    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:

    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.

    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

    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.
