The change to the build flags solves the problem because hpcups and pxljr rely on being able to override jinit_color_converter. I think the fact that they're doing this points out a weakness in the libjpeg API - there should be some better way to register a callback to change the converter instead of hijacking the symbol from the library.
I think that for precise, turning off -Wl,-Bsymbolic-functions will be the right way to fix this. It's possible, but unlikely, that it will cause undesirable behavior regressions elsewhere... ultimately, it can only be a regression if some other package is *trying* to do this symbol interposition, has implemented it poorly, and users are being saved from that bug by symbolic-functions. ** Also affects: libjpeg6b (Ubuntu Precise) Importance: Undecided Status: New ** Also affects: hplip (Ubuntu Precise) Importance: Undecided Status: New ** Also affects: pxljr (Ubuntu Precise) Importance: Undecided Status: New ** Also affects: ghostscript (Ubuntu Precise) Importance: Undecided Status: New ** Also affects: libjpeg-turbo (Ubuntu Precise) Importance: Undecided Status: New ** Changed in: ghostscript (Ubuntu Precise) Status: New => Invalid ** Changed in: hplip (Ubuntu Precise) Status: New => Invalid ** Changed in: libjpeg-turbo (Ubuntu) Status: Confirmed => Triaged ** Changed in: libjpeg-turbo (Ubuntu) Milestone: precise-updates => None ** Changed in: libjpeg6b (Ubuntu Precise) Status: New => Fix Released ** Changed in: libjpeg-turbo (Ubuntu Precise) Importance: Undecided => High ** Changed in: libjpeg-turbo (Ubuntu Precise) Status: New => Triaged -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/777670 Title: wrong colors on HPCLJ 3500/3600 printer after switching to 11.04 To manage notifications about this bug go to: https://bugs.launchpad.net/foomatic-db-hpijs/+bug/777670/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
