I'm sure that the cups maintainers are aware of all this, but it might be of interest to users who all of a sudden can't print, so I'm commenting on the defect.
I was unable to locate a copy of the version 0.12.0-2.1 version of libpoppler5 to downgrade to, so I investigated the issue with the cups source, thinking there might be a simple patch I could apply to the cups source to get it all to work. To be specific, the issue that cups complains about is that it can't run the pdftopdf filter and, when run manually, that filter issues a message similar to this: undefined symbol: _ZN13GfxColorSpace5parseEP6Object Once I downloaded the cups source and figured out which command to issue to build it, the problem became obvious: The poppler guys have changed the function signature of GfxColorSpace::parse to include a pointer to a Gfx object. They also added a similar pointer to the calls to GfxPattern::parse, like is called by methods in P2PPattern.cxx Since it says that P2PGfx.cxx is derived from Gfx.cc from the poppler source, I thought it might prove useful to see what the Gfx.cc source passes to GfxColorSpace::parse, and it passes the "this" pointer in that place. Since the P2PGfx class is not derived from the Gfx class, passing the "this" pointer won't work and trying to derive P2PGfx from Gfx is more work than I'm willing to go to for a quick fix. I was able to get it to work (I could at least print my jobs) by passing NULL pointers in all three places where it expects extra object pointers. However, I expect that approach to be suboptimal. That parameter is likely used for something, although I'm not going to dig into just what at the moment. In any case, there is a version dependency. I don't know if libpoppler5 should have been versioned or what, but the 1.4.2 version of cups is clearly not compatible with it and I believe that the dependencies should be adjusted such that you can't have cups 1.4.2-2 installed at the same time as libpoppler5 0.12.2. !DSPAM:141,4b140dc940091780812483! -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe".
