Dexxa Webcam with qc-usb-0.6.2

    Hi,

    I am trying to install my USB Dexxa Webcam on a Linux Debian Sid kernel 2.6.7 with qc-usb-0.6.2 . I have a version conflict problem and I do not know how to solve it.

    When I launch the (wonderful) installation script :

    % ./quickcam.sh MODULE_DIR=/lib/modules/2.6.7/kernel/drivers/usb LINUX_DIR=/usr/src/linux-2.6.7/

    Everything goes well until this step :

    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...
    insmod: error inserting './quickcam.ko': -1 Invalid module format
    === Leaving root mode ===
    quickcam: version magic '2.6.7 preempt K7 gcc-3.3' should be '2.6.7 preempt K7 gcc-2.95'
    [!] The QuickCam driver failed to load!

    How can I obtain '2.6.7 preempt K7 gcc-2.95' ? Do I have to type some commande line to change the version ?

    Thank you very much for your help.

    Michal.

      You have gcc-3.3 installed which was used
      for compiling qc-usb, but the kernel has been
      compiled with gcc-2.95 (as Debian kernels
      usually are). Install gcc-2.95 and remove gcc-3.3
      if needed.
      When you type "gcc -v", it should print 2.95
      and something.
      You could also try to load with option "-f" to
      modprobe which should force the module
      to be loaded, but I'm not sure if it works.

      On Debian the command to install gcc-2.95 is
      apt-get install gcc-2.95
      but you may need to remove the other version
      to make 2.95 the default version (or give
      quickcam.sh the correct compiler command as argument, something like CC=gcc-2.95 probably)

      HI,

      I had also the same problem with similar error messages with a VV6410 sensor in the Dexxa Webcam.

      I used the patch in line 33 of the file qc-vv6410.c and it worked!

      I replaced the line
      #define QCEGA_MODE 0
      with
      #define QCEGA_MODE 1

      See also Bug Request ID 1101276 in the Bugs section in this project site.

      Good luck! Kan.
