compile it with command
   USER_OPT=-DHAVE_VMA=1 make all
   Otherwise (if you're using older qce-ga):
1. Download qce-ga-0.40d.tar.gz package and save
   the patch
   wget http://www.ee.oulu.fi/~tuukkat/quickcam/qce-gq-rh9.patch
   wget http://www.ee.oulu.fi/~tuukkat/quickcam/qce-ga-0.40d.tar.gz
2. Extract the package:
   tar xvfz qce-ga-0.40d.tar.gz
3. Enter the source directory
        cd qce-ga-0.40d
4. Apply the patch:
   patch -s -p1 < ../qce-gq-rh9.patch
5. patch complains that the patch is reversed. Answer yes:
Reversed (or previously applied) patch detected!  Assume -R? [n] y
6. Then compile and install the driver normally
   make
   ./quickcam.sh

------------------------------------------------------------
Q: I don't have permissions for /dev/video?
A: Easiest way to add permissions is to do
   chmod a+rw /dev/video?
   as root. Altenatively, especially on Debian, users belonging
   to the "video" group can access video devices. In this case,
   you might instead prefer issuing
   addgroup <yourlogin> video
   as root and then login as normal user. Check in which groups
   your are in with
   id -a

------------------------------------------------------------
Q: My log files keep filling up (but the driver works fine)!
A: use "qcset debug=0" to disable all possible messages.
   If it doesn't help, send e-mail to mailing lists showing
   the exact error message that fills your logs.
   (especially "frame lost" message is uninteresting, it is
   known to happen with some programs and will be fixed later.

------------------------------------------------------------
Q: quickcam.o: kernel-module version mismatch
      quickcam.o was compiled for kernel version 2.4.18
      while this kernel is version 2.4.18-686-smp.   
A: Then edit "Makefile" in the kernel source directory and change the line 4
   from
      EXTRAVERSION =
   to
      EXTRAVERSION = -686-smp
   --or if this doesn't help--
   Go to /usr/src/linux-2.4/include/linux/version.h and change the
   UTS_RELEASE to match the output of "uname -r" on the command line
   (should be 2.4.18-686-smp). Then recompile the module and then the
   insmod will work perfectly :) [from Mark]

------------------------------------------------------------
Q: I want to reverse engineer an USB camera. How?
A: Run *ugh* Windoze *cough* drivers with a USB stream
   capture program, like http://sourceforge.net/projects/usbsnoop/
   Then send the same commands to the camera from Linux.

------------------------------------------------------------
Q: I added IEEE1394 card and now Quickcam doesn't work?
A: The card driver overwrites /dev/video0..2, use
   insmod ./quickcam.o video_nr=3
   and then /dev/video3 with Quickcam.
   Create /dev/video3 with mknod if necessary.

Error:
   >make[2]: Entering directory `/opt/uClinux-dist/uClibc'

   >You didn't read the README, did you... =)
   >Choose a configuration file in extras/Config/ and then run
   >  ln -s ./extra/Configs/Config.<arch> ./Config

A:    The solution to this seems obvious. I "cp ./vendors/Lineo/uCdimm/config.uClibc
   ./vendors/Lineo/uCsimm" and make again with the same settings as above. The
   library compile bombs out a little further along...

A
 recent posting suggests a solution. Rather than copy individual missing files,
I untared an older uClibc-snapshot into "./uClibc" and then overcopied with the
uClibc-0.9.10 tree. The make goes further still and stops with...
use the uClib of uClinux-dist-20050311.tar.gz replace it,because I can make it in that.

Now I'm lost. I made a wild guess which is probably wrong and created a
directory called ./uClibc/lib and recompiled...

My host system is RH7.2 and I've installed m68k-elf-tools-20020218.tar.gz under
"/" and uClinux-dist-20020306.tar.gz under "/opt".

/*intrenet A
I think you have'nt installed the toolchain properly.
Simply type arm-linux-gcc in one linux console.
if still gives the error "command not found",reinstall
the toolchain.
If it still doesn't work, you may have to modify the
PATH environmental varaiable to include the
toolchain's path to it.*/
