    Greetings,

    I have the following simple compilation problem with missing #defines.
    Searching on the web found some kernel patches, but nothing that
    explained why these #defines went away or what their
    replacement/equivalent is now. Can anyone give a new parallel port user
    an explanation of the development history and suggest a fix?

    System:
            2.4.2 kernel redhat linux
    Problem:
            Image software using parport doesn't compile
            ( http://www.ee.uwa.edu.au/~braunl/improv/ )
    Error:

    ../../ximprov-4.0/v4l/eyecam.c:126: `PARPORT_CONTROL_INTEN' undeclared
    (first use in this function)
    ../../ximprov-4.0/v4l/eyecam.c:126: (Each undeclared identifier is
    reported only once

    ../../ximprov-4.0/v4l/eyecam.c:621: `PARPORT_CONTROL_DIRECTION'
    undeclared (first use in this function)
    ../../ximprov-4.0/v4l/eyecam.c: In function `set_output_mode':
    ../../ximprov-4.0/v4l/eyecam.c:628: `PARPORT_CONTROL_DIRECTION'
    undeclared (first use in this function)

    Indeed, these constants don't exist on my system.

    /usr/local/include/linux/parport.h:

    #define PARPORT_CONTROL_STROBE 0x1
    #define PARPORT_CONTROL_AUTOFD 0x2
    #define PARPORT_CONTROL_INIT 0x4
    #define PARPORT_CONTROL_SELECT 0x8

    #define PARPORT_STATUS_ERROR 0x8
    #define PARPORT_STATUS_SELECT 0x10
    #define PARPORT_STATUS_PAPEROUT 0x20
    #define PARPORT_STATUS_ACK 0x40
    #define PARPORT_STATUS_BUSY 0x80
