    To make libscg work on almost all Linux systems, I had to work hard.

    Give a better advice!

    Your mail does not help anybody, why do you send it this way?

    So what do you suggest instead?

    Missing binary compatibility on Linux causes me a lot of headaches.

    The only reason for this problem besides problems with the include files
    could be the possible fact that someone from the Linux kernel team learned
    that the correct errno for an illegal IOCTL is _not_ EINVAL but ENOTTY

    ... _and_ cdrecord is run on such a Linux kernel that does not understand
    the SG_IO ioctl or the ioctl changed its parameter.

    Would you call this a nicely backwards comapatible driver?
