- Getting the correct include files for the sg interface can be an ordeal.
- In a perfect world, one would just write:
- #include <scsi/sg.h>
- #include <scsi/scsi.h>
- This would include the files found in the /usr/include/scsi directory.
- Those files are maintained with the GNU library which may or may not
- agree with the kernel and version of sg driver that is running. Any
- many cases this will not matter. However in some it might, for example
- glibc 2.1's include files match the sg driver found in the lk 2.2
- series. Hence if glibc 2.1 is used with lk 2.4 then the additional
- sg v3 interface will not be visible.
- If this is a problem then defining SG_KERNEL_INCLUDES will access the
- kernel supplied header files (assuming they are in the normal place).
- The GNU library maintainers and various kernel people don't like
- this approach (but it does work).
- The technique selected by defining SG_TRICK_GNU_INCLUDES worked (and
- was used) prior to glibc 2.2 . Prior to that version /usr/include/linux
- was a symbolic link to /usr/src/linux/include/linux .
-
- There are other approaches if this include "mixup" causes pain. These
- would involve include files being copied or symbolic links being
- introduced.
-
- Sorry about the inconvenience. Typically neither SG_KERNEL_INCLUDES
- nor SG_TRICK_GNU_INCLUDES is defined.
