    error installing quickcam


    Hi,
    i want to install quickcam driver qce-ga-0.40d.tar for my logitech quickcam
    express,after instalation and runing the xawtv it cannot connet to quickcam
    this is the output of ./quickcam.sh:
    Now everything should be well and the driver compiled.
    Let's then try actually loading the fresh driver and testing
    if it works.
    Press Ctrl+C to quit, Enter to continue --->
    To load the driver, I need to know the root password.
    === Entering root mode ===

    I will now try to enable the SysRq key.
    If your computer crashes, you can try pressing:
    Alt + SysRq + S: Emergency Sync (write everything on hard disk)
    Alt + SysRq + U: Unmount all harddisks
    Alt + SysRq + B: Reboot system immediately
    Press Ctrl+C to quit, Enter to continue --->
    Now I finally will try to load the module.
    If you're unlucky, your computer might crash right now!!!!
    Consider long if you really want to continue.
    Press Ctrl+C to quit, Enter to continue --->
    You decided to do it, here we go...
    === Leaving root mode ===
    The driver detected the following supported cameras:
    quickcam: QuickCam USB camera found (driver version QuickCam USB $Date: 2003/12/31 16:15:06 $)
    quickcam: Kernel:2.6.3-4mdk bus:1 class:FF subclass:FF vendor:046D product:0870
    quickcam: Sensor HDCS-1020 detected
    quickcam: Registered device: /dev/video0
    I will be using /dev/video0, if there are more cameras I'll not test them.
    Press Ctrl+C to quit, Enter to continue --->
    Testing if /dev/video0 is correct.
    ls: : No such file or directory
    lr-xr-xr-x 1 root root 10 May 7 15:38 /dev/video0 -> v4l/video0
    ./quickcam.sh: line 547: [: too many arguments
    ls: : No such file or directory
    ls: : No such file or directory
    [!] major number is .
    Usually it should be 81, so there are problems ahead.
    WARNING: I'll try to continue anyway, but this probably will fail.
    Press Ctrl+C to quit, Enter to continue --->
    [!] Bad minor number in , should be 0.
    To correct this problem, remove the bad file and
    recreate it with mknod-command (read man mknod).
    WARNING: I'll try to continue anyway, but this probably will fail.
    Press Ctrl+C to quit, Enter to continue --->

    Right now driver is loaded and ready to run.
    If you like, you can quit now and start using the camera -
    you have good chances that it works, if no problems were detected.
    If you have X Window System running and xawtv installed,
    I can now run it automatically for you.
    You will then also have opportunity to install the driver permanently.
    Press Ctrl+C to quit, Enter to continue --->
    Launching xawtv (press q on xawtv window to quit it)...
    xawtv -noscale -noxv -c "/dev/video0"
    This is xawtv-3.91, running on Linux/i686 (2.6.3-4mdk)
    Cannot open plugin directory /usr/lib/libquicktime
    Did you forget "make install"? You need it because
    libquicktime cannot load plugins out of the sourcetree
    /dev/video0 [v4l]: no overlay support
    v4l-conf had some trouble, trying to continue anyway
    ioctl: VIDIOC_QUERYCAP(driver="";card="";bus_info="";vers ion=0.0.0;capabilities=0x0 []):
    Unknown error 515
    and this is the dmesg output:
    usb 1-1: new full speed USB device using address 3
    quickcam: QuickCam USB camera found (driver version QuickCam USB $Date: 2003/12/31 16:15:06 $)
    quickcam: Kernel:2.6.3-4mdk bus:1 class:FF subclass:FF vendor:046D product:0870
    quickcam: Sensor HDCS-1020 detected
    SCSI subsystem initialized
    quickcam: Registered device: /dev/video0
    imm: Version 2.05 (for Linux 2.4.0)

    /dev/video0 demystified

    Note:Mine is a USB WebCam
    /dev/video0 is entry point to the video hardware
    Make sure ur webcam driver is compatible with the Linux Kernel..or else
    download the latest and recompile
    the do the following at command-line
    #modprobe spca5xx
    (modprobe inserts the webcam driver module into the kernel!!!thereby /dev/video0 comes alive!!!!)
    (spca5xx is a webcam driver whcih supports most webcams...mine was an alien!!!!still worked)
    then check by giving
    #XAWTV

    this should show u the webcam visual
    Iam using Redhat 9....i think fedora core 3 should be better!!!!

    cheers,
    karthik
