Bug Description

The internal data structure (struct _ipp_s) of ipp_t in the CUPS API (cups/ipp.h) is private (not intended to be directly accessed from non-CUPS programs). In CUPS 1.6.0 and earlier it was still accessible as it was unconditionally available in cups/ipp.h. From CUPS 1.6.1 on it is packed into a conditional making it only available for CUPS' own programs.

The correct solution is not using this internal structure any more, the quick workaround is compiling HPLIP with the "-D_IPP_PRIVATE_STRUCTURES=1" compiler argument.

I have found the problem in prnt/cupsext/cupsext.c but it probably occurs also in other files.

HPLIP is 3.12.6 on Ubuntu Quantal.

Hello Till,

Thanks for the update. We will make use of the accessor functions in the future HPLIP versions as suggested in CUPS ipp.h, however for our next release HPLIP-3.12.10 we have enabled the _IPP_PRIVATE_STRUCTURES macro.
