    you have probably more than one version of sg.h installed on your
    machine; the "Suse default" for example is to put a really old version
    of sg.h in /usr/include/scsi, and a recent version in

    Run "find /usr . -name sg.h -print" to get a list of all files named

    (Output for the Linux box I'm using to write this mail:

    /usr/i486-glibc20-linux/include/scsi/sg.h )

    Rename all of them except one, and create symlinks pointing to the one
    file you keep. referably, you should keep sg.h from the kernel 2.2.16

            cd /usr/include/scsi
            mv sg.h sg-old.h

    then, for the example output shown above:

            ln -s /usr/src/linux-2.2.13.SuSE/include/scsi/sg.h sg.h

    or, for your machine:

            ln -s /usr/src/include/scsi/sg.h sg.h
